I wanted a shelf that wouldn't take up too much space, like many of these do. This fit my space perfectly. The only thing I didn't account for, was the lack of space behind the toilet: see the pic with the bottom part circled in red. That piece of the shelf, which is for stability and absolutely needed for this structure- had no way of fitting/sliding down in behind the toilet, even if i took off the tank lid. So, I built the shelf without it, stood it up over the toilet, then installed that one remaining bar while the shelf was standing up in place. Overall a minor annoyance, but if you're physically limited as far as putting things together, you might need someone to help you with this, if it doesn't easily slide down behind your toilet.
