Why don all sinks come with predrilled holes?
Most Sinks come pre-drilled with holes for Faucets, so it’s a good idea to shop for your Faucet the same time you are picking out a Sink. Most Two Handled Kitchen Faucets require three holes for the water lines and the spout, and often have an accessory external Side Spray or Soap Dispenser, requiring four holes. Also, check your local codes to find out if you need to install an Air Gap on your Sink for the Dishwasher – it’s a good idea anyway, however it requires its own hole as well.
