Abstract
A unit for use in a spa tub to provide a dry hydro-massage of the neck and shoulders. The unit 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 spa through a secondary port below the water line such that dry hydro-therapy is provided by the unit. The unit is mounted within the side wall of the tub spa and can be telescopingly adjusted between a position just below the water line and a position above the water line. With the unit in the upper position 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. Lower positions provide massage of lower body portions and facilitate storage and covering of the spa. The diaphragm unit is adapted to be utilized with various jet nozzles.
