A sheet product roll holder may include a support arm, a spindle, a flowable material container, and an automated flowable material dispensing mechanism. The support arm may define a first longitudinal axis. The spindle may be coupled to the support arm and define a second longitudinal axis extending transverse to the first longitudinal axis, and the spindle may be configured to rotatably support a roll of sheet product thereon. The flowable material container may be positioned at least partially within the spindle and define a third longitudinal axis extending coaxially with the second longitudinal axis, and the flowable material container may include a container body and a volume of a flowable material positioned within the container body. The automated flowable material dispensing mechanism may be positioned at least partially within the support arm and configured to dispense the flowable material from the flowable material container.
