SharpSlope Wet Room Shower Tray Base Kit Square Panel Drain

The SharpSlope wet room shower tray base kit is purpose-built to provide a completely waterproof foundation for walk-in showers and wet rooms in homes with either timber or concrete floors. Supplied as a full kit with all components needed for tanking, it suits both sleek modern and minimalist interiors and can be adapted to bathrooms and shower spaces of various sizes. The tray base features a water-resistant extruded polystyrene foam core with an ultra-low installation height and a pre-formed 4-way drainage slope. Its cement-coated top surface allows direct tiling without the need for extra preparation. The base is entirely watertight and structurally stable, unaffected by humidity, water exposure, or minor subfloor movement.

Drain covers are available in multiple styles, including stainless steel grates and premium-finish drain panels. The drain panels can be flipped to allow for tile inserts, letting the drain blend perfectly with surrounding tiles to create a seamless wetroom finish. (See product images for examples with and without tile inserts) For installation guidance, watch the installation video or refer to the Installation Instructions PDF in the Product Downloads section.
