Here are some other interesting White House statistics: it has 132 rooms, 412 doors, 147 windows, 28 fireplaces, 8 staircases, and 3 elevators.
For more information about the history of plumbing in the White House (which is more interesting than it sounds), check out White House Plumbing, from the July 1989 issue of Plumbing and Mechanical magazine.
