Brief Information on Preformed Shower Niches
Installing a preformed shower niche is an easy way to add functionality to your new shower. Choose the proper location for your niche. It should be placed at a comfortable height, out of the water’s flow as much as possible. Next frame a rough opening ¼-inch larger in height and width than the niche.
Place the shower niche in the opening with the face flange level with the shower’s wall board. Secure the niche to the wall with screws. Apply waterproof membrane tape to the flange and interior of the niche to waterproof the surface and help mortar adhere during tiling.
