🚚 Delivery in 0–6 weeks · Free consultation
Pa36 concealed toilet mixer with bidet sprayer – Treemme – concealed single-lever toilet mixer with bidet sprayer, holder and hose, on square rosettes – a modern alternative to a bidet.
The Pa36 collection, designed by Danilo Fedeli (3DF), features a body with a perfect 36 mm square cross-section, straight edges and a long, flat spout. A rigorous geometric design for minimalist bathrooms.
What you receive: the external part (lever, holder, bidet sprayer and 1 m hose), in the finish of your choice; 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: lever, 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 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 you need.
