In addition to seating 4 (or more), islands today are used to house "luxury" appliances that do not fit in the cabinet structure like a second microwave, second oven, wine refrigerator or even another cooktop. Islands many times are fully wired for electricity and have plumbing for a second sink. The base of an island can be used as a wine rack. The possibilities are almost endless.
The kitchen is the heart of the home and you want it to be a room that is welcoming and cozy for family and guests. But kitchens tend to be busy places and can get messy and cluttered up pretty quickly with all of the appliances and gadgets, not to mention décor items, which can diminish the nice atmospheric state you're going for. One good solution is to install a kitchen island. Not only are they convenient as a means of additional workspace, but many are equipped with their own cabinets and drawers to help you prevent that untidy appearance.
Islands can "float" as well. Smaller islands used primarily as an aid in cooking or baking can be fitted with wheels and moved around the kitchen as needed to aid in cooking. Whether you consider a floating island will probably depend on what you have installed on the floor now, or plan to install (a soft wood will be nicked and scratched).
Budget : Setting a budget out front can be beneficial if you have budget constraints. Having a budget to work on, you can easily adjust the types of material to be used or length of wooden planks to be purchased accordingly before ordering the materials.
