Abstract: 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.

Abstract: 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. This allows the swimmer to swim in place. The width of the forward current is chosen to be at least twice its depth. A diverter is positioned at the foot end of the tank. The diverter 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. In various embodiments, the diverter may only employ curved surfaces to turn the forward current to the sidewalls and then back to the head end. It also may only have curved surfaces to divert the forward current downward, then toward the head end.

Abstract: A hydrotherapy spa includes an upwardly open, U-shaped, cross-sectional, waterproof spa shell defining a receptacle for holding water. The spa shell includes a horizontal seat portion and an integral seat back extending generally vertically upwardly therefrom. A water supply manifold is sealably mounted to the exterior of the spa shell, is spaced therefrom and forms a manifold chamber, with the supply manifold overlying a portion of the seat and the seat back. A plurality of small diameter apertures are formed in the spa shell opening to the manifold chamber. Water under pressure is circulated from the interior of the spa shell to an inlet port opening to the manifold chamber. The water is discharged through the small diameter apertures into the interior of the spa shell and against the back and buttocks of an occupant within the seat area seated at a hydrotherapy seat defined by the supply manifold and the seat and seat back of the spa shell which include the small diameter apertures.
