Save Water With Clear Dual-Flush Controls
Sigma30’s two large buttons make it obvious to choose a reduced or full flush, supporting the dual-flush volumes of your compatible Geberit Sigma tank (e.g., 1.28/0.8 or 1.6/0.8 GPF models). Clear visuals encourage the right choice without extra labels—good for homes and guest spaces alike.
Everyday Performance You Can Feel
Front actuation with sound-absorbing rods keeps operation smooth and quiet. With an actuation force under 20 N, the plate is comfortable for daily use and can be positioned to meet accessibility targets when installed at code heights.
Durable, Easy-Clean Surfaces
The molded-plastic body resists bathroom humidity and fingerprinting better than many metal finishes, while the polished-chrome face and matte-chrome accent stripe deliver a crisp, modern look. A quick wipe with a soft cloth restores the shine.
Installer-Friendly From The Box
Everything needed for the actuation side is included: mounting frame, distance bolts, and adjustable actuator rods. Fine-tune rod length tool-free to match the tank’s mechanism, then snap the plate in place—no special tools required.
Sized Right For Tile Layouts
At roughly 9.7" × 6.5" with a slim ~0.5" profile, Sigma30 fits neatly within common tile patterns and backsplash heights. Its low projection helps keep the wall plane clean above the bowl.
Sigma System Compatibility
Use this plate exclusively with Geberit Sigma concealed cisterns/carriers (2x4 and 2x6). It is not compatible with Geberit Omega or Kappa series tanks. Check your carrier model before ordering to ensure a perfect match.
Accessibility & Code Confidence
Geberit identifies specific Sigma30 finishes—including this one—as ADA-compliant when installed per ADA/ICC A117.1 reach-range requirements, helping you meet project accessibility goals with a coordinated look.
