Toilet Styles

The toilet is one of the most used and appreciated fixtures in the bathroom. When deciding which toilet is best for your home, here are some helpful ways to search.

Flush Type

The National Energy Act of 1992 required all toilets sold in the United States after January 1994 to use a maximum of 1.6 gallons per flush (gpf).

Another important decision is choosing between a one-piece and two-piece toilet.

One-piece toilets

  • Tank and bowl integrated into one piece
  • Easier to clean
  • Tank is more stable

Two-piece toilets

  • Most popular option
  • Tank and bowl are two separate pieces
  • Typically more affordable

Bowl Shape

Elongated Toilet Bowl


  • Most popular bowl shape
  • Oval bowl shape
  • Typically 18 ½ inches
Shop elongated toilets
Round Toilet Bowl


  • Great for small bathrooms
  • Round bowl shape
  • Typically 16 ½ inches
Shop round toilets
Toilet Bowl Height

Bowl Height

Comfort height toilets are slightly taller than standard toilets, making it more comfortable for average-sized adults and those who have trouble sitting and standing. A toilet with a seat anywhere from 17 to 19 inches tall is considered comfort height, and standard height toilets are approximately two inches shorter.

Other Features

Insulated tank

This option is helpful for homes in high-humidity climates. Insulated tanks help prevent condensation from forming, which can cause premature wear on the surrounding walls and flooring.

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.

Antimicrobial coatings

Just a few manufacturers offer this feature, which give the toilet a smoother finish, keeps it cleaner overall, and makes it easier to clean.

American Standard calls it Everclean; Toto calls is Sanagloss; and Kohler has an anti-microbial agent formed into its seats.

Note: Not all toilets come with toilet seats. Shop Toilets with seats or shop toilet seats.
