6 Features Included In This Product Explained

Grohe TurboStat

Grohe TurboStat

It is a revolutionary thermostat shower technology which is the fastest and most accurate on the market today. The increased sensitivity of the thermoelement now enables these thermostats to react to water pressure changes at much quicker speeds and provide water at the desired temperature in a fraction of a second while maintaining it for the entire shower.

Grohe SafeStop & SafeStop (Plus)

Grohe SafeStop & SafeStop (Plus)

It is an excellent safety feature for homes with children, preventing scalding accidents. This button is factory set at 38°C, which prevents users from increasing the water temperature beyond a specific limit. When required, higher temperatures can be selected by pushing the button. Additional safety is provided by the SafeStop Plus limiter, which ensures that the temperature does not exceed 43°C.

Grohe DreamSpray

Grohe DreamSpray

This feature allows you a showering experience unlike any other. It offers an even water distribution to every nozzle, while the SmartRain spray created by the Spray Dimmer on the hand shower reduces water use by up to 40%. The aesthetic factor is enhanced by the three styles of head shower design.

Grohe EcoJoy

Grohe EcoJoy

According to Grohe, the EcoJoy technology enables reduced water usage by your tap by up to 50%. It is done without compromising on the water spray, which allows a full jet of water from the tap and provides excellent value and comfort in a single unit.

Grohe StarLight

Grohe StarLight

It is a durable, long-lasting surface that ranges from matte to shiny, like a diamond. This finish or long-lasting surface quality of every product from this manufacturer keeps it looking as good as new for years to come. The pledge of continuous improvement has refined this unique plating process to bring you a surface polish that is robust and immaculate and finds no match anywhere across the globe. A key contributing factor is rigorous quality control measures and regular healthy investments.

Mick Asked :

Does the 800 come ready to straight swap with the existing old Grohtherm 1000?

Answered By QS Team Answered by the QS Technical Team

If the existing water inlet pipes are 150 mm apart, the Grohtherm 800 will fit as a direct swap indeed. You may not even need to use the supplied 'S' unions.

lynda Asked :

What is the difference between the 800 and 1000 Grohe Grohtherm mixer valve?

Answered By QS Team Answered by the QS Technical Team

The main difference is aesthetic, the body is a different shape, and the handles are different. Also, 1000 has the Cooltouch feature; when the body of the valve stays cool, the 800 doesn't have this feature.
