A tub spout assembly is configured to be supported within the overflow opening in the sidewall of a bathtub. The tub spout assembly illustratively includes an overflow body defining an overflow passageway, and an inlet tube supported by the overflow body and defining an inlet passageway. A spout is fluidly coupled to the inlet tube and defines a spout outlet to dispense water from the inlet tube into the bathtub. A spout cover illustratively receives the spout and includes an inner wall defining at least one opening. The at least one opening is illustratively in fluid communication with the overflow passageway and the inlet passageway. Illustratively, a diverter assembly is supported by the spout and is configured to selectively open and close fluid communication between the inlet passageway to the spout outlet.
