In 2020 we asked 750 people, including Grohe owners, all about their hot water taps.
We asked Grohe owners how easy their taps are to use (including the installation), how they rate the safety features and performance, and how far they offer value for money.
In our survey, we asked people how satisfied they are with their Grohe hot water tap and whether they would recommend it to a friend. We combined these to create an overall customer score.
