The most minimal of the Trendline grate options — a simple, clean grid pattern that disappears into modern and contemporary showers without calling attention to itself. If your design is leaning toward large-format tile, frameless glass, and clean lines, the Pure grate fits without competing.

Same stainless steel quality and adjustable frame system as the rest of the Schluter KERDI-DRAIN lineup. Grate-only kit — installs onto a KERDI-DRAIN body already in the floor (sold separately). Adjusts both vertically and laterally to sit flush with your tile surface.

How KERDI-DRAIN grates work

The height-adjustment collar and lateral adjustment ring let you dial the grate to sit perfectly flush with your tile — no shimming, no caulk lines. The drain body beneath bonds directly to the KERDI waterproofing membrane at its fleece-covered bonding flange. That bond is what makes a Schluter shower a sealed system rather than a "hope it doesn't leak" system.

When to choose Pure vs. Curve vs. Floral

Pure works best in clean contemporary or minimalist showers. Curve has a softer organic feel that works well in transitional designs. Floral is the statement piece — more detailed, more decorative. All three perform identically; the choice is purely aesthetic.

Pro Tip

If you're going for a truly invisible drain look, consider the KERDI-DRAIN Tile Grate instead — it's a frameless tileable cover where you set a small tile directly on the grate to match the floor exactly. The Pure grate is a close second for minimal appearance, but the Tile Grate is the real "where did the drain go?" option.

Pairs with

• KERDI-DRAIN body (2" or 3" ABS, PVC, or stainless steel outlet)
• KERDI waterproofing membrane
• KERDI-SHOWER tray (if using a prefab base)
