In the past when if you wanted recessed shelving in your shower you had to construct it by framing it out, cladding it with cement board and covering it with a waterproof membrane.
ProSpec niches are designed to make life easier for the contractor and do-it-yourselfer alike. If you plan to cut out part of a wall in a wet area, like a shower, installations must be done correctly. Improperly installed or poorly waterproofed niches can result in problems with mold and rot. When installed according to these simple instructions, ProSpec niches provide beautiful recessed shelving that is waterproof and worry-free.
