Shower Caddy 6 Pack, Adhesive Shower Shelf Rack with Soap Holder, Large Capacity Bathroom Organizers and Storage, No Drilling Wall-Mounted Bathroom & Kitchen Storage

My recommendation will apply to this brand as well as any other of these sorts of products; use only the long shelves because they have multiple connection points so are sturdy. The smaller ones are supposed to balance on one connection point so are wobbly. (You could use them elsewhere on a wall for something else if you used two screws to hold them level.) Keeping bottles off the shower floor really keeps it cleaner longer! No sitting water or soap means you don't have to clean very often. So glad we got these!
