What is a thermostatic shower?
A thermostatic shower is a type of mixer shower featuring an internal thermostatic valve that blends hot and cold water to maintain a constant, precise temperature. Fed directly from your home’s hot and cold supply, it ensures a stable flow that remains consistent, even when other taps in the property are in use.
What Is a Concealed Shower Valve?
A concealed shower valve is an ultra-discreet option ideal for minimalist interiors. The functional elements of the valve are fitted behind the wall, leaving only a sleek control plate and levers visible, allowing you to regulate the flow and temperature of your thermostatic shower with refined simplicity.
How Do I Maintain a Concealed Thermostatic Shower Valve?
If your thermostatic shower begins to underperform - perhaps delivering reduced pressure or inconsistent temperature - your valve may simply require routine maintenance. Limescale and debris can accumulate inside the valve body, restricting water flow. The guide below outlines how to clean and care for your concealed shower valve to ensure optimal performance.
Maintenance Guide
Before Beginning
- Turn off and isolate all water supplies to the shower.
- If you’re unsure how to isolate your system, consult a qualified plumber.

Wipe thoroughly with a damp cloth to remove any remaining residue. -
Clean the Thermostatic Cartridge
Prepare a mild solution of water and vinegar.
Immerse the cartridge for approximately 10 minutes.
Brush gently to remove any limescale, then rinse under fresh water. -
Reassemble the Valve
Refit all valve components in reverse order, ensuring every O-ring is intact and properly positioned.
Tighten all parts carefully using your adjustable spanner.
Refit the thermostatic cartridge with the pipe facing outward and secure firmly. -
Replace External Components
Reattach housings and check O-rings once again.
