Düsseldorf, May 2021 – A thermostat is a must-have for every well-planned bathroom. A recently conducted survey on showering behavior across several countries with the German
research institute explorare showed that 37% of respondents have pointed out one particularly annoying factor when showering: temperature fluctuations. (2) With the new GROHTHERM 500 as the intelligent heart of the shower, complaints like these are a thing of the past. GROHE’s latest product solution impresses with steady comfort temperatures, personal settings andoptimal convenience – at an affordable price. Carsten Geers, Brand Manager GROHTHERM & Rapido, LIXIL EMENA, explains what installers and planners can expect from the latest addition to the GROHE thermostats portfolio and presents convincing arguments for consultations with customers:

“Why should I recommend a thermostat to my customers?

Thermostats are not a new invention – professionals have been working with them for a long time, have witnessed the evolution of this intelligent showering technology and know how it
works. We found out that over 35% of consumers (3) would like to replace their lever mixer with a thermostat - clearly there are customers who can be convinced to upgrade their shower when installers and planners offer the right arguments at the right time.

From my point of view, there are three key arguments:

1. Thermostats are safe mixers, especially for children and seniors. In contrast to a lever shower mixer, our thermostats are equipped with a 38 °C SafeStop Button. As the name
indicates, it limits the water temperature to a comfortable 38 °C and prevents scalding from burning hot water. Additionally, our thermostats come with an optional 43 °C SafeStop Plus temperature limiter. It can easily be activated during the installation and limits the temperature to 43 °C, thereby preventing children or visually impaired persons from turning
up the temperature unintentionally and scalding themselves. This is a big plus for multifamily homes and hotels or really any bathroom project.

2. Now that the bathroom is increasingly turning into an oasis of well-being, consumers are increasingly looking for solutions that enhance comfort. Our thermostat technology is the
answer here. Even with multiple water sources running simultaneously, the thermostat allows users to be in control of the temperature as it balances temperature peaks and
prevents cold or hot surprises during showers. From my point of view, this is one of the major benefits - especially considering that temperature fluctuation is one of the main pain
points for end consumers. (4)

3. What many consumers do not know: A shower equipped with a thermostat saves water in several ways. GROHTHERM thermostats all come with the EcoButton – an easy-to-use
and effective feature: It reduces the water flow, saving up to 50% water without a noticeable difference for users. Additionally, the thermostat cartridge makes it easy to find the desired
temperature: Even if a user likes to turn the water off and on while showering there is no need to find the right lever position again. In the end, this not only saves valuable resources
but also leaves more money in customers’ pockets - a quite considerable sum over the product’s life cycle.

Why should I choose a GROHE thermostat?

Our product portfolio must be as diverse as our customers’ projects are individual. For us, the key in product development is to provide installers and planners with the right solutions.
Our portfolio is set up to meet different requirements regarding functionalities but also budgets:

Take, for example, the recently introduced GROHTHERM 800 Cosmopolitan. Besides the TurboStat cartridge, this product stands out due to the solid metal handles which function not
only as a design statement: Their greatest benefit is the so-called Ergorim on the back which ensures a firm grip even when hands are wet or soapy. This makes GROHTHERM 800
Cosmopolitan a perfect upgrade for any shower, and there is also a variant for the bathtub.

Our portfolio also includes the even more sophisticated new GROHTHERM 1000 Performance with two additional key features. Because we have integrated our 100% GROHE
CoolTouch technology, the thermostat’s body never exceeds the shower temperature – a good argument especially if children or seniors live in the same house. Since water conservation is also playing an increasingly important role for customers in bathroom planning, the 1000 series additionally features an AquaDimmer with an EcoButton for controlling the hand shower
in the bathtub.

Our newest addition to the thermostat family is GROHTHERM 500 – I would describe it as the perfect entry into the GROHE thermostat world. From a price point of view, it is equal to a
single-lever mixer but offers customers more benefits.

What are the benefits of GROHTHERM 500?

GROHTHERM 500 is the optimal entry-level product that enables users to try out the benefits of a thermostat - the EcoButton, the SafeStop and the SafeStop Plus feature. It comes with
the well-known GROHE quality while also fitting tighter budgets – the perfect alternative for single-lever mixers.
