We installed a 12x12 ceramic tile for the outside waynes
coat about four feet high and capped it off with chair-rail border. We used the same 12x12 and turned it on
a diagonal for the upper half of the shower walls. We installed a 18x18 on a diagonal with a listalla insert as
a border giving it a look as a throw rug. We built a nitch in the shower walls and fabricated a corner shelf made out
of a piece of travertine stone. We did the same application on the outside wall using a travertine as a shelf.
