28mm Stainless Steel Single-Lever Bidet Mixer

28mm stainless steel single-lever bidet mixer – Treemme – single-lever stainless steel bidet mixer with a cylindrical column and 28mm horizontal spout, with a swivelling aerator.

The 28mm collection, designed by Giampiero Castagnoli and Marco Pisati, is constructed from 28mm stainless steel tubes joined at a right angle: a diagonally cut horizontal spout and a vertical cylinder that also serves as the control. It is made entirely from AISI 316L stainless steel, satin-finished or in PVD colours.

What you receive: the mixer with flexible connections, in the model and finish of your choice (the waste valve is ordered separately).

Frequently asked questions

What does the "with pin" version mean?

The 28mm control is a rotating cylinder. The standard version has a smooth cylinder; the version with a pin has a small side pin, making it easier to handle. Both are shown in the photographs.

Why stainless steel?

AISI 316L stainless steel is the same steel used in the food and shipbuilding industries: it does not rust, does not release metals into the water, and is resistant to limescale and cleaning products. PVD finishes are applied in a vacuum and are highly resistant to scratches.

How is it installed?

Installation is standard and is carried out by a plumber.

How long does delivery take?

Delivery throughout Romania takes 0–6 weeks, depending on the finish. The prices shown include VAT.
