Types and purpose of ventilation in a log bath. Ventilation in the bath: diagrams, views, building tips and options for the correct configuration (105 photos) Ventilation in the bath layout

In order for bath procedures to bring only benefit and pleasure, two conditions are necessary:

  • high level of temperature and humidity in the steam room;
  • the presence of a sufficient amount of oxygen.

These seemingly mutually exclusive tasks are solved by ventilation in the bathhouse in general and in the steam room in particular. Despite the fact that high humidity and temperature should be maintained in the steam room of the Russian bath, one cannot do without access to fresh (cold) air: oxygen is processed by our lungs, partially burned out by the stove, and carbon monoxide (CO is the chemical formula carbon monoxide).

How to make ventilation in the bath. In the figure, red arrows show the movement of hot air, blue - cold

If you do not organize the replacement of “exhausted” air with fresh air, instead of improving health and increasing efficiency (this is what we go to the bath for), you can get lethargy, weakness and headache at best, and at worst - a hospital bed or even a place in the cemetery.

Properly arranged ventilation provides air circulation, while oxygen enters in sufficient quantities, and carbon monoxide and carbon dioxide are released into the atmosphere. After the end of the bathing procedures, with good ventilation, the steam is actively removed outside the building, and the rooms in which there was previously high humidity dry out. If this aspect was not given sufficient attention, after a couple of years in the steam room, and then in other rooms, the lining rots, the smell of mustiness and sweat appears and gradually increases, and the wood turns into dust. Now, I hope, it is clear whether ventilation is needed in the bath ...


Heating and ventilation of the bath. Please note that the exhaust hole is located at a low height from the floor - as a rule, not higher than 50 cm. With this scheme, exhaust steam is released into the atmosphere. Moreover, the floor in the steam room warms up well

Ventilation in the bath is not needed in only one case: if it is all built of wood and has not been insulated anywhere - neither inside nor outside. In this case, air exchange occurs due to the fact that the wood "breathes". Even in this case, they talk about the presence of natural ventilation in the bath: any wood has pores and cracks through which the outflow / inflow of air occurs, temperature and humidity are regulated. But if there is insulation or moisture / vapor insulation in the bath from rounded logs, then the creation of additional ventilation holes is necessary.

There are three types of ventilation:

  1. mechanical ventilation. In this case, the inflow and outflow of air masses occurs due to artificially created air movement. Air parameters are controlled by technical means.
  2. Natural ventilation: circulation occurs due to the difference in pressure inside and outside the room. This method is possible only if there are "breathing" walls or thoughtfully arranged ventilation vents.
  3. Combined ventilation: simultaneous use of the natural movement of air masses and technical devices(in the simplest case - fans).

The video below shows a variant of combined ventilation.

In a specific case, 100 micron aluminum foil was used in the construction of the ventilation duct.

Bath ventilation device

In the very simple version, the ventilation system of a steam room or bath consists of two (sometimes more) holes in the walls and / or foundation: supply and exhaust. The whole trick is in choosing the location of these holes and in their sizes. Sometimes, to provide more active air exchange, fans can be installed.


Heating and ventilation of the bath. In the simplest case, the exhaust vent is located near the ceiling

There is no single ventilation scheme for a bath: they are too different both in design features and in the materials from which they are made. But there are general rules and some of the most common schemes, adhering to which, you can choose the optimal ventilation for your particular case.

The dimensions of the ventilation openings are calculated based on the volume of the steam room: for one cubic meter ventilated area, the size of the holes should be 24 cm 2.

Despite the fact that the main task in the bath is to maintain high humidity in the steam room and a sufficient temperature level, do ventilation holes too small cannot be: they will not provide the necessary level of air exchange. Exhaust vents must match the size of the supply: if the proportions are violated, air exchange will also be insufficient. In some cases, to speed up the removal of exhaust air and speed up the drying of the bath, two exhaust holes can be made.


To ensure the required air conditions when heating the steam room, special covers / plugs are made on the ventilation ducts that can be opened / closed from the steam room, thereby regulating humidity / temperature / air exchange. Generally speaking, the presence of plugs or covers on any vent facing the street is a must: in winter, cold air actively tends to warm room and the presence of covers or regulators to delay it is necessary.

Where can there be supply and exhaust openings

Most often, at least partially located in the steam room. In this case, the supply hole is made near the furnace at a distance no higher than 30 cm from the floor. The incoming cold air is quickly heated from the furnace and rises. It's quite popular, but not the most The best way organization of ventilation for the bath. Ventilation is much more effective when the supply holes are located in the foundation under the floor (so that rodents do not penetrate through them, the holes are equipped with metal bars). This option solves two problems at once: it delivers fresh air to the bath, and also effectively dries the floors and walls after the procedures are completed. The floor boards, in this case, are not laid close, but with a small gap for the free passage of air. If you don’t want to leave gaps in the floor (although this is very good for a bath), you can make several ventilation holes in the floor, covered with wooden grates. The air movement in this case will not be so active, more powerful fans may be needed, but the circuit will remain operational.


When planning the supply vents in the foundation, keep in mind that the air in the bath should come from the street, and not from the underground, otherwise it will have a musty smell. To organize air intake from the street, a box made of wood (often home-made), plastic or metal (ready-made) is placed in the hole, and it is also taken out near the stove. Usually, inlets are located in the area that is protected by a metal or asbestos sheet from coals and firebrands.

Ventilation openings in the foundation are provided at the planning stage. If the foundation is already ready, but there are no ventilation holes, you can make the floor ventilation in the steam room differently: lay the floor boards on the logs, but not close to each other, but with a gap of 0.5-1 cm. In the gap between the draft (earth / concrete) floor and the finishing floor, an outlet is arranged, which passes into a ventilation pipe that leads the exhaust air to the roof (but not to the attic). This option provides for the presence of only one inlet, which is usually arranged below the heater. The exhaust pipe under the floor is installed on the opposite side of the room (but not opposite, but obliquely).

It is impossible to make an exhaust pipe in a steam room from plastic boxes for ventilation - they cannot withstand high temperatures, but it is permissible to use them in a locker room or washing department.

With such a ventilation scheme in the steam room, cold air warms up near the stove, rises, then, cooling down, falls down, seeps through the cracks in the floor under the floor and is discharged through the outlet pipe. These two options effectively remove moisture after the bath, they can also be considered floor ventilation schemes in the bath.


Exhaust openings can be located on the opposite wall from the supply opening (if both of these walls face the street) or on the same wall, but in the opposite corner. There is a scheme in which they are located at the top on the opposite wall (30 cm from the ceiling), sometimes they are located below (30 cm from the floor). If the exhaust vent is at the bottom or on the same wall as the inlet vent, a fan is needed to create airflow.

