Typical ranges for a basic garbage disposal installation can be anywhere from $150 to $500, though more complex installations or upgrades may cost more. The main factors that influence the cost include the type and size of the disposal unit, the complexity of the installation (e.g. if electrical or plumbing work is required), and the labor rates in your local area.
