Higher horsepower units (3/4 HP and up) handle tougher food waste and jam less often, but cost $50–$150 more than basic 1/3 HP models.
If an outlet or hardwired connection already exists under the sink, installation is quick. Running new electrical adds $100–$200.
Most disposals fit standard 3.5-inch drain openings, but non-standard sinks may need an adapter or drain rework.
If your dishwasher drains through the disposal (common setup), the installer must connect the dishwasher drain hose and knock out the plug.
Premium disposals with sound insulation and anti-vibration mounts cost more but significantly reduce kitchen noise during operation.
