Ios Floor-Standing Bath Mixer with Hand Shower
🚚 Delivery in 0–6 weeks · Free consultation
Ios Floor-Mounted Bathtub Mixer with Hand Shower – Treemme – Ios floor-mounted single-lever column bath mixer, with spout, diverter and hand shower.
The Ios collection, designed by Marco Pisati and Giampiero Castagnoli, is inspired by the fluted columns of ancient Greek temples: a square body, a flat handle with fine fluting and a waterfall spout. A luxurious sculpture for contemporary bathrooms.
What you receive: the column with mixer, spout, hand shower and 1.5 m hose, in your 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 – the visible part: handle, plate or rosettes, spout, in your chosen finish;
- concealed body (code RWIT 4A62 ZZ 50) – the part that is fixed in the floor screed by the installer. 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 a Treemme concealed body installed in the floor (for example, if you are replacing a mixer or the installer has already installed it);
- Complete set with concealed body – for a new installation: you receive everything you need.
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 mixers are fixed to a concealed part installed in the floor screed (code RWIT 4A62 ZZ 50), which supplies 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 a Treemme concealed body installed in the floor.
How is it installed?
Installation is carried out by a professional installer. For concealed models, the concealed part is fixed in the floor before tiling, and the external part is installed at the end.
