The Rubinetterie Treemme story began in 1968, in Asciano, in the province of Siena.
The original name was “Rubinetterie Toscane 3M”, with 3M referring to the surnames of the three founding partners (Renato Michelangioli, Armando Medina and Guido Mencarelli), who all happened to share the same initial. 

This new Tuscan company focused immediately on the production of taps.
The entire production cycle of the taps - composed of casting, galvanic coating, polishing, electroplating and assembly - was carried out in the company’s craft workshop.
The impressive workflow organisation implemented from day one allowed the business to grow rapidly, and the market was quick to acknowledge and appreciate the painstaking attention paid to quality and customer service.

1980 saw the start of the process that was to earn Rubinetterie Treemme recognition as an interior design brand, introducing colour to the sector with the launch of the “Arcobaleno” collection, featuring knobs in a variety of hues.

At the end of the 1980s, with stable growth now established beyond the domestic market, the company name became Rubinetterie 3M, before being further changed to Rubinetterie Treemme, as it is known today.
