I like this idea for small bath; Our bathroom is a bit wider and the sink is on the other wall, but with a tall glass door closet and drawers under the sink, this layout could work.
Amazing built-in nook with glass lantern providing reading light. Reading nook with gray ikat fabric cushions and pillows as well as white roman shades covering windows. Second landing nook with built-in reading lounge and built-in shelving.
