Bliss Concealed Shut-Off Valve and Diverter
🚚 Delivery in 0–6 weeks · Free consultation
Concealed Bliss stop valve and diverter – Treemme – concealed stainless steel stop valves and diverters with a cross handle on a round rosette: to separately order a wall-mounted spout or the outlets for a thermostatic shower.
The Bliss collection, designed by Annabella Hevesi, reinterprets the classic cross-handle tap in a fluid and sensual form: the soft arms of the handles, the conical bases and curved pipes appear to be shaped from a single flow of metal. It is made entirely from AISI 316L stainless steel, satin-finished or in warm PVD colours.
What you receive: the external part (rosette 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 wall-mounted and has two parts:
- external part – what is visible: handle, plate or rosettes, pipe, in the finish of your choice;
- concealed body (code RWIT 4540 ZZ 01 / RWIT 72B6 ZZ 01 / RWIT 7AD5 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, if you are replacing a tap or the plumber has already installed it);
- Complete set with concealed body – for a new installation: you receive everything that is necessary.
Finishes
Satin stainless steel or one of the six PVD colours: gun metal, bronze, gold, light bronze, chocolate and champagne. PVD finishes are applied in a vacuum and are highly resistant to scratches and limescale.

Frequently asked questions
How do cross handles work?
Like a classic tap: one handle for hot water and one for cold water, which you turn to control the flow and temperature. Ceramic cartridges ensure smooth operation and long-lasting sealing.
Why stainless steel?
AISI 316L stainless steel is the same steel used in the food and shipbuilding industries: it does not rust, does not release metals into the water and is resistant to limescale and cleaning products. PVD finishes are applied in a vacuum and are highly resistant to scratches.
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 the Treemme concealed body installed in the wall.
How is it installed?
Installation is carried out by a plumber. For concealed models, the body is built into the wall before the tiles are fitted, and the external part is installed at the end.
How long does delivery take?
Delivery throughout Romania takes 0–6 weeks, depending on the finish. The displayed prices include VAT.
