Below I have discussed more about the 21 inch bowl height and Signature Hardware Bradenton  and the 21 inch seat height 20″ Extra Tall Toilet. These two are the tallest seat height toilets you can buy now.

21 Inch Bowl Height Toilet

If you are looking for a 21 inch bowl height toilet to purchase there’s is no exact 21″ bowl height toilet at the moment but theirs one with nearly a 21 inch bowl height.  It is the 20-1/2 inch bowl height Signature Hardware 945956 Bradenton 1.28 GPF Two-Piece Elongated Toilet (Check at Amazon #ad).

With a nearly 21 inch high toilet bowl, this is the tallest toilet for sale in the American market today. It comes with a standard seat included which give it a seat height over 21 inches. You can check its specification sheet here for exact dimensions and size diagram).

As for the overall size of the toilet, this Bradenton toilet measures 29 inches long, 17 inches wide and 34 inches tall. The 29″ length is within the normal 28″-30″ standard toilet length range of modern toilets. Width is also only 17″ wide, which is also within the standard toilet width range. So even though it has over 21″ tall seat level, its length and width is the same as a normal standard elongated bowl two-piece toilet.

The tall bowl and therefore the tank positioned at a higher level, that make this toilets overall height 34″ tall. Even that 34″ overall height falls within the range of many high profile toilets with tall toilet tanks available in the market. So proportion and dimension wise I think they have done a good job to make this toilet fit in the same toilet space of a normal bathroom. It’s also got the same 12 inch rough-in (wall to drain hole length) size as normal toilets.

20″ Extra tall toilet is also a water saving low flow toilet. Its flush water consumption is just 1.28 Gallons per Flush (1.28 GPF).  I read that the high efficiency flush works well to move things through and out of the bowl. So it can be installed in states like California were regulations require 1.28 GPF toilets.

This 21″ Signature Hardware Bradenton toilet was released very recently, only in April 2020, during the beginning of the Covid-19 outbreak. Yet judging by the number of online reviews and ratings its got so far, it seems to be selling a lot. The online reviews and ratings I checked were also very positive about this toilet.

As for the Signature Hardware toilet brand, I’ve had previous experience with their toilets and I can recommend them. Signature Hardware toilets are as they describe and you get what they say. They are a old and very reputable bath and kitchen items supplier based in Northern Kentucky.

One concern with such a high seat toilet is weather it will be difficult for short people. While researching for this post, I read that customers as short as 5′ 3″ have had no issues using this toilet. However I think if someone shorter than 5′ 3″ is going to use this toilet, they may have some trouble getting off/on. For a 5′ foot person it may be more of a hop up and slide off. If the toilet is regularly used by a 5′ 2″ or shorter person they can maybe try using a toilet stool (check at Amazon #ad). Or maybe get one of the shorter, 19″ and 18″ bowl height toilet as a happy medium.

20 Inch Bowl Height Toilet with 21 Inch Seat Height

If the 21″ Bradenton toilet is too high or you want to see an alternative, your next best option is 1-inch shorter. It’s the 20 Inch Extra Tall Toilet from Convenient Height Co. (Check at Amazon #ad). Lets have look at it here.

This 20″ Extra Tall Toilet is the second tallest toilet you can get in the market today. It has a 20 inch toilet bowl height and 21 inch toilet seat height.  It also comes with a slow-closing toilet seat included. (Here’s the link to its specification sheet.)

Overall dimension and size wise the 20″ Extra Tall toilet measures similar to the Bradenton toilet. The 20″ Extra Tall Toilet is 27 inches long, 15 inches wide and 36″ inches tall. So length and width wise it takes the same space as a normal toilet would  and fits a standard 12-inch rough-in drain hole.

20″ Extra tall toilet is also a water saving dual flush toilet, meaning you have the option to use the normal full flush button at 1.6 Gallons per flush for flushing solid waste and the water saving flush 0.9 gal/light.

Here is a video about the Convenient Height 20 inch Extra Tall Toilet and how it helps sitting down and getting up easier.

