Nanotech Concealed Single-Lever Mixer with Separate Control
🚚 Delivery in 0–6 weeks · Free consultation
Nanotech concealed single-lever mixer with separate control – Treemme – concealed single-lever mixer with a single outlet: the cylindrical lever sits on a separate square rosette. It can be combined with the Nanotech wall-mounted spout for a washbasin or bath, or with a shower set.
The Nanotech collection, designed by Phicubo (Alessandra Bertini and Gianluca Belli), features a compact cylindrical body and a flat, blade-like spout that emerges directly from the body. A technical and elegant design with matte black accents on the shower accessories.
What you receive: the external part (rosette and lever), in the chosen finish; the concealed body only if you choose the complete set. The spout is ordered separately.
External part or complete set?
This product is wall-mounted and has two parts:
- external part – what is visible: the lever, plate or rosettes, spout, in the chosen finish;
- concealed body (code RWIT 51A8 ZZ 03) – 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, 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.
