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.
If you wish to have granite or marble as island top, do ensure that you have invest in a much more studier base that is capable of support the heavy weight of these material. The granite top can have box shape cuts at certain areas to include a sink, a grill and an electric stove. Below the island top one can add pipes to supply water to the sink or electricity to the appliances. The shelves can be polished or painted differently from the top to get a splendid looking kitchen isle.
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.
