toilets

Toilets are the largest single use of water in American homes. In the United States it has been illegal since January 1, 1994, to make toilets for residential use that use more than 1.6 gallons per flush, a restriction extended to toilets for business and industry in 1997. (What do you suppose an industrial strength toilet is?)

Bowls are made in two shapes: round, and elongated.

Height ranges from 18.5 to 38 inches.

The standard “rough-in,” the distance from the wall to the center of the waste pipe in the floor, is 12″; however, 10″ and 14″ rough-ins have also been made.
