The Ultimate Foundation for Your Wall Hung Toilet.

The Roca Duplo S Full Height Installation System is the go to choice for creating a sophisticated, floating bathroom aesthetic. Standing at 1120mm, this heavy duty steel frame provides a rock solid foundation for wall-hung toilets, concealing all plumbing behind the wall to reveal a clean finish. By removing the traditional toilet base from the floor, it creates a sense of expanded space and also simplifies cleaning.

Advanced Engineering and Silent Performance

The Duplo S collection represents the evolution of installation technology. The frame is engineered for absolute stability, easily carrying the weight of the WC without movement. To ensure a premium experience, the cistern is wrapped in a high density  insulation jacket. This provides a dual benefit: it acts as a thermal barrier to prevent condensation from forming inside your walls and delivers superior acoustic insulation, ensuring every flush is whisper-quiet and discreet.

Water-Saving Precision with 4/2 Litre Flush Leading the way in environmental stewardship, this Duplo S model features a 4/2 litre dual-flush system. This offers significant water savings compared to standard cisterns, helping to reduce utility bills and lower your home’s ecological footprint without sacrificing power.

Effortless Installation and Maintenance

Designed with both the installer and homeowner in mind, the Duplo S features intuitive height-adjustable feet and a versatile 110mm drainage diameter. Maintenance is completely stress free; all internal components are fully accessible through the flush plate aperture. This easy access design ensures that any future servicing can be completed swiftly without the need to remove tiles or disturb your finished wall, guaranteeing years of reliable performance.
