Exposed thermostatic bath and shower mixer valve with SafeStop temperature limiter, EcoJoy water saving, and chrome finish for safe, efficient bathing.
The Grohe Grohtherm 1000 Cosmopolitan is one of the most widely fitted exposed thermostatic shower mixers in the UK. The TurboStat cartridge responds to pressure and temperature changes in fractions of a second, maintaining the selected shower temperature even when other taps or appliances draw water elsewhere in the house. The SafeStop button at 38 degrees provides scald protection, which is particularly important in family bathrooms.
Thermostatic shower valves are now considered essential in UK bathrooms, providing both comfort and safety. The Grohe Grohtherm 1000 Cosmopolitan has become a benchmark product in this category, combining reliable thermostatic control with straightforward installation.
The TurboStat thermostatic cartridge is Grohe’s proprietary technology for maintaining water temperature. Unlike basic thermostatic cartridges that react slowly to pressure changes, the TurboStat element responds almost instantly. When someone flushes a toilet or runs a tap elsewhere in the house, the change in supply pressure that would cause a temperature spike or drop in other valves is corrected in fractions of a second.
The SafeStop button acts as a physical limit on the temperature control, preventing the valve from being turned beyond 38 degrees Celsius without deliberately overriding the stop. This is a genuine safety feature in family bathrooms where young children use the shower or bath. The override is simple for adults but prevents accidental scalding.
The Grohe Grohtherm 1000 Cosmopolitan is the thermostatic mixer valve that plumbers recommend with confidence. The TurboStat technology delivers measurably better temperature stability than budget alternatives, and the SafeStop safety feature makes it the right choice for any household.
