Ios Concealed Bath/Shower Mixer with Diverter and Hand Shower
🚚 Delivery in 0–6 weeks · Free consultation
Ios concealed bath/shower mixer with hand shower – Treemme – concealed mixer with fluted handle, diverter and hand shower with holder, on three square rosettes. The diverter directs water to the hand shower or to a shower head or bath spout (sold separately).
The Ios collection, designed by Marco Pisati and Giampiero Castagnoli, is inspired by the fluted columns of Greek temples: square body, flat fluted handle and waterfall spout. A luxurious sculpture for contemporary bathrooms.
What you receive: the external part (rosettes, handle, diverter, hand shower holder and 1.5 m hose), in the chosen 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, spout, in the chosen finish;
- concealed body (code RWIT 51D9 ZZ 01) – 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.

Frequently asked questions
Is the shower head included?
No. The second outlet can be connected to a Treemme shower head (wall or ceiling-mounted) or the Ios bath spout.
Do I need the concealed body?
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.
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.
