Abstract: A spa shell with integrated umbrella system includes a spa shell portion for containing a liquid and having a receptacle formed in a wall of the spa shell. An umbrella system is removably interfaced into the receptacle. The umbrella system includes a mast that is removably interfaced to the receptacle and an umbrella portion that is interfaced to the mast. The spa shell provides ballast to the mast and to the umbrella portion of the umbrella system.

Abstract: A spa with integrated folding table has a spa shell portion for containing water and a table that is hingedly connected to an upper inside surface of the spa shell. When the table is not being used, the table hinges down, the table lies against an inside surface of the spa shell (e.g. substantially beneath a surface of the water). When the table is in use, the table hinges outward from the upper inside surface of the spa shell in a horizontal plane. A support has a first end hingedly connected to a lower portion of the spa shell and a distal second end for connecting to an underside surface of the table. The support provides structural support to the table when the table is extended (hinges outwardly).

Abstract: A cushion for a hot tub or spa is molded in a rotational molding process. The cushion includes a decorative outer surface made from a plastic material (e.g., an outer wall and side walls, etc.). The cushion includes a a back surface for interfacing with a hot-tub shell or spa shell with at least one projection extending from the back surface towards the decorative surface. The at least one projection is for supporting the force of an object that is resting on the cushion. The cushion if formed in a rotational molding process.

Abstract: A method and apparatus for providing a substantially laminar flow of water in a swim spa is includes providing a basin holding a fluid. The method includes circulating water from the basin through at least one laminar flow swim spa jet, creating a substantially laminar flow of the fluid directed from one end of the swim spa. Each of the at least one laminar flow swim spa jet comprises a plurality of parallel, cylindrical tubes that reduce turbulence from the fluid as the fluid passes through the plurality of parallel, cylindrical tubes.
