The most expensive parts of a kitchen remodel are typically cabinetry, countertops, and appliances, in that order. Custom cabinetry can represent 30 to 40 percent of the total project cost, natural stone countertops another 10 to 15 percent, and integrated luxury appliance packages (Wolf, Sub-Zero, Miele) another 15 to 25 percent. Layout changes that require moving plumbing, gas lines, or electrical add significantly to labor cost.
