The wall-hung Geberit ONE WC ceramic appliance is the first WC with a newly developed fastening element in the hollow space at the rear of the ceramic appliance for anchoring to the wall. It makes it possible to mount the toilet at a different height – both during the initial installation as well as many years down the road. The range here is a total of 4 cm (from +3 cm to -1 cm vis-à-vis the factory setting), which can have a decisive impact on the sitting comfort. The interior of the rimless WC ceramic appliance is a development of the TurboFlush flush technology. Thanks to the optimised way in which the flow of water is guided, the flush is not just very quiet, but also extremely thorough. The ceramic surface of the WC ceramic appliance with the high-quality Geberit KeraTect® special glaze is completely accessible and can be cleaned with a minimum of effort and water consumption.
