I've been struggling with our bathroom. We have but one, so I have only one plumbing infested room to worry about in the house. I settled on a 'Modern Day Japan' (you know: robots, hello kitty, neon, superflat) theme which has yet to materialize in any concrete way other than the chiyogami box.
But these people have found a theme and run with it.
The Lyndon Baines Johnson Memorial Downstairs Bathroom and Reading Room.
Sadly, they don't seem to have any photos of the actual bathroom, just the memorablilia.
Still...sounds awfully grand, dosen't it?
