Understanding Integrated Tile Flanges and Structural Support
When installing a shower base, keeping water where it belongs is priority number one. Think of integrated tile flanges like the overlapping shingles on a roof; they act as built-in vertical barriers along the wall sides of the tray that prevent water from seeping behind the drywall. Combined with the underlying fiberglass-reinforced acrylic capped ABS structure, this design provides a rigid platform that resists flexing under foot traffic, ensuring your waterproof seal remains intact year after year.
Installation Guide
Ensure the subfloor is completely level, clean, and structurally sound prior to setting the shower base in place.
Dry-fit the shower base to check alignment with your standard compression fitting drain opening before applying mortar or adhesive.
Secure the integrated tile flanges directly to the wall studs to stabilize the unit and assist with proper wallboard overlap.
Review local plumbing codes in your state to ensure all drain connections and installations meet regional standards.
Care & Maintenance
Routine Cleaning Wipe down the acrylic surface weekly using a soft sponge or microfiber cloth and mild liquid dish soap.
Stain Prevention Rinse the shower floor thoroughly after each use to remove soap residue and body wash buildup.
Avoid Abrasives Never use scouring powders, steel wool, or harsh chemical solvents, as they can dull the high gloss finish.
Hard Water Care Remove mineral deposits using a vinegar and water solution, rinsing thoroughly with clean water afterward.
Scratch Maintenance Minor surface scuffs on the acrylic material can often be buffed out using a specialized acrylic polish.
