We’ve seen small bathroom solutions before. So far, though, I don’t think anything will let you equip a small bathroom as creatively as the Vertebrae, which puts all your private hygiene necessities in a single swiveling file.
Created by Design Odyssey Ltd., the veritable Swiss Army bathroom puts every modern bathroom amenity in a single line of stacked rotating modules.  That way, only the module you need will take any extra space, leaving you with the whole room to practice your ninja skills while taking a shower.
The Vertebrae consists of seven modules stacked on top of the other and anchored to a pole. The only fixed one is the toilet in the bottom, which you can access by moving the modules right above it out of the way. Aside from the actual bowl, it comes with two access doors on each side, where the toilet papers and toilet brush are stored.
A full-featured sink gets the second level, while the third and fourth are occupied by storage bins (where you can keep your soap and toiletries and such).  The pair of topmost modules are both showers, allowing for up to two persons to get cleaned up at the same time. Water for the bowl and showers is collected in a tank that acts as the fourth module, where a mirror is also attached.
According to the product brochure, water can be fed through a hole in the ceiling, with pipes hidden inside the hollow steel pole.  Waste pipes can be directed through a hole in the floor directly below the loo.
In all seriousness, the Vertebrae is possibly the most clever bathroom fixture I’ve ever seen. I’d throw it in my house right now, if only the $10,000 base price wasn’t a little out of my league.
