Description wedi Sanwell Tileable Shower Niches are prefabricated wall niches used to create tiled storage shelves/areas in bathrooms and wet rooms, for storing bath and shower utensils. They provide a factory-made, watertight element that can be easily installed and saves a lot of time compared to constructing the element by hand. wedi Sanwell Tileable Shower Niches are constructed from the same materials as the wedi Tile Backer Board, each niche consists of a blue core made from extruded polystyrene rigid foam that is reinforced with glass fibre (with alkali-resistant finish) on both sides and coated with a polymer-modified cement. This core is 100% waterproof and remains fully functional even after possible damage. wedi Sanwell Tileable Shower Niches are available in two sizes – 20/40 and 30/60, made from either 10mm or 12.5mm thick wedi Board.