In order for the ventilation in the bath to remain effective, it is impossible:

  • make ventilation vents smaller than calculated ones;
  • to place the supply and exhaust openings one opposite the other - so the incoming air is almost immediately removed without giving up oxygen, a draft is formed, which is contraindicated for a bath.

Steam room ventilation schemes

Consider some of the most common options for ventilation in the steam room:


These are the most commonly used ventilation schemes for steam rooms in the bath, there are many more variations and combinations. Based on these four options for organizing ventilation, you can develop a scheme for your steam room.

Ventilation in the washing section of the bath

In the washing room, high humidity is a common thing, and so that the lining does not rot or an unpleasant smell appears, it is necessary to provide floor ventilation. It is arranged similarly to floor ventilation in a steam room: an exhaust hole is made between the rough and finishing floor, which can be equipped with a fan. The exhaust pipe is displayed on the roof.

With such a floor ventilation scheme in the washing compartment, the coldest exhaust air is removed, and warmer air from the upper layers descends in its place. Thus, an increase in the comfort of the people living here is also achieved.


The principle of the ventilation device in all other rooms of the bath is the same. You need to decide on the optimal ventilation system specifically for your conditions and select / develop the most suitable scheme. The ventilation in the washing department differs only in that, due to lower air temperatures, plastic ventilation ducts can be used here (which cannot be done in the steam room) and fans can be installed not heat-resistant, but only tolerant of high humidity (moisture-proof).

Brick and Turkish bath ventilation

When planning a ventilation system for a brick bath, it must be taken into account that its efficiency should be several times higher than that of a wooden one. Indeed, in this case, it will be necessary to dry not only inner lining steam/washing/changing rooms, but also walls: brick is a very hygroscopic material. To remove all moisture, it is necessary that the inflow / outflow of air during drying be very active, and the vents should have reliable dampers that allow you to adjust the intensity of air movement.

When arranging ventilation with its 100% humidity, exhaust ventilation must also be very efficient: in an hour of operation, it is necessary to provide six changes of air in the room. In addition, it is necessary to provide for the possibility of removing condensate, which forms during cooling in large quantities. There are two ways to solve this problem: install an air dryer in the pipe, which discharges condensate into the sewer system, or provide a channel for condensate drainage in the ventilation pipe (it also goes into the sewer).

Output: it is necessary to plan ventilation at the design stage of the bath, placing supply vents in the foundation. If necessary, you can make vents in the finished walls, but this is quite troublesome and difficult.

Bath procedures are not only one of good ways maintain hygiene, but also the ability to remove accumulated harmful substances and toxins. However, in order for the visit to be comfortable and beneficial, a good one is needed to exclude the possibility of the formation of fungi and mold due to high humidity. Ventilation in the bath, equipped by specialists or with your own hands, will ensure the flow of fresh air into the room and remove exhaust gases and fumes resulting from the operation of the heater and the use of hot water.

Read in the article

Do you really need ventilation in the bath or can you do without it?

The functions of bath ventilation are complicated by the fact that it should contribute to a fairly rapid removal of moist air from the premises and qualitatively regulate the temperature in the steam room. It is especially important to have a good exhaust system for baths equipped with gas and solid fuels - to maintain the combustion process in such structures, an influx of an impressive amount of air is required. Lack of ventilation will lead to excessive concentration of carbon dioxide, which adversely affects the health of people and which can lead to loss of consciousness.


Inexperienced craftsmen try to carefully isolate the premises, sealing up the slightest gaps to increase the speed of heating the steam room and keep the heat longer. However, this is the wrong approach, since ventilation holes must be mandatory. Properly arranged allows you to:

  • create a healthy microclimate in the bath;
  • reduce the concentration of humidity and quickly drain the premises;
  • get rid of carbon dioxide;
  • quickly warm up the steam room and other bath rooms;
  • eliminate stagnant and unpleasant odors;
  • get rid of pathogenic fungi and mold;
  • save in original form interior decoration premises.

From the foregoing, it becomes clear how important the device is in the exhaust system bath. Before you make ventilation in the bath, you must first learn about its varieties and basic installation schemes.

Effective ventilation in the bath - scheme and device

Before further dealing with the exhaust system and proceeding with its arrangement, you should know that ventilation can be natural and forced. There are also differences in ventilation systems and their schemes depending on the location. Well, now about everything in order.

natural ventilation

This option is optimal for most baths, as it is the cheapest and quite effective. The location of the ventilation openings must be determined based on the size of the room, the location of the heater and shelves, as well as the material from which the sauna is built. Whatever the ventilation schemes in the baths, there is one general rule- the supply opening should be located at a height of 20-30 cm from the floor level, and the exhaust at the same distance, but from the ceiling.


The dimensions of the vents should be approximately 300-400 mm 2. If the air exchange is too fast, which will cause a decrease in the temperature in the steam room, the ventilation openings must be covered with special control dampers. For improvement appearance it is desirable to mount on vents decorative lattices, which can be easily bought in specialized stores or made by hand.

However, this type of ventilation is not suitable for a steam room. All ventilation openings (inlet and outlet) must be at the same level from the floor. Thus, the incoming air streams are heated from the furnace and rise up, while the cooled air flows down and enter the exhaust vents. To keep the heat in the room, the openings can be closed with special dampers.

Forced ventilation

Mechanical movement of air is carried out by installing special devices on the ventilation openings (). This will allow you to quickly update the air, which is very important, especially in the washing room. This ventilation option is well suited in cases where it is installed in the bath. The forced exhaust scheme in the bath has a number of advantages over the natural one:

  • it is possible to filter incoming air masses;
  • maintaining a given microclimate;
  • even distribution of heated air.

For large volumes of fresh air to enter the steam room, it is necessary that the ventilation openings are located diametrically to each other. During installation, it is not necessary to place the inlet and exhaust vents at the same level in order to exclude the closure of air flows, which will cause a concentration of cooled air below, and on the contrary, it will be very hot at the top.

Important! Because high humidity and heat are the main enemies of any electrical equipment, then the fan case must have reliable moisture protection, and the connection must be made in full accordance with the PUE.

The advantage of forced-type ventilation is accelerated air exchange and advanced adjustment options. Such an exhaust system is equally effective regardless of the strength and direction of the wind, as well as weather conditions.

The device in the baths of floor ventilation

The floors in the bath rooms are operated in extreme conditions. The impact of moisture on the floor is carried out both from below from the side of the soil, and from above. The most difficult conditions are created in the steam room, where hot steam comes into contact with wooden coating floor, cooling and condensing. The resulting condensate penetrates into and creates a favorable environment for the development of fungus and mold.


