Kitchen islands are mainly of the wooden or the stainless steel types. They can be used in the kitchen or they can be of the outdoor type where they can be placed in the backyard or next to the swimming pool for preparation of outdoor meals. Kitchen isles can be made of blocks where each block has a particular function or they can be one big unit that incorporates all the requirements into the structure. One can build simple wooden kitchen islands that have drop leaves to save space.
Include a ventilation hood overhead to eliminate smoke, steam and cooking odors if your kitchen island is going to have a cooktop. The range hood should extend beyond the cooking area by 3 inches or more on the sides for proper ventilation. Using the correct fan size will ensure that removal happens as intended. Have a fan capacity of about 50 cubic feet per minute (cfm) for each square foot of cooktop area.
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.
Pick a countertop for your island that matches your other counters or make it stand out by using a contrasting material. Also, your choice of cabinetry and decorative elements can make your island into a real quality item, similar to a fine furniture piece.
