Product Description

Roca Duplo One Compact WC Concealed Cistern and Frame – A8900730A0

The Roca Duplo One Compact WC Concealed Cistern and Frame provides a slim support system for a compatible wall-hung toilet. It combines a strong steel frame with a concealed dual-flush cistern, helping installers create a neat and modern bathroom finish.

At only 90mm deep, the complete frame offers a useful option where installation space is limited. Once fitted, the frame and cistern sit behind the finished wall. As a result, the bathroom gains a clean appearance with less visible pipework.

The steel frame supports a compatible wall-hung WC pan. Meanwhile, the concealed cistern provides a choice of 4/2, 4.5/3 or 6/3 litre flush settings. Therefore, the installer can choose a setting that suits the toilet pan and installation.

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

Where Can You Use This Compact WC Frame?

The Roca Duplo One compact 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.

Its 90mm depth makes it a useful option for bathrooms with limited installation space. However, the complete finished wall will need extra depth for pipework and wall materials.

The frame must connect to a suitable floor and supporting wall structure. Therefore, always ask a skilled installer to check the site before you buy.

Why Choose a Compact Wall-Hung WC Frame?

A compact WC frame can reduce the space needed behind a wall-hung toilet. As a result, it may help installers create a slimmer service wall and make better use of the room.

First, the steel frame supports the wall-hung pan. Next, the concealed cistern hides behind the finished wall. Finally, the raised toilet pan leaves the floor clear and makes cleaning easier.

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.

Roca Duplo One Flush Plate Compatibility

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

• Roca PL1 flush plates
• Roca PL2 flush plates
• Roca PL3 and PL3 Pro flush plates
• Roca PL7 flush plates
• Roca PL10 flush plates
• Roca EP1 flush plates
• Roca EP2 flush plates
• Roca EP3 flush plates

Flush plate ranges can include different colours, finishes and controls. Therefore, check the exact plate reference and compatibility before ordering.

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 the wall covering goes into place.