This 20″ Extra Tall toilet was first released in 2016 by a new toilet maker called the Convenient Height Co. located in Massachusetts. It was first available for sale on Amazon around July 2018. It has since sold thousands or probably even tens of thousands units. You can judge how good and popular it is by the hundreds of reviews its got on its online sales pages.

This 20 inch Extra Tall Toilet was the first mass produced toilet in the American market that was taller than the 17″-19″ ADA Comfort Height range. That’s why the Convenient Height Co. calls themselves as the, “makers of the world’s first original tall toilet!”

Few years ago when this 20″ Extra Tall toilet was first sold, there weren’t even any widely available 18 or 19 inch bowl height toilet for sale. At that time, if someone asked for a 19″ to 21″ tall toilet, toilet dealers use to say that you’ll never find a tall toilet over 16-17 inches unless it’s custom built limited edition one with a price tag over $1,000!  So there was lot of pent up demand for taller toilets like this.

When the 20″ Extra Tall Toilet was launched it caused a big bang in the toilet industry and sold like hot cakes. All the other 18 to 21 inch tall toilet models listed here were produced after seeing the demand and success of this 20″ Extra Tall Convenient Height Toilet.

20 Inch Toilets

20 inch toiletIf you would like a 20 inch toilet there are two models. One is the 20 inch bowl height Extra Tall toilet we discussed above which has a 21 inch seat height. The other is the new Kohler K-25224-0 Highline Tall Toilet (Check at Amazon #ad).

This Kohler Highline Tall features a 19 inch toilet bowl height and a 20 inch toilet seat height. Overall it gives you a 2/3 inches taller seat height than the average 17-inch high comfort height toilets for sale in the market.

This Kohler Highline Tall toilet was release around November 2019. That means its available in the market even before the 21″ Signature Hardware Bradenton toilet. However when I checked online reviews and forums there isn’t much news about this toilet. I guess with more taller toilets available it hasn’t got much attention as it deserves. Kohler has also not done much marketing about this toilet yet.

However 20 inch seat height is a very ideal height for a 6 foot tall person. With average American male height being 5′ 11″ I’m surprised there aren’t more sales of this 20 inch tall toilet. Specially since its from Kohler, one of the top 3 American toilet brands along with American Standard and TOTO.

19 Inch Toilets

19 inch toilet A 19 inch seat height toilet is the most comfortable toilet seat height for someone with a height of around 5′ 11″ tall. So far I’ve only found one 19 inch seat height toilet, namely the Signature Hardware 413995 Stalnaker Toilet (Check at Amazon #ad). I

I’ve included this 19″ Stalnaker in the above comparison chart with its key features for easy comparison with the other 20 & 21 inch toilets. If you are interested for more details you can check my 19 inch high toilet post here.

18 Inch Toilets

18 inch seat height toilets are better for household or bathrooms where the toilet will be used by a mix of tall and medium height people. It maybe short for over 6 feet tall individuals but a compromise is needed if the toilet is shared with short height family member or friend.

The only 18 inch seat height toilet I’ve come across so far is the Kohler K-3493-0 Highline Classic Pressure Lite Toilet (Check at Amazon #ad). This toilet is also included in the above comparison chart where you can checkout more details about it. I’ve looked into it in detail in my 18 inch high toilet post here.

Note: There are several toilet models with the name of Kohler Highline in the market. Only the Kohler Highline toilet with the model number K-3493-0 has a 18 inch high seat height. Other models have the same design but vary in seat height and features like water consumption rate etc.

Time To Choose!

That brings us to the end of my post about the best 21 inch tall toilets. I hope I have given you what you need to make the best choice for you.

Overall I think both the 21″ Signature Hardware Bradenton Toilet (Check at Amazon #ad) and 20″ Extra Tall Toilet (Check at Amazon #Ad) are good choices. The 20″ Extra tall toilet is little pricey and bit shorter, but still has been in the market longer and has got thousands of satisfied customers. Both look good, have a similar overall dimension, save water and flush well.

Whichever height toilet you choose, I hope I’ve demonstrated good details to help you in get a good tall toilet.
