Organize It All 3-Tier Corner Spa Shower Caddy in Silver and Black

I bought this corner rack to put in my father's shower since he sits in a shower seat, and only had the grab bars in the shower to hold his shampoo, body wash, etc. I searched and searched for a simple shelf that would sit on the floor inside the shower, have enough shelf space, and not be too expensive...this fit my needs perfectly. It's a good height, and has more than ample shelf space for the things my father needs in the shower. I ordered two since I'd read a rating that someone's rusted, figuring the second one could be a spare since I didn't know if I would be able to find the same product later on. But, one of the two already had signs of rust on the bottom shelf when it arrived. I put that in one of our own bathrooms in a corner where it can stay dry and hold spare toilet paper and such. It works fine and looks good there. Only room for improvement that I can think of: Make it REALLY rust-proof!
