If you were to buy a pressure-assisted toilet without any preparation, there is a significant chance that you would be disappointed with the purchase. After all, you would be relying on luck rather than your wit to help you select the best pressure-assisted toilet.

At the least, you should be on the lookout for specified features in the toilets you consider bringing home. The bowl shape and height should be looked at for comfort reasons. Second, you can take note of the type of toilet as well as dimensions as these will determine installation. Once you have ticked those boxes, you can go further to evaluate user experience. This can be seen in whether the toilet is single or dual flush, as well as the water efficiency you get with the product. Remember, materials used in making the toilet also affect the use of the toilet and how long it lasts. In conclusion, most high-quality toilets also feature excellent warranty terms in their purchase. These features form the criteria that bring you the list of seven best pressure-assisted toilets presented below.

Top 7 Pressure-Assisted Toilets Review 2021


American Standard 2467016.020 CadetEditor’s Choice

  • Type: two-piece
  • Shape: elongated
  • Bowl height: 16.5 inches
  • Flush: single, 1.6 GPF
  • Dimensions: 30.25 x 20.5 x 30.75 inches
  • Material: Vitreous China
  • Warranty: 1-year limited

Other features: fully glazed 2-1/8 inch trapway, close-coupled Flushometer tank, 12″ rough-in

The American Standard 2467016.020 Cadet is the first pressure-assisted toilet to feature on our list. It is also the editor’s choice meaning that it ranked the highest out of all the options we reviewed in the making of this list.

Despite the picture of the toilet we have provided above showing all significant accessories, the toilet seat is left out of the initial purchase. This takes away some points from the product’s rating. However, the toilet still has enough positive features to be deserving of its place on this list.

If you are familiar with different toilet construction materials, you will be impressed that vitreous china is used in the making the American Standard 2467016.020 Cadet. An attribute that you can already attribute to the toilet as a result of the construction is that it is not easily damaged or scratched.

Additionally, vitreous china toilets are incredibly resistant to staining. Nonetheless, it is still an excellent idea to clean the toilet regularly.

Also important is the size of the trapway. Remember that this component takes away all your waste to the sewage or the septic tank attached to your toilet. If you buy a toilet with a small trapway, then you are setting yourself up for lots of clogs. Nonetheless, the size available in this particular toilet is sufficient.

Additionally, this is an elongated toilet, which means it is built for comfort. However, that can come at the cost of taking up more of your bathroom space. If you are comfortable with that, go right ahead and make the purchase.

You as well have to remember that a lot of chairs offer seats that are around the 17-inch mark when it comes to height. Most people are comfortable with that, and hence a 0.5-inch reduction will still allow them to be comfortable while on the toilet.

Lastly, this is a single-flush toilet that releases 1.6 gallons of water per flush.

What stands out?

  • Durable and stain-resistant construction
  • Comfortable bowl design and height
  • 1-year warranty
  • Relatively easy to clean

What cons did we manage to find?

  • No toilet seat
  • Noisy flushing

Kohler K-3493-0Premium Choice

  • Type: two-piece
  • Shape: elongated
  • Bowl height: 17 1/4 inches
  • Flush: single, 1.6 GPF
  • Dimensions: 30 1/8 x 21 1/4 x 31 1/4 inches
  • Material: Vitreous China
  • Warranty: 1-year limited

Other features: 12-inch rough-in, 2 1/4-inch trapway, left-hand trip lever flush handle, Pressure Lite flushing system

For taller individuals, you might have to look into taller bowls, especially if comfort is important to you. This is where the Kohler K-3493-0 Highline comes in since the bowl is placed 17¼ inches off the floor.

Similar to the American Standard 2467016.020 Cadet, this toilet comes in a two-piece design. This means that you will be provided the toilet bowl and the cistern as separate devices. It will thus be your job to put these two together when you do the installation. You can find a plumber in your home area to do the installation for you at a fee if it proves too difficult.

