When it comes to kitchen islands, we generally think of additional storage, preparation and serving space in the kitchen. But the fact of the matter is that kitchen islands can waste a lot space. Choosing the wrong island or placing it in the wrong spot can be a disaster, especially in a work area that can get cluttered. Islands that obstruct the flow of traffic to and from the sink, refrigerator, stove and primary workstations will create bottlenecks and major hassles. At minimum, an island should be 4 feet long and a little more than 2 feet deep, but it must also have room for people to move and work around it. Experts say that unless the kitchen is at least 8 feet deep and more than 12 feet long, one shouldn’t even consider an island.
