Treemme Rubinetterie

Four decades after it was founded, Treemme Rubinetterie continues to propose new collections ranging from traditional to more innovative lines, while preserving those characteristics that have allowed it to flourish and prosper: high quality and impeccable service.

The company prioritizes the origin of its products, carefully selecting its suppliers in Italy and carrying out 80% of production in-house. The products best respond to customers’ needs by virtue of being entirely made in Italy.


The Treemme Rubinetterie company, originally called “Rubinetterie Toscane 3M” to sum up in a few words its very essence, was founded in Asciano, in the province of Siena: the company was set up by 3 founder members (Renato Michelangioli, Armando Medina and Guido Mencarelli) – whose surnames just so happened to share the same initial - it is located in Tuscany and, last but not least, produces taps and fittings. The company started out as a crafts workshop specialized in the entire tap production process (casting, galvanics, polishing, finishing and assembly) and quickly evolved due to outstanding organization that was to seal its success from day one. Consumers were to soon recognize and appreciate the meticulous approach to quality and customer service.

the company launched its product range in colour thanks to valuable collaboration with the DESIGN CALONACI & GAZZEI studio that devised the Arcobaleno (Rainbow) collection.

during its internationalization phase, the company changed its name to Rubinetterie 3M (without the word “toscane”) – and later to Treemme Rubinetterie – in order to gain ground not only in Italy but also overseas.

The Treemme Rubinetterie company has recently also been extremely successful in the field of design, focusing more on the personalization and innovation of its products without however neglecting its classic and more traditional lines. Well-known design studios were given the task to develop new forms and ideas such as: architect Missanelli for QUADRA, the American designer Remi Theberg for BRIDGE, and the G. Vegni Design studio for the more recent CUT, PAO and BLOK lines; the latter was awarded the prestigious DESIGN PLUS 2007 prize at the ISH fair in Frankfurt. The DESIGN PLUS award was won not only in 2007 but also in 2011 with Philo designed by Gianluca Belli / Phi Cube and with Light by Danilo Fedeli, in 2013 instead the new protagonist is the project called 5mm by Ocostudio and ing.Castagnoli.
