Grohe Grohtherm 1000 Performance thermostatische douchekraan, 1/2

The Grohe Grohtherm 1000 Performance thermostatic shower valve delivers precise temperature control and lasting durability in a compact, wall-mounted design. Unlike basic mixer valves, it features GROHE TurboStat® technology that responds to pressure fluctuations in seconds, keeping your shower temperature stable without sudden bursts of hot or cold water. The GROHE SafeStop button at 38°C prevents accidental scalding, while the GROHE CoolTouch® housing stays cool to the touch even when hot water flows through. Finished in brilliant GROHE StarLight® chrome, this valve resists scratches and tarnishing for years of like-new shine.

Highlights

• Thermostatic cartridge maintains constant water temperature
• Safety stop at 38°C and CoolTouch® body for added protection
• StarLight® chrome finish is easy to clean and highly durable
• Built-in non-return valves and dirt filters ensure reliable operation
• Adjustable centre distance (135–165 mm) fits existing installations

In daily use

Set your desired temperature once and enjoy consistent warmth every time. The two-handle design separates temperature and flow control for intuitive adjustment. The valve works with standard 1/2" connections and suits most shower systems, making it a practical upgrade for both new builds and renovations. With a flow rate of approximately 20 litres per minute at 3 bar, it delivers a powerful yet efficient shower experience.
