Grohtherm 1000 New — shower thermostat: always the right temperature.
Thanks to the GROHE TurboStat® technology, this shower thermostat will deliver the desired water temperature reliably within a fraction of a second. To protect you and your family from scalding, it comes with a preset temperature limit of 38°C. If desired, higher temperatures can be selected upon deactivating the SafeStop button. In this mode, the SafeStop Plus feature ensures that the temperature will never exceed 50°C, and the thermostat will always be safe to touch thanks to the GROHE CoolTouch® technology. To contribute to environmental conservation, the integrated EcoButton allows you to reduce your water consumption by up to 50% while showering. Crafted with ergonomically shaped metal handles and finished in glossy GROHE StarLight® chrome, this exposed shower thermostat will be a stunning eye-catcher in your bathroom.
Constant water temperature thanks to reliable GROHE TurboStat® technology:
Our precise control technology ensures an instant water flow at the desired temperature and keeps it constant irrespective of any fluctuations in water pressure or supply.
Easy to clean thanks to the GROHE StarLight® chrome coating:
Just wipe the tap down with a dry cloth - the ultra smooth surface finish is scratch resistant and ensures a lasting luminous sheen. You'll save plenty of time cleaning while your tap always looks shiny and new.
GROHE CoolTouch® – never too hot to handle:
Thanks to the GROHE CoolTouch® technology, the temperature of the tap body will never exceed your shower temperature. Engineered with an integrated cooling channel separating the hot water supply from the outer surface of your thermostat, it is always safe for you to handle. This feature is especially important to protect children from scalding on hot tap surfaces, making your bathroom safely enjoyable for the whole family.
GROHE EasyLogic – clear markings on the tap body for easy handling:
The temperature markings are on the tap body rather than the knobs, so you can immediately see which way to turn for your desired temperature. Knobs and button are designed for easy and intuitive handling by the whole family.
GROHE MetalGrip – high-grade metal handles for excellent usability and high durability:
With their ergonomic metal handles, these GROHE fittings offer optimal grip. Crafted in fluid shapes and made from a high-grade material, they can be operated with minimal effort, even with soapy hands, and come with the high durability characteristic of all GROHE products.
EcoButton – reduce your water consumption by up to 50% at the push of a button:
Using this button you can select either a full water flow, e.g. for quick tub filling, or reduce your water consumption by up to 50% – without compromising on your comfort!
SafeStop Plus – extra safety and scalding protection:
Your safety is always a top priority for us at GROHE. Our SafeStop Plus system comes with a preset water temperature limit of 38°C. If desired, higher temperatures can be selected upon deactivating the SafeStop button. For extra safety in this mode, SafeStop Plus ensures that your water temperature does not exceed 50°C.
GROHE EcoJoy® with water-saving function for reduced consumption:
GROHE EcoJoy® reduces water consumption by up to 50% without compromising on performance. Whenever you turn on your tap, you will enjoy a full jet of water while saving money nonetheless.