Efficient scheme floor ventilation helps prevent the destructive effects of mold and remove excess steam. Floor ventilation can be natural or forced. However, for efficiency when installing a ventilation system, the following conditions must be observed:

  • prevent floor cooling during the adoption of procedures;
  • ensure fast and efficient drying, but it is important not to overdo it in order to prevent cracking of the wood;
  • the arrangement of the ventilation system is required to be carried out at the construction stage.

When arranging ventilation vents, it is necessary to take into account the climate, wind conditions, landscape, sources of pollution, as well as internal factors - the type and location of the heater, the design of doorways, the presence of vents. Most often, vents for ventilation are located at 3 different levels:

  • under the floor covering or in;
  • under the heating structure or at the level of its foundation;
  • in the wall at a distance of 350-450 mm. from the floor level (best done behind the heater).

The device in the ventilation baths under the floors has a number of advantages. In addition to eliminating condensate and improving the quality of drying the floor covering, the air flow from below does not form drafts and, therefore, ventilation can also be used in the process of taking bath procedures. For greater efficiency, it is important to correctly create a drain system to remove drains outside the building.

Creating air exchange in the foundation of the bath

The creation of an exhaust system in the bath is extremely necessary, as it not only helps to prevent the formation of mold, but also to protect the building from rot. The characteristics of the ventilation system are calculated at the design stage. The type and location of bath ventilation largely depends on the prevailing winds, topography and the presence of water bodies, which often cause buildings to flood.


It is possible to ensure normal air circulation by arranging several holes, the number and size of which are calculated in accordance with the size of the bath. The diameter of the vents must be at least 110 mm. Ventilation openings are usually made opposite each other. In the event that the building is located in a lowland, is densely surrounded by other buildings, or there are natural barriers to the free movement of air flows, then vents must be arranged on all sides of the foundation, since this is the only way to achieve high-quality ventilation.

The ventilation system in the baths in the steam rooms

Traditionally, a stove-heater is installed in the steam room, which forms the basis. The air from the steam room passes through the blower, which ensures its good circulation. To obtain the maximum outflow of air masses, the stove should be installed below the level of the finished floor, and to start the process of ventilation of the room, it is enough to slightly open the window or front door. The disadvantage of such a ventilation scheme in the steam rooms of the baths is that when there is no combustion process, the air circulation stops.


In addition to the heater, ventilation in the steam room is provided by additional openings with special dampers to regulate air exchange. After each bath procedure, you should open it for a while, otherwise the air in the room will be heavy and humid, and there is also a risk of carbon monoxide poisoning.

When the furnace is being heated and the room is being heated, the ventilation in the steam room must be closed. After the steam room is fully warmed up, the exhaust dampers can be opened. To exclude the formation of reverse thrust, it is necessary at the stage to make sure that the exhaust openings are larger in area than the supply openings.


In the event that the stove is not installed in the steam room itself, then a different ventilation scheme is used in steam Russian baths. Near at a height of 300 mm. an inlet is made from the floor level, and an exhaust opening is arranged on the opposite wall from it at a distance of 300 mm. from the ceiling. Sometimes an inlet is made at the bottom of the wall behind the stove so that the air coming from the street is heated from the heater and the room cools moderately. On the wall opposite from the heating device, 2 holes are made that will form a single exhaust duct. The first opening is located at a height of 1,000 mm. from the floor level, and the other under the ceiling. With this ventilation scheme, the steam room warms up faster and, accordingly, fuel is saved.

Air exchange device in the washing

In the washing room, as well as in the steam room, there is high humidity, which contributes to the appearance of mold and fungi. To avoid this, it is necessary to create an effective ventilation system in washing baths. In the washing room, a large amount of moisture accumulates under the floor, so to remove it, it will be enough to lay an asbestos pipe, one end of which is under the floor covering, and the other is brought out to the roof and equipped with a deflector.


Efficient controlled ventilation in bathhouses will ensure dryness, moderate temperature, fresh air supply, carbon monoxide removal and fuel economy in the premises.

Scheme of ventilation in the dressing rooms

The neighborhood of the dressing room with the steam room leads to the fact that on wooden surfaces condensate settles. To preserve the cladding and prevent decay processes, the room must be well insulated and drafts excluded. Most simple circuit ventilation for the dressing room consists in the removal of moist air through the washing or. It is best to organize a forced-type ventilation system for this room.

How to properly ventilate the bath

Having more or less dealt with the ventilation system in the bath, you must also take into account other important points. The exhaust device must not:

  • cause a breach temperature regime indoors;
  • allow cold air to rise to the ceiling;
  • remove fresh air from the room.

The principles by which proper ventilation of the premises is created in the bathhouse depend on architectural features building structures. In the event that special slots are provided in the floors for water drainage, then fresh air can flow through them and there is no need to make additional exhaust openings.

Often they make small windows, which, when opened, act as a hood. In addition, if the furnace of the heater is located directly in the steam room, then ventilation is even easier - it is enough to open the combustion chamber and, by changing the position of the damper, regulate the air exchange. These are the simplest, but most effective and low-cost options for installing a ventilation system.

Features of air exchange in frame baths

If in or air circulation is carried out through the rows of lower rims, then in frame-type buildings, sheathed with a large number thermal insulation material, there is no natural ventilation and for this reason it is necessary to provide for the creation of special openings with dampers.


most efficient system for the bath is supply and exhaust ventilation. To organize high-quality air exchange, it is necessary to create two channels. One of them is located near the floor and serves to bring fresh air into the room (if necessary, you can install a fan), and the second is arranged at a short distance from the ceiling and is necessary to remove hot and humid air masses and carbon monoxide. Ventilation openings in frame baths should be equipped with special control dampers.

When creating a ventilation system, it is necessary to take into account the area and shape of the steam room, as well as the location of the heater.

Chopped bath ventilation

In the Russian bath, where steam was traditionally prepared by hand, forced air circulation schemes are not suitable. To in wooden baths natural ventilation contributed to recovery, when creating it, the following schemes should be followed:

  • ensure the possibility of ventilation (creation of windows, door and ventilation openings);
  • the upper borders of doors and windows should be at the same level;
  • for steam rooms of a small size, simple ventilation is sufficient;
  • a heater with a chimney is a natural exhaust of exhaust air and gases;
  • for normal air exchange, it is possible to equip a ventilation supply opening with a damper and an exhaust opening under the ceiling next to the heater.

The device for good ventilation in a log cabin is very important point, since it is necessary to exclude the accumulation of excessive moisture, which adversely affects wooden structure and can lead to the development of pathogenic fungi and mold.

