side showers allows the user to enjoy
water from all sides. Comfortable - the GROHE Aquadimmer is an
operating lever that allows choosing between the overhead and hand
shower and controls the flow rate at the same time.
Safe – for people with children, we recommend the use of a
thermostat fitting, which ensures a constant water temperature to
provide protection against scalding.
To ensure flawless function of the side showers, a 3/4” stop valve
is recommended as a minimum.

that the maximum amount of water produced can run off safely.
