Not sure how useful this will be to others, but as a Practical Cut I wanted to share 
If you have this (or a like one) over-the-toilet storage shelf, do I have the shelf liners for you!
(right click to save!)
It takes a Pro or 2 separate cuts, but it’s tight enough that you need to put the ends in and then lower the center down to get it to fit - and then it’s locked in against the uprights.
It makes the shelves about 3" longer because they no longer cut in on the sides - and flat so your stuff doesn’t roll off at the slightest provocation Made out of clear acrylic it’s surprisingly stealthy!
At least on mine the top shelf is sized slightly differently, but since I keep towels up there I didn’t put a liner on it. This worked on both the center and bottom shelf.
On that last shot, despite what it looks like!) there’s less than 1/8" difference between the wire shelf and the bottom of the acrylic - the acrylic rests on the cross bar.
Enjoy!
