Installing a dishwasher costs $130-$300 in labor when you are swapping a new unit into an existing hookup, the most common job. A first-time install where no dishwasher existed runs $300-$1,300 in labor because it adds a cabinet cutout, a water-line tap, a drain connection, and power. Big-box retailers like Lowe's and Home Depot often install for $130-$200 (sometimes free with the appliance), while independent plumbers charge $200-$500. Add $25-$150 to haul away the old machine.
