An improved bearing and shaft assembly includes a bearing assembly having an outer bearing member and an inner bearing member, and a shaft assembly having a shaft member, a shaft protection member, and a locking mechanism. The outer bearing member has a cavity for receiving the inner bearing member, and fits within a cavity of an impeller. The shaft assembly is secured within a housing of a jet assembly. The shaft protection member has a cavity for receiving the shaft member. The shaft protection member fits within the cavity of the inner bearing member. Also, a jet assembly, which includes the improved bearing and shaft assembly, may be coupled to a motor assembly. The jet assembly further includes the housing that includes at least one inlet aperture and at least one outlet aperture, and an impeller positioned within a cavity of the housing.

An improved swim spa is described which has a tank having a head end and a foot end filled with water. A forward current is created by pumping equipment which directs the forward current from a head end of the tank, past a swimmer in the water to a foot end of the tank. The pumping equipment may be attached to a removable wall insert to which may be removed to allow easy repair and maintenance. The forward current allows the swimmer to swim in place. The width of the forward current is chosen to be at least twice its depth. A diverter at the foot end of the tank has a curved surface for redirecting the forward current toward the sidewalls and then back toward the head wall in a horizontal plane and downward and back toward the head wall in a vertical plane.

A therapeutic light emitting diode lighting system to treat seasonal affective disorder, to be provided at an upper portion of a hot tub basin above an indicated maximum water level, the hot tub basin defining at least one seat portion and corresponding headrest defined by the hot tub basin such that a facial region corresponds to the headrest, the facial region corresponding to a facial area of a person seated in the seat portion and supported by the headrest, the therapeutic light emitting diode lighting system including at least one array of light emitting diode (LED) bulbs provided on the upper area, the LED bulbs configured to illuminate colors and wavelengths selected to treat seasonal affective disorder, the LED bulbs being angled to direct light at the facial region of the hot tub body.

Disclosed is a circumferentially revolving water outflowing device, having a main body, an upper cover, a lower cover, a water outflowing assembly and a revolving swing. The upper and lower covers are respectively covered on an upper and a lower end face of the main body, forming a water inlet cavity therein. The water inlet cavity is provided therein with an impeller, a speed reduction duplex gear and an output gear. The output gear is provided at an axial center portion thereof with a first rotating shaft, which rotates synchronously therewith, extends through the water inlet cavity out of the lower cover and is fixedly connected to one end of the revolving swing. The other end of the revolving swing is rotationally connected to an upper end face of the water outflowing seat. The revolving swing drives the water outflowing assembly to rotate under the driving of the output gear.
