5mm, signed by Giampiero Castagnoli, Emanuel Gargano and Marco Fagioli, is among the most successful lines of Rubinetterie Treemme.
The 5mm design expresses the essential characteristics of the technology that generated it. Five millimetres is the thickness of the confuit in which water passes up to the outlet.
The use of a single thickness for all the components of the tap make the design of 5mm light.
