Many islands are fitted with burners and sinks with a hot and cold water supply, but this is not essential if you already have a traditional sink and stove. There are many different designs of pot hooks or racks that can be used on or above your island. Many people fit hooks to the ceiling to hold cooking pans of different types, but that will depend on the height of your ceiling.
One of the biggest pluses about kitchen islands is that most of them contain extra storage space for all of the paraphernalia that is so necessary in a kitchen today. A kitchen island cabinet can be just the solution to the problem of "Where am I going to put that?"
For example, we have seen islands of concrete when the rest of the kitchen countertop is made of granite or another material. We have seen a black island used as a nice "dividing wall" to keep the kids away from a white kitchen.
Regarding colors and designs, kitchen islands can be made from a number of different materials. The framework is usually wood, but the main visible surfaces could be metal or even stone - granite is a popular substance used for counter tops. Stainless steel is also good, but try to avoid aluminum if possible, because that is very soft and easily cut and scratched, and the metal oxidizes to a dull finish.
