Ios Floor-Standing Washbasin Mixer
🚚 Delivery in 0–6 weeks · Free consultation
Ios Floor-Mounted Basin Tap – Treemme – single-lever column basin tap, floor-mounted, for freestanding basins or basins placed in the center of the bathroom. Height: 1090 mm.
The Ios collection, designed by Marco Pisati and Giampiero Castagnoli, is inspired by the fluted columns of Greek temples: square body, flat handle with fine grooves, and spout with a waterfall jet. A luxurious sculpture for contemporary bathrooms.
What you receive: the column with the tap and floor rosette, in the chosen finish; the concealed floor-mounted part only if you choose the complete set.
External part or complete set?
This product is floor-mounted and has two parts:
- external part – what is visible: handle, plate or rosettes, spout, in the chosen finish;
- concealed body (code RWIT 4A62 ZZ 50) – the part that is fixed in the floor screed 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 floor (for example, you are replacing a tap or the plumber has already installed it);
- Complete set with concealed body – for a new installation: you receive everything that is necessary.
Finishes
10 finishes, from classic chrome to matte black, gold and brushed rose gold. PVD finishes are highly resistant to scratches and limescale.

Frequently asked questions
What is the concealed floor-mounted part?
Floor-mounted taps are fixed to a concealed part in the screed (code RWIT 4A62 ZZ 50), which brings hot and cold water. The “Complete set” option includes it.
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 floor.
How is it installed?
Installation is carried out by a plumber. For concealed models, the concealed part is fixed in the floor before tiling, and the external part is installed at the end.
