Round vs Elongated Toilet Seat

Round vs Elongated Toilet Seat: Differences Explained

Round and elongated toilet seats are two common types of toilet seats that are available on the market. While both types offer comfortable and practical seating solutions, there are some key differences between them.

Rund toilet seats are circular, while elongated toilet seats are oval-shaped. Elongated toilet seats are generally longer than round toilets, measuring 18.5 inches (47 cm) in length compared to 16.5 inches (42 cm) for round toilets. The extra length provides additional comfort and support.

You’re probably considering the type of toilet seat that will best fit into your bathroom. The rest of this article will explain the main differences between round and elongated toilet seats so you can make an informed decision when choosing one for your home.

Round vs Elongated Toilet Seat Comparison

While round and elongated toilet seats provide comfortable seating solutions, some key differences between them can make a difference in your decision-making process. 

Here are some of the main things to consider:


Round toilet seats are circular in shape and are typically smaller in size compared to elongated toilet seats. They are commonly used in small bathrooms or powder rooms where space is at a premium.

Elongated toilet seats are oval-shaped and are longer than round toilet seats. They are more common in larger bathrooms and are often preferred for comfort and added support.

The shapes of elongated and round seats can influence the overall look of your bathroom. A round seat might be better suited to that look if you have a traditional style. However, if you prefer a more modern look, an elongated seat will be the better option as it provides a cleaner, sleeker appearance.


Elongated toilet seats tend to be larger than round ones, and this can be beneficial if you have a larger frame or need more room to move while sitting on the toilet. These seats are 18.5 inches (47 cm) in length and 14.5-15 inches (37-38 cm) in width, making them more comfortable for people with larger frames, mobility issues, or disabilities.

Round toilet seats have a smaller opening and are 16.5 inches (42 cm) in length and 14-15 inches (36-38 cm) in width. This size can be more suitable for smaller bathrooms, children’s bathrooms, or if you don’t need much space to move while sitting on the toilet.


Both toilet seats are easy to install and can usually be done in a few minutes. Round toilet seats have a universal design, so they can fit most toilets and come with all the necessary parts and tools for installation.

Elongated toilet seats can either be one- or two-piece and will require different tools and parts depending on the type of toilet you have. It is important to ensure you are purchasing the right seat for your particular toilet model.

The toilet bowl also needs to be considered when selecting a seat. Round toilet seats are best suited for round-shaped bowls, while elongated seats are better for oval or oblong bowls. However, some manufacturers make toilet models that can accept both types of seats, so double-checking the measurements before making your purchase is always a good idea.


Round toilet seats are usually less expensive than elongated seats, as their design is simpler and does not require additional materials or components. Elongated seats come in a wider range of styles and materials, typically costing more than round ones.

The manufacturer and style of the seat will also influence the price. Some brands are more expensive than others, and certain materials, such as wood or special finishes, can add to the overall cost of the seat. So it’s important to compare prices and styles before making your final decision.

Maintenance and Cleaning

Round and elongated toilet seats are generally easy to clean and maintain with regular wiping down using a damp cloth or an all-purpose cleaner. However, the extra length of an elongated seat makes it easier to clean around the edges, as there is less chance of dirt and debris getting caught in the crevices.

Round toilet seats are less likely to collect dirt and grime due to their smaller size but still require regular cleaning to keep them looking their best. This is an important factor to consider if you have a primarily white or light-colored bathroom that will show dirt and grime more easily.

No matter which type of toilet seat you choose, regular cleaning and maintenance are essential to keep your bathroom hygienic and looking its best. Both types of seats are available in various materials, so selecting one suitable for your environment and lifestyle is important. Some materials will require more intensive cleaning and maintenance than others.


The more traditional look of a round toilet seat will be suitable for older-style bathrooms, while modern and contemporary designs often feature the sleeker look of an elongated seat. Additionally, there is a wide range of colors, materials, and finishes to choose from to match the style of your bathroom.

Round toilet seats have a more classic look, while elongated ones can provide a modern touch to any bathroom. Both types are available with different hinges and lid styles, such as soft close or quick-release mechanisms, so it is important to consider the kind of seat that best suits your needs.


Overall, both round and elongated toilet seats provide a comfortable seating experience. The difference in the length of the seat can affect the amount of space you have to sit, however. Elongated seats are usually more spacious and provide more room for larger users or those with mobility issues. On the other hand, round seats offer a more compact sitting area that can be better suited for smaller bathrooms or users.

It is also important to consider the contour and shape of the seat. Many modern models feature ergonomic designs that provide extra support and comfort. Some seats also have additional features, such as soft-close hinges that make them more comfortable.

Flushing Performance

The elongated shape of an elongated toilet seat may provide slightly better pressure when using a flush that circulates the water in the bowl using force.

However, when used with other flush technologies, there may not be a huge difference between the two. The optimal flushing performance of a toilet is determined by the type of bowl and flush mechanism, so it is important to consider these factors when choosing your new seat. 

9. Aesthetics

Regarding aesthetics, round toilet seats may not be as pleasing to some people as elongated seats. This is because they tend to look more traditional or utilitarian, while elongated seats have a more modern or streamlined appearance that can be better suited for contemporary bathrooms.

If the appearance of your toilet is important to you, you may prefer an elongated seat. But, it is important to remember that the shape of your toilet seat has no bearing on its performance or comfort, so you should select the one that best meets your needs and preferences.

Pros and Cons of Round and Elongated Toilet Seats

Round and elongated toilet seats have their own set of pros and cons, and the right choice for you will depend on your personal preferences and the specific needs of your bathroom.

