This looks very similar to the layout of our guest bathroom - vanity, toilet and window are all in the same place. I love the shelves above the toilet, the pictures next to the window, and the little stool holding the towels!
Eureka! Master bath walls are already green, and I committed to a white vanity when I let Spouse build white shelving over the toilet. Beige-ish countertop, dark wood floors (we'll use wood-look tile): DONE!
