How To Choose a Toilet
The National Energy Act of 1992 required all toilets sold in the United States after January 1, 1994 to use a maximum of 1.6 gallons per flush (gpf).
ConfigurationAnother important decision is choosing between a one-piece and two-piece toilet.
This is the path the waste water travels when leaving the toilet during flush. It provides a liquid seal to prevent any backflow of sewer gas without affecting the flow of sewage and waste water. Trapways can be S-shaped or elbow-shaped.
Soft close seat
This is a fantastic option that’s ideal for households with children. Soft close seats (along with the lid) close slowly to prevent smashing little fingers, instead of slamming down on the bowl.
If your new toilet doesn't include a seat (and many don’t), this is a great option.
