This could work in a tiny bathroom. Love the tiled floor/painted wall combo and the fact that the tiles in the shower match the wall colour but are different from the floor. The niche for storage works well for us too.
Every color appears splendid with white marble. Other people may think that you can't use this color for the bathroom but after seeing the pictures above, I'm certain that you've changed your head about it.
Designer Mark Williams - Larger 9 x 18 Carrara marble tiles surround the window while smaller marble subway tiles line the arch. To complete the traditional look, Mark chose Cararra marble and black granite basketweave tiles for the bathroom's floor.
