  • Modular system for spas and bathing systems
    Patent number: 6256805
    Abstract: An upgradable spa or bathing system where jets are mounted on jet panel that covers a pod. The jet panel and pod enclose the air and water supply systems to the jets, which are configured with a manifold system to easily release the jets and the jet panel for repair or replacement of the jets. A separate upper panel covers the upper portion of the pod and includes an attachment to the spa shell and a headrest. The jet panel is held in place by engagement with structure on the shell and the upper panel and may be replaced without also replacing the head rest or the shell attachment of the top cover.
