Changing the toilet in our home is not something that many of us have to do very often, so it’s common to have a lot of questions. The new pressure-assisted toilets are incredible inventions that can all but eliminate the need for a plunger or failed flushes, but you may have questions about installing them and want to know more about how they work.
We’ve assembled a list of six of the most common pressure-assisted toilets that we install regularly, and we are going to let you know what we like and don’t like about each brand, as well as what features they offer.

The 6 Best Pressure Assisted Toilets — Reviews 2020
1. American Standard Cadet Pressure-Assisted Toilet – Best Overall
The American Standard Cadet Pressure-Assisted Toilet is our pick for the best overall pressure-assisted toilet. This model has a pressure-assisted siphon jet that helps reduce clogs and ensures a strong flush. A closed inner tank provides the extra pressure, and the 1.6-gallon tank delivers a strong yet economical flush. Its tall height makes it easy to get up and down, and the elongated seat makes it more comfortable. It comes in two pieces and is easy to install.
Overall, we enjoyed reviewing our American Standard Cadet Pressure-Assisted Toilet, and the only negative thing we could say about it is that you need to purchase the seat and lid separately.
2. Niagara 77001WHCO1 Stealth Toilet – Best Value
The Niagara 77001WHCO1 Stealth Toilet is our pick for the best pressure assisted toilet for the money. This efficient system uses only 0.8 gallons of water to flush and can pay for itself in saved water alone. The flushing system is also extremely quiet when compared to many other pressure-assisted brands, and its compact size will fit in most bathrooms without trouble.
The only negative thing to say about the Niagara 77001WHCO1 Stealth Toilet is that it might be a little small for some people, and it’s surprisingly heavy for its size.
3. Kohler K-3493-0 Elongated Toilet – Premium Choice
The Kohler K-3493-0 Elongated Toilet is our premium choice pressure-assisted toilet. This model is a two-piece toilet that is easy to install and features an elongated bowl for maximum comfort. It features Comfort Height, which means it stans a little taller than most standard models, and it is easier to sit down on or stand up. The 1.6-gallon pressure-assisted toilet quickly evacuates all contents from the bowl.
The Kohler K-3493-0 Elongated Toilet is very similar to our top choice, and like that model, this brand doesn’t come with the seat, so you will need to purchase one separately. This model is also a little more expensive, and the flush trip hand continuously came loose, which requires removing the lid to tighten.
4. TOTO CST744SL#01 Drake 2-Piece Ada Toilet
The TOTO CST744SL#01 Drake 2-Piece Ada Toilet features an economical 11.6-gallon flush, an extra-large flush valve, and the pressure-assist delivers 8-psi water pressure to help evacuate waste and prevent clogs. The two-piece design is easy to install and cheaper to maintain should one of the parts fail or crack. It’s also very lightweight, which helps with the installation.
While we were reviewing the TOTO CST744SL#01 Drake 2-Piece Ada Toilet, we felt that it was a little small for our liking, and the forward sloped tank lid means anything stored there will fall in the toilet. Another thing that we noticed about this brand is that it is one of the loudest on the list, and it’s flush can be heard throughout our entire house.
5. American Standard Cadet Pressure Assisted Two Piece Toilet
The American Standard Cadet Pressure Assisted Two Piece Toilet is the second American Standard on our list. This model features a two-piece design that is easy to install and set up. The elongated bowl uses pressure assisted siphon jets and delivers a powerful but economical 1.6-gallon flush, and the Everclean surface is stain-resistant and easy to wipe down.
The American Standard Cadet Pressure Assisted Two Piece Toilet is a fantastic toilet that we enjoyed reviewing, but it is quite small and may not be suitable for taller or heavier people. We liked the strong initial flush, but the siphon jets didn’t do much to clean the bowl as it was filling back up.
6. Zurn Z5572 Dual Flush Pressure Assist Toilet
The Zurn Z5572 Dual Flush Pressure Assist Toilet is the final model on our list, and this brand gives you the unique ability to choose between a more economical or more powerful flush. Pulling up on the handle results in a 1.1-gallon flush that can save you money over time. Pressing down on the handle provides you with a more powerful 1.6-gallon flush. The two-piece design is easy to transport and install.
The downside to the Zurn Z5572 Dual Flush Pressure Assist Toilet is that it is very low to the ground, and we found it to be the most difficult to get on and off of on this list. Like many of the other brands, this model also does not come with a toilet seat, so you will need to purchase one separately. We also found this model to be extremely loud, and some people may find it off-putting.
