The cost of flooring depends on whether you're replacing a few cracked tiles or doing a complete overhaul of your existing flooring. If you're opting for the latter, the price will depend on your kitchen's square footage and the flooring material you've chosen. Vinyl is generally the most affordable option. While ceramic tile, laminate, cork and hardwood tend to cost more, they can also increase your home's value.
If you want more counter and storage space, then adding a center island may be worth the cost. But an island can limit the number of people working in the kitchen, reduce traffic flow to one-way with no passing, and make for cramped quarters. Try out an island before committing to one. Slap together a full-scale model out of cardboard or plywood and live with it for a few days. Make sure you can open your stove and refrigerator doors. No space for an island? Consider a kitchen trolley instead.
