Abstract: A modular spa comprises a spa shell that includes at least one support member integrally molded therewith, and a support frame supporting the spa shell at the support members. The support frame consists of a number of elongate polymeric support struts that are secured to the support members. The spa shell is typically molded from a composite acrylic/ABS sheet, and has a substantially upright side wall and a rim extending outwardly from the side wall. The rim is integrally molded with and substantially surrounds the support member. The support member is typically a metal or polymeric extrusion, and includes a substantially vertical surface and a flange extending outwardly from the vertical surface. The rim includes a substantially vertical rim face having a lip that surrounds the flange. The spa is enclosed by a cabinet that is secured to the outer surface of the spa shell, below the lip.
