What is the Highest Toilet Available

What Is the Highest Toilet Height Available? (With Examples)

Using a toilet shouldn’t ever be an uncomfortable experience. However, if you’re elderly, disabled, or very tall, getting up after using the toilet can be uncomfortable and sometimes even painful. If you’re investing in a new toilet, what is the highest toilet height available? 

The highest toilet height available is 21 inches (53 cm) tall without any modifications. However, after modifying it or using risers, you can adjust your toilet to be 28 inches (71 cm) tall. 

In this article, I’ll discuss the highest toilet possible height. I’ll also provide a few examples of tall toilets on the market and discuss the pros and cons of these types. Let’s get to it! 

What’s the Highest Possible Toilet Height?

The highest possible toilet height is 28 inches (71 cm) tall. This is the height after modifications and refers to a custom-built toilet. The highest a toilet can be without adjustments and modifications is 21 inches (53 cm) tall. Most standard toilets are 14-15 inches (36-38 cm) tall.   

If you’re in the market for a new and higher toilet, you should be aware of 2 important toilet terms: 

  • Standard height. These toilets are typically 14-15 inches (36-38 cm) high, and you’re most likely to find them in normal households, apartments, and public spaces. However, they are not the most comfortable height for many members of the population, especially really tall people, the elderly, and people with disabilities.  
  • Comfort or chair height. These toilets are slightly taller than regular ones, with heights of 17-21 inches (43-53 cm). They comply with the Americans with Disabilities Act recommendations, making getting up less complicated or painful for people with disabilities and the elderly because there is less distance to travel to the toilet seat.

These toilet descriptions provide consumers with key information about the toilet’s height.

The heights listed above are the toilet heights without any additional modifications or changes to further increase the height. If 21 inches (53 cm) isn’t tall enough for you, there are things you can do to add some extra inches. Here are some ideas: 

Add a Seat Riser

A sear riser is extra material that is located underneath your toilet seat. You can normally attach a seat riser to your toilet seat with bolts. If you live in a household with people who don’t need a seat riser, you can buy a model that allows you to move it out of the way when you use the toilet. 

Since seat risers are adjustable, they are ideal for those living in a shared household. 

If you’re looking for a high-quality yet affordable seat riser, consider the HealthSmart Raised Toilet Seat Riser from Amazon.com. This model adds 5 inches (12.7 cm) of height to your toilet and is also a universal model, so is sure to fit your toilet. 

When buying a seat riser, look for one that comes with slip-resistance pads (like the model above). These firmly adhere to your toilet bowl for stability, and you won’t have to worry about the riser shifting around when you use it. 

Use an Elevated Toilet Seat

Elevated toilet seats replace your original toilet seat completely, making it different from a 

seat riser. Seat risers sit on top of the original seat but don’t replace it. Most elevated toilet seats attach to the toilet with a clamping mechanism. 

If you’re trying to add height to your toilet to help an elderly person or a person with disabilities, I recommend the RMS Raised Toilet Seat from Amazon. This model adds another 5 inches (12.7 cm) of height to your toilet and also has padded foam arms to make it easier for people to sit or stand and use the toilet. The arms are adjustable, so you can make them as wide or narrow as you’d like, and the installation is tool-free and simple.  

Install a Wall-Hung Toilet

If you are very tall, a seat riser or elevated toilet seat might not give you the height you need in your toilet. In such cases, you should consider a wall-hung toilet, which can add another 28 inches (71 cm) in height. 

Wall-hung toilets are extremely expensive but usually have an insulated tank that prevents sweating, an actuator plate opening, and dual-flush technology. Hence, you get additional features for the price you pay. 

The best wall-hang system is the Kohler Veil-in-Wall Tank and Carrier System from Amazon.com. This system features a robust steel tube frame that is as aesthetically pleasing as it is durable, and it comes with dual-flush technology that allows you to choose between a full or partial flush. This feature helps save water, reducing your water bill and environmental impact.   

With these modifications, the tallest toilet you could achieve is around 28 inches (71 cm) tall. If you want a toilet even taller than that, you’ll need to look into getting a custom build, which can be a very costly endeavor. Additionally, you’ll have to consider how much space a tall toilet would take up and if it’s possible to build in your space.   

