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 chosen finish;
- 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 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.
