The kitchen faucet and garbage disposal are installed by the plumbers after the counter and sink is put in place.   There are many different styles, colors and types of faucets available to you that can suite virtually any need.  We chose a faucet with a detachable spout for easy cleaning of dishes and washing of produce.  Some options include sprayers on the side of the sink,  built in soap dispensers and purified water dispensers, all attached to the base of the faucet unit.   Another important feature, the garbage disposal, is plumbed in to the drain line.
