40mm Concealed Timed Mixer with Automatic Shut-Off

40mm timed concealed bath/shower mixer with automatic shut-off – Treemme – concealed stainless steel mixer with timed automatic shut-off: press the button and water flows for between 18 and 30 seconds, then stops automatically. Ideal for hotels, gyms and public spaces, for washbasins or showers, single-outlet or with a diverter for 2 outlets.

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

What you receive: the external part (rosette or control rosettes), in the model and finish of your choice; 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: lever, plate or rosettes, pipe, in the finish of your choice;
• concealed body (code RWIT 22A2 ZZ 01 / RWIT 51A8 ZZ 03) – 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 a 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: gunmetal, 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.

How does the timing work?

When pressed, the timed cartridge allows water to flow for a factory-set time (between 18 and 30 seconds) and then stops it automatically, eliminating the risk of waste.

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 a 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 fitted at the end.

How long does delivery take?

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