Minimalistic design with ergonomic metal handle. Offering quality, technology and design at a competitive price, Grohtherm 1000 Cosmopolitan is our most compact thermostat. Crafted from a series of perfect cylinders, its slender design is the preferred choice for modern, architectural-style spaces. Purity meets performance - a subtle rim on the cylindric metal handle increases grip, even when operated with wet, soapy hands.
