How to Measure Elongated and Round Toilets?

It is not difficult to determine if a toilet has an elongated or circular shape, but it is worth double-checking. This could be a great help if you need to replace a toilet seat. You won’t have to buy the wrong size.

When measuring the dimensions of a toilet, you must know three dimensions that are important. These dimensions are the bolt spread, width, and length. The most important dimension is however the length.

The bolt spread dimension in the United States is usually 5.5 inches. The bowl’s thickness determines the toilet bowl’s width. Measure your toilet bowl starting at the center to get the exact dimensions.

The distance between the center of the toilet seat holes (the middle) and the bowl’s front is called the length. First, remove the toilet seat. Place the tape measure’s edge in the middle of each hole. Next, stretch the tape measure towards the bowl’s front. The longest toilet bowls are usually oval-shaped with a length of around 18.5 inches. Round toilet bowls have a circular shape and a length of approximately 16.5 inches.

Comparison of Elongated And Round Toilets

Let’s now look at the differences between round and elongated toilets. This will help you to choose the best unit for your bathroom.

Requirements for Regulation

Before installing your toilet in a municipal space, there are certain regulations you must follow. The minimum distance between your toilet bowl and the front door of most public buildings is 21 inches. It must be at least 21 inches from the front door if it is an ADA-compliant toilet. The toilet bowl should also be at least 48 inches from the front wall. If you have a small bathroom, the round toilet is best.


Elongated toilets are 2 inches shorter than round toilets. Round toilets measure 16.5 inches in length, while elongated toilets measure 18.5 inches. It is therefore impossible to replace an elongated toilet seat with a circular one. An elongated toilet, on the other hand, can be replaced by a round one. This is possible by ensuring that the rough-in measurements are identical. You can choose low-profile designs in terms of overall height.

Bathroom Space

For those with small bathrooms, round toilets work best. These toilets are great for children’s bathrooms. If your bathroom is large enough, you can opt for an elongated toilet.

Luckily, the current toilet manufacturers produce elongated toilets which take up less space than the traditional round toilets. The comfort and rough-in dimensions of these elongated toilets are the same as ever.


An elongated brand is more expensive than a round brand that has similar specifications and features. Price is not only determined by the toilet’s shape but also by many other factors. However, regardless of whether the toilet is round or elongated, plumbers usually charge the same amount for installation.

Traditional vs. Contemporary Designs

Elongated toilets may look modern, but round toilets can still be considered traditional. Elongated toilets tend to be more popular in newer homes. Round toilets are more prevalent in older homes. Most people agree that round toilets look better than oval toilets.

Because of its length, an elongated toilet is easier to clean than a normal toilet. This is not a major factor, but it is worth considering.


This is perhaps the most important turning point for many of our clients. A longer toilet is more comfortable than a standard round one. Because of its length and shape, it offers a large area that is convenient for many people. Children prefer round toilets over elongated ones, as they are less likely to fall into the large bowl.
