Now, this is definitely a small bathroom -- but the shower's ingenious curved glass doors fold inward to sit almost flush with the walls, opening up the space more than we'd have thought possible. These sorts of folding shower walls appear to be more common in Europe than in the States. We found angular versions of these shower screens from Duravit and from Kermi.
If you're curious, you can see a video of the doors' swinging action on YouTube. Just don't blame us for the accompanying music.
The fact that it's a curbless shower opens up the space even more, but it also multiplies the water-damage risks. We'd be curious to know whether any of our readers have had experience with a bathroom like this. (You can respond in the comments or on the Yahoo! Homes Facebook page, or you can email us.) We've read that if the floor slopes properly toward the drain, the area will dry quickly.
And by the way: Installation of a wet room like this, especially with a curbless shower, probably ought to be overseen by a licensed professional.
