Take the opportunity to make your kitchen island mutli-functional because there's lots of options to choose from. Just about any appliance can be built into it including cook tops, under-the-counter refrigerators, sinks, dishwashers and trash compactors. Deep drawers provide a place to store bulky cookware and pullout shelves allow for more easy access.
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.
Space and Design are Important : You need around 3 feet of walking space around the island unit, and you must be sure that the drawers and doors in the cabinets have room to open. If you keep to the 36 inches then you should be OK. The only dimension that must be stated is that of the counter height. Ideally it should be the same as the rest of your kitchen units. If not, then it is not a disaster, but can be disconcerting when you are working on the various surfaces at varying heights.
Your first consideration when deciding on a which type of kitchen island you'd like should probably be how you plan to use it and their functions are as varied as the wide range of design options. They can be a utilized as a food preparation area, a baking center, a serving spot for an informal meal or buffet and the perfect setting to sit and nibble a snack or sandwich. An island even can provide a quiet spot for children to do their homework, close to mom while she gets after school snacks or dinner together.
