For a simple look - Large white tiles - Kerry Phelan Design. Similar layout of our small bathroom with a floating sink! Would prefer a glossier finish to the tiles since we won't be tiling all the walls "wet room.
White hexagonal bathroom floor tile with white border separated with black stick detail, and white subway tile on the walls with white cove base and mudcap? with black stick between. And white above that all the way up in the shower.
