The 38 °C stop is a detent, not a safety device · review
A solid brass thermostat that arrives with its rosettes, its S-connections and its fixings, from a German maker who answers the phone.
The bottom line The complete box from a maker you can telephone. Its 38 °C claim needs restating, and the two figures a thermostat is judged on are absent.
A chrome thermostatic shower mixer in solid brass, with a 38 °C detent, separate flow and temperature controls, a ½ in hose connection, two rosettes, two S-connections and the complete fixing set.
The maker calls the 38 °C stop scald protection. It is a detent: a mechanical stop the hand feels, released by pressing a button. It prevents an absent-minded turn to 50 °C. It does not guarantee the water leaving the mixer is safe, and where genuine scald prevention is required a thermostatic mixing valve specified for the job is what provides it.
This site reports what the maker writes and says what the part is.
Rosettes, S-connections, fixings, German instructions. A mixer bought without them is a mixer that waits a week.
Centre distance and minimum operating pressure. The first can be worked around by the S-connections; the second is what decides whether a thermostat holds temperature on your system.

No. It is a mechanical detent, released by a button, that stops the handle being turned absent-mindedly into hot water. Genuine scald prevention is the job of a thermostatic mixing valve specified for the purpose. This page reports the maker's wording and does not repeat it.
They are the curved fittings between the wall outlets and the mixer, and because they rotate they absorb a small mismatch in your wall centres. Supplying them means the fitting is a job rather than a second order.
Shower thermostat · TurboStat cartridge · 38 °C detent · EcoJoy flow limiting with a release button · S-connections and metal rosettes
A thermostat built around a flow-limiting button you press to release full flow — and a water-saving claim published as a percentage with nothing behind it.
Best for: A household that wants a lower default flow without having to think about it, on a known standard wall installation.
≈ £105 / 96 €
Shower thermostat · 150 mm ±12 centres · G1/2 DN15 · SafetyStop 40 °C · EcoStop 10 l/min first position · silencer fitted
A thermostat that publishes its centre distance with a tolerance, its limited flow in litres per minute, and a built-in silencer — three things nothing else on this page states.
Best for: An existing wall installation whose centres are close to but not exactly 150 mm, in a bathroom where shower noise carries.
≈ £138 / 111 €
Shower thermostat · 150 mm centres stated · 38 °C detent, lockable · plastic handle stated · takes any standard hose
A surface-mounted thermostat with a lockable 38 °C button and a plastic handle the maker defends on purpose — because limescale seizes metal ones.
Best for: A household where the temperature setting should stay put — the same shower, the same setting, every day.
≈ £40 / 50 €
