Yes. In some cases, a refrigerator against a wall is the best option since the refrigerator door cannot block any pathways. If you do choose to place your fridge against a wall, make sure to leave 21/2" minimum clearance on each side to allow for the door to swing open. How well a refrigerator fits against the wall depends on the door styles as well. A classic one door top or bottom mount refrigerator, like this model from KitchenAid brand, will work best as long as the door opens away from the wall.
