love the dark gray with the white subway tiles, especially with the pops of yellow! MRC-- I don't necessarily like that dark of a wall color or the yellow but I like the big mirror that has a little contrast to the pedestal sink.
This is one of my all time favorite bathrooms (in the book Blue.) It is a blue and white modern interpretation of a Moroccan bathroom. I love everything about it from the river stone floors to the details and blue tiles.
