For a new shower build, your contractor will only need a grout removal tool and silicone caulking. For a retrofit installation in an existing shower, you'll need the above items plus a drill with a 3/32 inch bit.

Yes. The Redblock shower corner shelf is designed to fit into the grout lines of any type of shower wall tile, as long as the grout joint is 1/8 inch wide, and the joint depth is at least 1/4 inch, which is very common in most tile installations.

Based on Redblock's in-house load testing, both the small shelf (SCS-B) and large shelf (SCS-B-XL) were loaded to 30 lb with minimal visible deflection in the recorded test installations. Demonstration only; installed performance depends on tile assembly, grout-joint condition, and installation quality.

The shelf is made from marine-grade 316L stainless steel, one of the most corrosion-resistant steel alloys available, and routinely used in laboratories and ocean-going vessels. Still, no steel is completely rust proof. Cleaning with a non-abrasive soap and avoiding bleach-based cleaners is a good rule for all shower fixtures and accessories.

Consider shower size, reach height, bottle size, grout line location, and whether you're interested in a permanent in-grout shelf or OK with a temporary caddy, suction shelf, or pole organizer.

For a permanent tile shower, stainless steel is usually the better premium choice. Aside from its temporary look and often flimsy construction, plastic shelves have the benefit of being rust-proof, but they will discolor, become brittle, and crack over time.

An in-grout stainless steel shower shelf is one of the best options because it installs in the grout line between the tile, so the tile is left untouched. Many corner shelf options involve screw holes through the tile surface which can easily chip and crack the tile.

Yes. Redblock's corner shelves can be retrofit installed into existing tiled showers by removing two small sections of grout, inserting the shelf into the notches, and applying a perimeter bead of silicone to secure it.

Use a mild detergent such as diluted dish soap and a soft cloth. Avoid abrasive pads and strong bleach-based cleaners, which can affect metal finishes and surrounding shower components.

No. The Redblock shelf is designed for in-grout installation, so it does not require screws through the waterproofing membrane.

Yes. New construction is one of the best times to install the shelf because the tile layout and shelf height can be planned beforehand.

Almost any DIY homeowner can complete a retrofit installation of the Redblock corner shelf by following the simple directions. You can also hire a qualified tile professional if you're hesitant about marking out tab locations, using a grout removal tool, or applying a clean bead of silicone.

Yes, natural stone (especially marble), matches particularly well with the brushed stainless finish because of the similar grey tones. Installation is exactly the same with stone tile as it is with other types of tile. You simply need a 1/8 inch wide grout line.

Choose the smaller shelf if you prefer your shelves to extend only 5.75 inches diagonally out from the corner. The XL shelf extends 7.5 inches diagonally out from the corner. Most people choose the small shelf for compact showers and guest bathrooms, and add more storage with multiple shelves. People generally choose the XL shelf for walk-in showers, family bathrooms, and for larger bottle storage.

Yes. Multiple shelves can be used in larger showers or compact showers that demand more storage. Smaller showers benefit from the lower profile of the SCS-B. You can add as many shelves as you prefer as long as there's a grout joint to install it into.

The shelf is installed with only silicone. Always follow Redblock's corner shelf installation instructions.

Yes. It gives contractors a durable, professional-looking shower storage option that avoids the common problems associated with temporary plastic caddies, adhesive shelves, and the waterproofing damage caused by screw-mounted accessories.

Install it at a comfortable reach height, usually away from direct body movement zones. In new construction, coordinate shelf height with the tile layout before setting tile so grout joints will line up in the corner at the correct height.
