A douche apparatus for vaginal application with a high temperature thermostatic valve located close to the source of mixed hot and cold water immediately after an adapter for connecting the apparatus to the water faucet. The apparatus has a hollow handle with a threaded extension which receives a disposable nozzle for vaginal introduction of douche liquids received through the handle. A flexible hose connects the thermostat output to a backflow prevention valve at the handle input to prevent douche additives introduced through a mixing chamber in the handle from being introduced to the water supply. A gate valve in the handle controls liquid volume and pressure in the flow channel exiting the handle through a macro screen for particulate matter filtration and a micro screen for bacterial filtration of the douche liquid immediately prior to exiting the handle and communication to the nozzle for vaginal cavity entry. The nozzle has downwardly curving channels extending from its hollow interior to its surface orifices to provide indirect douche liquid contact with vaginal surfaces. The handle end of the nozzle has a conically flared collar sloping outward and away from the nozzle to deflect douche liquid emerging from vaginal cavity from the handle and the user.
