One or more curved cavities are disposed below one or more of the air jet holes to create a turbulent air flow in the area of the curved cavity whereby to expel any residual water accumulated in the curved cavity after the water level in the bathtub enclosure has been lowered below the air jet holes with the conduit pressurized by air from the blower to purge the conduit. A water evacuating conduit may also be connected in such cavities for the evacuation of residual water therefrom.
