Elongated vs Round Toilets - Which Should I Choose?

Elongated toilets measure roughly 18 inches from the toilet seat mounting holes to the front of the toilet bowl rim. This longer length will require a bit more space in your bathroom than a round model would. Standard toilet heights are usually 14 or 16 inches, with chair-height toilets ranging from 16 to 19 inches. The rough-in measurements, the distance between the wall behind the toilet and the center of the drainpipe or the bolts that hold the toilet to the floor, are either 10, 12 or 14 inches. Compact elongated toilets have the larger shape of an elongated toilet but can fit in the space of a round toilet. These toilets require an elongated toilet seat.

Elongated toilets can come in either one- or two-piece units. One-piece units are, like the name implies, a single piece for installation. One-piece units are easy to install and keep clean. Two-piece units have a separate bowl and tank, where the bowl is mounted first and then the tank is installed on the back of the bowl. Flush technology can be gravity fed or a more powerful pressure-assisted flush. There’s also a dual-flush option to save water.

Round toilets measure about 16-1/2 inches from the mounting holes to the front of the toilet bowl rim. This shorter bowl size is great for smaller bathrooms. The rough-in sizes and seat heights are the same as for elongated toilets. One unique option for a round toilet is a children’s-height model. This kind of toilet is designed with a toilet height of 10-1/4 inches, making it perfect for potty training or installing at preschools and day cares.

Round toilets also come in either one- or two-piece construction. However, the majority of models are two pieces. Flush technology is either gravity fed, pressure assisted or flush valve. Round toilets will need a rounded toilet seat.

The main difference in these toilets is the shape. They both have similar heights, rough-in sizes and flush technologies. So what are some of the differences that should figure into your choice for your bathroom?

• The larger shape and look of an elongated toilet may make it preferable to many people, especially larger and taller individuals.
• Elongated toilets can have a more powerful flush system, which may prevent the need to “double flush.”
• Elongated toilets require more room than a round toilet, so take this into consideration if space is an issue.
• It’s possible to install a round toilet for potty training and then replace it with an elongated model as your child grows up. .
• Elongated toilets may be more expensive to purchase than a round toilet.
• Toilet seats for elongated toilets may be easier to find when you’re looking for a replacement.

ADA-compliant toilets can resemble regular or standard toilets, but there are several characteristics that make them different. These special toilets meet requirements from the Americans with Disabilities Act for proper height, toe clearance, flush handle position and flush technology.

ADA-compliant toilets are taller to help those who may have trouble sitting on or rising from a lower-height toilet. These taller toilets are also known as comfort-height toilets. Another important consideration for an ADA-compliant toilet is the flush handle. It should be located within easy reach while also being easy to engage without putting a strain on the hand or wrist.
