Since you are building your floor-level shower yourself, you can let your creativity run wild in the next step, because then the tiles are attached. Here, colors and shapes have no limits. However, you should be careful that you do not reduce the slope of the floor tiles. After the floor tiles, attach the wall tiles. These are now on the floor tiles, which prevents water deposits in this area. After the tile adhesive has dried, grout the wall-floor joint with the special sanitary sealant or jointing silicone. The remaining joints close as a last step. So you can simply build your floor-level shower yourself!