Ventilation system in a brick building

About the arrangement of ventilation in brick baths should be considered at the construction stage. Since a brick building does not provide for the presence natural circulation air, then the number and location of openings should be taken into account in advance.

The air exchange system in a natural way is identical to that in a Russian bath - the inlet is located next to the stove, and the exhaust is under the ceiling. However, if the bath is designed for a large number of people, then you should think about creating a forced ventilation system.


The fan must be installed at the inlet of the exhaust duct leading to. To speed up air circulation, several exhaust pipes are mounted, but it may be necessary to install supply valves so that the air masses are not discharged due to the difference in the volumes of supply and exhaust air. Too much powerful fan can lead to the same problem, and a device in terms of power that does not correspond to the area of ​​\u200b\u200bthe room will not be able to perform its functions normally and the air exchange in the steam room will be rather weak.

Ventilation Bastu

IN Lately new and more efficient solutions are found for creating ventilation systems. Such innovations include the ventilation scheme in the Bastu bath. Among Russians, this system is very popular because of the ease of installation and high efficiency.


The principle of ventilation according to Bast is as follows. The red-hot heater acts as a heat pump and draws air from the supply duct. Cold streams, passing through, heat up very quickly and rise to the ceiling. Naturally, they push an equal volume of near-floor air through the exhaust duct. In the Bastu ventilation system, the supply and exhaust openings are located at the bottom.

For the device of such ventilation, two stainless pipes are required - the lower one is installed diagonally from the heater at a height of 200 mm. from the floor, and the top above the stove. Both outlets must be equipped with damper grilles. However, like all natural-type ventilation systems, Bastu can only work when the stove is running or when there is strong wind outside.

The main advantage of the Bastu ventilation installed in Russian baths is the ease of installation, which you can do yourself, thereby saving your money.

Competent ventilation device in the bath

Normal ventilation can be only if the conditions for the inflow of fresh air and the removal of exhaust air are created in the room. Despite the common concepts - ventilation is not entirely true, since it is always supply and exhaust. The principles of operation of ventilation for any premises are almost the same - fresh air enters through the supply opening and is removed through the exhaust.


When calculating ventilation systems, it is necessary to take into account the volume and purpose of the premises, the presence or likelihood of the formation of carbon monoxide or other chemical compounds harmful to health. Regulations set the frequency of air exchange for an hour, which can fluctuate 1-10 times or more. Next, the parameters and location of future air ducts are determined, taking into account the climatic zones and weather conditions characteristic of the area. In the event that natural-type ventilation is not able to provide the necessary air exchange rate, then forced-type systems are used.

Where to place a window in the bath?

Windows in the bath are not only a source of light, but also a way to ventilate it. There is an erroneous opinion that the window in the steam room adversely affects the safety of steam in the room and the temperature. However, experienced attendants are advised to make even two windows in the steam room. One window is located above the shelves, and if the steam turned out to be too hot or someone felt unwell, then just open the window and everything will be in order. The second window is placed under the shelves, which allows you to quickly dry the sun loungers. It is made small and opaque.


Important! According to safety regulations, sauna windows should open inward.

It is also worth installing a window in the washing room. It will not only help to ventilate the room, but also to urgently evacuate in case of fire. The dimensions of the window should be such that a medium-sized adult can climb through it. Some bath owners are interested in the question: is it possible to install? If in the washing room, then yes. However, in a steam room, where the temperature reaches one hundred and above, the material from which the windows are made will begin to release toxic substances and warp. For windows in the steam room, it is best to use wood that is not resinous. You can easily install a window in a bath with your own hands, since the technology is no different from installing it in a residential building.

On a note! Bath windows for greater heat retention are best done with double glazing and good sealing.

Fan in the air exchange system of the bath

To create a high-quality forced ventilation system, you will need the following parts:

  • duct box;
  • and lattice;
  • damper;
  • fan;
  • grid;

Grate made of wood or heat-resistant plastic and metal grid prevent insects and domestic insects from entering the premises. A corrugated hose or a galvanized pipe is usually used as an air duct. Experts do not recommend installing in a steam room plastic pipes because they are not designed to operate at high temperatures.

It is advisable to install the fan only on one, for example, on the supply air. Fans used for baths must be made of heat-resistant materials and have good sealing.

A video on how to make a fan with your own hands will more clearly show the process (a bladeless version is presented):

ventilation valves

The ventilation valve for the bath is mounted in the supply and exhaust ducts. There are two types of this device - KIV (air infiltration valve) and KPV (forced ventilation valve). Outwardly, they practically do not differ from each other, and the principle of their work is the same. The outer part of the damper is equipped with inclined shutters to prevent water from entering from the outside, and the inner part is equipped with a head and membranes for sound and heat insulation.


When installing valves, you should follow a few recommendations:

  • for bath ventilation it is necessary to install dampers made of heat-resistant materials;
  • installation must be done on load-bearing walls baths;
  • it is not advisable to mount the valves on the walls facing the or trash can.

Vents in the baths

Vents, or as they are also called, vents, can be round, rectangular or square. They are located at the base of the building and on the roof. In the baths, the products are located at a distance of 2 meters from each other, and if there are holes in the basement, then holes are made in them. In these elementary ventilation ducts it is also necessary to install gratings to protect against rodents.


The video shows how to make an vent in the bath

How to make an extract in the bath

Do-it-yourself exhaust device in the bath is a simple matter, but nevertheless, it must be approached with the calculation and slowly. First of all, you need to decide on the scheme, the choice of appropriate materials and calculate the diameter. The volume of supply air must be equal to or less than the volume of air removed. To comply with this condition, it is necessary to know the volume of the room and the frequency of air exchange. The air speed in the main line should be no more than 5 m/s, in the steam room - 2 m/s, in the branches - 3 m/s and natural ventilation - 1 m/s. In the table, you can find the most suitable pipe diameter for obtaining the desired air volume at the specified flow rate.



Now knowing the diameter, it remains to take the appropriate pipe or corrugation and fix one end in the room, and bring the other out. For fixing, self-tapping screws, metallized adhesive tape and mounting foam are used. A damper is placed at the inlet, and a grate at the outlet. Ventilation ducts should be cleaned at least once a year.

Being indoors, a person absorbs oxygen, exhaling carbon dioxide. Everything seems to be as usual, but if such a room means a steam room, where hot steam is constantly swirling, then fresh air in this case has nowhere to come from. In such a room it is impossible not only to rest, but even just to be. After all, the body gradually relaxes, the amount of oxygen, in turn, decreases, and by the time there is nothing to breathe, a person may simply not reach the door.

