There are three basic types of refrigerator:

• Top freezer with bottom refrigerator
• Bottom freezer with top refrigerator
• Side-by-side freezer and refrigerator
  

The top-freezer model is the least expensive and tends to be the most roomy. The bottom-freezer unit allows easier access to the refrigerator but you can’t put a built-in ice-and-water dispenser in it. The side-by-side offers easier access to both compartments. It’s not as energy efficient, though, as the other two and its compartments can feel annoyingly narrow.
