A: Freestanding refrigerators are finished on the sides and can be placed anywhere you have the space. These units can be purchased in different finishes and a wide variety of features and space saving interior solutions. Built-in refrigerators are custom-fit to cabinets and are not finished on the sides. They are counter or cabinet depth to ensure either a proud mount or flush mount look. These units traditionally boast larger more technologically advanced compressors, advanced humidity and cooling systems and the option to custom fit.
