Do-it-yourself hole in a cast-iron bath

Sooner or later, most people want to do something in the bathroom with their own hands.

Most often, we are talking about installing hydromassage equipment or simply transferring the mixer to the side.

Both in the first and in the second case, you will need to drill cast iron bath. If the hand is not stuffed, then complications such as chipping of the enamel, slipping of the tool from the right point, or a banal scrapping of the drill may occur. Drilling is required to be done slowly, because. the material you are working with is also quite brittle.

Hole drilling

You will need:

• permanent thick marker;
• drill for metal;
• drill;
• kerosene solution;
• grinder (optional).

The first step is to clearly mark the place of drilling with a thick marker. The mark is set small so that when drilling it does not deviate much to the side.

Many people cannot distinguish a cast-iron bathtub from the rest. If you don’t go into details, then it is many times heavier, and if you can’t lift it in flight, then this is cast iron. In order to drill a bathtub with high quality, it is important to be very careful, because. the enamel is quite fragile, respectively, and it is quite easy to damage it. From the very beginning of drilling until completion, for this reason, the drill / brace should be held at one angle.

The drill must be perfectly sharpened, and it is necessary to be very clear on the drill itself, which will be exclusively for metal and with an angle of 116-118 degrees. It should just stick into the metal, but not scratch it. Insufficient sharpening can crack the enamel, as well as retract the tool and ruin the material. In order to drill a cast-iron bath evenly, you can use wooden board or a metal plate, where there will already be a finished hole of a slightly larger diameter. A small difference in diameter will not give any side effect, but it will guide the drill perfectly.

Cooling the drill is neglected by many beginners, but using a kerosene solution can greatly help speed up the work. In addition, if the drill does not overheat when working too often, then it will wear out more slowly, this will also allow them to drill more holes, i.e. increase tool life.

One of the secrets of how professionals manage not to damage the enamel around the hole is to use grinder. They simply remove the enamel in the desired area and capture a diameter of 2 mm, which provides an excellent opportunity for risk-free work.

During repairs, builders may face the problem of drilling cast iron bath to install a faucet, sink or for other purposes. Cast iron itself is drilled, as a rule, without problems, but how can you avoid chipping the enamel?

Instructions on how to drill a cast iron bath

In order to drill a cast-iron bath you will need
- drill;
- diamond drill or crown;
- drill for metal;
- rubber nozzle with abrasive rings;
- grinder;
- sealant or epoxy adhesive;
- water;
- conductor.

Using a marker, mark the drilling point on the enamel layer. To prevent the drill from slipping, scratch the point with an awl or the end of the drill.

To drill through the enamel layer, use a diamond drill. Drill very slowly, constantly cooling the drilling site with water, not allowing it to heat up. In order to cool the drilling point, stretch a tube supplying water to it, while being very careful, do not forget that you have a power tool in your hands.

After drilling through the enamel, change the drill bit for a regular drill bit for metal. If a small hole is needed, drill a small diameter hole first and then ream it with thicker drills. Do not forget to cool the metal and drill slowly, if it heats up and “whitening” occurs on the surface - the drill will become dull already at the first millimeter, as the cast iron will become harder than hardened steel.

If you need a large diameter hole, make a jig out of a piece of plywood with a center hole. First, drill through the jig to remove the layer of enamel with a pen drill on glass or tile. Then remove the jig and drill with a regular metal drill. Please note that the holes in the conductor should be located at a distance of no more than 1 mm, then the disc will be removed easily. Bore the hole from the inside with a rubber nozzle with abrasive sandpaper rings.

If you have a grinder, try drilling as follows: use it to grind off the enamel along the contour, then drill along the contour with a small drill and shape the edge with the same grinder.

If, nevertheless, part of the enamel is chipped, close the edges of the hole with a decorative chrome cup of the appropriate diameter.

When you drill a hole in a cast iron bath, cover the surface of the exposed cast iron with sealant or epoxy glue, otherwise rusty stains will begin to appear on the enamel after installing the faucet.

The modern interior of a bathroom of any size involves not only the rational placement of all necessary elements, but also makes high demands on the combination of their style, comfort and functionality. Therefore, the installation of a faucet on the side of the bath is becoming increasingly popular. The faucet installed on board the bathtub looks elegant and original, which brings zest to the bathroom interior.

Advantages of mortise-type faucets on the side of the bath

The operational task of this type of in-line faucet is to create a strong, stable flow of water for accurate filling of the tub.

The mixer is installed on the side of the bath

Installing a faucet on a bathtub has the following advantages:

• ensures quick and accurate filling of the bath;
• prevents splashing of water;
• optimizes bathroom space;
• provides ease of use;
• allows you to disguise the hose of the shower head.

Cascade mixer creates a jet like a waterfall

A bathroom with a built-in faucet becomes stylish and as comfortable as possible. Especially interesting are the cascading models, reminiscent of a small waterfall.

Important: Due to the wider diameter of the spout, the load on the design of the mixer increases, and the hose located under the bathtub wears out faster than usual. Therefore, when choosing a faucet on board the bathtub, special attention should be paid to its strength and durability.

In the previous article, we considered the issue - now we will talk about the features of the installation.

Stages and features of installation

An experienced master will install a mortise mixer on board the bath in a couple of hours. For a non-professional who decides to do such work on his own, it will take much more time. To begin with, you will have to study the mortise-type mixer device, since its installation is somewhat different from installing a traditional design.

Advice: If possible, to facilitate the task, it is recommended to immediately purchase a bathtub with a hole for the mixer.

To complete the work you will need:

• electric drill with a nozzle in the form of a crown cutter of the desired diameter;
• adjustable wrench, screwdriver;
• flexible hoses;
• fasteners.

How to drill a hole in an acrylic bathtub

How to drill a steel tub

Important: The hole on the edge of the bathtub can only be made independently if it is made of acrylic or similar composite materials. Cast iron and steel bathtubs should only be processed at the factory to avoid chipping of the enamel, which will lead to corrosion. But you can take a risk if everything is done very carefully.

Many manufacturers of faucets for installation on the side of the bathtub have special mounting plates as an addition to them. Their use makes it possible to strengthen the attachment point, since when creating a hole, the rigidity of the bath rim is significantly reduced.

In practice, masters prefer to do without these additional panels. Often they do not fit in size and require trimming. It is also difficult to use them on a rounded side. At the same time, one should not forget about the functional purpose mounting panels. Therefore, if there is any doubt that, with a decrease in rigidity, the rim of the bathtub will withstand the load, you need to consult with specialists.

Faucet in the side of the bath - to take or not to take?

The main thing is to approach wisely both the choice and the installation of the mixer on board the bathtub. And then this decision will be the most correct.
