Geberit WC Frame for Wall hung WC with Odour Extraction - 112cm - Front Operated

Pleasant-smelling. Fresh air installed.
Your bathroom is an oasis of well-being that you want to enjoy with all your senses, whether you are relaxing in the bath or using the toilet. The innovative Geberit DuoFresh WC system offers you an ideal solution for bringing fresh air into the area around the WC. Odours are extracted from right inside the ceramic unit, purified and gently released again. You won’t be the only one who is pleasantly surprised by the subtle sense of freshness.

Direct odour extraction
The new Geberit DuoFresh WC system brings a breath of fresh air to the bathroom. The secret lies hidden behind the wall. A switch on the flush plate activates the odour extraction system, which purifies the air using the active carbon filter and releases it back out into the room. This solution does not just cover up odours like an air freshener, or spread them around the room first like conventional bathroom ventilation systems.

With Geberit Duofresh everything you need to bring fresh air into the area around your WC is hidden into the wall.

  • Unpleasant odours are extracted right at their source
  • Discreet look thanks to the integration of the odour extraction unit into the concealed cistern
  • Maximum ease of use
  • Quick and easy replacement of the active carbon filter (approx every 12 months)
  • Integrated insert for in-cistern blocks
  • Energy savings compared to ventilation through a window

Please note:
Only extracts odours when used in conjunction with Sigma40 flush plates.
Compatible with all other Sigma flush plates for standard use.
