Treemme stainless steel concealed thermostat for temperature control – Treemme – concealed thermostat on a square stainless steel plate, which controls only the water temperature: it is combined with separate stop valves or diverters, for showers with multiple individually controlled outlets.

What you receive: the exterior part (plate and thermostatic handle), in the chosen model and finish; the concealed body only if you choose the complete set.
Exterior part or complete set?
This product is wall-mounted and has two parts:
- exterior part – what is visible: handle, plate or rosettes, pipe, in the chosen finish;
- concealed body (code RWIT 51A8 ZZ 03 / RWIT 7286 ZZ 70) – 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:
- Exterior part only – if you already have the Treemme concealed body installed in the wall (for example, you are replacing a faucet or the plumber has already installed it);
- Complete set with concealed body – for a new installation: you receive everything that is necessary.

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 water pressure or temperature in the network changes, for a comfortable and safe shower.
Do I need the concealed body?
Yes, for a new installation it is mandatory. Choose “Complete set with concealed body”. The “Exterior 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 the tiles, and the exterior 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.
