When you’re tiling your shower, it’s important to choose the right kind of tile. There are many factors to consider, of course.
Porcelain tile is generally a better choice, since the finish is smoother, and it is more water-resistant. It’s also easier to clean. It’s also better to use smaller tiles in the shower, since they offer better slip resistance than larger tile. The tile also needs to be secured to the backer, not merely glued on in sheets. A shower wall should be sturdy and not easily permeated by water.
