A reservoir dispenser for a bidet apparatus includes a housing unit having a first chamber and a second chamber, wherein the first chamber can hold liquid wash solution separate from the second chamber. The first chamber can include a lid with an opening therein; an activator located within the opening of the lids; and a stem and end piece located within the first chamber. The second chamber can include a water inlet and a water outlet for flow of water through the apparatus. Located between the first and second chamber is a check valve, which allows for the controlled transfer of liquid wash solution from the first chamber to the second chamber.
