PURPOSE: To avoid such inconvenience as bathing with a discharge water having an improper temperature.

CONSTITUTION: If it is judged that the actual discharge water temp. T of hot water flowing into a shower head lies out of the proper temp. range, a discharge water nozzle 27 is rotated until it faces a discharge window 73, and switching is made from all nozzles but the nozzle 27 showering. This changes the direction of the discharged water from the object to be showered (user) ahead of the shower head A (as shown by arrow a4) into the direction wherein no discharge water is poured on the object (as shown by arrow a5).
