This document provides installation and maintenance instructions for the SERA 1236-MB-NIC-3 shower niche. The installation process involves cutting into the wall, framing, waterproofing, and sealing. Important: You must wait 48 hours for the sealant to cure before using the shower.
Installation Steps
- Locate and Mark: Use a stud finder to locate adjacent framing studs. Mark the center lines and draw a level line at your desired height.
- Cut the Wall: Trace the cutline with a pencil above the center line and cut out the wall board.
- Level and Fasten: Level and fasten the surrounding framing to adjacent vertical studs, ensuring the dimensions match the niche flange.
- Waterproofing: Glue a waterproofing membrane inside to seal the whole cave and extend 6 inches to the four sides of the surrounding wall.
- Tile and Set: Apply setting material and set your tile, marble, or stone directly to the shower wall.
- Seal: Remove the protective film from the tape and apply an uninterrupted bead of silicone sealant from the inside corner of the niche to the edge.
- Insert Niche: Insert the niche fixture into the cave. Press the flange tightly and ensure the niche is plumb and level. Wipe off excess sealant.
- Finish: Tape the flanges to the wall to hold the niche in place until the sealant cures.
Waterproofing Details
In accordance with local building codes, apply waterproofing to the niche as required. The waterproofing membrane must meet ANSI A118.10 standards.
Care & Maintenance
To keep your shower niche in good condition, follow these guidelines:
- Cleaning: Periodically clean the fixture with mild liquid dish detergent and a clean rag.
- Removing Stains: If you encounter "yellow spots" on the brushed surface, use a scour pad to remove them, always brushing in the direction of the grain.
- Avoid: Do not use abrasive cleaners, ammoniated products, rubbing alcohol, detergents, astringents, chlorine bleach-based cleaners, or harsh polishes, as these may void the warranty.
- Chemicals: If using chlorine bleach in your shower, avoid contact with the niche surface and rinse immediately if any residue ends up on the niche.
