Window, simple sink, add a W/C and small storage for towels and soap and it's the perfect indoor/outdoor bathroom. Simple but beautiful small bathroom. Love the hidden walk in shower. Great for the boys!
A house we are considering as open tiled showers similar to this. The tile is brown (not gray) and it (thankfully) has no window right there at the shower! I love the idea of an open tiled shower! No glass to keep clean, no curtain driving you crazy!
