Abstract
A portable spa in which a confining outer wall rests on the ground or other flat surface. A water impervious liner is suspended from the top of the wall and forms a barrier for holding water. The liner is formed with a double-wall construction with an inner sheet attached around the margins to the outer sheet to form a confined space. A pump for recirculating water through the pool has its outlet connected through a conduit to the confined space so that water is forced into the confined space under pressure. A portion of the inner sheet is shaped to form a raised seat on the bottom of the pool when inflated, while another portion of the inner sheet extends above the seat to form a back rest when inflated. The pump directs water through a series of jets through the sides of the pool to provide a massaging action.
