Radiant Thermaniche Curved Shower Niche — 350 x 450 x 90mm | Pre-Fabricated | 10-Year Warranty
The Radiant Thermaniche RSNC20 is a pre-fabricated curved shower niche in a compact portrait format — shorter than the RSNC21 (600mm height) and ideal where vertical wall space is more limited. Its curved profile adds a softened, architectural detail to the shower wall. Same waterproof polystyrene core construction and 10-year warranty as the rest of the Thermaniche range.
Fixings are included in the pack.

Why Pre-Fabricated?
A pre-fabricated niche eliminates the risk of water ingress behind the wall — one of the most common causes of shower waterproofing failures. The Thermaniche's waterproof construction means it can be tiled directly without additional waterproofing membranes on the niche itself, saving time and reducing installation complexity.
