A second kitchen sink can be included on the kitchen island. Use a sink that is deep enough for washing large pots and pans, and consider equipping the kitchen island with a trash compactor, garbage disposal, recycle bin and even a dishwasher. Cleanup will be much easier when these appliances are close by the sink.
Another alternative is to have a custom island designed just for your needs. Kitchen design experts can help you come up with an island that will fit perfectly into your space and also have all of the components you really want to have. You can add a cooktop, a sink, or even a built-in microwave oven which can free up a lot of your counter space. Both a cooktop and a sink built into an island can help the cook become more a part of the festivities when you're entertaining if the island is used as a room divider between the kitchen and other living spaces.
Home improvement stores offer lines of cabinets that include kitchen islands, so you can design your entire kitchen to match. Stock cabinets contain drawers, cabinets, and bookshelves that are easy to reach, unlike some of your high cabinets. You can store a host of materials in a small area that used to be nothing but wasted floor space. Of course, you don't want to add such a large kitchen island that you make your kitchen impossible to move around in. After all, the idea of adding a kitchen island cabinet is to make your kitchen more efficient, not create traffic jams.
For those remodeling and looking for an "open" feel where perhaps the wall or half wall separating the kitchen and the dining room is taken down, a strategically placed island acts as a subtle room divider mentally separating the kitchen from the dining room but with a much more open feel.
