Who makes the tallest toilet on the market? (Top models)

The toilet is an important part of every home, but finding one that fits your height isn’t always easy. There are many types of toilets available, yet most have similar seat heights. If you’re over six feet tall, a standard toilet may feel too low, especially when sitting down or standing up.

That’s where the tallest toilets come in. These extra-tall models offer a higher seating position that may be more comfortable for tall adults, seniors, and people who have difficulty bending their knees.

A standard toilet typically has a bowl height of around 14–16 inches, while comfort-height models usually offer a seat height of approximately 17–19 inches. Some extra-tall toilets go beyond that, reaching around 20–22 inches with the seat installed.

However, taller doesn’t automatically mean better. The right height depends on your leg length, mobility, and personal comfort. Let’s look at the tallest toilets available, the brands that make them, and how to choose the right one.

How Tall Are the Tallest Toilets?

Most extra-tall floor-mounted toilets have bowl heights around 19–21 inches. When the toilet seat is installed, the sitting height can be another inch or more.

Some wall-hung toilets allow adjustable installation heights, although the final height depends on the carrier system and manufacturer’s instructions.

Here’s a general comparison of toilet heights:

Toilet Type	Typical Height	Best Considered For
Standard toilet	14–16 inches to bowl rim	Average-height or shorter adults
Comfort-height toilet	17–19 inches to seat top	Adults wanting a higher sitting position
Extra-tall toilet	19–21 inches to bowl rim	Taller adults who find standard toilets too low
Adjustable wall-hung toilet	Depends on installation	Bathrooms needing a customized seating height
Children’s toilet	Varies by age and fixture design	Young children

Important: Some manufacturers advertise bowl height, while others list the height to the top of the seat. Always check which measurement is being used before comparing toilets.

Why Do You Need a Tall Toilet?

Not everyone feels comfortable using a toilet with a standard seating height.

For taller people, sitting on a low toilet can require deeper knee and hip bending. Standing up may also take more effort.

A higher toilet may make these movements easier, particularly for someone with limited knee or hip mobility.

Here are some reasons to consider a tall toilet:

• More comfortable seating: A higher position may feel more natural for people with longer legs.
• Easier sitting and standing: Less knee and hip bending may help some users.
• Better fit for tall adults: Extra-tall models provide options beyond traditional comfort-height toilets.
• Useful for certain mobility needs: Some people with joint stiffness may prefer a higher seat.
• Different design choices: Extra-tall toilets are available in traditional and modern styles.

However, a toilet that’s too high can also be uncomfortable. If your feet don’t rest firmly on the floor, you may feel unstable while sitting.

For someone who uses a wheelchair or has significant mobility limitations, toilet height should be selected with professional guidance. A very tall toilet may make transfers more difficult rather than easier.

Who Makes the Tallest Toilets?

Several manufacturers offer toilets with higher-than-average bowls. Some specialize in extra-tall designs, while others include taller models within their regular product collections.

Below are three brands worth considering.

1. Convenient Height Extra Tall Toilet

Convenient Height is one of the best-known manufacturers of extra-tall toilets. The company focuses on providing a higher sitting position for people who find conventional toilets uncomfortable.

Its Model S toilet has a bowl rim height of approximately 20¾ inches and a seat height of around 21¾ inches.

That’s considerably taller than most standard toilets.

The higher seating position may be especially useful for taller adults who want to reduce how far they need to lower themselves when sitting.

The Model S also features an elongated bowl and a dual-flush system.

Key Features

• Bowl rim height: Approximately 20¾ inches.
• Seat height: Approximately 21¾ inches.
• Dual flush: 1.28 GPF full flush and 0.9 GPF reduced flush.
• Bowl shape: Elongated for additional seating room.
• Rough-in: Standard 12-inch installation.
• Included accessories: Slow-close seat, flush hardware, and mounting components.

The dual-flush system lets you select a lower water volume for suitable flushes, potentially reducing water consumption compared with using a full flush every time.

One thing to remember is that this extra-tall toilet is above the standard ADA-accessible seat-height range. It may suit a tall homeowner, but it isn’t automatically suitable for someone who requires an ADA-compliant bathroom.

2. Kohler Tall Toilets

Kohler is a well-established bathroom fixture manufacturer offering toilets in several designs and heights.

Although many Kohler toilets fall into the standard or comfort-height categories, the company also manufactures taller models.

One model worth considering is the Kohler Highline Tall K-25224.

Kohler Highline Tall K-25224

This two-piece toilet features an elongated bowl with a rim height of approximately 19 inches.

With a compatible toilet seat installed, the sitting height will be higher than the bowl rim measurement.

Its main features include:

• 19-inch bowl rim height.
• Elongated bowl for additional comfort.
• 1.28 gallons per flush.
• Kohler Class Five flushing technology.
• Standard 12-inch rough-in.
• Two-piece construction.

The toilet seat and supply line are sold separately, so you’ll need to include those items when calculating the installation cost.

Kohler also offers other Highline and Comfort Height models, but their dimensions vary. Don’t assume every Highline toilet has the same seating height.

3. Signature Hardware Tall Toilets

Signature Hardware is another bathroom fixture brand worth checking when shopping for taller toilets.

The company offers a variety of traditional and contemporary toilet designs, including some models with unusually high bowls.

The Bradenton Elongated Two-Piece Toilet is a notable example.

Bradenton Elongated Two-Piece Toilet

Signature Hardware lists a Bradenton configuration with a 21-inch nominal bowl height, making it one of the taller conventional floor-mounted toilet options.

This model is worth considering if you want an extra-high seating position without using a separate toilet seat riser.

