Our take on the Schluter KERDI-DRAIN Bonding Flange Drain

The Schluter KERDI-DRAIN is a 2-inch PVC shower drain with an integrated bonding flange. The flange lets you bond KERDI waterproofing membrane directly to the drain, so the waterproof layer ties into the drain body instead of relying on a clamping ring. It fits KERDI-SHOWER-T/-TS/-TT trays and mortar-bed installations. At $31.88 at eBay as of November 4, 2026, it sits at the low end of its recent range, with 5 stores pricing it new.

Pros
  • Integrated bonding flange gives a continuous waterproof connection
  • Works with KERDI-SHOWER trays and mortar beds
  • 2-inch threaded or no-hub outlet fits standard plumbing
  • PVC body is inexpensive and widely available
  • Part of a complete Schluter system with matching membranes and drains
Cons
  • Requires KERDI membrane and Schluter-specific technique to get the bond right
  • Grey PVC finish is utilitarian, not a decorative drain cover
  • Grate and drain cover are often sold separately
  • No clamping ring, so it is not a drop-in swap for older drains

What reviewers say

Owners and tile setters generally rate the KERDI-DRAIN well, mainly for how cleanly the membrane bonds to the flange and how few leaks show up later. Complaints center on the learning curve and on buying the grate separately.

Pros
  • Reliable waterproof connection at the drain
  • Fits KERDI-SHOWER trays without modification
  • Fewer leak callbacks than clamping-ring drains
Cons
  • Installation mistakes are costly if the membrane bond is poor
  • Grate sold separately adds cost
  • PVC body feels light compared with cast-iron drains

Questions and answers

Is the KERDI-DRAIN worth it over a standard clamping-ring drain?
For a KERDI shower, yes. The bonding flange lets the waterproof membrane seal directly to the drain, which removes the clamping ring and the leak path around it. For a non-Schluter build, a standard drain is simpler.
What size pipe does it connect to?
It takes a 2-inch outlet, available as threaded or no-hub. Match the outlet type to your plumbing rough-in before ordering.
Does it work with KERDI-SHOWER trays?
Yes. It is made for KERDI-SHOWER-T, -TS and -TT trays and also works in mortar-bed showers.
Is the drain grate included?
The listing includes the flange. Grates and covers are usually sold separately, so check before you buy.
