The essential kitchen disposal

Garbage disposals are a necessity for the busy cook. A disposal cuts up food waste into very small pieces that will flow easily through plumbing. There are two main types of disposals: batch feed, which requires a lid to be placed over the disposal to allow it to work, or continuous feed, which has a wall-mounted switch.

Residential disposals also come in a variety of horsepowers. Expect to pay $50 to $115 for a small disposal with a 1/3 horsepower motor. The price goes up with more horsepower that reduces the chance of jamming; a one-horsepower unit can cost between $150 and $380, depending upon brand and quality.

Though installation of a garbage disposal can be done by the handy homeowner, in most cases a professional contractor should be called in to handle the job. Installation generally costs between $80 and $150. If plumbing or electrical work is necessary, expect the price to reach $450 or more.
