Why Elongated Toilets Seat Are Not Universal

Toilet seats usually come in two shapes; elongated and round. While round toilet seats measure 16.5-inch-long, elongated toilet seats primarily measure 85.5-inch-long.

In that case, you cannot replace an elongated toilet seat with a round option or vice versa. Note, however, that since elongated toilet seats come in a standard size (18.5-inch length), you can interchange them.

But How Do You Know That You Have an Elongated Toilet Seat? 

Well, you can know if you have an elongated toilet seat if you determine its size. In particular, measure its length and width and the seat post holes. 

Below is how you can do it:

a) The Seat Length

This is usually the most important measurement that you should determine. While the width and the distance between the seat post holes are typically standard in nearly all seat posts, the length differs in most cases.

While determining the toilet seat length, you should measure the area between the bowl length and the seat post holes. If it is 18.5 inches, then you have an elongated seat. But if it’s about 16.5-inch-long, it’s a round toilet seat.

Also, measure the length from the outside edges of the bowl to get the correct figure which should be 18.5 inches for the elongated seats.

b) The Seat Width

All elongated seats have the same width. To determine the width of your toilet seat, you should measure the area across the toilet bowl. Ensure that you measure the outside edges of the bowl. 

The elongated toilet seat width should be 14 inches. So, if you get a different figure, it could be that you measured wrongly or that you have a non-standard elongated toilet seat, which is quite rare.

c) Seat Post Holes

To confirm a standard toilet seat, you should measure the area between the seat post. Make sure you measure from the center of one seat post hole to the other.

Overall, the distance between the two points should be 5.5 inches.