Important considerations include:

• Extra-tall elongated bowl design.
• Two-piece toilet construction.
• Traditional styling suitable for many bathrooms.
• Higher sitting position than most comfort-height models.
• Seat height depends on the toilet seat selected.

Signature Hardware also sells other toilets under the Bradenton name, so check the exact bowl-height specification before ordering.

Some older model listings and configurations may differ from current products. Always confirm dimensions, included accessories, and availability with the manufacturer.

Which Tallest Toilet Is Best for You?

The best option depends on how high you want the seat and how comfortably you can use it.

Toilet Model	Bowl Height	Main Advantage
Convenient Height Model S	20¾ inches	High seat with water-saving dual flush
Kohler Highline Tall K-25224	19 inches	Established brand with Class Five flushing
Signature Hardware Bradenton Extra Tall	Approximately 21 inches	Very high bowl with traditional styling

For someone who needs a higher sitting position, Convenient Height and the extra-tall Bradenton are worth comparing.

If you prefer a slightly lower bowl, the Kohler Highline Tall may offer a better balance between height and everyday comfort.

But remember that a one-inch difference can noticeably change how a toilet feels, particularly if your feet barely reach the floor.

How to Choose the Right Tall Toilet Height

Before buying one of the tallest toilets, take a few minutes to check your actual seating needs.

1. Measure Your Comfortable Sitting Height

Sit on a stable chair where your feet rest flat on the floor.

Notice whether your knees and hips feel comfortable and whether you can stand without excessive effort.

Measure the chair’s seat height from the floor. This can provide a useful starting point for choosing a toilet, although toilet shape and seating position will feel different.

2. Check the Height With the Seat Installed

A manufacturer may advertise a 20-inch toilet, but that measurement could refer to the ceramic bowl rather than the finished seat height.

The seat may add approximately an inch or more, depending on its design.

Always compare the height you will actually sit on.

3. Consider the Bowl Shape

Elongated bowls generally offer more seating room than round bowls. However, they also take up more space in front of the toilet.

If your bathroom is compact, check the overall dimensions before purchasing.

4. Measure the Rough-In Distance

The rough-in is the distance between the finished wall behind the toilet and the center of the floor drain connection.

A 12-inch rough-in is common, but some bathrooms use 10-inch or 14-inch arrangements.

Even the tallest toilet won’t fit properly if the rough-in doesn’t match your bathroom.

5. Think About Mobility and Balance

A higher toilet may reduce bending, but it can also make it harder for shorter household members to place their feet flat on the floor.

If multiple people share the bathroom, choose a height that works safely for everyone.

For accessibility-related installations, consult the applicable guidelines and consider professional advice.

Are the Tallest Toilets ADA-Compliant?

Not necessarily. This is an important distinction that many buyers overlook.

Under the U.S. ADA Standards for Accessible Design, the typical required toilet seat height is 17–19 inches above the finished floor, measured to the top of the seat.

An extra-tall toilet with a 21-inch or 22-inch seat height generally exceeds that range.

That doesn’t mean you cannot install one in your private home. It simply means the extra height should not be confused with ADA compliance.

ADA requirements also involve the toilet’s placement, surrounding clearance, grab bars, and other accessibility features.

You can review the official U.S. Access Board toilet accessibility requirements for more information.

Are Extra Tall Toilets Comfortable for Short People?

Usually, an extra-tall toilet isn’t the best choice for a shorter adult.

If your feet don’t rest comfortably on the floor, using the toilet may feel awkward and make it harder to maintain a stable sitting position.

A higher seating position may also be uncomfortable for people who prefer a deeper squat-like posture during bowel movements.

For a bathroom shared by people of different heights, a comfort-height toilet may be a better compromise than an extremely tall model.

It’s always better to test a similar seat height before making a final decision.

Frequently Asked Questions

1. What is the tallest toilet you can buy?

Some conventional floor-mounted toilets have bowl heights around 21 inches, with the installed seat making them taller. Convenient Height and Signature Hardware offer examples. Availability and exact dimensions vary by model.

2. Is a 20-inch toilet good for tall people?

A 20-inch bowl may be comfortable for some tall adults, particularly those with longer legs. However, the final seat height and your ability to place your feet firmly on the floor matter more than overall body height alone.

3. Does Kohler make a 20-inch tall toilet?

Kohler’s Highline Tall K-25224 has a 19-inch bowl rim height. The finished sitting height depends on the seat installed. Check the model’s specification sheet rather than relying on the advertised height alone.

4. Are 21-inch toilets ADA-compliant?

A toilet with a 21-inch seat height generally exceeds the ADA’s standard 17–19-inch seat-height requirement. Accessibility compliance depends on the complete installation and applicable standards.

5. Is an extra-tall toilet better for seniors?

It may help some seniors who have difficulty bending their knees or standing from a lower position. However, a toilet that’s too high can make sitting, balance, or wheelchair transfers more difficult.

6. Can I make my existing toilet taller?

Yes. Some raised toilet seats and toilet seat risers can increase the sitting height without replacing the entire toilet. Choose a compatible, securely installed product and confirm that it meets the user’s safety and mobility needs.

Conclusion

Finding the tallest toilets isn’t as difficult as it used to be. Brands such as Convenient Height, Kohler, and Signature Hardware offer higher toilet bowls for homeowners who need more height than a conventional model provides.

The Convenient Height Model S is worth considering if you want an extra-tall toilet with dual-flush functionality. Kohler Highline Tall provides a slightly lower option, while Signature Hardware offers an especially tall Bradenton configuration.

However, choosing the tallest toilet isn’t always the smartest decision. The best toilet is the one that lets you sit comfortably, keep your feet supported, and stand up safely.

Measure your preferred sitting height, check the manufacturer specifications, and make sure the toilet fits your bathroom before buying.
