Can You Put an Elongated Toilet Seat on a Round Toilet? (2024)

Elongated (or oval-shaped) toilet seats are widely used in homes and public spaces and are more comfortable than their round counterparts. If you have a round-shaped toilet, you might wonder if you can fit an elongated toilet to it. Is this possible?

You can put an elongated toilet seat on a round toilet. However, the fit won’t be secure because the shape won’t correspond with that of the bowl. The seat may become unstable over time and may not provide a comfortable seating experience due to the misalignment between the seat and bowl shape.

The rest of this article will discuss a few topics related to elongated toilet seats on round toilets. These include how to fit an elongated toilet seat on a round toilet, the drawbacks of doing so, and some general tips for choosing the right seat.

How To Fit an Elongated Toilet Seat on a Round Toilet

Fitting an elongated toilet seat on a round toilet is a relatively simple process that can be completed in just a few minutes with the right tools.

If you want to fit an elongated toilet seat on a round toilet, here are the steps you can follow to get the job done quickly and easily:

1. Gather the Right Tools

To fit an elongated toilet seat on a round toilet, you will need the following:

Screwdriver. You will need a screwdriver to loosen and remove the bolts that hold the old seat in place and secure the new seat. A flat-head screwdriver or a Phillips-head screwdriver should work for most toilet seats.
Wrench. If the bolts on your toilet seat are tightened with a nut, you may need a wrench to loosen and remove them. A socket wrench or an adjustable wrench should work for most toilet seats but ensure you have the right size for the nuts on your seat.
Measuring tape. Before purchasing a new seat, you should measure the distance of the mounting holes from each other to ensure that the one you buy will fit your toilet. You should also measure your toilet bowl, as this will help ensure a secure fit.
New elongated toilet seat. Ensure you have the new elongated toilet seat on hand before beginning the installation process. When buying one, make sure that it corresponds to your toilet bowl’s shape and size. Some of these toilet seats come with bolts and nuts included, while others may require you to purchase these separately, so check before beginning the installation process.
Toilet bowl cleaner. It is a good idea to clean the toilet bowl before installing the new seat to ensure it fits properly and stays in place. A toilet bowl cleaner and a scrub brush can help remove any dirt or stains from the bowl, leaving it clean and ready for the new seat.

Overall, you will need a screwdriver or a wrench, a measuring tape, and the new elongated toilet seat to install an elongated toilet seat on a round toilet. In addition, you might consider cleaning the toilet bowl with some toilet cleaner and a brush before you install the seat.

2. Measure the Toilet Bowl

Measuring the toilet bowl is essential to ensure that you get the right size and shape for the elongated toilet seat, and is arguably the most important step.

The best way to do this is to measure the distance between the mounting holes of the old seat.

The mounting holes are used to attach the seat to the toilet bowl. These holes should be located at the same distance apart on the new seat as on the old one. If the mounting holes on the seat do not align with those on the toilet bowl, the seat will not fit properly.

To measure the distance between the mounting holes:

Using a measuring tape, measure from the center of one hole to the center of the other on both the old and new seats. Ensure you get an accurate measurement so the new seat will fit correctly.
Record the measurements for use when purchasing a new seat to ensure it will fit your toilet.
Compare the measurements of the old and new seats to ensure they match. If they do not, the new seat will not fit correctly. If they do, the seat should fit properly when installed.

Elongated toilet seats are widely available, and you’ll be spoilt for choice regarding shape, size, and even color. However, taking measurements beforehand is vital so that you buy the correct shape and size. Some toilets are not perfectly symmetrical, so measuring is the only way to guarantee a proper fit.

You can also measure the length of the toilet bowl from the back of the rim to the front and its width from side to side to ensure that the seat will fit correctly when installed.

To measure the length of your toilet bowl:

Place a measuring tape at one end of the bowl and stretch it to the other, ensuring it is level and straight.
Measure from the very front of the bowl to the very back, not including the lip or flange.
Take a note of this measurement as it will help you buy the correct-sized toilet seat.

To measure the width of your toilet bowl:

Place the measuring tape along one side of the bowl and stretch it across to the other side. Again, ensure the tape is level and straight.
Measure from one side of the bowl to the other, not including the lip or flange.
Record this measurement to help you determine the appropriate toilet seat size.

Once you have your length and width measurements, compare them to the size of the toilet seat you are considering purchasing. Most elongated toilet seats have the following standard measurements:

Length: 18 inches (45 cm)
Width: 14 inches (35 cm)

On the other hand, round toilet seats typically have these standard measurements:

Length: 16 inches (40 cm)
Width: 14 inches (35 cm)

If your measurements are significantly larger or smaller, you may need to purchase a different size seat.

3. Remove the Old Seat

Once you have determined the size of the new toilet seat, you can begin to install it. Start by removing the old seat.

To remove the old toilet seat:

Gather your tools. You will need a screwdriver or a wrench to remove the bolts that hold the seat in place before replacing it.
Turn off the water supply. Locate the water supply valve for the toilet and turn it off to prevent water from flowing into the tank while you work. This will also help to avoid water damage to the floor during installation.
Flush the toilet: Flush the toilet to empty the tank and make it easier to access the bolts. You will also want to remove any water from the bowl before you get started to avoid spills and splashes.
Locate the bolts: The bolts are typically located on the underside of the seat, near the front and back of the bowl. You should be able to access them with a screwdriver or wrench.
Loosen the bolts: Use a screwdriver or a wrench to loosen and remove the bolts from the toilet seat by turning them counterclockwise. If the bolts are tightened with a nut, you may need a wrench to loosen them.
Remove the seat: Once the bolts are loosened, you should be able to lift the old seat off the toilet bowl. If the seat is stuck, you may need to wiggle it back and forth gently to loosen it before lifting it off.
Dispose of the old seat: Once the old seat is removed, you can dispose of it according to your local waste management guidelines. If the seat is made of recyclable material, it may be eligible for recycling.
Clean the toilet: Once the old seat is removed, use a toilet bowl cleaner and a scrub brush to clean the area where the new seat will be installed. This will ensure that the new seat fits properly and stays in place in its new home.

