Premium Shower Curb Overlay Kit, Central ABS Flange, Stainless Steel Grate, Cuttable Shower Curbs & Trowel

Transform Your Bathroom with a Watertight, Professional-Grade Shower Installation

Achieve a sleek, waterproof, and long-lasting shower floor with our 48"x48" Watertight Shower Curb Kit. Designed for both professional contractors and DIY renovators, this all-in-one kit includes everything you need to create a maintenance-free, leak-proof shower pan.


Premium EPS Shower Tray for Reliable Waterproofing

Our shower curb overlay features a high-density EPS foam shower tray with a 4" ABS central bonding flange for efficient drainage. Measuring 48" x 48", the tray is pre-sloped at a 5° incline from all four sides toward the drain, ensuring water flows directly into the 4" stainless steel grate without pooling. A textured, water-impermeable surface makes mortar application effortless and secure.


Cuttable Shower Curbs for Custom Fit

Included are two cuttable shower curbs (48" × 4.5" × 6"), made from durable XPS plastic extruded board. They are lightweight, easy to trim, and adaptable to various shower dimensions, allowing you to build a perfectly sealed edge for your shower area.


Complete Waterproof Membrane Protection

This kit includes HDPE water-impermeable membranes in two roll sizes, perfect for wall and floor coverage. With four pre-formed inside corners and two outside corners, installation is quick, seamless, and eliminates the need for tedious measuring and cutting.


Professional Tools for a Flawless Finish

Unlike many other kits, ours includes a stainless steel square-toothed trowel for mortar spreading. The serrated blade design helps create an optimal bond between the waterproof membrane and your wall or floor surfaces.


Effortless Installation for Lasting Results

Whether you're a seasoned installer or tackling your first bathroom renovation, this shower pan slope kit is straightforward to assemble. Just pair it with an unmodified thin-set mortar, and you'll have a watertight shower base built to last.
