The wedi Sanwell niche is a factory-made, prefabricated wall niche element built from wedi's waterproof XPS building board. Unlike site-built timber-framed niches that require separate waterproofing, the Sanwell arrives with all internal joints factory-sealed — the entire element is waterproof to the core from the moment it leaves the box. Bond it into the wall recess using wedi system adhesive, tile directly over the surface with wedi 320 tile adhesive, and the niche is complete. No tanking membrane. No additional construction. No risk of future water ingress behind the tiles.

As part of the wedi building board system, Sanwell niches integrate seamlessly with wedi tile backer boards on the surrounding walls, creating a continuous, fully waterproof substrate across the entire shower enclosure. For a premium, grout-free finish, the Sanwell Top design surface can be bonded directly to the niche substrate, eliminating grout lines entirely for a sleek, low-maintenance result.
