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 chosen finish;
• concealed body (code RWIT 7582 .. 02, in the same finish) – the part that is built into the wall by the plumber. In this model, part of the body remains visible, which is why it is supplied in the same finish.

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.

Frequently asked questions

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.

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.

Why does the concealed body also have a finish?

On the COAX thermostat, part of the concealed body remains visible around the lever, which is why it is supplied in the same finish as the external part. The price of the complete set includes the body in the chosen finish.

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.
