Kohler K-3978-0 Wellworth Toilet
Make the most of each flush with the powerful Kohler Wellworth Classic. This two-piece pressure-assisted toilet earns high marks from reviewers for its strong, thorough flushing and reliable handling of solids. Equipped with an elongated seat and Flushmate pressure tank technology, you’ll get both comfort and performance from this toilet.
Each flush uses 1.6 gallons of water per flush, and while it has a louder flush than conventional toilets, this model is designed with noise-mapping and frequency analysis to minimize noise levels.

American Standard Champion White Elongated Standard Height Toilet 12-in Rough-In Size

Best One Piece
Kohler San Raphael Comfort Height Single Flush Elongated Toilet
The Kohler San Raphael is a one-piece pressure-assisted toilet that has a low-profile tank to further add to its space-saving nature. A one-piece toilet like this model offers a space-saving solution for more compact bathrooms, powder rooms, and water closets. In addition, the unibody design of this toilet blends the tank and seat into one piece and reduces the number of cracks and crevices—making it easier to clean.
This chair-height toilet has an elongated bowl and comes in seven different shades of vitreous china, including black, grey, and almond color selections to match your décor. It uses just 1 gallon of water per flush, though some reviewers complain that, at times, this leaves toilet paper behind if it doesn’t land in the center of the bowl. In general, however, reviewers looking for a one-piece pressure-assisted toilet have been satisfied with this model and also report that the flush is quieter than other models.

Best Two Piece
Zurn Vantage 2-Piece Single Flush Elongated Pressure Assist Toilet
While many pressure-assisted toilets are two-piece models that feature a separate tank and seat, the Zurn Eco Vantage stands out for its affordability, conservative water usage, and easy install. Using 1.28 gallons of water for each powerful flush, this toilet effectively clears the bowl and eliminates the hassle of a clogged toilet, according to users.
Keep in mind that most pressure-assisted toilets feature a comparably louder-sounding flush—this is true for the Zurn Eco Advantage and is frequently pointed out by users. At the same time, the audible noise from the pressure-assisted flush only lasts for a moment and the toilet quietly fills for the next use.

Best Chair Height
Kohler Highline Classic Toilet
The Kohler Highline Classic toilet combines a taller seat height and pressure-assisted flushing technology to provide a comfortable and efficient fixture. This model offers a 17-inch seat height, which is about two inches taller than standard height toilets. In addition, the elongated bowl adds to the ergonomics of this toilet’s design. The increased water surface area in the bowl (10 inches by 12 inches) also contributes to efficient flushing and a clean bowl.
Reviewers describe sitting on this tall pressure-assisted toilet as comparable to sitting on a throne—one with incredible flushing power. You’ll need to supply your own seat if you opt for this model.

Geberit .8/1.6 GPF Dual Flush 2-Piece Elongated Icera Toilet
If you’re looking for a toilet that (nearly) disappears into the wall, consider a concealed tank pressure-assisted toilet. This option is pricey but minimizes the appearance and space taken up by a toilet in your bathroom or powder room. This pressure-assisted toilet and concealed tank combination from Geberit features an elongated bowl and simple wall plate with dual flush options for liquid or solid waste. The tank sits behind the wall and uses 1.6 gallons of water per flush. You’ll appreciate how simple this wall-hung toilet looks in your bathroom, while also benefiting from the pressure-assisted flushing mechanism tucked behind the wall.
While a concealed tank pressure-assisted toilet will cost you more than $800, the look and function are well worth the price tag and give any bathroom a clean, modern look.
What to Look for
A big advantage of pressure-assisted toilets is their reduced water usage during flushing. The gallons per flush (GPF) utilized by the toilet to remove waste is one factor to compare when deciding on a pressure-assisted toilet. Most pressure-assisted toilets use between 1 and 1.6 GPF.
Two-piece vs. One-piece Design
Like standard gravity-fed toilets, pressure-assisted toilets come in both two-piece and one-piece designs. A two-piece toilet is standard and involves a tank that is separate from the bowl. One-piece toilets have a tank and bowl that are part of a single fixture. Aesthetic is the largest difference between the two design options, but you'll also find that a one-piece toilet can reduce cleaning effort and time.
Pressure-assisted toilets are available in standard and chair-height configurations. A standard toilet usually has a seat that is 15 inches high, but the seat of a chair-height toilet will measure 17 to 19 inches. If you are choosing a new toilet that will be used by taller individuals or those with mobility issues, a chair-height toilet may be the right choice.
How much does a pressure assisted toilet cost?
Usually, pressure-assisted toilets (including the tank and bowl) cost between $300 and $500. Models with a concealed tank may cost upwards of $1,000.
What is the difference between a power- and pressure-assisted toilet?
These terms are interchangeable. You'll most often see these toilets described as 'pressure-assisted' models, but they may also be referred to as power-assisted or power-flush toilets.
How do pressure assisted toilets work?
Pressure-assisted toilets use a sealed plastic tank within the toilet tank to store water under air pressure. When you flush the handle, a forceful flow of water is expelled into the toilet bowl. Air fills the void from the expelled water, and your home's water supply line refills the tank with water. As the tank fills, the water again becomes pressurized—ready to be flushed again.
