Our concealed ceramic overflow system, the alternative to standard overflows for washbasins and bidets, has many benefits. Thanks to our overflow system which is invisible from the outside, our washbasins and bidets no longer have a visible overflow hole, which not only improves the appearance of the product, it also makes cleaning much easier. This hygienic and aesthetic innovation is very simple: water rises in a concealed internal channel in parallel with the water inside the washbasin, and overflows into the run-off when the water reaches the maximum level. Another attractive detail of LAUFEN washbasins is the ceramic cover on the pop-up waste, which is available in a variety of glazes. These covers are available with a wide range of pop-up waste versions for many washbasins and bidets (e.g. the ILBAGNOALESSI One and the dOt, PALOMBA COLLECTION, Lb3, mimo, and others).
