GROHE thermostatic temperature control valves ensure a maximum of bathing safety for everyone, but are particularly important for small children, physically disabled people, and elderly people. Due to GROHE Turbo Stat technology, our GROHE thermostatic valves are accurate to within 1 degrees Fahrenheit. Enjoy the perfect bath or shower by simply dialing your desired water temperature. A high-flow GROHE thermostat rough valve is perfectly suited and preferred for meeting the demands of large multiple-head custom shower systems. But GROHE thermostats, however, are not just muscle. They are available with a wide selection of trim options in multiple finishes to match or compliment GROHE faucet and shower designs.