Also, it one-ups the predecessor with regard to the size of the trapway by an eighth of an inch. This means more clearance for your waste to go through. Some users as well are not fans of white toilets. This is an understandable preference and one which the manufacturer caters to. You thus have almond and biscuit finishes in addition to the white one.

Be advised that both the almond and biscuit color toilets come at a higher cost. Also, this is another elongated toilet. It still occupies a lot of bathroom space, but it might be worth it for a lot of you. Additionally, don’t forget about the rough-in. You may need to take some measurements in your bathroom just to ensure that the toilet is compatible.

Vitreous china is also a prominent feature in the making of this toilet. When you are done with relieving yourself, you should find a flush handle on the left side of the tank. In line with the lever design, this is a single flush toilet. Nonetheless, it does seem that a single twist of the lever proves sufficient in most situations.

Again, this is yet another toilet option where you need to think of the toilet seat as a separate purchase.

What are its best features?

  • Durable construction
  • Comfortable bowl height and elongated design
  • Large trapway
  • A variety of toilet finishes are available

What could be improved?

  • The toilet seat isn’t included in the purchase
  • The product is expensive
  • Loud

Zurn Z5572Best Warranty

  • Type: two-piece
  • Shape: elongated
  • Bowl height: 15 3/8 inches
  • Flush: dual flush, 1.6/1.2 GPF
  • Dimensions: 30 3/8 x 19 x 9 ¾ inches
  • Material: Vitreous China
  • Warranty: 10-year

Other features: 12-inch rough-in, ultra-quiet flush, 2 1/8-inch fully glazed trapway

Some people would purchase the Zurn Z5572 just for the 10-year warranty it comes with. The only competition on this list that provides a guarantee that is on par with the Z5572 is the  Zurn Z5562.

The two-piece toilet makes the best use of its high-performance EcoFlush technology to make sure your waste goes to either the sewage or the septic tank. As to the bowl height, it may be a little shorter than what you get with other options. You can place it on a platform to account for this deficit if you want.

However, installing it as it is on the floor doesn’t go against any rules. Also, some of you may even be more comfortable this way. Nonetheless, this is still an elongated toilet, meaning it needs your bathroom to be relatively large if it is going to fit.

Also, remember that it conforms to the 12-in rough-in that is common in a lot of modern toilets. However, assuming that your rough-in is the same size without taking the time to measure, it may be a huge mistake.

It has been mentioned above that this is a dual flush toilet. After peeing, it is best to use less water to flush. In this case, it is 1.2 GPF. However, when you excrete solid waste, you want to use as much water as possible. This ensures everything goes down the trapway. In such a scenario, you engage the 1.6 GPF flush.

Furthermore, users have complained a lot about some of the top toilets being noisy. If you dislike noisy toilets, you can get this product since it guarantees noiseless flushing.

What makes it special?

  • Noiseless flushing
  • 10-year warranty
  • Dual-flush system helps save on water
  • Uses an elongated bowl design

What cons did we find?

  • At under 16 inches, the bowl height may be uncomfortable for some taller people to sit on

  • Shape: elongated

  • Flush: dual, 1/1.6 GPF
  • Dimensions: 32 x 19 x 20 ¾ inches
  • Material: Vitreous China
  • Warranty: 10-year

Other features: high-performance EcoFlush™ technology, easy touch handle actuation, 2-1/8” fully glazed trapway

The Zurn Z5562 seems to have taken on the negative aspects of the Zurn Z5572 and turned them into positives. This is especially the case where the bowl height is concerned. Being 17 inches high means more people can be comfortable sitting on this toilet.

It features an elongated shape, which coincidentally makes the sitting experience even more comfortable. Both the tank and the bowl are made of vitreous china.

Also, the 2-1/8” trapway seems like the ideal addition to the design of the toilet. Remember that it is fully glazed, just like the rest of the toilet. Consequently, it is highly unlikely that any of your waste will stick to the surface of the trapway.

