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.
Mark my words it will get scuzzy but it doesn’t matter the storage space is totally worth it. Use a foaming cleaner and something like a general purpose toilet brush type thing and get that joker clean every once in awhile.
