If you already have a clamping-ring drain installed and want to add Schluter's waterproofing system, this adaptor kit is exactly what you need — no ripping out the drain, no starting over.

The KERDI-DRAIN-A flange integrates directly with your existing drain body, giving you the KERDI fabric bonding flange that makes the whole waterproofing system work. The stainless steel grate finishes it off with a clean look that won't rust or stain in a wet shower environment.

Works with the full KERDI system: Once this adaptor is in place, KERDI waterproofing membrane bonds directly to the flange — creating the continuous watertight barrier Schluter is known for.

Pro Tip: This is the right call when you're retiling an existing shower that already has a functional drain. Converting rather than replacing saves you the demo work and keeps the rough plumbing intact. Make sure your existing drain body is compatible with 5-1/2" clamping ring models before ordering.