Further ecoflush technology is a critical element of ensuring efficient flushing. This works in conjunction with the dual flush system to ensure you conserve as much water as possible. As such, you may be doing something small for the environment by purchasing this toilet.

In conclusion, you don’t have to struggle with the toilet after you are done relieving yourself owing to the easy-touch handle actuation feature.

Why are we impressed?

  • Easy-touch handle actuation
  • Dual-flush system
  • 10-year warranty
  • 17-inch bowl height

Other features: EverClean Surface, 10″ x 12″ water surface area, Speed Connect® tank/bowl coupling system

Children may prefer using a lower toilet bowl than other people in your family. For this reason, the American Standard 2462.016.020 Cadet might be the ideal purchase for households with lots of children.

For one, the vitreous china construction is considered top-notch. However, if we are going to be critical about the toilet, the two-piece design may be harder to clean. This is because there are spaces where the tank and bowl are attached that are impossible to reach.

Nonetheless, the speed connect coupling system does make the attachment of the two components quite easy. You as well have an EverClean bowl surface that you get with the purchase of this toilet. You will only be required to do a little bit of maintenance to keep the surface of the toilet pristine. The rest of the clean-up work will be done by the flushing system every time you relieve yourself.

Also, the amount of water used for flushing the toilet is the same since this is a single flush device.

What do we love it for?

  • Easy to put together
  • Standard 12” rough-in

If you come across the Kohler K-3505-0 Wellworth, it is certainly worth considering as a potential purchase. With its 12-inch rough-in, it will likely fit easily into most homes. However, you are always advised to make sure of this fact before making the purchase.

It also ranks high among other single flush toilets. However, it doesn’t have the water-saving capabilities of the American Standard 2876100.020 Yorkville mentioned below. This is because it uses 0.5 gallons of water more per flush.

The fact that it is elongated in design is also something to look forward to. With regard to the bowl height, you get 15.5 inches of clearance from the floor.

What makes it stand out?

  • Standard rough-in
  • 1-year limited warranty
  • Elongated bowl design

The American Standard 2876100.020 Yorkville helps you save water every time you go to the bathroom since it only uses up 1.1 GPF. You can as well see a lot of similarities between this product and the other American Standard options that came before it on the list. One example is the EverClean surface since it is also available in the American Standard 2462.016.020 Cadet.

The toilet comes pre-fitted with a 2 1/8-inch trapway that allows for the exit of all your waste. Also, it has a vitreous china body, which has been known to have some positive attributes.

Buyers getting this toilet also receive a 1-year warranty. That being said, it can face some of the problems faced by the American Standard 2462.016.020 Cadet. As you can see, both have a bowl that is 15 inches clear of the floor. Most children and small-bodied people may find this comfortable. However, taller people might not enjoy sitting on this bowl as much.

What do we love it for?

  • Durable, glazed construction
  • 1-year warranty
  • Uses very little water per flush
  • EPA Watersense labeled

What were we disappointed with?

  • The height of the toilet bowl makes it less enjoyable for tall people to sit on

Things to Consider

Deciding to purchase a pressure-assisted toilet is a big step. What follows is a more significant step where you determine which toilet to purchase. The many options available make it impossible not to get confused. However, the buying guide below will whittle away that confusion making the path you have to follow clearer.

What are pressure-assisted flush toilets?

7 Best Pressure-Assisted Toilets for More Powerful Flushing

Pressure assisted toilets allow for the best performance when flushing. This is because they incorporate two tanks in their design. One of these tanks is usually positioned inside the other. Also, the space in between these two tanks is often filled with air pressure. This pressure is then added to gravity while flushing to allow for more power. As such, you rarely need to flush twice with this type of toilet.

Benefits of pressure-assisted flush toilets

As mentioned, more flushing power is generated when using these toilets. This makes the toilet quite efficient. If you purchase such a tool, you will be saying bye to flushing your toilet two or three times.

