Spare parts for the Grohe 34771000 Grohtherm 800 Cosmopolitan thermostatic bar shower mixer. This exposed wall-mounted mixer uses separate temperature and water flow controls and is designed around serviceable internal cartridges, seals, non-return valves and control components.
The mixer uses the 47885000 thermostatic cartridge for temperature regulation and the 45346000 ceramic flow cartridge for water shut-off and flow control. These Grohe spare parts allow individual worn components to be serviced without replacing the complete mixer where the valve body remains in suitable condition.
Function and Servicing
The thermostatic control regulates the mixed-water temperature while the separate ceramic headpart controls the on/off water flow. The temperature control incorporates a 38C SafeStop point, while the mixer also uses non-return valves and strainers within the inlet arrangement.
A worn flow shut-off cartridge can cause water to continue dripping from the shower head when the mixer is turned off. Temperature instability, difficulty maintaining the selected temperature or restricted temperature adjustment can indicate a problem within the thermostatic control components.

Before you order check
Before you order check that the mixer is marked 34771000 and identify which component requires replacement. The 47885000 is the standard thermostatic cartridge associated with this mixer, while the 47175000 reverse TurboStat cartridge is an optional reverse-supply component and should not be ordered as the standard thermostat without confirming the installation requirements.
