Product Description

Roca Duplo One Under-Window WC Frame with Cistern – A8900720A0

The Roca Duplo One Under-Window WC Frame with Cistern provides a low-height support system for a compatible wall-hung toilet. Its wide, low design makes it a useful choice for bathrooms where a standard 1120mm frame would be too tall.

The complete frame measures only 530mm high. Therefore, it may fit beneath a suitable window, shelf or low bathroom ledge. Once installed, the steel frame and cistern sit behind the finished wall, helping to create a neat and modern appearance.

The strong frame supports a compatible wall-hung WC pan. Meanwhile, the concealed cistern provides a 6/3 litre dual flush. As a result, users can choose between a full and reduced flush.

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, seat or flush plate. You will need to choose compatible products separately.

What Comes in the Box?

• 1 x Roca Duplo One under-window steel WC frame
• 1 x concealed dual-flush cistern

Where Can You Use This Under-Window WC Frame?

The Roca Duplo One under-window frame may suit bathrooms with low windows, sloped ceilings or limited wall height. It can also work well beneath shelves and suitable bathroom ledges.

Its 530mm height offers more flexibility than a standard full-height frame. However, its 790mm width means that you must also check the available horizontal space.

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

Why Choose an Under-Window Toilet Frame?

A standard WC frame often measures around 1120mm high. In contrast, this Roca under-window frame measures only 530mm high. Therefore, it can provide a practical solution where vertical space is limited.

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

The wide frame design also spreads the installation across a lower area. As a result, it can sit beneath a suitable window while still supporting the toilet pan.

Roca Duplo One Flush Plate Compatibility

This WC frame requires a compatible Roca Duplo One operating plate. Depending on the exact model and finish, suitable 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 also offers selected electronic Duplo One operating plates. However, always check the exact plate reference and compatibility before ordering.

Why Choose Roca Duplo One?

Roca is a well-known maker of bathroom products and installation systems. The Duplo One range includes full-height, compact and under-window frames for different bathroom layouts.

This model combines a low 530mm height with a concealed dual-flush cistern. Therefore, it offers a useful way to fit a wall-hung toilet beneath a window or in another height-restricted area.

In addition, the front-operated flush system provides access to the working parts. This opening helps make future checks and maintenance easier.

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 check the window sill, finished pan height and flush plate position. This check is important because the low frame may affect the final position of the operating plate and ledge.

Manufacturer Warranty

• Up to 10-year manufacturer warranty on the Duplo One steel frame
• Up to 5-year manufacturer warranty on the concealed cistern
• Up to 2-year manufacturer warranty on compatible Duplo One flush plates

All warranty periods remain subject to Roca’s current terms, correct installation and registration requirements where applicable. Please note that this package does not include a flush plate.
