My daughter is just finishing up a bathroom remodel and used a porcelain tile that has the look of marble. I have posted these pictures on a couple of other threads but here they are again for your viewing pleasure. The tile is Daltile's Florentine Carrara. It is available in several sizes and in a matte or shiny finish. Here countertop is not in yet so can't show you it installed but you can see a sample of it in the last picture.

The walls are not as dark as they look in the photo
