3.6 Concealed Shower Mixer with 2- or 3-Outlet Diverter

3.6 concealed shower mixer, with 2 or 3 outlets – Treemme – concealed single-lever stainless steel shower mixer, with a round diverter for 2 or 3 outlets: on a vertical plate or on two separate round rosettes. A simple version with a single outlet is also available.

The 3.6 & 3.6+ collection, designed by Giampiero Castagnoli, features a tapered cylindrical stainless steel body and a flat, ruler-thin spout. It is available in two versions: 3.6, with a flat, horizontal lever, and 3.6+, with a cylindrical lever that continues the line of the body. It is made entirely of AISI 316L stainless steel, which does not rust and is resistant to limescale.

What you receive: the external part (plate or rosettes, lever and diverter button), 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: lever, plate or rosettes, spout, in the chosen finish;
• concealed body (code RWIT 22A2 ZZ 01 / RWIT 51A8 ZZ 03) – 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.

Finishes

Satin stainless steel or one of the six PVD colors: 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

What is the difference between 3.6 and 3.6+?

The body and spout are the same; the lever is different. On the 3.6, the lever is flat and horizontal, like a blade, while on the 3.6+, the lever is cylindrical and continues the line of the body.

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.

What does 2 or 3 outlets mean?

The diverter directs water one at a time to each outlet: 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 from the 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 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 tiling, 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.
