“Diana Spin” reduces its formal design to the essential mechanical functions of rotating and lifting. The hinge facilitates an aperture angle of 90°, both inwards and outwards. The door lifts when it is opened and lowers when it is closed, creating a tight seal. The hinge is mounted using a flush interior system. “Diana Spin” is the base module for the configuration of several types of shower cabins. The hinge requires a staggered cut, visualizing a high degree of independence.
