About this product
Duofix Sigma 1140mm Wall Hung WC Frame & Slimline Cistern with Sigma01 Square Flush Plate
From Geberit's Sigma collection, this Duofix wall-hung WC frame and slimline cistern bundle pairs the Sigma 1140mm frame with a slim 80mm-deep cistern and the Sigma01 square flush plate. The square-format plate complements clean-lined, contemporary WC pans, while the slimline cistern depth makes this an ideal solution where pre-wall space is limited.

- Construction height 1140mm, suitable for part- or full-height pre-wall and partition wall installations
- Supports wall-hung WC pans with a projection up to 700mm — strength-tested to 400kg when combined with Geberit wall-hung pans
- Fully insulated concealed cistern — prevents condensation build-up
- WRAS approved — water supply components certified for UK use
- Compatible with Geberit AquaClean shower toilets, DuoFresh odour extraction, and 100+ Sigma flush plate finishes
- Sigma01 square flush plate — frameless design with water-saving dual flush, sound-absorbing actuator rods, and tool-free fast adjustment
- Flush plate includes mounting frame, distance bolts, and actuator rods
