The dimensions and placement of your kitchen island will depend on the shape and space available in your kitchen. Professionals say that the island should be positioned at least 36" from existing cabinets and 42" from the range, refrigerator or dishwasher to allow plenty of room for opening doors and easy maneuvering around your workspace area. The height of your kitchen island can vary to suit your individual needs. If you can't make up your mind on that one, a multi-level island might be the solution.
Pick a countertop for your island that matches your other counters or make it stand out by using a contrasting material. Also, your choice of cabinetry and decorative elements can make your island into a real quality item, similar to a fine furniture piece.
We are often asked if the countertop of the island needs to match the existing kitchen countertop in style, or what will be installed as the main kitchen countertop. In most homes I would say it does match, but it really does not have to at all, nor does the material need to be the same. In fact, if you are not going to match them up exactly it's better if it looks like you are not even trying to match them, so using a completely different color and surface is perfectly acceptable.
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).
