The built-in products of the series Axor Citterio E impress through the intuitive handling they ensure in the shower. Due to their archetypal form, the various handle designs of the thermostat modules help to grasp their respective functions in no time at all: the cross handle signalises the regulation of the water volume, the cylindrical thermostat handle the temperature setting. A two-way-diverter indicates which shower is activated. Horizontally and vertically aligned, the modules present a harmonious overall impression.