Second, on the benefits list is the water-saving aspect. Most people also don’t pay attention to the water they use per flush. This problem is exacerbated by needing to flush multiple times. The result is that you waste a lot of water. This is water that you can save by purchasing a pressure-assisted toilet that only requires one flush. Remember that you will be doing a lot of good for the environment by being economical with your water use.

Pressure-assisted toilets also seem to have less moving parts. The result of this is that they don’t break down often. This also translates to requiring less maintenance.

Features to consider when choosing a pressure-assisted toilet

To the educated eye, it becomes quite easy to pick the best pressure-assisted toilet in the market. They can find the product that would fit their home and needs by going through the listed features. Since we aim to allow you to choose the toilet for yourself, we have provided a list of said features. Also, we have provided clarification on what they mean, so your eyes can be just as educated, allowing you to choose the product to purchase with relative ease.


On the list above, you should have noticed that we started the list of features by clarifying the type. However, the products that featured on the list were all the same type, which is a two-piece. This refers to the design of the pressure-assisted toilet.

Two-piece toilets come in two separate exterior components. The bowl is one and refers to the part of the product that you sit on. The second is the tank which stores water for flushing.

One-piece toilets are different in that they come as a single unit. They still have the tank and bowl components. Nonetheless, these are usually attached by the manufacturer. There are thus no spaces left between these two components.

Some two-piece toilets may experience leaks, especially if the installation is not done well. It could as well be because of damage to the connectors. However, with one-piece toilets, you will hardly ever see any leaks.

Although it wasn’t mentioned above, all the toilets featured are also floor-mounted. For this type of toilet, the differentiating factor is that they are installed on the floor of your bathroom. There is, however, a different type available, which is the wall-mounted toilet.

Wall-mounted toilets are attached to the wall and leave a bit of clearance between them and the floor. Also, once installed, you will not see the tank component since it is usually positioned behind the wall.

Lastly, you have corner toilets. However, these are quite rare because people don’t often plan on installing the toilet in the corner of their bathroom. Nevertheless, they are available. You can differentiate them from other types of toilets by looking at the cistern. If it has a triangular-shaped tank, then it is likely a corner toilet.

Bowl shape

Toilet bowls come in two main variations, which include round and elongated toilets. What was mainly used in the past is the round bowl option, and it makes up a lot of the toilets you would find in old buildings. However, elongated toilets are a more recent innovation. Benefits differ between these two.

The round toilets, for instance, are more compact. As such, if your bathroom space is tiny, round toilets will fit and still leave you some wriggle room. That being said, people have noted that these toilets are not very comfortable.

For comfort, the obvious choice is the elongated toilet. Just make sure to free up more space in your bathroom before you do the installation.

Single vs. dual flush

You may as well have to make that difficult decision of choosing between single and dual flush toilets. Single flush toilets like the American Standard 2467016.020 Cadet are quite common and popular. For these toilets, it doesn’t matter if you’ve relieved yourself of solid excrements or you were just peeing. The amount of water used to flush both of these waste options is the same. For the editor’s choice, it is 1.6 gallons per flush.

Dual flush toilets offer variations in the amount of water to be used for each flush. Pee generally requires less water to flush. As such, you have the option of using less water. This is seen in toilets like the Zurn Z5562 mentioned above. For solid waste, you are free to use all 1.6 gallons of water in the tank. For pee, you can opt to use 1.1 gallons instead, and that will save a lot of water in the long run.

Water efficiency

7 Best Pressure-Assisted Toilets for More Powerful Flushing

A product with the Watersense label has been deemed not to be wasteful in the use of water after testing. If you only buy toilets with Watersense certification, you are likely helping conserve a lot of water.


You cannot shop for a toilet without accounting for the size. After all, some toilets may not fit in your bathroom. As such, you should pay attention to all the dimensions. Once you have that data, you can pick a tape measure and get to measuring in your bathroom. Find out if your preferred toilet will fit in the space available or not.

Materials used

You have likely seen vitreous china again and again in the list above. It is one of the superior materials you can find in toilet construction. It is known to be scratch-resistant and stain-resistant as well.

