Abstract
A system for supporting a spa shell may include a structural support paddle. The paddle may include a base portion and a paddle portion, connected to each other through an articulating joint such as a ball-and-socket. The top side of the paddle portion may include one or more pieces of cushioning material, such as EPF foam. The structural paddle assembly may be placed between the base of the spa and the spa shell. Typically 5 or more paddle assemblies are place in a spa for support, such as in the lowest areas of the spa shell and/or concavities, or convexities, of the spa shell. Compared to typical large blocks of foam used to support a spa shell from beneath, the structural support paddles provided increased room below the spa shell for ease of maintenance and installation, and more directly controlled support.
