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.
A kitchen island is not a new concept, since they were known back in the medieval days when knights were bold. They are assuming increasing popularity in today's kitchens, particularly in larger homes where the kitchen is more than just a small cooking area compressed into an area somewhere between the dining room and the garden shed!
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.
Kitchen islands work best in larger L, U or G-shape kitchens. If the kitchen is too small, the kitchen island will become an obstruction and hinder easy movement. The best custom kitchen islands for small to midsize kitchens are a portable butcher block or kitchen cart for food prep or extra storage.
