ROCA Duplo S Under Window Wall Hung Frame and Cistern

An Evolution of the Under Window Installation.

The Roca Duplo S represents the next generation of installation systems, specifically re-engineered to provide a solution for the most challenging bathroom layouts. This under window frame is the definitive choice for the sophisticated wet room where a wall-hung WC is desired beneath a window, or low level ledge wall. Standing at a compact 820mm, the Duplo S system allows you to maintain your architectural views and natural light while achieving a stunning floating aesthetic that exudes modern luxury.

The "S" Standard: Slimmer and Stronger

Part of the newly evolved Duplo S collection, this frame features a refined, high strength steel structure designed to be even reliable for the homeowner. The frame serves as a solid foundation, effortlessly carrying the weight of any wall-hung WC. Despite its reduced height, the Duplo S doesn't sacrifice performance, while maintaining a slender profile that fits comfortably within a 150mm depth, ensuring your bathroom feels open and expansive.

Dual Access Versatility:

Recognizing that under window or low ledge installations often come with unique spatial hurdles, the Duplo S is designed for ultimate flexibility. The system supports dual-option flush plate mounting, allowing you to choose between a traditional front facing plate or a top mounted plate. This makes it an ideal partner for installations within custom units or beneath deep window sills, ensuring the controls are always exactly where you need them.

Whisper Quiet Innovation and Thermal Protection

The cistern is fully encased in a high density insulation jacket. This shielding acts as a powerful sound barrier, dampening the noise of the tank refilling to an incredibly quiet level. Furthermore, this thermal jacket prevents the formation of condensation on the exterior of the cistern, a vital safeguard that protects your internal wall structure and floor from the long term risks of moisture and dampness.

Ecological Precision and Seamless Maintenance

The Duplo S is equipped with a high performance dual flush mechanism enabling significant water savings to meet modern sustainability standards. Maintenance is designed to be completely non-intrusive; every internal valve and working part is accessible through the flush plate aperture. This easy access design ensures that any future servicing can be completed in minutes without ever having to touch a single tile or disturb your wall finish.