Examples of Tall Toilets 

Toilet manufacturers have taken note of the need for taller toilets, especially for people who have difficulties sitting or standing. If you’re very tall, elderly, or have disabilities, you would benefit from a taller toilet. 

The Americans with Disabilities Act states that the optimal toilet height for those with disabilities is between 17 and 19 inches (43 and 48 cm) tall.

However, if you require an even taller toilet, you still have options. Here are some examples of tall toilets that may suit your needs. All links are to Amazon: 

Signature Hardware Store Bradenton Two-Piece Elongated Toilet

This is probably the highest toilet on the market. It’s 22 inches (55.8 cm) from the floor to the top of the bowl and has a larger toilet bowl to make using the toilet a more comfortable experience. 

The gloss-enameled porcelain and the simple design work with nearly all bathroom styles, so you don’t have to worry about the toilet sticking out or being too distracting in your existing bathroom design. 

Other features include a visible trapway and a soft-close mechanism that prevents you from slamming the toilet seat down and causing damage. 

Convenient Height Store 20 Inch Extra Tall Toilet

This is another tall toilet to consider. It measures 20 inches (51 cm) high and offers many fantastic features. 

The baseboard heater fit is built with bowl back-end structural reinforcement, so the baseboard heaters can fit behind the unit. 

Another great feature is the durable flush actuator, which connects with the metal handle with a durable connection engineered to last through many years and uses. The flush is exceptional, too, thanks to the added height, because the trap-way uses the height for an extra powerful, gravity-based flush.

Finally, the slow-closing seat is well-fitted and prevents damage due to closing too quickly. Overall, this toilet is a great example of a high, comfort-size toilet, and it’s easy to see why it is one of the most popular comfort toilets on the market.  

Kohler Highline Toilet

The Kohler toilet has a clean and simple design that works with almost every bathroom design, and you can choose between a round bowl and an elongated bowl. I like the elongated bowl because it adds additional space and comfort for those who need it. 

The toilet is only 2 inches taller than most standard toilets, so it isn’t as tall as other options. However, the extra 2 inches may be all you need. At 19 inches (48 cm) tall, it is also ADA-compliant if that’s a feature you’re prioritizing in your toilet search. 

The toilet comes equipped with Class Five flushing technology, in which gravity creates a strong siphon after the flush, which results in a powerful rinse that leaves a clean bowl almost every time. On top of that, the toilet conserves water because it only uses 1.28 gallons (4.85 liters) per flush. This lower water consumption results in nearly 16,500 gallons of water (62,459 liters) saved per year compared to a standard toilet. 

WinZo Elongated Two Piece Toilet With Extra Tall Bowl 

This toilet is 21 inches (53 cm) from the floor to the lid, which is plenty of extra height for most people. It has a high-performance gravity and uses 1.28 gallons (4.85 liters) per flush, which conserves water and keeps the toilet bowl clean. The toilet comes with a factory flush, which ensures optimal performance for as long as possible.  

I also like that this toilet has a standard elongated toilet bowl because the standard size makes it easier to get a replacement if need be. Many local stores and home improvement chains have plenty of options for replacement toilet seats in standard sizes.  

Finally, the two-piece configuration allows for more access to areas around the toilet, which is great for people with limited bathroom space. The access to areas around the toilet makes up for the additional space the tall toilet takes up.  

Pros and Cons of Tall Toilets

Before you invest in a new tall toilet for your home, you must understand the advantages and disadvantages of having this kind of toilet. 

Pros of Tall Toilets

Let’s take a look at the benefits first:  

  • Tall toilets are more convenient for people with limited mobility. If someone in your household has limited mobility, using the toilet can go from a simple, everyday task to a painful ordeal. Installing a tall toilet allows them to move less while going to the bathroom, which means less pain in their day. 
  • Tall toilets are helpful for tall people. Extremely tall people have some struggles they have to deal with throughout the day: hitting their head on the ceiling, not fitting into public transportation, etc. Installing a tall toilet results in less inconvenience and discomfort they have to deal with because of their height. 
  • They make it easier to sit down and get up again. Some shorter toilets require a lot of work to get up from, and a tall toilet eliminates that extra energy expenditure. Some elderly people don’t have pain or joint problems, but they have a limited amount of energy every day, so these toilets are more comfortable because they involve less work and movement.  
  • Taller toilets are ADA-compliant. Suppose you’re considering a tall toilet for your house, a public building, or a business. In this case. you should be inclusive in your building design, and comfort toilets are ADA-compliant. Most standard toilets are not. 

