The free-standing bath tub is cast in a single piece from high-quality mineral material. The material expresses the products longevity and high quality through its stone-like look and feel. The underlying formal idea focuses on straight lines. In the interior, too, clear yet soft contours dominate. One distinctive feature is the way the tub opens out towards the top in a chalice shape, which, despite the thinness of the material, provides for a wide rim and creates an inviting gesture. The end of the overhang itself is defined by a very distinct outer edge, providing a clear separation between the bath tub interior and exterior.
