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.
Love the use of copper that looks like pennies in this bathroom. (Hmm copper pennies are a very inexpensive floor!) Goes very well with the long slabs of stone tile. Open shower and giant soaker tub beautiful and easy to clean
