A house we are considering as open tiled showers similar to this. The tile is brown (not gray) and it (thankfully) has no window right there at the shower! I love the idea of an open tiled shower! No glass to keep clean, no curtain driving you crazy!
I love the black and white with the patterned floor tile. The matte black fixtures are lovely. The circle mirror is cool juxtaposed with the modern angular sink. Always a fan of the white subway tiles.
