An improved therapeutic spa, hot tub, or hydrotherapy system includes one or more jet assemblies to form streams of water which translate in at least two degrees of freedom over a substantial portion of the user's body. The jet assemblies preferably move in patterns under automatic computer control as well as manual feedback by the user. The system preferably includes a body support, such as in the form of a chair. The support is at least partially water permeable so that the streams of water impinge the user through the body support. The jet assemblies preferably include unitary nozzles, pumps, and motors.
