## Long description

GROHE Grohtherm 800 thermostatic shower valve with 1/2 inch connections delivers precise temperature regulation for shower installations. The unit is built around a thermostatic control cartridge that maintains a stable outlet temperature even when inlet pressure or flow fluctuates. Designed for domestic and light commercial bathrooms, the valve reduces the risk of scalding and improves user comfort while integrating with standard 1/2 inch plumbing.
Advantages
The thermostatic control cartridge ensures continuous temperature stability and quick adjustment to set temperature. Compact 1/2 inch connections allow straightforward retrofit or new-install integration with common shower plumbing. The design reduces thermal shock from sudden cold or hot water changes and contributes to safer showering for all ages. The valve's reliable control mechanism minimises the need for frequent manual corrections and supports consistent performance under varying water conditions.
Suitable for
 Residential shower installations
 Small hotels, guesthouses, and light commercial bathrooms
 Retrofit projects replacing single-lever or manual mixing valves
 Environments where temperature stability and scald protection are required
Key specifications
 Connection size: 1/2 inch
 Type: Thermostatic shower valve with temperature control cartridge
 Function: Maintains preset water temperature under variable inlet conditions
 Installation: Concealed or exposed depending on installation kit and piping
 Compatibility: Designed for use with standard domestic hot and cold supply pressures
How to use
Install the valve according to local plumbing codes, connecting hot and cold water supplies to the designated inlets and the shower outlet to the appropriate port. Set the desired temperature using the control interface; the thermostatic cartridge will regulate flow to maintain that temperature. After installation, check for leaks and verify that temperature remains stable when other fixtures are used simultaneously. Regularly test the temperature limit stop (if present) to ensure scald protection functions correctly.
Usage recommendations
For reliable operation, flush supply lines before installation to remove debris that could affect the thermostatic cartridge. Use water supplies within recommended pressure ranges and avoid exposing the valve to freezing conditions. Periodic servicing of the cartridge is advised in hard-water areas to prevent mineral buildup; follow GROHE service guidance for replacement intervals and maintenance.
