The purpose of a shower niche?

A shower niche is a recessed area in the wall of a shower that is designed to hold shampoo, soap, and other shower supplies. The purpose of a shower niche is to provide a convenient storage area for these items and to keep them out of the way.

It can also be utilized as a space for a neat and fashionable decorative decor such as plant placement or if safe enough for gadgets, cell phones and more.

What materials are needed to waterproof a shower niche?

Materials that are needed to waterproof a shower niche are tile adhesive, grout, silicone sealant, and a waterproof membrane. The membrane should be applied to the back of the tile adhesive before the tile is installed.

The membrane such as a schluter kerdi, trugard and others; will help to prevent water from seeping behind the tile and causing damage to the wall. The silicone sealant should be applied to the grout lines to help keep water out.

How to apply the waterproofing material to the shower niche?

Waterproofing the shower niche is a critical step in ensuring that your shower remains leak-free. Here are the steps you need to take to apply the waterproofing material correctly:

  • Clean the shower niche thoroughly.
  • Apply a layer of waterproofing material to the niche.
  • Let the material dry completely.
  • Apply a second layer of waterproofing material.
  • Let the material dry completely.
  • Apply a sealant to the niche.

All of this can be done using a roller or through precision application.

How to seal the shower niche?

There are many ways to seal the shower niche, but the most common is to use caulk. First, remove all of the old caulk from the niche using a utility knife. Make sure the surface is clean and dry before applying the new caulk.

Apply the caulk to the niche and use a wet finger to smooth it out. Let the caulk dry for 24 hours before attempting to using the shower.

Installing a shower niche is a fairly easy process, but it is important to make sure that everything is done correctly in order to avoid any leaks. Here are the steps you need to take in order to install a shower niche:
