As our gauge when constructing GROHE thermostats we used the most sensitive thermometer around – your skin. The revolutionary thermostats in our Grohtherm range ensure that hot and cold water will touch your skin in exactly the proportions you desire. GROHE TurboStat® is a revolutionary technical feature – it provides the correct shower temperature in seconds and keeps it constant. The many elegant design features in these miniature technological marvels are wonderfully innovative.
