What size should a shower niche be?

Schluter-Systems says (read 2026-11-05): “Schluter®-KERDI-BOARD-SN is a prefabricated shower niche made of KERDI-BOARD that can be installed in both KERDI and KERDI-BOARD wall assemblies.” (source) “The shower niche features a 1/2" (12.5 mm) -thick by 2" (50 mm) -wide integrated bonding flange and is available in 12" x 6" (30 x 15 cm), 12" x 12" (30 x 30 cm), 12" x 20" (30 x 51 cm), and 12" x 28" (30 x 71 cm) sizes.” (source)

Are prefabricated shower niches better?

Schlüter-Systems (European guidance) says (read 2026-11-05): “The decision to use one method or the other depends on the type of project, the structural requirements, the dimensions required and the extent of design flexibility.” (source) “While bespoke sizes usually require a tailor-made niche, prefabricated elements can be used for standard dimensions or renovation projects.” (source)

Should a shower niche be sloped?

Schluter-Systems says (read 2026-11-05): “When using the KERDI-BOARD-SN prefabricated shelf, determine the desired height of the shelf and mark with a level line.” (source) “The shelf may be raised at the back to create a slope, or the tile may be set on a slope during the installation to prevent water from pooling in the finished application.” (source)

What should be waterproofed inside a shower niche?

Schluter-Systems says (read 2026-11-05): “Schluter®-DESIGN-NICHE is a prefabricated powder-coated aluminum wall niche.” (source) “Completely seal the gap between the frame and the body of the niche using KERDI-FIX.” (source) “Embed the KERDI-BAND frame around the niche, then tile the surrounding area per standard methods.” (source)

What affects the cost of a shower niche?

Schlüter-Systems (European guidance) says (read 2026-11-05): “The structure of the wall itself also has an influence, because solid concrete or stone walls require different preparatory work, tools and fastening materials than plasterboard walls, for example.” (source)

What should you check before buying a shower niche?

ARDEX Americas says (read 2026-11-05): “Install tiles following the general office outline procedure set forth in ANSI A108.5.” (source)
