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.
If you have a big island that can accommodate many people, consider using full benches. The benches can be with or without backing to allow for more comfortable seating.
A kitchen island is not a new concept, since they were known back in the medieval days when knights were bold. They are assuming increasing popularity in today's kitchens, particularly in larger homes where the kitchen is more than just a small cooking area compressed into an area somewhere between the dining room and the garden shed!
For those remodeling and looking for an "open" feel where perhaps the wall or half wall separating the kitchen and the dining room is taken down, a strategically placed island acts as a subtle room divider mentally separating the kitchen from the dining room but with a much more open feel.
