We have done several tile showers over the years. We thought that we would show a few examples for you in a series of blog posts. Hopefully, these will give you some ideas for your tile shower.
There are lots of options in a tile shower other than tile size and color. The main ones to think about are (1) the size and location of niches in the walls for things like shampoo and soap, (2) the size and locations of seats, and (3) the entrance into the shower, which could be a door or a curtain or a glass block wall.
