🚚 Delivery in 0–6 weeks · Free consultation
X-Change concealed bath mixer with spout and hand shower – Treemme – complete concealed bath mixer: handle, diverter, bath spout and hand shower with holder, on a single plate or on separate round rosettes.
The Treemme X-Change collection is built from pure cylindrical shapes: slim bodies, curved spouts and fine handles, in a single-lever or two-tap version. An essential design, easy to combine, for contemporary bathrooms.
What you receive: the external part (plate or rosettes, handle, diverter, spout, hand shower with holder and hose), in the chosen model and 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 51D7 ZZ 12) – 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 that is necessary.
