Tile Redi recessed shower shelves provide the perfect spot for your soap, shampoo, conditioner, razor, shaving cream, body scrub, body wash, and other personal care items, while also eliminating the need for bulky shower racks and soap dishes that take up space in your shower or bath. The Redi Niches can be installed in a shower, spa, steam room, by a bath tub, on a bathroom wall, or any place else where you desire a waterproof, attractive shelf space that can be tiled. Tile Redi shower shelves are water proof, leak proof, and mold and mildew resistant - and are designed to be recessed into your shower wall for a streamlined, clutter free look. From there, the marble, stone, porcelain, glass mosaic, or ceramic tile of your choice can be installed directly to the surface of the shower niches with a premium modified thinset mortar or an epoxy adhesive such as Redi Poxy. No additional waterproofing is necessary!
