Your shower looks amazing! What a great solution for your shower; and even better that they match.
Kristofor used our 3/16” Life Floor Slate Tiles. This is what he had to say “This product looks great and fits in perfectly with my bathroom design. The tiles are much more comfortable than my old ceramic tile to stand on. They are easy to work with, and the adhesive back is especially easy to use. The entire installation only took about an hour.”
