ROCA Duplo One Tank Compact Concealed Cistern

Seamless Integration for the Refined Bathroom.

When creating a bathroom, the most powerful design elements are often the ones you cannot see. The Roca Duplo One Compact Concealed Cistern is the essential hidden component for those seeking the ultra clean back-to-wall aesthetic. Specifically engineered for floor standing toilets that sit flush against the wall, this system hides the bulky plumbing and water storage behind your tiling or dedicated furniture.

An Architectural Solution for Tight Spaces

In modern renovations, space is often a premium. This compact model features a thin 80mm depth. The ultra slim design allows the cistern to be tucked away into shallow stud walls, meaning you don't have to build out a thick, intrusive false wall just to hide your cistern. It is the perfect choice for compact en-suites and cloakrooms where every inch of floor space is vital.

Quiet and Built to Last

The unit is fully encased in a high density insulation jacket. This serves a vital dual purpose: it acts as an acoustic shield to dampen the sound of the tank refilling and, crucially, prevents condensation from forming on the outside of the cistern, protecting your internal wall structure from damp and rot over time.

Sustainable Power and Easy Access

The Duplo One Compact features a dual flush system that gives you total control over water usage, helping to reduce your environmental impact and utility bills. Despite being hidden behind the wall, maintenance is simple; all internal valves and components are fully accessible simply by removing the flush plate, ensuring your bathroom stays functional without ever needing to disturb your tiles.
