A washing device [ 1000 ] is described which is uniquely adapted for use by elderly, handicapped, or other users which use one hand for support and have only one hand free to operate the device. The supply line [ 1010 ] directs the fluid to a fluid valve [ 1210 ] which is controlled by a first clicking mechanism 1231 which toggles the valve between an “open” position directing fluid flow to an additive valve [ 1240 ], and a “closed” position which stops fluid flow. Additive valve [ 1240 ] is also toggled between two positions by a second clicking mechanism [ 1232 ]. In its ‘fluid only’ position, only fluid is allowed to pass out of the additive valve [ 1240 ] through a mixing chamber [ 1400 ] and out of a changeable head [ 1700 ] to the user. In another embodiment, a single three-position valve performs the same functions.