There are also ceramic toilets. Some might say ceramic and vitreous china toilets are the same thing. However, the vitreous enamel coating in the vitreous china options makes up the difference. This extra layer of glaze is what adds to the stain-resistant and scratch-resistant features of the toilet.

Available color options

The Kohler K-3493-0 Highline is a popular pick despite being expensive due to the color options available. After all, not all people will be going for the traditional white toilet. Others may be going for a unique finish to complement the overall look of their bathroom.


Your bathroom will have mounting holes where you are likely to install your new toilet. If you measure the distance from the middle of these mounting holes to the wall, you will find out the rough-in. This should help you decide on the toilet to choose as different options have different rough-ins. Nevertheless, there are only three standard rough-in options. They are the 10-inch, 14-inch, and 12-inch rough-ins.

Noise level

With most pressure-assisted toilets, noise is to be expected. However, that can get annoying for some of you; hence you may be looking to avoid it. In such cases, you find toilets like the Zurn Z5572 that are readily available and barely produce any noise.

Water supply line

The toilets as well need a constant supply of water if they are going to keep flushing your waste away. They thus should be connected to the water pipes in your bathroom. However, you find that most of these cannot be linked directly due to their positioning. As such, a water supply line is needed to bridge the gap.

Some toilets come with a water supply line in the package, while others will need you to look at this accessory as a separate purchase. Make sure you know which of these packages you are subscribing to when you make your purchase.

Ease of installation

7 Best Pressure-Assisted Toilets for More Powerful Flushing

Plumbers are available to do the installation for you once you have the toilet delivered. However, you should always look for an easy-to-install product. That way, instead of hiring a plumber, you can do the installation and save your funds.


Toilet breakages can occur at any time requiring you to carry out some maintenance. Unfortunately, this may turn out to be a costly affair. However, the costs can be reduced by having a warranty. Of course, having a more extended guarantee means the manufacturer will cater for replacements and repairs for a longer time. Consequently, going for a toilet with an elongated warranty is probably best. Also, check whether it is a full or a limited warranty as that will dictate the kind of maintenance service you get once you make a claim.

Other features

Coming across extra features is as well something that you should expect. One example is touch-less flushing, although none of the pressure-assisted toilets mentioned above have this feature. With such a toilet, you don’t have to push a button or twist a lever to flush. You wave your hand on the side of the tank where you have a sensor, and it gets the job done.

There are as well variations in the type of seat that you get. Some are soft-close and thus barely make a noise when closing. Others are quick-release and can be detached quickly for cleaning purposes.

These are just but a few examples. If you encounter others and they are beneficial to your use of the toilet, you can add them to a list of desirable features. This should as well play a significant role in the toilet purchase decision you make.


In some cases, the pressure in the tank builds up to the point where it can’t be contained. When this happens, the top of the tank will explode, and vitreous china pieces will be launched all over the bathroom. If someone is around when this happens, it could lead to serious injury. However, this rarely happens.

The pricing for pressure-assist toilets isn’t the same for all models. However, expect to pay several hundred dollars to own one. Between $300 and $400 is the most common price range.

Our Verdict

Just like the list above shows, the American Standard 2467016.020 Cadet is our favorite option. We love that it gets the job of flushing done with relative ease. It is also reasonably priced when compared to other toilets with similar benefits.

The Kohler K-3493-0 Highline gives people looking for variable color options something to smile about. The construction is as well top-notch and worth the money. Lastly, we also like the bowl height.

Close after the K-3493-0 is the Zurn Z5572, which is the ideal dual flush pressure-assisted toilet. If you find the 15 3/8 inches bowl height comfortable, you will enjoy having this toilet. Also, the 10-year guarantee is not a bad addition to the list of features.

If we were forced to pick one option from the lineup, it would probably be one of those three depending on various factors. Some of you may not agree with that assessment and have other toilets you feel would be better suited for your needs. You can share your favorite selections with us in the comments section and, if possible, add the reasons why they are your top picks.
