You may be wondering if toilet seat sizes are universal. Today, there are two standard toilet seat sizes. Round toilet seats are 16.5 inches long, while elongated toilet seats measure 18.5 inches in length.
Toilet Seat Types
Let’s look at the specific details of round toilet seats compared to elongated toilet seats below.
Round Toilet Seats
Round toilet seats are about 16 inches long and 14 inches wide. This style of toilet seat is far more popular in homes. They take up less space than elongated seats, making them ideal for small and midsized bathrooms.
Because these seats are smaller than elongated seats, they are also the cheaper option for homeowners.
Elongated Toilet Seats
Most elongated toilet seats measure about 18 inches long and 14 inches wide. These seats are often used by airports and hotels.
While they are most commonly found in large businesses, homes and apartments do utilize these seats, as well.
Are Toilet Seat Sizes Universal?
Not all toilet seats are universal, as there are two popular options used today, as previously discussed. The distance between the two bolts responsible for holding the seat to the bowl is standard across nearly all toilet types. These seat post holes need to be about 5.5 inches apart from the center of one hole to another.
The toilet bowl width is typically the same regardless of shape. If the width does vary, it will only be by half an inch.
