Q30 Concealed Thermostatic Shower Mixer with 2- or 3-Outlet Diverter

Q30 concealed thermostatic shower mixer with 2 or 3-way diverter – Treemme – concealed thermostatic shower mixer with temperature selector and rotary diverter for 2 or 3 outlets, on a single vertical plate.

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

What you receive: the external part (plate, thermostat and diverter), in your 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 you see: handle, plate or rosettes, spout, in your chosen finish;
• concealed body (code RWIT 8A46 ZZ 20) – the part installed inside the wall by the plumber. It is not visible and is the same for all finishes.

The product cannot be installed without the concealed body. 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 will receive everything you need.

Frequently asked questions

What does the thermostat do?

It maintains the set water temperature, even if the mains water pressure or temperature changes, for a comfortable and safe shower.

What does 2 or 3 outlets mean?

The diverter directs water to each outlet one at a time: for example, the shower head and hand shower (2 outlets) or the shower head, hand shower and side jets or bath spout (3 outlets). Choose the number of outlets in the Outlets menu.

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.

How is it installed?

Installation is carried out by a plumber. For concealed models, the body is installed inside the wall before tiling, and the external part is fitted at the end.
