Functionality and user-friendliness were placed centre stage in the design of the F2 shower toilet. The integrated heating technology ensures a pleasant water temperature. It heats cold water to up to 35 degrees Celsius within a few seconds. The arched arrangement of the spray nozzles achieves a wider spray range: This prevents dirty water from flowing back to the surface of the nozzles and accumulating there. The flushing mechanism was deliberately designed to operate without batteries. The toilet flush is mechanical and therefore works reliably even in the event of a power failure.
