The Nabis DO1193 Thermostatic Cartridge (Part Number DO1193GH) is a replacement thermostatic cartridge designed for compatible Nabis shower valves that utilise this specific thermostatic module. It restores precise temperature control and balanced hot/cold mixing where the original cartridge has worn or failed.
This thermostatic cartridge sits inside the shower valve body to control and blend hot and cold water to a set temperature. Replacement is typically required when the shower valve no longer holds a stable temperature, fluctuates between hot and cold, or the internal mechanism becomes stiff or unresponsive due to wear.
Isolate the water supply before servicing the shower valve. Remove the handle and trim to access the internal cartridge chamber, extract the old cartridge, and insert the DO1193GH unit ensuring correct orientation and sealing. Reassemble the valve trim and test temperature control for smooth and balanced operation.
