Our niches are manufactured from a single piece of 100% waterproof XPS foam and then covered in fiberglass mesh and coated in our modified cement coating for both strength and ease of tiling. They install easily on any 16" OC stud wall without modifications. The HYDRO-BLOK Shower Caddy also provides a quick way to add a small storage shelf to any shower system.
