Have you noticed that the selection in tiles has come a long way in the past 5 years. The basic 12 x 12 and 18 x 18 square tiles are disappearing in favor of more interesting sizes like 12 x 24, 4 x 12 or 16 x 24 shaped tiles. The good news is that ceramic tile, much more inferior to porcelain tile, is also not so popular.
But one of the drawbacks to the new porcelain tiles is that they are not being imported with the matching surface caps or bullnose pieces. This is a drawback for inexperienced tile setters and designers.
There are 3 solutions to this problem. The first solution is to use a neat grout v-joint where the tile meets the wall. This solution is the least expensive one and looks very nice.
The second solution is to have your tile setter fabricate a half-bullnose edge on the tiles that edge your installation. This costs a bit more but looks very professional.
The third solution, as pictured above, is to have granite or marble edging fabricated from your vanity top leftovers. This is the most expensive solution, but as you can see, looks very beautiful and helps to tie all aspects of the bath design together. In this picture, Absolute Black granite was used to make 4″ wide bands with a Straight Polish on both sides. These trim pieces can also help disguise the fact one of the walls in this installation was not vertical, leaving a growing thinset line as the tile was installed. Since the granite pieces are 3/4″ thick, you can easily hide an “out of square” problem wall.
An experienced tile setter/fabricator can help you with either choice you make for your own bath remodel.
