Product Description

As shower remodel professionals, my brother & I were routinely installing shower shelf products that were poorly designed, poorly constructed, and made from substandard materials. So we decided to make our own shower shelf – a shower shelf that satisfied the needs of our customers – a shower shelf that literally checks all the boxes.

Unhappy about your bar soap slipping away, or simply turning to mush?

Your not alone. Most of our clients complain the most about two things: Their bar soap slipping off their shower shelves, OR it turns to mush in a pool of water. Fortunately, the rounded drainage slots on the rb3m niche shelf solves both problems.

Tired of the moldy soap scum buildup in the back corner of your niche shelf!

Since the Redblock rb3m niche shelf attaches only to the side wall of your niche, a 1/2 – 3/4 inch gap remains behind the shelf. This effectively eliminates soap scum buildup in the back corners of your niche shelf, AND makes it super easy to clean!

Worried about another rusty metal shower shelf!

The Redblock rb3m shelf is the only shower niche shelf made from super corrosion resistant, low carbon, 316L stainless steel. We’ve recognized the increased use of chlorinated shower cleaning products since the pandemic, and the effect of hard water on standard 304 Grade stainless steel. And since 316 Grade stainless steel is the standard for laboratory & marine environments, it only seemed natural that we also use it in our shower shelf products.

Stressed about installation?

Because of its 3mm thickness, the Redblock rb3m niche shelf easily fits into standard 1/8″ grout lines. A stark contrast to those clumsy 4mm shelves that force you to cut the side and back wall tiles because it won’t fit into the grout line… you know which ones I mean.

Concerned about shelf strength?

With the rb3 niche shelf, you can put your worries aside. It’s a super solid 3mm thick, and has been tested at 11 lbs, with less than 1mm deflection. That means it can handle whatever shampoo bottles and toiletries you might want to store on it… and then some.

Tired of the sharp edges and crude finish of most stainless steel shower shelves?

Redblock has created a new standard of shower shelf finishing: CNC chamfering. One the finest of steel fabrication/ finishing techniques, CNC tooling creates ultra smooth, burr-free edges on all shelf edges and cutouts. A level of refinement you won’t find in any other shower shelf on the market.

Upset that you can’t install mosaic tiles at the back of your niche?

The rb3m niche shelf attaches only to the side walls of your niche, so you don’t need to cut a slot into the back wall tiles to make room for the shelf (as with other bathroom niche shelves). That means you’re free to install the niche back wall tiles before installing your shelf, AND be as creative as you like with your tile selection.

Irked about damp and moldy washing puffs and washcloths?

When you’re finished showering, just hang up your washing puff, brush, cloth or loofah on one of the rb3m’s accessory hangers. What a treat to have a dry wash cloth or washing puff ready for your next shower!

    Q: Q: Can your shelf be installed in an existing tiled shower niche?

    A: No. Our shelf is designed to rest on the top edge of the side wall tiles of your shower niche (in the grout line). This can only be accomplished if it is installed during the tile installation stage of your shower niche installation. See our rb3 Shower Niche Shelf Install Guide for more info.

    Q: I read somewhere that you need to make sure that shower niche shelves slope outwards. How would I do this with the rb3 shelf?

    A: The only reason most shower niche shelves need to be sloped, is to ensure that water drains off the front edge. Since our shelf is slotted, water drains away so you can install it level without worrying about the water pooling problems associated with ordinary shower niche shelf installations.

    Q: Does your rb3 shelf come in any other finishes than Polished and brushed Stainless?

    A: At the moment our shelves only come in these two finishes, but we are planning to introduce a few other finishes soon. You can join our mailing list if you’d like to stay up to date with all our new product announcements.

    Q: Since the rb3 shelf is 2 1/2″ wide, and my niche is 3 1/2″, where do you recommend we install it? Is it better to place it at the back or near the front of the niche

    A: It’s totally up to you where you install it but we generally recommend that it be installed as close to the front of the niche as possible to maximize the storage area. The only extra advice we give is to avoid the shelf coming in contact with any metal tile edge trim because it may dull the shelf finish over time.
