High-Performance Shower Tray with Slope Design

Equipped with a heavy-duty PVC bonding flange and an auxiliary drainage device for 2" pipes, this kit prevents water pooling and keeps your pipes clear with its gravity automatic seal grate.


Cuttable Shower Curbs for Custom Fit

The two included shower curbs (38" x 4.5" x 6") are made from XPS extruded board, easy to cut, and adaptable to your shower size. Perfect for creating a clean, professional curb that matches your layout.
