In interior design, the terms small, medium, large and huge are used a great deal.

But what do those terms actually mean for each room in terms of sq. ft.  Obviously, the square footage for each size category will vary room-to-room.  A small kitchen is larger than a small bathroom.  In fact, a small kitchen would be as big as a large or huge bathroom.

This article sets out to actually define exactly what the different bathroom sizes are in square footage.  We then set out what size is the most popular based on frequency.  This information is hopefully helpful with your bathroom remodelling project.
