If you have doubts, you could always ask a professional designer to go over your kitchen space and make a recommendation or, if you want to save money, you could visit friends who have a kitchen islands and make the necessary comparison. Moreover, you can choose for your kitchen island to be in an L, U, or a G shape.
What can we expect to pay for an island during a remodel? This one is too hard to answer because there are simply too many choices. A "ready to install" stock island you can purchase in a home store with connections for drainage and power can run about $800. A custom concrete countertop island with sink, cooktop, and wine refrigerator can easily eclipse $10,000.
You may only have a limited space and you think that seating will only make your kitchen look crowded. However, it does not mean that you can't have seating. For a room with limited space, you can use smaller stools. To save space, you can also choose chairs that you can store in a closet when you do not need them.
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.
