Although it offers less comfort to its users, the shower has many more advantages than the bathtub. Not only does it save space in the bathroom, but it also uses less water and heating than a bathtub. So many reasons that push us to favor it and sometimes even consider it instead of the bathtub… So, without further ado, let’s dive into this blog and learn some of the things you need to know before replacing a bathtub by a shower.

1. The location of the new shower


To avoid plumbing work, the easiest way is to install your new shower in place of the old bathtub. This way, you can use the existing water and drain lines. In order to choose the location of the shower, it is important to know that the shower tray must be at the same level as the floor. For this reason, in some cases where it is necessary to overcome the difference in level, it is necessary to raise the floor or install a step to access the shower.

2. Water supply and drainage

Whatever the model of your shower, the water drainage system is attached to its trap. To ensure proper drainage of wastewater, the drain must be located a few centimeters below the floor level. In other words, you must create a minimum slope of 1% between the trap and the drainage system. And if you can’t arrange the drainage system properly, you can always opt for a lift pump whose purpose is to redirect the water.

3. A good seal


To avoid the risk of leaks, you must be extra careful when installing the shower and ensure a good seal. Remember to provide sealing strips at the corners and sides, but also at the bottom of the cavity, using sealing tapes around the thread of the mixer fittings, not forgetting the seals at the siphon. It is also possible to apply waterproof paint around the shower tray or even resin! In any case, it is best to consult an expert to find out which solutions are best suited to your configuration.

4. Wall coverings

When you remove your bathtub, your wall may not have any covering. So, you need to think ahead and choose the type of wall covering you want for your future bathroom layout. Not only will you have to cover this newly exposed area, but for visual harmony, you may have to change everything. Tile is still the best option for the bathroom and is relatively easy to install. But nothing prevents you from choosing wall panels to dress up the empty space or opting for a shower model with wall panels.

5. Faucets

This is the last big step in installing your new shower. After wrapping sealing tape (counter-clockwise) around the threads of the mixing valve fittings, you can screw the fittings on and attach them to the water supply. Attach the thermostatic valve, connect the shower hose between the shower head and the mixer, and now you just have to take care of the finishing touches, such as the shower rod or the walls.
