Thermostatic and manual describe how a shower mixes hot and cold water. Exposed and concealed describe where the valve is installed. These are separate choices: either control type can appear in different installation formats.
How the controls differ
With a manual mixer, you adjust the valve to find the temperature and flow you want. A thermostatic mixer regulates the blend towards a selected temperature within its operating conditions. It is designed to respond to changes in the incoming supplies rather than relying entirely on readjustment by the user.
Read safety features individually
A temperature stop, cold-supply failure response and a cool-touch body are different features. Do not assume that the word thermostatic confirms all of them. Check the model's documentation, commissioning requirements and maintenance instructions, particularly when planning a shared family bathroom.
Match the valve to the water system
Control preference comes after supply compatibility. Check pressure range, hot-water requirements, outlet configuration and the required installation depth. A qualified installer should confirm suitability and commission the valve according to its instructions. A thermostat cannot compensate for an incompatible installation.
Before you order
- Identify whether temperature control is manual or thermostatic.
- Verify each stated temperature and safety function.
- Check pressure, supply and outlet compatibility.
- Plan access for servicing and the specified maintenance.
Common questions
Does a temperature-stop button make every shower thermostatic?
No. A limiter restricts handle movement; thermostatic regulation is a separate mechanism. Use the technical description to identify the valve.
Are all thermostatic shower bodies cool to touch?
No. Surface-temperature protection is a separate design feature and should be expressly listed for the selected model.
