There are numerous factors which influence the cost of a kitchen refurbishment. Whether you use custom made cabinetry of flat pack options is one of the main differences, but size, finishes and appliances also play a part. High-end kitchens can cost over $50,000 whereas smaller kitchen makeovers can be done for $10,000 to $15,000 if you’re using lower end materials and finishes. $20,000 to $40,000 is the medium range which the average reno falls in.
