Curves feel more welcoming than sharp angles in a tight space, and this unique teardrop-shaped sink is both a space saver and a focal point. The curved shower wall in this wet bath echoes the lines of the sink, creating a smooth and seamless look. With a smaller scale than most sinks out there, a single-basin, single-handle, gooseneck faucet sink can fit into even the tightest spots. And it looks pretty swell doing it. The designers of this space-conscious houseboat chose a sliding door to save room. The swing of a traditional door can eat up a lot of floor space; go with a pocket door or sliding barn door instead and save that precious square footage for other things.
