Product Description

Roca Duplo One 1120mm WC Frame with Dual-Flush Cistern – A8900700A0

The Roca Duplo One WC Frame with Dual-Flush Cistern provides a strong concealed support system for a compatible wall-hung toilet. It combines a full-height steel frame with a concealed cistern, helping installers create a neat and modern bathroom finish.

Once installed, the frame and cistern sit behind the finished wall. As a result, the bathroom gains a clean appearance with less visible pipework. In addition, the wall-hung toilet pan leaves the floor clear and makes cleaning easier.

The concealed cistern supports 4/2, 4.5/3 and 6/3 litre flush settings. Therefore, the installer can select a suitable setting for the toilet pan and installation. Roca presets the cistern to a 6/3 litre dual flush.

The system uses a front-operated flush plate, which also provides access for future servicing. However, this package does not include the toilet pan, toilet seat or operating plate. You will need to choose compatible products separately.

Where Can You Use This Roca WC Frame?

The Roca Duplo One frame may suit modern bathrooms, en suites, cloakrooms and new-build projects. It can also work well during bathroom renovations where the installer wants to fit a wall-hung toilet.

The full-height frame supports a compatible wall-hung WC pan while the cistern remains out of sight. Therefore, it provides a practical option for bathrooms where you want a clean, uncluttered look.

However, the frame must connect to a suitable floor and supporting wall structure. For this reason, always ask a skilled installer to check the site before you buy.

Why Choose a Wall-Hung WC Frame?

A WC frame supports the wall-hung toilet pan and hides the cistern behind the finished wall. As a result, only the toilet pan and flush plate remain visible.

First, the steel frame gives the pan firm support. Next, the raised pan keeps the floor clear. Finally, the concealed cistern reduces visible parts and creates a simple bathroom finish.

The front flush plate opening also provides access to the cistern’s working parts. Therefore, an installer can carry out future maintenance without removing the complete wall.

This WC frame requires a compatible Roca Duplo One operating plate. Depending on the exact plate and installation, compatible ranges may include:

• Roca PL1 flush plates
• Roca PL2 flush plates

• Roca PL10 flush plates

Installation Advice

A skilled bathroom installer or plumber should fit the frame and concealed cistern. The installer must secure the steel frame to a suitable floor and supporting structure. They must also follow Roca’s latest installation instructions.

Before closing the wall, the installer should test the water supply, cistern, flush system, waste connection and all joints. In addition, they must keep the front service opening clear for future access.

The installer should also confirm the finished pan height and flush plate position before fixing the frame. This check can help avoid changes after fitting the wall covering.
