SIZE is important when you're buying a seat.
Measure your toilet to determine whether your bowl is

  • elongated (approximately 18 1/2" long)
  • round (approximately 16 1/2" long.)

Measure from center front of bowl to center of the hinge post holes. In the U.S., the standard distance between hinge post holes is 5 1/2".
