There are four types of kitchen faucet controls: Single Handle, Two Handle, Spray, and Wall Mount. You should always check the number of holes in your sink to determine the right kind. If you have a metal sink you can drill new holes, if necessary. Always carefully consider the spout height and reach. If you are going to cook, the spout needs to be long enough to go over the pan.
Single Handle Kitchen Faucets
Easy to conrol and change water temperature quickly. The design is generally good for single hole sinks, but not always (check the number of holes in your sink before purchase).
Two Handle Kitchen Faucets
Two handle kitchen faucets give you a more classic or vintage feel. You get more control of the water temperature since you have two handles. Your sink should have three holes (at least) to install this type of faucet).
Pull-Out or Integral Spray Faucets
The spout can be pulled out as a spray with integral faucets. Separate pull out sprays are available with most faucets. Once again, check your sink to see if their is hole for the separate spray nozzle. Integral spray faucets give you a lot of height and reach.
Wall Mount Faucets
Wall mount faucets allow you to choose unique basins. You can get an antique look with traditional basins or a very modern look with glass basins. You may even consider a hand blown glass spout with a glass basin.
