ABSTRACT:
A construction which permits existing swimming pools to be provided with a spa at low cost includes a removable partition which is mounted in the pool to define the space to be used as a spa. A special gasket forms a seal between the partition and the pool. Valves are installed in the existing pool suction pipe and pool return pipe to permit the flow to be diverted to the spa. No excavation is required to install the spa. An adjustable template is used to determine the proper size and shape of the removable partition. The pipe through which water enters the spa is provided at its end with a jet nozzle which includes a venturi for introducting air into the incoming stream of water.