4. Install the New Seat

Place the new elongated seat on top of the toilet bowl, aligning the holes in the seat with the bolts on the toilet. Secure the seat by tightening the bolts using a screwdriver or a wrench, then replace the caps on the bolts, if applicable.

Once the new seat is securely in place, turn the water supply back on and flush the toilet a few times to ensure everything is working correctly. You may need to adjust the bolts slightly if there are any leaks.

If the seat feels too loose or tight, you may need to adjust the bolts to get the desired tension. Tighten or loosen the bolts as needed until the seat feels secure but not too tight.

The Downsides of Installing Elongated Toilet Seats on a Round Toilet

While elongated toilet seats offer a more comfortable and spacious seating experience, there are a few downsides to consider before installing one on a round toilet.

Here are some potential drawbacks to be aware of:

Incompatibility with round toilet bowls: Elongated toilet seats are designed for oval-shaped toilet bowls and may not fit appropriately on round toilet bowls. You may find that the elongated seat is too long or wide or that the mounting holes do not align with those on the toilet bowl. When this happens, the seat can be wobbly and poor fitting, and feel uncomfortable and unstable when you use it.
Increased risk of damage: Installing an elongated seat on a round toilet increases the risk of damage. Not aligning or securing the toilet seat properly can result in the bowl breaking or cracking, costing you a lot of money. Additionally, an elongated seat’s added weight and size may put more strain on the toilet bowl and mounting hardware, potentially leading to damage over time.
Aesthetically unpleasing: Depending on the size and shape of your toilet, an elongated seat may not look as aesthetically pleasing as a round seat. If your new toilet seat is larger and wider than the toilet bowl, it can look out of place, messy, and unattractive, negatively affecting the look of your bathroom.
Limited seat options: Finally, if you install an elongated seat on a round toilet, you may have limited options regarding seat styles and features. Most elongated toilet seats are specifically designed for elongated or oval-shaped bowls, and may not be compatible with round toilets. This could limit your ability to find a seat that meets your specific needs and preferences.

Making Your Elongated Toilet Seat More Comfortable

If you do opt to install an elongated seat on a round toilet, there are a few modifications you can make to ensure it is as comfortable as possible. Here are some suggestions:

Add a toilet seat cushion: Toilet seat cushions are a simple and effective way to make your elongated seat more comfortable. These cushions are made of soft, padded material that can be placed on top of the seat to add extra cushioning. They are available in various colors and styles to match your bathroom decor and can be easily removed for cleaning.
Install a slow-close seat: If you’re tired of the loud slamming sound that often accompanies a toilet seat, consider installing a slow-close seat. These models close slowly and gently, and don’t make a sudden or loud noise when they hit the toilet bowl.
Consider a heated seat: For added comfort during colder months, a heated toilet seat can be a welcome addition to your bathroom. These seats are equipped with a heating element that warms the seat to a comfortable temperature, making it more pleasant to use in the morning or after a long day.
Install a bidet seat: For a more luxurious bathroom experience, consider installing a bidet seat on your elongated toilet. These seats have a built-in bidet system that allows you to clean yourself with a gentle stream of water after using the toilet. Many models also include additional features like heated water, air drying, and deodorization to enhance comfort.
Choose a seat with adjustable height: If you have difficulty sitting down or standing up from the toilet, a seat with adjustable height can be a helpful modification. These seats allow you to easily adjust the height of the seat to a level that is most comfortable for you, making it easier to use the toilet with ease.

Tips for Choosing the Right Toilet Seat

Given all the considerations above, it is important to take time when selecting a toilet seat.

Here are some tips to keep in mind:

Consider your bathroom décor: If you’re looking to update your bathroom, you may want to choose a toilet seat that matches the style and color of your bathroom. Luckily, you’re spoilt for choice and you have various toilet seat styles to choose from. Whether you want a modern and sleek design, or something unobtrusive, you’re sure to find it.
Think about your budget: Toilet seats can range in price from under $20 to several hundred dollars, so it’s important to consider your budget before making a purchase. Costly toilet seat models typically have better features and consist of superior-quality materials. However, a more inexpensive option can still offer you what you need.
Consider the seat material: Do you want a wooden, plastic, or composite toilet seat? Plastic is typically the most affordable and easiest to clean, but not as durable as wood or composite seats. Wood seats are more traditional and comfortable, but need more upkeep. Composite seats are often more durable and resistant to wear and tear than plastic or wood seats.
Look for features that suit your needs: If you’re looking for additional comfort and convenience, look for a toilet seat with features like slow-close, heated seats, built-in deodorizers, adjustable height, and a built-in bidet system. These features can help make your bathroom experience more enjoyable.
Consider the seat size: Toilet seats come in standard sizes, but if you have a larger or smaller toilet, consider a different seat. Before looking for a toilet seat, have your toilet bowl’s measurements on hand.
Look for a secure mounting system: Make sure the toilet seat you choose is equipped with a secure mounting system and comes with the necessary hardware for installation. If you decide to go with an elongated seat, check the mounting system to ensure it can support the extra weight of the seat.

Conclusion

You can put an elongated toilet seat on a round toilet, but it may not always be the best option. However, if you decide to fit an elongated seat on a round toilet, follow the tips outlined above to ensure the best fit for your bathroom.

With the proper installation, you can enjoy a comfortable and convenient toilet experience feeling confident that your new toilet seat will stay firmly in place.
