Frequently Asked Questions

What shower niches is this compatible with?

The shelf is designed to fit shower niches with an inside width of 12 inches (before tiling). It’s compatible with prefab niches from Kerdi Board SN (12×12, 12×20, 12×28), Wedi (12×12, 12×18, 12×26, 12×38), and Houseables Shower Niche.

Can I install this in an existing shower?

No, the Redblock Shower Niche Shelf is installed during the tile installation process and is not suitable for retrofitting into an existing finished shower niche.

Can I install the Redblock niche shelf with the rb3m logo facing down?

Yes. The RB3 logo is on only one side, but the finish is the same on both sides; so it can be flipped so long as you keep the washcloth hanger in front.

Why do you use 316L stainless steel?

We use a “Marine Grade” steel because sea Salt (sodium chloride) and Chlorine corrode steel in the same way. And since chlorine bleach is used extensively in shower cleaning and disinfection products, it seemed appropriate and responsible to be the first shower shelf company to use a Marine grade steel for our shower niche shelves. But we go one step further and use a special grade of low-carbon 316 (the “L” in 316L) which further enhances it’s corrosion resistance.
