Materials from nature engender a blissful atmosphere and with their natural colours and patterns they present a sophisticated highlight in the distinctive home. This is why the owners of a Düsseldorf residence decided to use marble for the installation of their bathroom and the adjacent guest WC. Here both the wall and the floor were to be faced and new bathroom equipment made with the natural material. Consulting with the architect, the residents settled on two different types of marble. For a total of 28.7 m² wall area in both rooms and for the double washbowl in the bathroom and the hand washbasin in the guest WC, they selected a light Covelano marble. The floor with a size of 16.45 m² was to be covered with dark Etruscan Fossil from Tunisia throughout.
