The Schluter Kerdi-Board-SN is a prefabricated shower niche made of 1/2-inch Kerdi-Board, sealed at the corners and shipped with a Kerdi-Band frame, screws and washers. It drops into a framed opening and bonds directly into a Kerdi or Kerdi-Board shower assembly, so the waterproofing is built in rather than built up on site. That makes it faster and more predictable than a site-built niche lined with membrane, and it competes with foam niches from other waterproofing brands that work the same way. It suits remodelers and DIY tilers already using the Schluter system; the discontinued shelf on the two larger sizes is the main complaint owners raised.

Owners and installers describe the niche as a fast, reliable way to get a waterproof recess, and most praise how cleanly it ties into Kerdi assemblies. The recurring complaint is the prefabricated shelf on the larger sizes, which many found bulky and removed.
The Schluter KERDI-BOARD-SN is a prefabricated shower niche. It is fully waterproof and vapor-tight, and it has sealed inside corners. It integrates with KERDI and KERDI-BOARD shower assemblies.
The niche is made of 1/2" thick KERDI-BOARD. Every size comes with a waterproof KERDI-BAND frame to seal the seams, plus screws and washers for fastening it to stud framing.
Install it between wall studs for proper support and stability. KERDI-BOARD requires 16" (40 cm) stud spacing, so wider spacing needs additional studs. The prefabricated KERDI-BOARD shelf that came with the two larger niches is being discontinued.