According to safety standards, the replacement of air in the steam room should occur many times a day so that the people who are there can relax and cleanse themselves. Otherwise, a person will not be able to restore strength and will return home tired, with migraines and oxygen starvation. That is why the bath needs to be equipped proper ventilation, because what can cope with the microclimate better than her? Neither herbs nor various incense will be able to add a couple of "usefulness" if there is no air circulation.

So, today we will talk about how ventilation is provided in the steam room with your own hands.

Improperly equipped ventilation can lead to certain consequences.

  1. Even with good ventilation, the tree is subjected to enormous loads, so it often lasts no more than twenty years. Without fresh air, the service life will be reduced several times.
  2. If carbon dioxide is not removed from the steam room, then its use will do more harm than good. In addition to carbon dioxide, combustion products accumulate there, and fungi and mold are permanent “guests” of any room with insufficient ventilation.
  3. If the steam room is not ventilated, then soon it will be filled with the smell of rotten wood and stale air.

Another important function of air circulation is heat transfer. The point is that the air high humidity does not conduct heat well and as a result, the stove will only heat the space around it. That is why the ventilation inlet is usually located behind the stove, almost above the floor itself. This contributes to the fact that already heated air is distributed through the steam room; if the ventilation inlet is located elsewhere, it will supply cold air into the room, thereby disrupting heat transfer.

The exit must be installed on the opposite side of the entrance.

Note! A common mistake is often encountered: the entrance and exit are placed on the same level. This creates a vicious cycle that barely affects most of the room. As a result, it will be too cold below, and too hot under the ceiling.

When arranging a bath, it is important not only right choice any ventilation scheme. Of great importance is the diameter of the ventilation holes. It is calculated as follows: for every 24 cm of the hole there should be one cubic meter of the room, otherwise there will be no circulation.

It should be noted that it is desirable to equip the inlets and outlets with plugs to regulate the intensity of air exchange. Mines should be laid even during the construction of the bath.

Bath ventilation methods - which is better?

The steam room can be ventilated both by natural air movement and artificially, using a specially installed fan. Artificial ventilation is rightfully considered simpler, because it is possible to properly equip the entrance / exit only with special knowledge and considerable experience.


Note! Not every duct fan is suitable for providing artificial air ventilation. The installed model must tolerate high humidity and temperature changes well, otherwise the electronics will break, which is extremely dangerous in a conventional wooden structure, which is often a Russian bath.

The technology of arranging ventilation in the steam room

To begin with, we note that the air flow primarily depends on the furnace. So it's worth finding out how it works.

Where does the ventilation of the bath begin?

It is worth noting that the firebox can be located both in the steam room itself and in next room. Brick or stone is used for lining the furnace. A 5 cm gap is required between the lining and the metal.

Often, a firebox is installed in the rest room - so the garbage will not accumulate, and you will not have to run to the steam room every time in order to throw firewood. And now - directly to work.

First step. Forced ventilation

A special channel is equipped for it, located above the floor. The channel should be located near the firebox where a metal sheet is laid that protects the tree from coal.

Step one. First you need to build a special box, which would be about 1/5 more than the chimney. The box is displayed outside, and not under the floor, otherwise unpleasant odors will constantly hover in the steam room.

Note! When the firebox is located directly in the steam room, two boxes are needed at once - the second will be convection.

Step two. Next, you need to equip a special podium near the wall, in which holes are made for air flow. For this, three rows of bricks are laid out with an “edge” - one under the wall, the second in the middle, and the third at the edge.

Step three. Masonry is being made for a furnace 25 cm high up to the very brick screen, in the upper part of it (masonry) must be blocked. In place of the immediate location of the furnace, you do not need to put the last two bricks - so fresh air will go into the furnace itself. The end must be laid with a brick.

Step four. The convection box must be brought to the end. A blower is installed on its end. It is necessary to put something under it, otherwise it will constantly rub against the floor when opening / closing etc.

Step four. After the construction of the podium, you can install the oven. It's better to do it on special metal corners, which will evenly distribute the load on the box. It remains only to overlay the oven and install a screen with several holes. These holes will be ventilation, which will allow you to warm the room with hot air.

Second phase. Outflow ventilation

We have already considered the construction technology of the main heat pump. It remains only to take care of the outflow of air. Perfect option- install the outflow box diagonally with respect to the inlet, which will allow you to ventilate the steam room as efficiently as possible.

Step one. If the brick shirt of one of the walls goes, for example, into the rest room, then you just need to bring out another door there. So you can kill two birds with one stone: take the air out of the steam room and heat the dressing room (of course, if the box is installed correctly).

Step two. Box construction. This box must be made with an area of ​​​​125 cm² (+ 10%) and installed approximately 30 cm above the floor surface. Further ventilation duct should go through the wall to the ceiling and out into the street.

Note! For the construction of the structure, you can use ready-made ventilation ducts, sheathing them with clapboard after assembly. So the products will look more natural, not differing from the general background.

About heating and ventilation

If the lower doors are open during the operation of the furnace, then the air, penetrating through them, warms up and leaves the room through the upper ones (but not completely - some of it drops and heats up again). The lower door should be opened even before the oven is melted in order to ensure its “acceleration”.

At the same time, the steam room will heat up until the hot air reaches the bottom of the box, after which it will begin to squeeze out cooler air, which, in turn, comes out and heats everything that comes in its way. This is how the steam room is ventilated and heated at the same time, and this is how proper ventilation should function.

Note! The convection doors open every time someone is in the steam room. These doors, being connected to neighboring rooms, warm them up.

As a conclusion

Few people know that when insulating a chimney in a bath, they deprive themselves of another source of heat. Of course, you should not leave a red-hot chimney in a “bare” form, you need to make a brick casing around it, building a blower door on the second row. And if you equip a second door on top, then a real heat pump will come out, which will both warm up and ventilate the room.

A well-equipped ventilation system, other things being equal, guarantees, firstly, a long service life of building and finishing materials involved in the arrangement of the serviced premises, and secondly, the comfort and safety of visiting the latter for the user. Particularly relevant is the issue of arranging full and sufficiently effective ventilation in the bath, due to the characteristic temperature and humidity conditions and additional requirements for such buildings.

The choice of the optimal type of ventilation system for servicing a bath is a topic for many hours of discussion. For example, there is natural ventilation. The cost of money, time and effort for its arrangement is minimal - the work literally comes down to drilling holes in the walls, installing boxes / pipes and valves / gratings.

However, it is impossible to use natural ventilation to serve all the premises of the bath. Of course, it would be possible to save money, but the disadvantage of such a solution will become obvious with the arrival of the first winter: along with the influx of fresh air from the street, cold will come in, and everyone knows the combination of frosty air with humidity - everything around will simply freeze. Therefore, natural ventilation in some rooms must be combined with others. existing options in other bath rooms.