Cons of Tall Toilets

Now that you understand the good things about tall toilets, it’s important to consider the disadvantages. 

Here’s what you should know:  

  • Kids can’t use tall toilets. Very young children might already struggle with standard-size toilets, let alone tall toilets. Having a tall toilet in the home means fewer toilets that the kids in your house can use. If you live in a house with children, a tall toilet may not be the best option. 
  • Tall toilets aren’t suitable for short adults. Children aren’t the only ones who struggle with being too short for the world sometimes! Short adults can also struggle to use a tall toilet. One solution is to get a stepstool that they can put their feet on while sitting on the toilet and climb up, but this can be a hassle and may take up too much space in the bathroom.  
  • Users can lose circulation in their feet. If someone’s feet dangle from the edge of the toilet instead of resting flat on the ground, they can lose circulation and feeling in their feet. This is more likely to happen if they spend a lot of time on the toilet. The condition is uncomfortable and potentially harmful. 
  • Tall toilet users are more likely to experience constipation. When passing a bowel movement, it’s best to squat because this helps the pelvic floor muscles relax and pass the stool easily. If someone sits on a tall toilet, the pelvic muscles can’t relax properly, and it becomes more difficult, even impossible, to release the stool.   
  • Most comfort toilets are more expensive than standard toilets. Comfort toilets aren’t as widely available as regular models, and they are usually more expensive. A comfort toilet may be out of your budget. However, there are many options at various price points, so it’s important to shop around before deciding that a tall toilet is too expensive.  
  • You might not have space. Since they are larger than their regular counterparts, tall toilets take up more space. If your bathroom is particularly small, a tall toilet might not fit properly. 

You must consider all aspects of the tall toilet before purchasing and installing one in your home. You should also consider all the members of the household, as the right toilet height for one person may be completely different than the right toilet height for someone else.   

What Toilet Height Is Right for You? 

Before investing in a new toilet, it’s worth determining the most suitable height for you and your loved ones. Here’s what you should consider: 

  • Are you sharing the toilet with anyone? If you’re seven feet tall, you’re probably confident that a tall toilet is right for you. However, if you live with someone only five feet tall, that toilet wouldn’t be very comfortable or usable for them. Before you purchase a tall toilet, take a moment and consider everyone who needs to use the toilet regularly. 
  • Do you have a disability that makes standing up or sitting down painful? If sitting down on a toilet and standing up again is painful or uncomfortable, a taller toilet may make going to the bathroom less of an ordeal for you. 
  • If you sit on the toilet, your feet should be flat on the ground. Having your feet dangle while sitting on a toilet is uncomfortable and can cause you to lose feeling in your legs or toes. 
  • Should you use a seat riser instead? Toilet seat risers often feature hinges that allow you to swivel the riser in and out of place. Using a seat riser is an excellent option if both tall and short people will use the toilet. 
  • Do you have bowel problems? If you have a bowel condition or often suffer from constipation, a toilet that allows you to put your knows above your hips can be beneficial. This position allows for more pelvic floor relaxation, which is ideal for overcoming constipation. 

If the last question applies to you, you might consider addressing the issue with a Squatty Potty. The Squatty Potty is a stepstool that puts your knees above your hips, so you’re in a more squat-like position. This moves your colon into a better position to release stool without straining. 

I recommend the Squatty Potty Oslo Folding Bamboo Toilet Stool from Amazon because it is foldable, and you can store it more discreetly and easily. I also like the non-slip mats and grooves on the stool that allow you to securely hold your feet in place. Finally, the bamboo material makes the stool appear classier than plastic.    

After considering these factors, you should be able to determine whether or not a tall toilet is right for you or whether another tool, like a seat riser or a Squatty Potty, is better for your household.   


The tallest toilet you can get without modifications or additions is 21 inches tall. However, adding a seat riser or an elevated seat can add extra height, up to around 28 inches. Installing a tall toilet makes using the toilet more comfortable for the elderly, tall people, or those with disabilities.
