Understanding the Low Profile Acrylic Advantage
The structural integrity of a shower base relies heavily on what supports its surface. Think of this acrylic and ABS shell like a supportive architectural bridge, where the outer high gloss layer provides a smooth waterproof shield while hidden fiberglass reinforcement handles the weight distribution underneath. This multi-layer design prevents flexing and helps maintain a rigid, stable floor during daily use. By utilizing integrated tile flanges along two sides, the base forms a reliable barrier against moisture penetration, keeping your subfloor protected much like flashing on a roof keeps water away from interior walls.
Installation Guide
Ensure the subfloor is clean, level, and structurally sound prior to setting the shower base.
Confirm the 2-wall corner alcove matches the 48 by 34 inch rectangular dimensions.
Position the base carefully to align the integrated tile flanges with the wall studs for proper waterproofing.
Connect a standard compression fitting drain to the ready opening, noting that the drain itself is not included.
Care & Maintenance
Routine Cleaning Wipe down the acrylic surface regularly using a soft cloth or sponge with mild soap and warm water.
Stain Removal Use non-abrasive liquid cleaners designed for acrylic to address stubborn spots without scratching the finish.
Rinse Thoroughly Always rinse the shower floor with clean water after applying any cleaning solutions to prevent residue buildup.
Avoid Harsh Chemicals Never use abrasive scouring powders, steel wool, or harsh solvent-based chemicals on the high gloss surface.
Inspect Caulking Periodically check the seal between the integrated tile flange and wall materials to maintain long-term waterproofing.
