We researched the top pressure-assisted toilets on the market, evaluating functionality, design, efficiency, and ease of installation. Our best overall pick, the Kohler K-3978-0 Wellworth Toilet, has a dependably strong flush, an elongated bowl, and comes in several finishes.   Here are the best pressure-assisted toilets. 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. Most users agree that while the flush is audible from outside the bathroom, it is short-lived and well-worth it to avoid clogged toilets and left-behind solids and debris. Price at time of publish: $376 This pressure-assisted elongated toilet uses 1.6 gallons of water per flush; in general, users are very satisfied with its performance. For many, it has eliminated concerns regarding overflows and made the toilet plunger seem obsolete. In addition, this is a one-piece pressure-assisted toilet, reducing the exterior cleaning required to keep the toilet sanitary and spot-free. Price at time of publish: $671 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. Price at time of publish: $1,323 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. Price at time of publish: $521 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. Price at time of publish: $430 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. 

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.

Seat Height

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.
