In Chinese philosophy, yin and yang stand for opposing forces, which complement one another as an inseparable entity. The washbasin by the same name picks up on this idea and creates a harmonious appearance with high-contrast colours and shapes: the white, oval washbasin with its round inner basin is embedded in a rectangular, black panel. A narrow edge in the basin quickly directs the water into the overflow if necessary. The generous storage area offers space for cosmetics.
