I’ve lived here over a decade with no shelving in the shower, and I finally bought an organizer! This has been a huge quality of life upgrade, it’s great having everything off the floor within reach. The shelving was super easy to install and I feel dumb tolerating the situation for so long.
Eh, I had one that was white painted steel, but wasn’t coated on the inside at all.
It rusting hadn’t occurred to me until I went to remove it almost ten years later and the joints between sections just crumbled to bits.
Held up quite well considering. They’re pretty cheap and replaceable when/if it’s a problem.
