What you receive: the external part (plate or rosettes, thermostatic lever and diverter knob), 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 – the visible part: lever, plate or rosettes, pipe, in the chosen finish;
• concealed body (code RWIT 22A2 ZZ 01) – the part 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 faucet or the plumber has already installed it);
• Complete set with concealed body – for a new installation: you receive everything you need.

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.

What does the thermostat do?

It maintains the set water temperature, even if the mains water pressure or temperature changes, for a comfortable and safe shower.

What does 2 or 3 outlets mean?

The diverter directs water to each outlet in turn: for example, the shower head and hand shower (2 outlets) or the shower head, hand shower and side jets or bath spout (3 outlets). Choose the number of outlets from the menu.

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.
