A user controlling coin operating bidet assembly is comprised of a coin handling system with a coin collector box and an electrically operating bidet. The coin handling system contains optical coin validator, solenoid valves, coin flaps, optical coin counter, electronic timer, and microprocessor controlling those parts according to the signals triggered by the coins inserted. The electronic timer receives signal from the microprocessor and supplies power to another solenoid valve and a warm air blower connected to the bidet. A switch for selecting water and air is attached on the control panel of the bidet. 25 cents coin allows 30 seconds operation. Additional 25 cents inserted within 30 seconds extends the operation time for another 30 seconds. Emergency "HOLD" switch placed on the control panel holds the power to the bidet and stops the electric timer. Pressing "RESET" switch on the control board returns the bidet in a continuing mode.
