It takes time to build a truly waterproof tiled shower niche, but using one of Schluter’s kits can speed up the job. Made from the company’s 1/2-inch-thick Kerdi-Board tile backer, Prefabricated Shower Niches have presealed inside corners and 2-inch-wide integrated flanges that sit flush with the surrounding wall. They come in four sizes, from 12 by 6 inches to 12 by 28 inches; the larger models include an optional shelf that can be set to any height before tile is laid. Prices range from $55 to $105.
