A composite water closet and bidet comprising a water closet adapted to receive a bidet and a bidet adapted to be received by said water closet; said adapted water closet including a bowl defining a water basin and a siphon passageway in fluid communication with said water basin, said water closet having an upper peripheral rim surrounding said basin including a rear edge portion; and an adapted toilet seat overlying said upper rim of said water basin and being pivotally connected to said water basin adjacent said rear edge portion of said rim; said adapted bidet comprising a bidet basin having a bidet seat portion and a bidet basin portion, said bidet seat portion normally overlying said toilet seat and being pivotally connected to said water basin adjacent said rear edge portion of said rim said bidet basin portion having an upper edge and being integrally connected along said upper edge to the inner peripheral edge of said bidet seat portion and extending through the opening of said adapted toilet seat and being received by said adapted water basin; said toilet seat and said bidet seat portion having similar configurations in plan and having an approximate figure configuration of their openings. 9. A composite water closet and bidet as defined in claim 8 wherein said siphon passageway having an inner wall over which water flows from said water basin, said siphon passageway also having an inverted U-shaped portion formed over said wall to lift the liquid contennt of said water basin over said wall during siphon action, the highest elevation of said inverted U-shaped portion being at a predetermined distance below said bidet basin to prevent the water level in said water basin from touching the underside of said bidet basin portion when the water level rises to its highest elevation prior to commencement of siphon action. 10. A composite water closet and bidet as defined in claim 8 wherein said toilet seat and said bidet seat portion have straight rear edges; said rear edge portion of the water closet having a stepped configuration adjacent said straight rear edges, the lower step being on the same plane with said toilet seat and underlying said straight rear edge of said bidet seat portion, the upper step being on the ame plane with said bidet seat portion; said upper and lower steps also being sloped towards said water basin. 11. A composite water closet and bidet as defined in claim 8 wherein said bidet basin portion includes an upper rear edge portion, adjacent said bidet seat portion, having an overflow drain opening therein, said bidet basin portion also including a lower basin portion at the lowest elevation of said basin portion, having a drain opening therein. 12. A composite water closet and bidet as defined in claim 11 wherein said bidet basin includes a shield exteriorly of said overflow drain opening to direct overflow water directly downward into the water basin along the exterior side of the rearward portion of said bidet basin portion, said shield providing an aperture, adjacent said bidet seat portion, allowing water to drain directly downward into said water basin along the underside of the rearward portion of said bidet seat portion when said bidet basin is in the vertical pivotal position. 13.
