PROBLEM TO BE SOLVED: To provide a bathroom heating drier capable of preventing hot air from blowing out from a main body of the heating drier even if cooling air operation is carried out under a state in which a heating heat exchanger is heated.SOLUTION: This invention relates to a bathroom heating drier comprising a main body 2 of a heating drier, a heat source machine 36 for generating hot water and control means 128 for controlling the operation of the main body 2 of the heating drier and the heat source machine 36. The main body 2 of the heating drier comprises a circulation fan 10 for circulating air through a circulation flow passage, a heating heat exchanger for heating air under utilization of hot water from the heat source machine 36, and a ventilation fan 34 for ventilating air through a ventilating flow passage. In the case of a cooling air operation mode, the control means 128 operates the circulation fan 10 and the ventilation fan 34 if the detected temperature of hot water going temperature detecting means 84 is equal to or less than a first set going temperature to perform cooling air operation and when the detected temperature exceeds the first set going temperature, it operates the ventilation fan 34 of the main body 2 of the heating drier to perform first cooling air preparation operation.
