Super, the AISI316L stainless steel bathroom collection designed by Calvi Brambilla. The 'Squircle' or 'Supercircle' shape provides a more generous hand resting surface than a circle, without the harshness of the 90° angles of a square. In their own words “We started with the search for a shape that would allow the knob to be easily gripped with the hand, hence an ergonomic design, but that would not look like an object simply drawn according to its function.

The squircle is a geometric figure that we love because it looks like it was drawn freehand but is governed by a mathematical function: not surprisingly, it is a shape that is widely used in the design of physical interfaces such as keyboards. Stainless steel is an extraordinary material in terms of its durability and appearance, but it poses many technical limits in the creation of free forms. In designing Super, therefore, we started precisely from an analysis of the technical constraints in order to delimit the field of action within which we could move. Once we had identified the squircle as a design and a figure, we adapted the theme in all variants necessary to build a coherent family.

The minimalism and aesthetic cleanliness that characterises QuadroDesign products also had to be reflected in our series and so there was a long process of refining the details conducted side by side with the technical department.” QuadroDesign is one of the first Italian companies to use this stainless steel for faucets instead of brass, since 2001.