Round Toilet Seats


  • Compact size. A round seat may be the better choice if you have a small bathroom, as it will take up less space. This can be especially useful if you have limited room around your toilet or need to fit multiple fixtures in a small area.
  • Traditional look. Round toilet seats will usually fit better with older-style bathrooms or any decor that prefers a classic look. You can also find modern-looking models that still retain a traditional style and feel.
  • Cheaper. Round toilet seats are usually less expensive than elongated seats. If you’re on a tight budget or looking for an affordable way to update your bathroom, this can be a deciding factor.
  • Comfortable for kids. The smaller size of a round seat makes it easier for young children to use. Kids don’t have to stretch out their legs as far and can sit down and get up more easily.
  • Durability. The simpler design of round seats can provide outstanding durability over time. However, choosing a model made from quality materials and solid construction is important.


  • Less comfortable for adults. Round toilet seats provide less support for the thighs, which can lead to discomfort or even pain during prolonged periods of sitting. If you have back or joint issues or spend much time on the toilet, an elongated seat may be a better choice.
  • Limited options. Round toilet seats are usually more limited in terms of colors, materials, and finishes than elongated ones. If you’re looking for a specific type of style or design, you may want to consider an elongated seat instead.
  • Old design. Round toilet seats have been around for quite a while and may not fit in with modern decor. An elongated seat may be a better choice if you want to create an updated look.
  • Harder to clean and maintain. Since round toilet seats are usually made from a single piece of material, it can be challenging to get into the crevices and grooves for thorough cleaning. You’ll have to be more meticulous and use special tools to get into those hard-to-reach areas.

Elongated Toilet Seats


  • Sleek design. Elongated toilet seats are usually more modern and stylish, which makes them an attractive choice for contemporary bathrooms. You can find a variety of colors, materials, and finishes to match your decor.
  • More comfortable for adults. Since the seat is more extended, it provides more support to the thighs and can be much more comfortable for adults during extended periods of sitting. The extra length also makes it easier for taller individuals to sit down and stand up.
  • More cleaning options. The design of elongated toilet seats makes it easier to get into crevices and grooves with a brush or other tool. This allows for more thorough cleaning and less hard-to-reach areas, making maintenance much more straightforward.
  • The better choice for a large bathroom. The larger size of the elongated seat makes it more suitable for larger bathrooms. This is especially helpful if you want to create a cohesive look or need more room around the toilet area.
  • More options to choose from. You can find a wider selection of elongated toilet seats in terms of colors, materials, and finishes. This gives you more flexibility when it comes to finding the perfect seat for your bathroom.
  • Additional features. Many elongated toilet seats have added features, such as slow-closing lids, heated seats, and adjustable heights. These can provide more convenience and comfort, making them an ideal choice for those who want extra amenities.


  • Expensive. Elongated toilet seats tend to be more expensive than their round counterparts. If you’re dealing with a limited budget or just looking for an affordable solution, this can be a deciding factor.
  • Limited use for small bathrooms. Some smaller bathrooms may not have enough space to accommodate an elongated seat. If this is the case, you’ll want to opt for a round seat instead.
  • Not suitable for kids. The larger size of the seat can make it difficult for young children to sit down and get up. This could be a safety issue, so choosing a round seat is best if you have small children in your home.
  • Harder to install. The elongated shape can make the installation more challenging, especially when dealing with tight spaces. This is something to keep in mind if your toilet area is not easily accessible or if you’re not a DIYer.

Choosing the Right Toilet Seat for Your Needs

You must consider your needs and preferences when deciding on a suitable toilet seat. Both round and elongated seats offer their own set of advantages and disadvantages, so it’s important to weigh all the factors before making your final decision.

There are some considerations to keep in mind when making this decision:

  • Size of Your Bathroom. Round toilet seats are more suitable for smaller bathrooms, while elongated seats are better for larger spaces. Measure the area around your toilet and compare it to the seat size before purchasing to ensure a proper fit.
  • Budget. Round seats are typically more affordable than their elongated counterparts, so consider the cost when making your purchase. If you’re on a limited budget, opting for a round seat might be the better choice. However, the manufacturer and quality of materials can also play a role in the price, so shop around to get the best deal.
  • Comfort and Convenience. Think about who will be using the toilet and their needs. Elongated seats are more comfortable for adults, while round seats might be a better choice if you have small children in your home. Additionally, many elongated seats come with additional features such as slow-closing lids and adjustable heights – something to keep in mind if you’re looking for extra amenities.
  • Cleaning. Elongated seats are easier to clean due to their shape, making maintenance much simpler. Consider this when deciding if you plan on doing a lot of cleaning in your bathroom or have limited time for upkeep.
  • Design. Elongated toilet seats offer more options in terms of colors, materials, and finishes if you want to create a cohesive look in your bathroom. This can be an advantage if you’re looking to match the look of your toilet with other pieces in the room.
  • Toilet height. Measure the height of your toilet before selecting a seat to ensure you get a compatible one. Elongated seats are usually available in multiple heights, while round seats come in standard heights. However, you can also opt for an adjustable seat if you’re looking for a better fit.
  • Flush volume. Elongated toilets tend to have a higher flush volume than round ones, so if you’re concerned about water efficiency or looking for better performance, this is something to keep in mind.
  • Type of flush. There are different types of flushes, such as in-wall, dual-flush, single-flush, and wash-down. Depending on your toilet, some of these options may be more compatible with one type of seat than the other, so consider this before making your purchase.


Overall, the choice between a round and elongated toilet seat comes down to personal preference and the specific needs of your bathroom. A round seat may be the right choice if you have a small bathroom and are looking for an affordable, easy-to-clean seat.

On the other hand, if comfort and convenience are your main priorities, you might want to opt for an elongated seat. Consider all the factors before making your decision, and remember to measure and compare different models before purchasing.

You can make your bathroom a more comfortable and inviting space with the right seat. Good luck with your purchase!
