Shower niche waterproofing — where most niches actually fail.
A niche is a hole cut into your shower wall. More corners, more seams, more ways for water to get behind the tile.
Swipe for the 5 details that keep it dry:
→ Slope the bottom out
→ Wrap all 5 faces with membrane
→ Reinforce the inside corners
→ No screws through the wet area
→ Preformed or site-built, the detailing still matters
We stock prefab niches + the Schluter and MAPEI systems to seal them in.
