To provide a bathroom heating drier capable of using a heating system or a drying system properly according to application.

The bathroom heating drier 1 is provided at its internal part with a heat exchanger 12 to heat air through circulation of hot water; and a supply fan 10 to discharge air, heated by the heat exchanger 12, through a hot air outlet 21. Further, an electric heater 19, such as a far infrared radiation heater, is exposed to the under surface of the bathroom heating drier 1. For example, during preheating before bathing, by operating the supply fan 10, hot air heated by the heat exchanger 12 is supplied (an electric heater 19 is turned off) and temperature in the bathroom is increased. During bathing, a supply amount of hot air is reduced and temperature in the bath room is kept at a constant value, and by turning ON the electric heater 19, a person taking bath is irradiated with its radiation heat.
