Is the KERDI-DRAIN worth it over a standard clamping drain?

For a bonded, tiled shower floor, yes. The integrated flange bonds directly to KERDI membrane, which removes the weak point where a clamping drain meets the waterproofing. A standard clamping drain is cheaper but needs a different waterproofing approach.

The KERDI-DRAIN 2" PVC drain body and a 4" stainless steel square grate. Membrane, thin-set, and pipe are sold separately.

Will it fit my 2" PVC drain pipe?

Yes. The 2" PVC outlet solvent-welds to standard 2" PVC drain pipe. If you have ABS or a 3" line, you need a different version.

How thick can my tile be?

The grate assembly handles tile from 1/4" to 1-1/4" thick. The frame reveal is about 1/8", so the grate sits nearly flush.

Can I use it with a foam shower tray?

Yes. It is designed for standard tiled showers on a mortar bed or a foam tray, and it bonds to KERDI and other Schluter membranes.

Our take on the Schluter KERDI-DRAIN 2" PVC with 4" Stainless Steel Square Drain

The KERDI-DRAIN is a shower drain body for bonded, tiled shower floors. Its integrated bonding flange ties directly into KERDI and other Schluter sheet membranes, which takes the guesswork out of the drain-to-membrane joint. The 2" PVC outlet solvent-welds to standard 2" PVC drain pipe, and the kit includes a 4" stainless steel square grate that adjusts flush with finished tile. At $80.08 at Amazon as of November 4, 2026, it sits at the low end of its recent range across 7 stores.

What reviewers say

Owners and installers generally rate the KERDI-DRAIN well for the bonding-flange design, which makes the membrane connection straightforward and leak-resistant. Complaints tend to focus on price and on the need to stay within the Schluter system.

Pros

Bonding flange simplifies waterproofing at the drain
Adjustable grate sits flush with tile
Sturdy stainless grate looks clean

Cons

Costs more than a basic clamping drain
Requires matching Schluter membrane and accessories
Limited outlet and grate options in this kit

About the Schluter KERDI-DRAIN 2" PVC with 4" Stainless Steel Square Drain

The Schluter KERDI-DRAIN 2" PVC shower drain is the drain body that anchors a bonded, tiled shower floor. It solves the hardest connection in any tile shower — where the drain meets the sheet membrane — with an integrated bonding flange that ties directly into KERDI and other Schluter membranes. If you're building a standard tiled shower on a mortar bed or foam tray, this is the step that locks the floor assembly together. Built for pros and DIYers.

The 2" PVC outlet solvent-welds to standard 2" PVC drain pipe, and the kit includes a 4" stainless steel square grate for a clean, modern finish. The grate height adjusts so you can set the drain flush with your finished tile.

Contractors reach for the KERDI-DRAIN because it takes the guesswork out of the drain-to-membrane joint. Tile Outlets stocks it alongside the trays, membrane, and thin-set you need to finish the shower.
