This could work in a tiny bathroom. Love the tiled floor/painted wall combo and the fact that the tiles in the shower match the wall colour but are different from the floor. The niche for storage works well for us too.
Natural light is a major mood booster, not to mention a major selling point in any home. The warm kiss of sunlight indoors will make your space feel bigger, cozier, and way more put together than any dimly lit fluorescent light bulb ever could.
