Kitchen costs vary more than any other room because they're driven by structural work, not just furniture and décor. A cosmetic refresh (new hardware, paint, lighting) can run $1,000–$5,000. A mid-range renovation with new cabinets, countertops, and appliances typically lands at $5,000–$20,000. A high-end renovation with custom cabinetry, premium stone, and a full layout change can exceed $60,000.
