Optical illusion or bathroom sink? This almost invisible bathroom sink was created by Bulgarian designer Victor Vasilev, who currently lives in Milan, Italy. The Kub basin is an exceptional example of minimal industrial design. Created in 2010 by Victor Vasilev, the Kub basin features a unique sleek design, which is defined by clean geometric shapes and lines combined together in a discreet luxurious composition. The Kub basin impresses with the choice of glass for the main basin, a material that makes it look almost invisible. The project is also available in a highly intriguing version for two. The carrara stone can be cleverly used as storage space, blending its aesthetics with a high dose of function.
