A jet nozzle assembly is included which may be used in a jet apparatus having a jet housing and a jet head. The jet nozzle assembly includes a jet nozzle portion having a first end, a second end and a jet nozzle body extending from the first end to the second end of the jet nozzle portion, wherein the jet nozzle body is configured to provide an aerated flow of fluid for exiting the second end of the jet nozzle body and the jet nozzle body defines a passage therethough extending from the first end to the second end of the jet nozzle portion, and wherein the jet nozzle body has at least one opening for receiving fluid and/or air into the passage and has at least one fastening mechanism for attaching the nozzle body to a jet apparatus. The jet nozzle assembly also includes a jet nozzle cover having an exterior surface and an interior surface, and having at least one opening extending through the jet nozzle cover from the interior surface to the exterior surface for allowing passage of fluid, wherein the jet nozzle cover and the jet nozzle portion form a unitary structure.
