40mm Concealed Single-Lever Washbasin Mixer on Plate

40mm concealed plate-mounted single-lever washbasin mixer – Treemme – concealed stainless steel washbasin mixer, mounted on a 200 × 75 mm plate: curved spout and slim lever. The plate can be mounted horizontally, with the lever to the right or left of the spout, or vertically, with the lever above the spout; the spout can be chosen in 100, 150 or 200 mm.

The 40mm collection reinterprets the classic lever mixer: a 40 mm cylindrical body, curved spout and slim, easy-to-maneuver vertical lever. An essential design, suitable for any bathroom style, made entirely from satin-finished or PVD-coloured AISI 316L stainless steel.

What you receive: the external part (plate, spout and lever), 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 concealed in the wall and has two parts:

• external part – the visible part: lever, plate or rosettes, spout, in the finish of your choice;
• concealed body (code RWIT 51A5 ZZ 01) – the part installed in the wall by the plumber. It is not visible and is the same for all finishes.

The product cannot be installed without the concealed body. From the Set menu, choose:

• External part only – if you already have a Treemme concealed body installed in the wall (for example, if you are replacing a mixer or the plumber has already installed it);
• Complete set with concealed body – for a new installation: you will receive everything you need.

Finishes

Satin-finished stainless steel or one of the three PVD colours: gunmetal, bronze and gold. PVD finishes are applied in a vacuum and are highly resistant to scratches and limescale.

Frequently asked questions

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 a Treemme concealed body installed in the wall.

How is it installed?

Installation is carried out by a plumber. For concealed models, the body is installed in the wall before tiling, and the external part is fitted at the end.

How long does delivery take?

Delivery throughout Romania takes 0–6 weeks, depending on the finish. The displayed prices include VAT.
