What Does a Full Renovation Cost? Complete Price Guide for 2026

A full home renovation is a major investment, and it is natural to wonder what it actually costs. Prices vary greatly depending on the size of the home, its condition, and the materials you choose. As a rough rule of thumb, a full renovation of an average detached house of 120-150 square meters costs between NOK 1.5 and 3.5 million. For apartments of 60-80 square meters, prices typically range from NOK 800,000 to 1.8 million. The largest cost items in a full renovation are usually the bathroom and kitchen. A new bathroom typically costs between NOK 250,000 and 500,000 depending on size and material choices. A kitchen including cabinetry, appliances, and installation usually comes to NOK 200,000 to 450,000. In addition, electrician and plumber work can account for 15-25 percent of the total budget. Flooring, painting, and surface treatments typically make up 10-15 percent. An important tip is to always set aside a buffer of at least 10-15 percent of the total budget for unexpected costs. When renovating older homes, hidden problems such as moisture damage, asbestos, or poor insulation can appear when walls and floors are opened up. At Ski Bygg, we always provide a thorough condition assessment before we start, so you get the most realistic cost estimate possible from the beginning. When planning a full renovation, it is wise to prioritize what provides the most value. Upgrading the bathroom, kitchen, and energy efficiency typically provides the best return on a potential sale. Cosmetic changes like painting and new floors are relatively affordable but have a big visual impact. We recommend creating a priority list together with the contractor, so you can adapt the scope to your budget. At Ski Bygg, we offer full renovations with fixed pricing where possible.
