Abstract: A portable bidet which comprises an adaptor to facilitate the interconnection of the bidet with a source of water under pressure; a water discharge tube and nozzle mounted for movement from an inoperative position substantially beneath the internal rim of a toilet bowl to a predetermined operative position wherein the nozzle lies substantially centrally of the bowl; a valve for variably controlling the flow of water to the discharge tube and nozzle, and; a manually operable lever pivotally mounted adjacent the bowl but externally thereof, whereby initial movement of the lever affects movement of the discharge tube and nozzle to the operative position, and continued movement of the lever in the same direction affects gradual opening of the valve means without causing further displacement of the discharge tube and nozzle from the operating position. In the preferred embodiments this adaptor provides for the reception of hot and cold water streams, and the mixing thereof to a predetermined operating temperature.
