The open design of the flushing rim enables an innovative water flow. Thanks to modern 4.5 litre technology, perfect flushing results are guaranteed, even with only a small amount of water. Due to its open and easily accessible rim area, it is also considerably easier to keep the bowl clean. With its new Rimless technology, Duravit demonstrates how geometry, fluid mechanics and design can be successfully combined for maximum efficiency. In Duravit Rimless, the open design of the WC rim enables an innovative and powerful flush: water flows in the form of a horizontal arc, and then vertically, before flushing the entire inner surface of the bowl without splashing.
