Geberit Sigma 8 Duofix Concealed Cistern & Frame 114 cm

The Specialist’s Verdict: Evolution, Not Revolution

The best part about the Duofix 4 is what hasn’t changed. Geberit has kept all dimensions and technical details identical to the current model, ensuring seamless compatibility with existing Rough-In plans.

The Key Upgrades: * Faster Installation: New Hexalobular socket (TX) screws and additional markings on the frame make one-person installation faster and more precise. * Optimized Hydraulics: Featuring the latest high-performance flush valve and a Type 383 quiet inlet valve for minimal noise. * Eco-Conscious: A sophisticated new design that results in 10% fewer CO2 emissions during production compared to its predecessor.

The Duofix 4 introduces several clever mechanical refinements designed to solve common on-site obstacles:

Pull-Out Side Fastening Plate: Allows for secure mounting on vertical studs in room-height applications.

Flexible Wall Anchors: An additional fastening hole allows you to adjust the anchor position to avoid obstacles like cables or pipes behind the wall.

Clever Foot Plate: Includes a hollow space so it can be mounted directly over fastening screws on the floor profile without interference.

Extended Reach: Suitable for floor constructions up to 25 cm high, giving you more flexibility in modern apartment builds.

The Duofix 4 is designed to pair perfectly with the new Geberit Sigma40 Actuator Plates.

• Integrated Odour Extraction: Pair your Sigma 8 frame with a Sigma40 plate to take advantage of Geberit’s built-in air purification technology.
