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.
A second kitchen sink can be included on the kitchen island. Use a sink that is deep enough for washing large pots and pans, and consider equipping the kitchen island with a trash compactor, garbage disposal, recycle bin and even a dishwasher. Cleanup will be much easier when these appliances are close by the sink.
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.
Mind Your Head : If you are hanging anything from the ceiling, make sure that there is sufficient clearance so that people do not bang their heads on a skillet or frying pan! Clearance is all-important with kitchen islands, because there is not a lot worse than having a kitchen that is severely restricted in space just to accommodate an island. The island should complement your kitchen, not dominate it.
