PROBLEM TO BE SOLVED: To provide a bathroom heater/dryer which enables a user to take a comfortable mist bath by shortening the amount of time for switching a water temperature.SOLUTION: A bathroom heater/dryer is configured to supply fine droplets to the inside of a bathroom by a fine droplet generating means and an air blowing means and to close a flow control valve before a fixed time of stopping the air blowing means. Since the flow control valve is completely closed before the fixed time of artificially or automatically stopping the air blowing means, the bathroom heater/dryer which enables a user to take a comfortable mist bath is obtained by shortening the amount of time for switching a water temperature.
