Mercury is a thermostatically controlled shower system with three water outlets and a temperature display. The rotary knob with its luminous display provides a striking contrast to the control unit's clear and geometric shape. The digital display is powered by a hydroelectric power generator. The shower outlet features a bubble-mix function, which reduces water consumption by around one third. The glass panel on the top serves as a shelf for shower utensils. “Mercury impresses us with restrained, elegant design that integrates effortlessly into modern bathroom interiors,” the jury explained.
