22mm Concealed Bath/Shower Mixer with Spout and Hand Shower

22mm concealed bath-shower mixer with spout and hand shower – Treemme – concealed set for stainless steel bath: wall-mounted spout, knurled single-lever handle, diverter and hand shower with holder, each on its own round Ø 60 mm rosette.

The 22mm collection, designed by Marco Fagioli, Emanuel Gargano and Giampiero Castagnoli, is based on a 22 mm diameter stainless steel tube: curved pipes with clean lines and knurled cylindrical handles, with a fine texture that provides a secure grip even with wet hands. It is made entirely from satin-finished or PVD-coloured AISI 316L stainless steel.

What you receive: the complete external part (spout, controls, hand shower with hose and holder), in the chosen finish; the concealed body only if you choose the complete set.

External part or complete set?

This product is wall-mounted and has two parts:

• external part – what is visible: handle, plate or rosettes, spout, in the chosen finish;
• concealed body (code RWIT 6005 IS 50) – the part that is built into the wall by the plumber. It is not visible and is the same for all finishes.

Without the concealed body, the product cannot be installed. From the Set menu, choose:

• External part only – if you already have the Treemme concealed body installed in the wall (for example, if you are replacing a mixer or the plumber has already installed it);
• Complete set with concealed body – for a new installation: you receive everything you need.

Finishes

Satin stainless steel or one of the three PVD colours: gun metal, bronze and gold. PVD finishes are applied in a vacuum and are highly resistant to scratches and limescale.

Frequently asked questions

What do the knurled handles mean?

The 22mm cylindrical handles have a fine texture engraved in the steel, which makes them pleasant to touch and easy to turn even with wet hands or soapy hands.

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.

Do I need the concealed body?

Yes, it is mandatory for a new installation. Choose “Complete set with concealed body”. The “External part only” option is only for those who already have the Treemme concealed body installed in the wall.

How is it installed?

Installation is carried out by a plumber. For concealed models, the body is built into the wall before tiling, and the external part is installed at the end.

How long does delivery take?

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