A hydrotherapy jet unit used singly or in multiples for jetting pressurized water and air under submerged conditions into a water-bearing vessel, and provided with a means to fix the direction of jetted flow at an optimum angle not susceptible to change of alteration by the vessel user; however, each unit being readily adaptable to provide directional jetted flows at differing fixed angles by means of removable and interchangeable deflection nozzles. The unit features both water and air supply pipes entering the hydrotherapy jet housing at its rear extremity, said pipes being substantially parallel to each other and axially aligned with the jet action produced within the unit. This arrangement provides a means for simple removal and replacement of the unit if required without need to damage, alter or reconfigure pipe means supplying either water or air. An additional feature is an integral and functional cover cap for the frontal or exit end of the unit which is easily removable and interchangeable, and which affords a means for aesthetic change of unit external appearance whenever differing colors or finishes are desired by the user.
