A spa having a one-piece, rotationally molded shell defining a reservoir for containing water including at least three sidewalls connected by an interior footwell, at least three exterior sidewalls, a coping interconnecting the reservoir sidewalls and the exterior sidewalls, and a floor beneath the reservoir footwell and interconnecting the exterior sidewalls. Water is circulated within the reservoir by a plumbing system which is disposed within an interior space defined between the reservoir sidewalls, the exterior sidewalls, the coping, and the floor; the plumbing system including a plurality of jets extending through the reservoir sidewalls; a plumbing harness; and a pump for circulating the water from the reservoir into the jets. It is also contemplated that a filter system and heating element may be provided and enclosed within the interior space of the spa. The one-piece, unitary spa shell construction provides several advantages over the prior spas including a portable, lightweight construction; a strong, durable polymeric frame and tub structure, which is substantially puncture proof, resistant to abrasions and scratches, and is chemically and ultra-violetly stable such that the tub may be used either indoors or outdoors and maintain a nice appearance despite exposure to the elements.
