Hask concealed thermostatic shower mixer, separate plates, 2 or 3 outlets – Treemme – modular concealed thermostat, with temperature selector and individual outlet controls on separate square plates, 105 mm: for 2 or 3 outlets, with an airy look on the shower wall.
The Hask collection, designed by Danilo Fedeli (3DF), features a square-section body with soft edges, a long, slender pipe, and a flat, slightly angled handle. An architectural design, also available in rare finishes such as oxidized or brushed bronze.
What you receive: the external part (plates, temperature selector and controls), 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 – what is visible: handle, plate or rosettes, pipe, in the chosen finish;
- concealed body (code RWIT 7274 ZZ 40 / RWIT 7275 ZZ 40) – the part installed in 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 needed.
