For when the everyday will just not do, choose the Grohe Grohtherm XL Central Thermostat not only for its forward-thinking looks but for its long lasting, world renowned Grohe engineering. A thermostatic mixing valve senses temperature fluctuations and automatically remixes the hot and cold water to keep your shower temperature safe, consistent and comfortable without a change in water pressure.
Featuring Grohe exclusive StarLight plating technology.
Starting with their unique StarLight plating process, Grohe sub-plates layers of copper or nickel, depending on the surface, to ensure a flawless non-porous base for their dazzling finish layer. StarLight ensures a luminous mirror-like sheen that is resistant to scratches and tarnishing for years of stunning, trouble-free use.
