Building Products Prova Niche 24 In. X 16 In. With Adjustable Shelf

PROVA-NICHE is a pre-fabricated shelf made with a fully waterproof extruded polystyrene (XPS) core that is sandwiched between tightly woven mesh and layers of cementitious coating to create a fully waterproof barrier. The coating also provides more rigidity in the product making it easier to work with. The PROVA-NICHE is ready to tile out of the box. Seams between the niche & walls and fastener holes are waterproofed with PROVA-SEAL during installation and no additional waterproofing is needed. This useful and stylish accessory can be used to hold shampoo bottles, soap and other necessities while saving floor space in a tiled shower. PROVA-NICHE can be used with PROVA-MAT and PROVA-BOARD PLUS when installing a tiled shower.
