A unit for use in a tub or spa to provide a dry hydro-massage of the neck and shoulders. The unit mounts to the tub edge and includes a diaphragm which sealingly covers a discharge jet such that the fluid will flex the diaphragm into massaging relationship with the user's body. The water is exhausted into the tub through a secondary port below the water line such that dry hydro-therapy is provided by the unit. The unit is mounted to the side wall of the tub spa. The inflation of the diaphragm is controlled by pressure regulating ports formed within the housing to control the exhaust of fluid from the jet chamber. In one embodiment, the ports are variable to vary the inflation pressure of the diaphragm. With the unit mounted to the tub the user may remain seated within the spa while the unit provides a dry hydro-massage of the neck and upper back normally positioned above the water line. The diaphragm unit is adapted to be utilized with various jet nozzles.
