To finish the framing procedure and improve the shower niche’s visual appeal, you must remove the portion of the wall that is beneath the niche. Nevertheless, because this process is so sensitive, you should exercise particular caution. Otherwise, you risk damaging the drywall on the wall’s opposite side.

Step 3: Waterproofing

Consider applying a thin coating of mortar with a thickness of about 14 inches to the base of your shower niche to make it watertight. To ensure that the shower drains effectively, you must ensure that it is suitably inclined outward.

You are free to choose any type of tile that suits your interests, but we advise going with something like composite marble. On various sides of your shower niche, you can expose the edges of the tiles.

Step 5: Add grout

After the tiles are installed, you may start grouting. You could want to use pre-sealed grout. Prior you applying it to the full shower niche, make sure to test it out on a small portion of your space so you can perfect your application technique. On all surfaces, though, you must make sure that the grout is correctly applied.
