We're thinking this could be a pretty cool idea for a loft space, inspired by this 1954 bathroom. Get some trellis sections available at a hardware store, paint them a bright color, and hang them strategically to create separate areas. If you're really handy, you could mount them on a track to create Japanese-esque sliding doors.
