PROBLEM TO BE SOLVED: To provide a toilet device capable of obtaining a specified warm water control in a low cost constitution without use of a flow rate sensor. SOLUTION: A detection signal from a seating detection means 16 is input, a changeover switch 9 is changed over to a nozzle washing passage and opens a cutoff solenoid valve 4 and detects inflow water temperature on the basis of the detection temperature of a temperature detection means 17 after a specified time interval and an electric power lower than 1/2 of the rated input is input in a heater 8, water existence is detected on the basis of the change of the detected temperature of the temperature detection means 17 and the flow rate is detected based on the time up to the change of the detected temperature of the temperature detection means 17, and the input power to the heater 8 is changed stepwise and the flow rate is detected from the time lag of the temperature change between a plurality of temperature detection means.
