Review on Maximize Bathroom And Kitchen Storage With Hoomtaook Wall-Mounted Corner Caddy: 2-Tier Adhesive Triangle Shelves With No Drilling Required! by Ryan Hoover

Out of the box the shelves will not work for rounded corners. Most shelves won't, but these can be hacked easily. Just bend down the corner using a pair of pliers. Hold the shelf up to the wall above your shower insert (where the corner is 90 degrees) and that will show how far in you need to bend the corner.I used the sticker installation. Big tip: only peel off one sticker at a time and be sure the screw posts are more centered. The instructions booklet has pictures for reference of where the screws should go. Don't ignore this or you won't be able to get your shelf back off.
