The Future of Concealed Performance: Where Advanced Technology Meets Architectural Freedom.

The ROCA Duplo S Under Window Cistern system is the definitive problem solver for back-to-wall (BTW) toilets positioned in height restricted areas, such as beneath windows or within low level furniture units. Standing at a compact 600mm tall, it allows you to hide the complexities of your plumbing behind the wall.

Silence and Control

Engineered for quiet operation, the system functions at less than 20 dB(A) to ensure your bathroom remains as peaceful as possible. Furthermore, the unit is fully insulated to prevent condensation, protecting your internal wall structure and furniture from moisture while dampening the sound of the refill.

Key Features

• Under Window Specialist Height: At just 600mm, it is perfectly suited for installations where vertical space is restricted.
• Dual Mount Flush Flexibility: Designed for either front or top flush plate mounting to suit your cabinetry or wall design.
• Water Conservation: Dual-flush volumes of 6/3 litres.
• Quiet Operation: Engineered to operate at less than 20 dB(A) for ultimate acoustic comfort.
• Thermal & Acoustic Shield: High density insulation prevents condensation and dampens noise.
