Silvia is ergonomically designed, so that it corresponds to human shape and is wider in shoulders and gets narrower towards feet. This shape also brings substantial reduction in water use, from 280 to 130 liters. The overflow integrated in a thin wall is an innovative solution that so far has not been applied in mass production. The bathtub is made of cast marble, with natural dolomite powder as its main ingredient. Thus, it absorbs warmth and ensures comfort of use.
