🚚 Delivery in 0–6 weeks · Free consultation
Appia concealed thermostatic shower mixer with separate rosettes, 2 or 3 outlets – Treemme – concealed thermostat with temperature selector and controls for 2 or 3 outlets, each on its own round rosette of Ø 115 mm.
The Appia collection, designed by Danilo Fedeli (3DF), features a tall, curved spout and faceted handles reminiscent of ancient columns: a sculptural, elegant design that is both classic and contemporary.
What you receive: the external part (rosettes, temperature selector and controls), 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: handle, plate or rosettes, spout, in the finish of your choice;
- concealed body (code RWIT 7274 ZZ 40 / RWIT 7275 ZZ 40) – 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 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 you need.

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.
