 High-Quality Shower Tray – Made from EPS high-pressure foam board, our shower pan slope sticks ensure optimal drainage with a 5° inclination toward the 4" ABS central bonding flange. The gray water-impermeable membrane features a fluffy texture for superior mortar adhesion.

Bonus Stainless Steel Trowel – Unlike other kits, ours includes a rust-resistant, square-toothed trowel for even mortar application, ensuring a strong bond between the membrane and surfaces.
