I purchased this to use as shown in the photo.  However, when I set this up, found that the wire first shelf was just forward enough to bump my head (or any guest's head) on.  Perhaps if the toilet sits out further from the wall, this wouldn't be an issue.
HOWEVER, I decided to see if I could use it in my office instead, and it works perfectly to hold some light items of my router, modem, and some small office things.  Ended up working out well for me, but not in the bathroom, as I'd hoped.  

Pros: Was easy to assemble, useful in my office
Cons: Bumped my head on it and it would have gotten bumped by guests using the toilet - not useful to use as shown in the picture, in my house.