If the bath is equipped with a washing room or even a private pool, natural ventilation will definitely not cope with the maintenance of such premises - you will have to equip exhaust system. And in general, the presence of a forced inflow / outflow of fresh air will be useful for both visitors to the bathhouse and its premises. Recommendations for optimal composition air exchange system are shown in the table.

Table. The choice of ventilation system for different rooms

roomRecommended type of ventilationSchemeDescription
Steam room, dressing room or rest room Under aeration it is necessary to understand the organized natural air exchange. The option is most optimally suited for use in a bathhouse: air is supplied from the bottom of the stove (for other rooms - 25-30 cm above the floor), exhaust air is removed through an opening in the upper part of the room. The work of air exchange is based on elementary physical laws: cold air from the street displaces warm air masses, which have less weight, up the room.
Aeration is ideal for use in rooms with high heat dissipation rates. The presence of additional moisture contributes to an even more pronounced increase in the efficiency of the system.
Wash room, bathroom, pool room The system is equipped with a fan and, if necessary, cleaning filters.
Mechanical exhaust ventilation is ideal for use in the washroom, pool room and other damp and high traffic areas of the bath. A mechanical extractor effectively removes unpleasant odors and excess moisture, which makes the air in the serviced room safe and clean. It is impossible to use only exhaust ventilation - air rarefaction is formed. To compensate for the rarefaction, air is supplied from the street or other rooms.
Along with this, the presence of forced ventilation will eliminate the likelihood of drafts.
The supply ventilation system can be either natural or mechanical. In combination with mechanical exhaust ventilation, it is more expedient to use a mechanical supply system, because. the potential for natural inflow may ultimately be insufficient to compensate for the resulting rarefaction.
At the heart of mechanical supply ventilation is a blower fan. Additionally, it can be equipped with an air heater, which will eliminate the inconvenience and solve the problems of ventilation of the serviced premises during the cold season. Additionally, the supplied air can be humidified or purified using appropriate devices.
The mechanical system is more complex in arrangement compared to its analog, which works according to the laws of physics: in addition to fans and air ducts, the system may include additional equipment and devices (diffusers, air distribution grilles, automation equipment, silencers, etc.). This gives an excellent opportunity to arrange an air exchange system that fully meets the wishes of the user.

In vestibules, warehouses and other premises of a similar purpose, a natural hood is made.

Regardless of the type of ventilation system chosen, the bath must have conditions for simple ventilation. Install adjustable windows in all rooms, the location of which allows this.

Instructions for self-calculation of air exchange

For the calculation, an elementary formula is used:

W (required volume of fresh / exhaust air) \u003d k (coefficient indicating the frequency of air exchange) x V (volume of the serviced room, determined by multiplying the width of the room by the length and height).

That is, first you must calculate the volume of each room and find the required volume indicator for it. clean air(in calculations it is customary to denote Wpr, i.e. inflow) and a similar indicator of exhaust air (indicated as Wvt, outflow). In this case, multiplicity factors must be taken into account. The calculated values ​​are rounded up - the last digit in the number must be 0 or 5.

Next, the summation of all Wpr is performed. A similar action is carried out for the found Wvt. The amounts received are compared. If the total value of Wpr exceeds the total indicator Wpr, it is necessary to increase the exhaust volume for rooms with a minimum air exchange value, if vice versa, increase the inflow by the missing value. That is, at the output, the sum of all Wpr should be equal to the total value of the found Wvt.

The results of the calculations will allow you to determine the optimal cross-sections of the installed air ducts and choose the appropriate type of ventilation system. Thus, with the calculation of the volume of premises and other related data, there will be no particular problems. For greater convenience of subsequent processing, enter the found values ​​in a simple table, as in the example presented.

In the given example, the total value of Wpr is less than the sum of all found Wvt by an indicator equal to 110 m3. In order for the balance to be maintained as a result, it is necessary to ensure the flow of clean air in the missing amount. This can only be done in the waiting room. Thus, the value of 55 m3 for the dressing room, given in the table, must be replaced with an indicator of 165 m3. Then the balance will be struck.

Proceed to the calculation of the installed air ducts and the drawing up of the structure of the equipped ventilation system.

The ventilation system is designed in such a way that the air moves through the installed air ducts with the following speed indicators:

  • ≤ 5 m/s in main channels and ≤3 m/s in existing branches - for mechanical ventilation systems;
  • ≤ 1 m/s - for air exchanges operating according to the natural principle;
  • 2 m/s - for natural air exchange directly in the steam room.

When choosing the cross-section of air ducts, consider the above indicators. As for the profile of the box / pipe, this moment is determined by the design features of the air exchange and the bath itself. For example, air ducts with a circular cross section are easier to install than their rectangular counterparts, and it is much easier to select the required connecting fittings for round air ducts.

The relationship between the diameter of the air ducts and other significant indicators is shown in the following tables.

For example, we will work with round ducts. We select the necessary sections according to the corresponding table, focusing, at the same time, on the indicators of the table An example of calculating ventilation.

Estimated air consumption is 165 m3/hour. The air flow at this flow rate should not move faster than 5 m/s. In accordance with the table above for round ducts, we select the section according to the specified data. The tabular value closest to ours is 221 m3/h. Air duct cross section - 125 mm.

Air duct with insulation
Flexible ducts

In the same order, we determine the optimal sections for all branches of the system in the serviced premises, remembering that in them the air flow should move at a speed not exceeding 3 m / s (in vestibules and closets - 1 m / s, in the steam room - 2 m / s). sec):

  • steam room: calculated Ww is 60 m3 / h, which requires the installation of an air duct with a cross section of 125 mm;
  • shower room - Ww is 50 m3 / h, air moves at a speed of 3 m / s, a 100 mm air duct is suitable;
  • toilet - the indicators are similar to the shower room;
  • pantry, vestibule, etc. - indicators (except for the speed of air movement) are similar to the shower and toilet.

Important! In the shower room (washing room, room with a pool), an increased level of humidity is noted. When determining the cross-section of the duct for this room, it is necessary to make an upward correction (in this example- 125 mm).

For greater convenience, enter all the information received in the table. As an example, you can use the template below.

Important note! In the table above, the extract volume exceeds the clean air supply. This happened because the sections were determined by the nearest flow rate, and the diameter of the air duct in the washing room was deliberately increased. In practice, such an approach will only benefit - the margin for outflow and inflow will not be superfluous.

The cross-sectional area of ​​​​the ventilation window is determined in accordance with the volume of the served room: 24 cm 2 for every 1 m3.

