Ios Concealed Single-Lever Mixer with Separate Control
🚚 Delivery in 0–6 weeks · Free consultation
Ios concealed single-lever faucet with separate spout – Treemme – concealed single-lever faucet with a single outlet: the fluted handle sits on a square rosette, separate from the spout. It can be combined with the Ios wall-mounted spout for a washbasin or with a shower set.
The Ios collection, designed by Marco Pisati and Giampiero Castagnoli, is inspired by the fluted columns of Greek temples: a square body, a flat handle with fine fluting, and a spout with a waterfall jet. A luxurious sculpture for contemporary bathrooms.
What you receive: the external part (rosette and handle), in the finish of your choice; 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 handle, plate or rosettes, spout, in the finish of your choice;
- 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, if you are replacing a faucet or the plumber has already installed it);
- Complete set with concealed body – for a new installation: you receive everything you need.
