40mm Concealed Bath/Shower Mixer with Hand Shower

40mm concealed bath-shower mixer with hand shower – Treemme – concealed stainless steel set for bath or shower: single-lever mixer with slim handle, diverter, hand shower with holder and, for bath versions, a 40mm spout. On a long plate or separate round rosettes.

The 40mm collection reinterprets the classic lever mixer: a 40 mm cylindrical body, curved pipes and a slim, vertical handle that is easy to operate. An essential line, suitable for any bathroom style, made entirely from AISI 316L stainless steel, satin or in PVD colours.

What you receive: the complete external part (plate or rosettes, controls, spout where applicable, hand shower with hose and holder), in the chosen model and 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 51D7 ZZ 12 / RWIT 51D9 ZZ 01) – 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, 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

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.
