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.
Know how much space you have. If you have a large kitchen island, then you can use full size chairs. For home owners who only have a smaller one, they may only use two seats. You should also decide the space that your guests can have. Sometimes, kitchen islands are merely used for decorative purposes rather than practical seating. So if you want to add seats, you should make sure that you have enough space in your kitchen for them.
Countertop material for the island doesn't have to match the rest of your kitchen countertops as long as it is harmonious with the room's overall design. You may want to splurge on solid surfacing here, for example, and use laminate on the other countertops. A butcher-block countertop is ideal for chopping, while granite or marble works well for baking purposes and for rolling pastry dough.
Another problem you might face if you buy your kitchen island as a separate unit, and not as part of the overall kitchen, is matching it to your existing cabinets. This might not be as easy as your think, but if you purchase a solid color, such as black, white or red, then you should get away with it.
