Understanding Integrated Tile Flanges
When installing a shower base, water containment is the most critical factor for preventing long-term wall damage. The integrated tile flanges on this shower tray act much like a built-in gutter system behind your wall panels or tiles. Instead of relying solely on surface caulking that can degrade over time, the upward-facing edge creates a physical barrier that directs any stray water droplets safely down into the basin. This engineering design streamlines the waterproofing process and gives you peace of mind that your subfloor remains protected.
Installation Guide
Ensure the subfloor is clean, level, and structurally sound before positioning the shower base.
Verify drain alignment with your left or right drain configuration choice prior to final setting.
Apply structural mortar or plaster beneath the base floor to provide solid support across the entire bottom surface.
Secure the integrated tile flanges directly to the wall studs to maintain stability and proper waterproofing alignment.
Care & Maintenance
Routine Cleaning Wash the acrylic surface regularly with warm water, mild dish soap, and a soft sponge.
Stain Removal Use a non-abrasive cleaner to gently lift stubborn marks without scratching the high gloss finish.
Avoid Harsh Chemicals Do not use abrasive scouring powders, steel wool, or harsh solvent-based cleaners on the acrylic material.
Rinse Thoroughly Always rinse soap residue away with clean water after each cleaning session to prevent film buildup.
Check Drains Periodically inspect the drain opening and surrounding area to ensure smooth water flow.
