By fully controlling the wash-down water, Serel has found a solution to wash out the inner surface of the bowl, cleaning the channel section efficiently and preventing splashing. Luvi has been designed based on the concept of maximum cleanliness. The physical features of the design prioritise the flow system (bowl structure), surface technology, compatible water closet cover and cleanliness. With 4,5 lt, it saves 25% water in full function and prevents dirt and bacteria growth and allows an easy cleaning with its Hygiene+ surface technology. The cover of the closet is easy to assemble and reassemble and closes smoothly and quietly.
