I'm recommending repainting the floors a sand color, and the walls and ceilings a beachy blue; specifically Yolo Colorhouse Water .03.

A larger mirror above the sink will help bounce more light around the room.
Ideally, I'd also like to add a backsplash for a punch of color, but that may not be in the budget.

Actually, I'd like the bathing cap photo up high on the larger mirror with Hello Beautiful painted over the lower portion. A little positive reinforcement never hurts.

Sometimes simple designs are the best.
