Formidable Integrity Without Compromise.

The Roca Duplo One Under Window Frame and Cistern is a specialist solution designed specifically for wall hung toilets in spaces with restricted height, allowing you to achieve that coveted floating aesthetic without being limited.

The Low Profile Powerhouse

Standing at a reduced height of 820mm, it is engineered to provide absolute structural stability while maintaining a compact footprint. The steel frame is self supporting and built to hold the full weight of a wall-hung WC, ensuring a rock solid foundation. Despite its shorter stature, it delivers the same premium performance as Roca’s full-height models, including a robust dynamic pressure range of 0.1 to 10 bar.

Top or Front Facing Flexibility

The Duplo One Under Window system is designed for maximum versatility in tight spots. One of its standout professional features is the dual mount flush plate compatibility; depending on your specific cabinetry or wall depth, you can choose to install the flush plate on the front of the cistern or on the top surface.

Whisper Quiet and Eco Conscious

Wrapped in a dense insulation jacket, the cistern operates with quiet discretion. This insulation prevents the echo of water refilling and stops condensation from forming inside the wall, protecting your woodwork and masonry for decades. The system features a dual-flush mechanism, allowing you to minimize water consumption while maintaining a powerful flush.
