Abstract
A portable spa apparatus comprising a peripheral side wall composite and a floor, which combine to define a tub capable of accommodating at least one occupant and a quantity of liquid. The peripheral side wall composite has an inner liquid-impervious layer; a central layer of flexible, foamed thermoplastic material providing insulating capabilities; and an outer layer of reinforced material. The outer layer has properties that render it capable of withstanding stresses resulting when the spa is partially filled with liquid. Moreover, the peripheral side wall, when constructed, is capable of standing generally upright when the tub is partially filled with liquid. The peripheral side wall and floor are of such construction to be portable and collapsible. Methods for making and using a portable spa apparatus are also disclosed.
