Product Description

Geberit Duofix 1120mm Wall Hung WC Frame with Square Chrome Flush Plate – 458.040.21.2

The Geberit Duofix 1120mm Wall Hung WC Frame provides a strong support system for a compatible wall-hung toilet pan. It includes an Alpha concealed cistern, fixing kit and Alpha01 square chrome dual-flush plate.

Geberit designed this WC frame for installation within suitable metal or timber stud walls. Once installed, the frame and cistern sit behind the finished wall. As a result, the bathroom gains a neat, modern look with less visible pipework.

The concealed cistern uses a dual-flush system with a factory setting of 6 or 3 litres. Therefore, users can select the flush volume that suits each use. The square chrome Alpha01 flush plate also provides access to the cistern for future servicing.

Please note that this package does not include the wall-hung toilet pan or toilet seat. Therefore, you will need to choose a compatible pan and any other parts required for the installation.

Where Can You Use This Geberit WC Frame?

The Geberit Duofix frame suits modern bathrooms, en suites, cloakrooms and new-build projects. It can also work well during bathroom renovations where the installer plans to fit a wall-hung toilet.

The frame fits within a suitable metal or timber stud wall. Therefore, it provides a useful option for bathrooms where you want to hide the cistern and main plumbing behind the finished surface.

However, the wall and floor must support the complete installation. For this reason, ask a qualified installer to check the site before you order.

Why Choose a Wall-Hung Toilet Frame?

A wall-hung toilet frame supports the pan while hiding the cistern behind the wall. As a result, the bathroom gains a simple and tidy finish.

First, the raised toilet pan leaves the floor clear and makes cleaning easier. Next, the concealed cistern reduces visible parts. Finally, the square chrome flush plate adds a smart finishing touch and provides access for servicing.

The frame can also help the fitter set the toilet pan at a suitable height. However, the installer must follow the latest Geberit instructions to ensure a safe and secure fit.

Why Choose Geberit Duofix?

Geberit is a well-known maker of sanitary and bathroom systems. The Duofix range provides a practical support system for wall-hung toilets and concealed cisterns.

This package combines the frame, cistern, fixing kit and flush plate. Therefore, it helps reduce the need to buy each main item separately. In addition, the dual-flush cistern gives users a choice of two flush volumes.

Installation Advice

A skilled installer should fit the frame, cistern and wall-hung toilet pan. The installer must secure the frame to a suitable floor and supporting structure. They must also follow Geberit’s latest fitting instructions.

Before closing the wall, the installer should test the water supply, flush system, waste connection and all joints. In addition, they should make sure the service opening remains easy to reach through the flush plate.
