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.
Which height should I choose?
The 106 mm version is suitable for classic basins (with a longer spout for deep basins), the 166 mm version for taller basins, and the 246 mm version for countertop bowl basins.
How is it installed?
Installation is standard and is carried out by a plumber.
How long does delivery take?
Delivery throughout Romania takes 0–6 weeks, depending on the finish. The displayed prices include VAT.
