Kea Concealed Thermostatic Shower Mixer, 1 Outlet
🚚 Delivery in 0–6 weeks · Free consultation
Kea concealed thermostatic shower mixer with one outlet – Treemme – concealed thermostatic mixer on a vertical plate, with one outlet: the thermostat maintains a constant water temperature, while the Kea controls operate a single outlet (for example, a shower head).
What you receive: the external part (plate, thermostat handle and controls), in the finish and with the handles of your choice; the concealed body only if you choose the complete set.
External part or complete set?
This mixer is wall-mounted and has two parts:
- external part – what is visible: the handles, rosettes, pipe, in the finish of your choice;
- concealed body (code RWIT 7287 ZZ 30) – 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 mixer 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 mixer or the plumber has already installed it);
- Complete set with concealed body – for a new installation: you receive everything required.
Finishes
10 finishes, from classic chrome to brushed gold and rose gold. PVD finishes are highly resistant to scratches and limescale.

Handles
Kea handles can be made of brass (in the same finish as the mixer), natural marble (Avorio Segesta, Portoro, Red Jasper, Verde Ming), or crystal (clear or black). Each marble handle is unique, with natural veining.

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.
What does the thermostat do?
It maintains the set water temperature, even if the mains water pressure or temperature changes.
