Package includes: (1) Tile Redi 16″ W x 6″ H x 4″ D Single Niche and (1) 6 lb set of Redi Poxy Epoxy Adhesive Tile Setting Material. The Tile Redi RN166S-BI 16″ W x 6″ H x 4″ D Single Redi Niche makes manually constructed shampoo and soap niches a thing of the past. The perfect spot for your soap, shampoo, conditioner, razor, shaving cream, body scrub, body wash, and other personal care items, the Tile Redi recessed shower shelf also eliminates the need for bulky shower racks and soap dishes that take up space in your shower or bath. The Redi Niche 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 niche with the included 6 lb set of Redi Poxy Epoxy Adhesive Tile Setting Material. No additional waterproofing is necessary!
