The 6" Square Cleanout Cover is a larger-format grate option for KERDI-DRAIN that works with 6" (150mm) square drain frames rather than the standard 4" round assembly. It's the right choice when your design calls for a more substantial drain presence — or when water volume demands a larger surface opening for faster drainage.

The square format creates a different aesthetic from the round 4" drain — particularly effective in large-format tile showers where a square drain aligns with tile geometry, and in commercial or heavy-use residential showers where drain capacity matters.

Key differences from 4" drains

• Frame size: 6" × 6" square (vs. 4" round on standard units)
• Reveal: ~3/16" above tile surface (slightly more than the 4" Classic)
• Adjustment: Height and tilt only — no lateral adjustment on 6" frames (4" frames have lateral adjustment too)
• Drain body: Compatible with KERDI-DRAIN bodies that accommodate the 6" frame assembly
• Flow rate: Larger surface opening = faster drainage — appropriate for heavy-use showers and multiple showerheads

Who should use a 6" drain

• Large-format shower installations (72"+ in any dimension) with multiple water sources
• Commercial showers and gym facilities
• Wet rooms where a larger drain statement fits the scale of the space
• Designs using tile formats that align geometrically with a square drain element

Pro Tips

• Plan your tile layout around the 6" square footprint — in a 12" × 12" tile layout, the square drain fits neatly within a single tile unit, which makes centering and cutting cleaner
• The 3/16" reveal is slightly more prominent than a 4" drain — factor this into your finish selection to ensure it complements rather than clashes with the tile
• Without lateral adjustment, precise drain body placement matters more — set the body with a framing square and check alignment before mortar sets
• Available in stainless steel finish — the square format in brushed stainless is a strong design statement in contemporary large-format tile showers