It remains only to deal with optimal height vent locations:

  • for the influx of fresh air - an average of 25-30 cm above the floor (in the steam room - near the stove);
  • for the outflow of exhaust air - about 15-20 cm below the ceiling, as a rule, on the wall opposite to the supply air.

Popular bath ventilation schemes

Separate consideration deserves only options for arranging ventilation in the steam room - in other rooms everything is done according to standard scheme, for example, like this:

Air exchange in the steam room can be organized in accordance with 4 main schemes presented in the following image.

Scheme "a". The most popular option. The window for air flow is next to the stove, at a distance of about 25-30 cm from the floor. The incoming clean air gradually displaces the exhausted warm upwards to the opposite wall. On it, about 15-25 cm below the ceiling, there is an exhaust hole.

Scheme "b". Both holes are on the same wall. The circuit will only work if an exhaust fan is installed. Fresh air enters through the lower opening, equipped in the wall opposite to the stove. The air will rush in the direction of the stove, and then, covering the space of the steam room with an arc, move to the hood and be discharged outside the bath.

Scheme "in". The option is suitable for steam rooms with a leaking floor. The inlet opening is located as in scheme "a". After warming up in the upper part of the steam room, the air descends to the floor, passes through the gaps in the boardwalk, contributing to more efficient drying of the boards, and then is removed through the exhaust hole, usually equipped in another room. Also, the hood can be carried out through a separate insulated channel.

Scheme "g". Option for baths with a constantly working stove. In this case, the function of the hood is performed by the blower hole of the furnace. The supply window is arranged under the shelf, in the wall opposite to the furnace. The height of the inlet must correspond to the height of the furnace blower. Fresh air rushes to the stove, displacing the air masses heated by it to the ceiling. Cooling down there, the air descends and is removed from the bath through the blower.

In order for the operation of the air exchange system to be as efficient and high-quality as possible, before starting its installation, study and remember a few simple tips.

If your bath has a bathroom or even a kitchen, equip them only with exhaust ventilation - this solution will eliminate the possibility of unpleasant odors spreading to other rooms. Alternatively, you can equip other rooms with forced ventilation, and equip the bathrooms with a natural exhaust - in this case, the air will move towards the bathrooms.

When calculating the performance of fans, it is recommended to reduce the total capacity of the supply units by 5-10% of the total performance of the exhaust units. In this case, the exhaust air will be completely displaced by the incoming air masses, and a 5-10% reserve will compensate for the inflow of air entering through windows, slots, etc., which will allow you to maintain a balance.

In rooms with only natural ventilation, it is recommended to definitely make opening windows - this will increase the efficiency of fresh air intake and reduce the risk of fungi, mold, rot, etc.

Important! If your bath has a non-standard configuration, the ventilation system project will also be individual. When compiling it, the features of the composition of the premises, their design, design features etc.

The main stages of independent arrangement of the ventilation system

Any ventilation system in any room is equipped in approximately the same sequence. Differences are present only in the characteristics of the air vents and their locations, as well as the configuration of the system (mechanical, unlike natural ones, are supplemented different kind devices).

For example, the following arrangement of ventilation elements can be used.

Or its somewhat modified counterpart, shown in the following image.

Recommendations regarding the choice of the location of each opening, the type of air exchange system for different rooms of the bath, as well as the procedure for determining the characteristics of the ventilation elements, were considered earlier.

Along with this, the procedure for arranging ventilation may vary depending on which design option you prefer. There are few solutions available:

  • independent ventilation in each room. An easier option. Work is limited to the installation of transoms, vents, fans and other necessary elements, if provided for by the project. Fans can be mounted both in windows and in separate channels brought outside through the wall;
  • centralized system. More difficult option. Requires ventilation ducts. It is used mainly in private homes - in the case of a bath, this option will be too costly and time-consuming;
  • "hybrid" option. Some rooms are ventilated individually, some are combined into a joint system.

A reasonable option for use in a bath is independent ventilation - the owner can choose the optimal characteristics of fans and other elements for each room, saving money, time and effort on the activities necessary to combine the channels into a single system.

Important! The location of some bath rooms may not allow to equip independent supply and exhaust ventilation. In this case, it will not be possible to avoid laying ventilation ducts. Alternatively, the boxes can be placed in the attic, and the ventilation holes can be arranged in the ceiling or connected to the channels equipped in the walls (the option is more complicated if the laying of such channels was not provided for by the project at the construction stage of the bath).

In most cases, the first option is used: ventilation pipes of the required length are led out through openings in the ceilings of the serviced premises and either equipped with their own fan, if necessary (easier to implement for an unprepared user, the procedure is similar to that given in the following table), or connected into a single circuit and connected to a common hood (may require the involvement of specialists).

Remember: the maximum efficiency of the ventilation system is ensured by using as short and straight air ducts as possible - up to 3 m with natural air exchange and up to 6 m with electric fans.



The procedure for arranging an independent ventilation system is given in the following table.

Important! The example considers instructions for arranging a mechanical ventilation system using fans. The order of installation of natural air exchange remains almost the same: only the stages of laying wires and installing fans are excluded.

Table. Arrangement of ventilation

Stage of workExplanations

The operating procedure remains the same for the supply and exhaust openings. Only the height of their arrangement and location changes ( possible options discussed earlier), as well as the type of fans used (supply or exhaust). The characteristics of the latter are selected on an individual basis, taking into account the volume of the serviced premises, the required air velocity in the air ducts, the required air exchange rate, etc. - all these moments were consecrated in the theoretical part.
We equip the holes in the following order:
- we outline the center and contours. We make the markup so that the diameter of the hole as a result slightly (usually a 2-3 mm gap is made) exceeds the diameter of the installed pipe (recommendations for choosing the diameters of the ducts were given earlier);
- Using a perforator, make a hole in accordance with the markings. We hold the working tool horizontally, but with a slight downward slope;
- carefully take out the cut material (a hammer and a chisel will help us with this), after which we carefully clean the finished hole from dirt and dust.

The ventilation pipe (ventilation duct housing) is placed in the prepared hole, but before that it (if mechanical / forced ventilation is planned) must be equipped with a fan.
Useful recommendation! Initially, buy ready-made kits for arranging ventilation, including, in addition to related accessories, a ventilation duct / pipe and a fan with an appropriately sized case - this way you will avoid difficulties during the assembly phase.
The pipe with the fan is placed in the prepared hole, and the remaining gaps are filled with mounting foam.

fan is electrical appliance, therefore, it must be connected to the network. Let's do this while the mounting foam dries (at least 10-12 hours).
The procedure is standard:
- the contours of the strobe for the cable are cut out in the wall using a grinder. Excess material is removed using a chipper;
- a hole is prepared in the wall for installing the switch box (for example, you can use a puncher). The box is installed (pre-read the instructions specifically for your switch). The switch itself will be mounted after finishing;
- the wire is laid in a strobe. We use alabaster to fix the cable;
- connect the wire to the switch and fan. We must first study the connection diagram recommended by the fan manufacturer in the attached instructions, because. it may differ for different devices. For example, one of the most commonly used schemes is given.

