I think my favorite "in-access" thing is at my work, and I like it because it's kind of subtle. Unless you actually use that bathroom, rather than look at it, you might not notice the problem.

The placement of the hand rail on the wall - which is correct - means they put the toilet paper holder on the wall below the bar. Which might be fine if the holder weren't so huge, and didn't open at the bottom.

In order to get a piece of toilet paper, a person sitting on the toilet must bend and stretch all the way forward and reach to the floor to get it. I am a former gymnast, and thus bendy, and even I have trouble reaching a sheet of toilet paper. For someone who can not do that bending, I have no idea how they're supposed to get at the paper.

So, you can use the bathroom just fine, but wiping yourself? You're out of luck.
