Packed with useful features, the Grohtherm smart control concealed thermostat features a minimalist design that will enhance any modern bathroom. The innovative Smart control technology allows you to select your desired spray source and adjust the water volume at the push-turn of a button. The three valves offer total flexibility, whatever your shower set up – you can control, switch between or even combine different spray patterns and water outlets. Integrated Grohe TurboStat technology prevents any unpleasant temperature fluctuations. Grohe easy logic markings and textured buttons with exchangeable symbols make it easy and intuitive to use. Family-friendly, the Grohe SafeStop override button allows you to set a maximum temperature of 100° F/38° C to prevent scalding. Water-saving Grohe EcoJoy technology gives you the option of a reduced flow rate with no compromise on enjoyment, and, thanks to the Grohe's QuickFix system, it’s quick and easy to install . Please note that this product must be installed in combination with the Grohe Rapido Smartbox.
