Q30 Concealed Washbasin Mixer, Separate Plates

Q30 concealed washbasin mixer with separate plates – Treemme – concealed washbasin mixer with spout and handle on two separate square plates. An architectural look, with the countertop completely free.

The Q30 collection features square, pure lines and a blade-thin spout: a minimalist Italian design by Giampiero Castagnoli and Marco Pisati, created for modern bathrooms.

What you receive: the external part (the two plates, spout and handle), in the model and finish of your choice; the concealed body only if you choose the complete set.

External part or complete set?

This product is concealed in the wall and has two parts:

• external part – what is visible: handle, plate or rosettes, spout, in the finish of your choice;
• concealed body (code RWIT 51A5 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 a Treemme concealed body installed in the wall (for example, if 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

Which spout length should I choose?

The short spout (185–190 mm) is suitable for smaller washbasins, while the 220 mm spout is suitable for deeper washbasins or countertop basins.

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 wall.

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.
