Hi Philipp,
the station is approx. 33.5 cm wide (left to right) and 31 cm deep (front to back). The width in the rear half (from 18 cm deep) can be reduced to 20 cm if you remove holders/trays for brushes/accessories etc on both sides. At the highest point it is 19.5 cm, i.e. at the back at the electrical connection point between the station and the appliance.
Best regards
Dan
