A 4" square grate with a flowing curved-line pattern — the Trendline Curve grate turns your shower drain into a subtle design detail instead of a utility piece you're trying to hide. It's the same high-quality stainless steel frame system as the Classic grate, just with more personality.

This is a grate-only kit. It mounts to a KERDI-DRAIN body already installed in your shower floor (sold separately). The adjustable frame accommodates tile thicknesses from approximately 1/8" to 1", so it works with everything from slim porcelain to thick natural stone.

How KERDI-DRAIN grates work

The Trendline grates use Schluter's height-adjustment collar plus a lateral adjustment ring — you can fine-tune the grate position both up/down and side-to-side to sit perfectly flush with the surrounding tile. No shimming, no caulk gaps. The drain body bonds directly to the KERDI waterproofing membrane via the fleece-covered bonding flange, creating a waterproof connection at the most vulnerable point in any shower.

Key specs

• Grate size: 4" × 4" square
• Frame material: Stainless steel
• Grate pattern: Curved line design
• Accommodates tile thickness: ~1/8" to 1"
• Height and lateral adjustment built in
• Fits KERDI-DRAIN 4" frames and compatible drain bodies

Grate pattern options

The Trendline series comes in three patterns — Curve (this one), Floral, and Pure (minimal grid). Same frame, different faces. Order whichever suits the design direction of the shower.

Pro Tip

Install the drain body and waterproof everything first — let that cure completely before setting tile. Then install the grate assembly during tiling so you can dial in the exact height to match your tile surface. Trying to adjust the grate height after grout is set is frustrating and avoidable.

• KERDI-DRAIN body (2" or 3" ABS, PVC, or stainless steel outlet)
