You renovate your bathroom, only to realize too late that you haven’t accounted for sufficient storage in the shower. Or you’ve inherited an existing shower that has exactly one modestly sized niche that will never be big enough to store all your necessary bottles. You might think you’re doomed to a life with one of those clunky metal “caddies,” but what you really need is more shelving. And there are two pretty easy approaches you can take that don’t require much expertise or all that much work. Here’s how to add a corner shelf to an existing shower.

The Schluter SHELF-E

If you’ve ever researched bathroom renovations, you’ve probably come across the Schluter company, which makes a range of shower-related waterproofing systems and accessories. They also offer high-quality stainless steel shelves for the shower. While some of these shelves are designed to be installed during a renovation (typically with supports hidden behind the tile, their SHELF-E series of corner shelves are designed with tabs that are inserted into the grout lines. That means they’re easy to retrofit into an existing shower. Here’s what you’ll need:

• As many shelves as you need or want (they come in a wide variety of styles and shapes)
• A grout saw (either manual or a multitool blade)
• 100% silicone caulk (clear or tinted depending on your shower’s design and your preference)
• A caulk gun

The project is pretty simple:

1. Hold the shelf up to your grout line and mark where the tabs will sit.
2. Use your grout saw to cut out the grout where the tabs will insert. Because these are small cuts, it’s easy enough to do this with a manual grout saw.
3. Tape the tile and fill the gaps you’ve cut with silicone caulk.
4. Fit the shelf into place. The tabs will hold it securely.
5. Fill the gaps with caulk—both top and bottom. If the shelf sags slightly, add a support.
6. Smooth caulking and remove tape.

That’s it—once the silicone sets up, you’re done, and your shelves are ready to use.

The glue job

If you’re not comfortable cutting the grout lines for the Schluter shelves, you can glue a corner shower shelf into place in about half an hour without compromising the integrity of the grout or tile. One caveat here is to not buy a “self-adhesive” shelf that purports to just stick on your wall out of the box. While that is probably fine for a short-term solution, it will likely eventually fall off the wall. …….
