The invention provides a method for supplying an aroma to a human bathing area. The method comprises sparging at least one air stream into the bathing area from a location beneath a water surface in the bathing area, and scenting the at least one air stream prior to the sparging step by contacting the air making up the at least one air stream with an aromatic aroma source. The aromatic aroma source can be in the form of a scent delivery module is positioned in the air flow path to supply bubbles to the pool or tub. One embodiment of the module comprises sidewall means defining an inlet, an outlet, and a gas flow path for a gas stream extending between the inlet and the outlet. The gas flow path is divided along a portion of its length into a first flow path and a second flow path. A first portion of the gas stream flows through the first flow path and a second portion of the gas stream flows through the second flow path. The first gas flow path and the second gas flow path are rejoined for a combined flow path through the outlet. The sidewall means further comprises a vaporizer chamber positioned in the second flow path for introducing scent vapors into the second portion of the gas stream.