Let’s look at some of the most important things to look for when choosing a pressure-assisted toilet.
How Does It Work
Pressure assisted toilets usually have a sealed compartment inside the tank. Aas the tank fills with water pressure builds in the sealed compartment, and the energy is stored until the toilet is flushed. When the toilet is flushed, the sealed compartment releases the pressure and forces the water and waste down the drain in a fast burst. The action is similar to that of a BB-gun or toy rocket. The air escaping from the chamber and forcing waste and water down the drain is what causes the loud swooshing sound that pressure-assisted toilets are known for making.
You will install your pressure-assisted toilet the same way that you install your standard gravity-fed toilet. The toilet bowl sits on a wax ring, and you bolt it to the floor. You attach the tank to the bowl and connect your water supply. The pressure creating mechanism is inside the tank, and it will work automatically, building pressure each time you flush the toilet.
Pressure Assisted Toilet Pros and Cons
Pressure assisted toilets are smaller than the standard gravity feed toilets we are all likely familiar with using. Their smaller size makes them perfect for small-sized rooms without a bath. Pressure assisted toilets got their start in commercial businesses and are well known for their reliability and resistance to clogging due to their powerful flush. The design of thee toilets allows for many uses a day with very little maintenance.
The smaller tank uses less water to create the flush, so it pays for itself over time in water savings. Many toilets will use 1.6 gallons or less to create the flush, with some going as low as 0.1 gallons.
No tank sweat
Less water also equates to less tank sweat in humid environments and during the summer. Many people don’t realize the hazard of tank sweat. It can allow bacteria to grow in the humid environment around the tank and, in some cases, can also cause the wood behind the toilet to swell and warp, causing permanent damage to the wall.
Another benefit to the smaller size of pressure-assisted toilets is that they are usually much lighter than gravity-fed models. That means they are easier to transport, get into place, and install. Most models come in two pieces, so you can install the bowl first, and once It’s in place, you can place the tank on top and secure it.
The downside to using pressure-assisted toilets is that they are relatively new to the market, which means there are far fewer designs available. If you are hoping to get something extravagant or unique, you will most likely need to look for a gravity-fed brand.
Costs and repairs
These toilets use modern technology and employ a complex design that costs more to build, so the toilet will be more expensive to purchase. If something goes wrong, replacement parts will also cost more, and far fewer people have experience with pressure-assisted toilets, so it can be challenging to find knowledgeable help to answer questions or provide assistance.
Another thing to consider before purchasing a pressure-assisted toilet is they can get quite noisy. Most of us are familiar with the loud swooshing sound made by the toilets in fast-food restaurants and many other establishments, and you can expect a similar sound in your home. Some consumer brands combine gravity-fed technology with pressure-assisted technology to keep the noise down, but even these will be loud. We tested several brands that you could hear flush anywhere in our multi-floor home.
One crucial factor to look for in any toilet is the height the bowl is from the floor. If you have never thought about it before, it might be an excellent time to consider how easy it is to get up and down from the toilet. If you are short, you may like your toilet closer to the ground, but we believe many people would like if their toilet was a little taller. Luckily, this is one feature built into many of the modern toilets, and it’s not hard to find one labeled as “tall.”
Tall toilets raise the seat a few inches and can help make it a lot easier to stand up from when finished. These toilets also usually have a larger bowl, which can be a great feature.
How to Choose
When choosing your next pressure-assisted toilet, we recommend starting with the seat height and bowl size. These toilets are often a lot smaller than the ones you are used to, and the chances are good that the toilet you are replacing is a gravity-fed. In our experience, most people prefer the tall model if given a choice, and the taller models usually have larger bowls.
Once you have the height and bowl size you want the rest is about finding a quality brand. Look for brands like American Standard, and Kohler that have been around for a long time and understand people's needs. It’s not just about the pressure created or the toilet's ability to evacuate waste, the connections need to fit, parts need replacing, and problems need solving. You are more likely to get better customer service from a long-standing company.
We highly recommend our top choice for pressure-assisted toilet. The American Standard Cadet Pressure-Assisted Toilet is a tall model that also features an elongated bowl for extra room. American Standard is a highly respected brand that’s been around a long time. The Niagara 77001WHCO1 Stealth Toilet is another excellent choice and it only uses .8-gallons of water per flush, the least on our list. The Niagra is a little small for some people, but its best toilets you can buy for its price.
