The original toilet facilities beneath Alexanderplatz date from the 1920s. Before operation was taken over by Wall AG, it had been converted several times. Thanks to a new flour plan, an elegant design, special lighting and the comfort of the installations, a bright, modern service facility was created. The design for the sanitary section is characterised by glass surfaces, white mosaic tiles, anthrocite-coloured stairs and a stone flour. From a central reception counter, the toilet areas with a total of 18 toilets and a nappy-changing area spread out in star formation.
Compact sewage disposal units with integrated swing check valve, single or twin pump station.