It remains only to bring the whole structure into its proper form. To do this, we do the following:
- get rid of excess dried polyurethane foam with a knife;
- putty strobes;
- we mount adjustable ventilation grilles on both sides of the pipe. For fastening we use self-tapping screws.
If provided, we install additional elements at the appropriate stages of work (for example, an air heater, a filter, etc.). Each of these devices is mounted individually - we first clarify these points in the manufacturer's instructions.

Baths have always been famous for their healing properties. But in order to obtain a healing effect, it is necessary not only to listen to the advice of doctors, but also to organize the correct ventilation system in your own bath.

Those who have been in the classic rustic baths made of wood are unlikely to remember the presence in such paired exhaust vents. In fact, they are not there. After all, a small amount of fresh air entering the bath from cracks in the floor, window or doorway can meet the needs of 2-3 people.

But a bath, designed for a large capacity, and even more so brick, in without fail should be arranged ventilation system to do the following important things:

  • fresh air intake, which prevents the accumulation of carbon dioxide in the steam room and preserves the health of people in the bath;
  • air circulation, which allows you to dry the room after bath procedures. This prevents the appearance of unpleasant odors in the bath, the growth of mold fungi and helps to increase the life of the building without the need to replace wood elements;
  • uniform distribution of heated air in the steam room of the bath.

Moreover, if the hood is arranged correctly, it should not lead to the following unpleasant consequences:

  • to a drop in temperature in the steam room during bath procedures;
  • violation of the correct stratification of air by temperature - the coolest layer should be at the bottom;
  • removal from the steam room of clean air, and not saturated with carbon dioxide.

It is easy to breathe in a well-ventilated steam room, and it is pleasant to relax

How is bath ventilation

It is correct to provide for the bath ventilation system even at the construction stage, because it is at this moment that you can make the hood correctly and independently with the lowest labor and material costs. In addition, the process of making holes in finished construction can lead to a decrease in the strength of the walls.

Air exchange in a bath is provided by means of two openings.

  1. The supply opening is located at the bottom and provides fresh air to the bath.
  2. The exhaust opening is located at the top on the wall opposite the supply opening. Thanks to the exhaust, the exhaust air is removed from the steam room. However, if the opening is located very close to the ceiling, then hot air is quickly removed from the room, which leads to a decrease in the temperature of the steam room.

This design allows you to adjust the direction of the air flow. At the moment when the bath is heated, all three holes are in a closed state. When people are steaming, the supply and lower exhaust openings are open. After bath procedures, all ventilation is in the open state, which allows you to dry the bath well.

Ventilation in the bath can be mechanical. In it, the air in the steam room circulates thanks to the injection equipment. In a more complex and expensive version, special devices monitor the air supply process, which, if necessary, start the ventilation system. The use of a mechanical hood allows you to place holes on any of the walls, as well as correct errors in the organization of natural ventilation.

In any case, to ensure air exchange in the bath, there are several exhaust schemes that differ from each other in the location of the holes.

Methods for ventilation in the bath

Let's describe some of the most popular and simple ways of arranging ventilation in a steam room. They can be either with the use of fans, or carried out in a completely natural way.

Method 1

This is the one described above natural ventilation scheme with one inlet and two outlets. The inlet in such a system is made in the wall immediately behind the stove at a distance of 0.3 m from the floor surface.

To connect the outlets to each other, a box is used, which is made of wooden planks, they lay in it corrugated pipe about one meter long. The holes themselves are provided with plugs that allow you to adjust the air flow, as described above. In addition to the plugs, you will also need gratings to prevent insects and rodents from entering the bath through ventilation.

This system is applicable for small baths.

Method 2

This is another simple and most common scheme for ventilating the bath space. In it, the supply hole is located behind the stove just above the floor (about 0.3 m). The hood is located at the same height, but on the opposite wall and is equipped with a fan that forcibly draws out the exhaust air.

Method 3

Method 3 is somewhat similar to the previous one. Only the air inlet is arranged at a height of half a meter from the heater, and the outlet is just above the floor (about 0.2 m). The hood is equipped with a fan.

Method 4

Method 4 is used for baths in which the steam room has only one wall facing the street. In this system, air inlet and outlet openings are located on the same wall opposite the stove. Air enters into the lower hole, located at a height of 30 cm from the floor, and exits into the upper one, which is located 30 cm below the ceiling and is equipped with a fan.

Clean air enters the room, collides with the stove, heats up, rises and is directed through the outlet to the outside.

Method 5

Method 5 is suitable for baths in which there are small gaps of half a centimeter between the floor boards. The inlet is located behind the stove. The cooled and exhausted air descends to the floor and exits through the cracks in the underground, where there is an exhaust hole in the basement wall, connected to ventilation pipe, which removes air flows above the roof.

Method 6

If in your steam room the stove is heated for the entire period of the bath, then the blower can itself perform the function of ventilation, or rather, the hood. In this case, only an air inlet is needed, which is located near the floor opposite the stove. The blower should be slightly lower than the finished floor.

Step-by-step instructions for installing ventilation

When arranging a bath with ventilation, it is important to observe the following conditions:

  • if the bath is adjacent to a residential building, then the air flow should go in the direction from the housing to the steam room;
  • the exhaust hole is connected to a box or pipe, which is necessarily brought out above the roof of the bath;
  • the hood should not be done over the shelves in order to exclude the effects of a draft on steamed people.

In general, the ventilation installation process can be described as follows.

Step 1

In selected places, at the construction stage, or prepare after construction, inlet and outlet openings, the cross section of which should be 10-20 cm.

Step 2

Prepared holes are equipped with boxes made of metal, plastic or wood.

Step 3

Install an exhaust fan if necessary.

Note! For baths, it is necessary to use ventilation equipment made of heat-resistant material and with a protection class of at least IP-44.

Step 4

Mounted on grille holes and plugs.

Step 5

The outlet is connected to a pipe, which is led out above the roof.

Note! In addition to ventilation of the room, it is necessary to ensure air circulation under the floor. To do this, at the construction stage, holes are made in the basement on opposite sides, which are covered with gratings to protect against rodents.

In such simple ways, you can arrange bath ventilation, ensuring a long service life of the steam room and a comfortable stay in it.
