How to Install a Bathtub on Concrete Floor
Installing a new bathtub is an operation that requires a lot of attention and precision if you decide to do it yourself. After carefully choosing the tub that is suitable for our needs and the most suitable point of the bathroom for its placement, it will be necessary to remove the old tub and install the new one, making sure to connect in the best way all its functional parts.
Here are the main steps on how to install a bathtub on concrete floor
Removal of the old bathtub
Before installing the new bathtub, the old one must be disassembled . To avoid flooding it will be necessary first of all to close the water supply and to have a large basin to contain the residual water in the pipes which, during the operations, could come out.
To remove the old tank it will be necessary to cut the old adduction pipes , the overflow pipes and the drain, with the help of a saw suitable to cut the metals.
Depending on the material of which it is composed, the tank can also be removed after being crushed with the aid of a club.
This operation is possible, for example, for cast iron tanks ; in this case, however, you must protect yourself by wearing the appropriate protective glasses and noise-proof headphones.
Choice of the new bath
There are various types of bathtubs ; before buying one it is important to have clear ideas on which type of tank is within reach of the spaces that are available.
The main models are:
- Rectangular tanks
They are the most common and widespread ones as well as the most economical ones.
The dimensions vary from 1.4 to 1.8 meters in length and with only 2 widths of your choice, that is from 70 or 80 cm.
This type of tanks take up a lot of space and are therefore suitable for very large bathrooms. They are equipped with a wide range of toiletries and accessories.
- Circular tanks
Although extremely spectacular, these pools are certainly not among the most widespread but if we intend to design a large bathroom with considerable dimensions , then a beautiful round tub in the middle of the room would be the ideal protagonist around which to rotate the remaining furnishings.
DIY installation of the bathtub
Before installation : laying the tiles on the wall precedes the installation of the tank. Before proceeding, check that the part of the non-tiled wall exceeds the overall dimensions of the tub in height and width, so that the tub adheres to the plaster and not to the tiling.
Once the old bathtub has been dismantled, you can start to prepare the floor and the wall to accommodate the new one.
Both, in fact, must be made waterproof. For example, a tiled floor ensures good watertightness, while for the wall it is necessary to apply a primer and a product that ensures a watertight seal.
Subsequently, the dimensions of the tank should be shown on the wall as a guide for installation. At this point, we can start assembling the pool tools.
If this is equipped with feet , you will need to install them by starting the fixing holes of the supports present on the feet themselves, with the help of a drill, and then fix them with a screwdriver.
- We put the new piping (D) of adduction or connect the branches of the new pipes to the existing ones (I) so as to be ready for connection to the hoses already connected to the taps.
- We insert two wooden boards under the feet of the tub in order to better distribute the concentrated loads on a larger surface.
- Set the tank in position and adjust the level horizontally by intervening with the key on the feet.
- Now we connect the flexible pipes (D) to the piping and the exhaust pipe (G) to the siphon (H)and finally all the way to the existing branch on the drainage column.
It is important to remember that when the tank is installed against the walls it is difficult to make joints and connections. The faucets, the overflow and the siphon must first be installed and then the tank pushed into place.
The drain and the overflow
Drain in the bathtub
Assemble the drain and overflow unit (E) . If the filler type is used, the overflow must be connected before the siphon, whereas in the siphon type, the plastic pipe is connected to the siphon.
Insert the pipe in the hole of the tank (G) taking care to wrap the teflon tape around the threaded column.
From below we add the plastic gasket and tighten the fixing nut by pressing the filler on the mastic or on the gasket.
We connect the siphon of the tank to the drain pipe and the overflow pipe (E) to the relative hole of the tank.
Installation of the faucets for the bath
Once this is done, you can install the faucets of the tub with the hoses. If the taps are on the edge of the tank, it will be advisable to drill, using a hole saw, the point where the tap will be placed.
Bath tub faucets
If the faucets are single (A) then the assembly is the same as those for the sink. Insert the taps of the taps into the holes (B) provided for the tank, insert the gaskets and tighten the nuts by blocking them.
We connect the copper hoses to the floor lamps. The mixers are mounted similarly but almost all have the long seal to be placed under the taps.
The choice of the faucets or the mixer is completely subjective. The mixers are available with a shower system, either mounted on the mixer or hung on armrests fixed to the wall above the bath.
Renew the old bath
If the old steel tank is not to be thrown away, then we can renew it by cleaning the surface with damp rags of turpentine so as to eliminate traces of grease.
Then, we can paint the tank starting from the bottom upwards in a circular direction using a special two-component glaze.
For professional finishes it is necessary to contact specialized companies that carry out spray enamelling.
