Membrane shower installations have a specific requirement: the drain body needs to bond with the membrane, and the head needs to adjust to meet the finished floor elevation regardless of tile thickness or mortar bed depth. This drain is built for exactly that scenario.
The ABS body provides a stable, chemically compatible base for standard shower membranes. The adjustable nickel head assembly rises or drops to meet the finished floor surface precisely, eliminating the gap or proud edge that causes membrane failures and water ingress over time.
- Adjustable head assembly — rises and drops to meet finished floor elevations regardless of tile thickness or mortar bed depth; eliminates the fit issues that cause membrane failures.
- ABS drain body — chemically compatible with standard shower membranes; provides a stable bonding surface for waterproofing systems.
- 5-inch nickel head — the larger head surface provides more drainage area than standard 4-inch drains; the nickel finish coordinates with brushed nickel tapware.
- Beveled clamping collar — simplifies subfloor installation and creates a secure, watertight connection between the drain body and the membrane.
- 2-inch threaded outlet — connects over 2-inch and inside 3-inch schedule 40 DWV pipe; compatible with standard residential plumbing.
