The American Standard Cadet 3 is the everyday workhorse in the brand's lineup, the model plumbers and homeowners reach for when they want a dependable, water-efficient flush without paying premium money. It pairs a 3 inch flush valve with a fully glazed 2 1/8 inch trapway and a high-efficiency 1.28 gallon flush, a combination tuned for clean, quiet performance on most household loads. This review breaks down its MaP flush-test score, water use, EverClean glaze, install quirks and the consistent themes across thousands of aggregated owner reviews, so you can decide whether the Cadet 3 belongs in your bathroom.
The American Standard Cadet 3 is the toilet to buy when you want a reliable, water-saving flush at a sensible price. Its 3 inch flush valve and glazed 2 1/8 inch trapway clear an 800 to 1000 gram MaP load on just 1.28 gallons, it carries EPA WaterSense certification, and EverClean glaze keeps the bowl cleaner. It is an everyday performer, not a brute-force clog specialist.
Research updated June 2026.
American Standard has built toilets in the United States for well over a century, and the Cadet 3 is the model the brand leans on for high-volume, real-world value. Where the Champion 4 chases raw clog-busting power and the smart-bidet models chase luxury, the Cadet 3 was engineered around a quieter promise: a strong, efficient, dependable flush that does the job day after day without drama and without a premium price tag. It is the toilet that shows up in new builds, remodels, rentals and bulk apartment orders, precisely because it gets the fundamentals right at a sensible cost.
Before getting into the details, it helps to anchor on the one number that lets you compare any toilet on equal footing. MaP, short for Maximum Performance, is an independent flush test that measures how many grams of solid waste a toilet clears in a single flush. A score of 600 grams is workable, 800 grams is strong, and 1000 grams is the practical ceiling for a residential gravity toilet. Depending on the configuration, the Cadet 3 lands in the strong-to-excellent 800 to 1000 gram band, which is why it appears in our pillar guide to the best flushing toilets and in nearly every value-focused roundup we publish. This review walks through whether that everyday-workhorse reputation holds up against the published specs and the aggregated owner record, and where the toilet falls short.
This review is not based on lab testing in our own bathroom, and we will not pretend it is. We build it from published American Standard specifications, independent MaP flush-test data, EPA WaterSense certification status, and the consistent themes that surface across thousands of verified owner reviews. We weigh flush power against water use, then factor in trapway width, flush valve size, ease of cleaning, install difficulty and how the design holds up after years of daily service. Where the Cadet 3 has a genuine weakness, we say so plainly.

Flush power is the first thing most buyers care about, so it is the right place to start. The Cadet 3 is built around a 3 inch flush valve, which is a meaningful step up from the 2 inch valve found in most builder-grade toilets. Valve diameter matters because it controls how fast water leaves the tank and enters the bowl. A 3 inch opening empties the tank quickly, creating a fast surge that drives a clean siphon and rinses the bowl in one decisive motion. American Standard pairs that valve with a flush tower that lifts out of the way cleanly, so nothing throttles the water on its way out. The result is a flush that punches above the toilet's modest price.
That 3 inch valve is the mechanical reason the Cadet 3 posts an 800 to 1000 gram MaP score, depending on the exact SKU and trim. In practical terms, that range means it clears even heavy single loads in one flush in most cases, putting it firmly in the strong category alongside toilets like the TOTO Drake and Kohler Cimarron. Aggregated owner reviews echo the lab numbers consistently: the recurring theme is a clean, complete flush with very few mentions of double-flushing under normal use. The Cadet 3 earns a place in our value-flush guides because it delivers that performance on just 1.28 gallons, a balance many pricier toilets cannot match.
Quick tip. Flush valve size is one of the most overlooked specs when people shop for a toilet. The Cadet 3's 3 inch valve moves water into the bowl far faster than the 2 inch valve in most builder-grade toilets, and that speed is a big part of why it rinses the bowl so cleanly. If a listing does not state the valve size, it is almost always a 2 inch.
The second half of the flush story is the trapway, the curved internal channel that carries waste out of the bowl and into your drain line. A narrow trapway is the single most common place a toilet clogs, because anything bulky has to squeeze through a tight bend. The Cadet 3 uses a 2 1/8 inch fully glazed trapway, wider than the roughly 2 inch passage in many standard toilets and coated with a slick glaze that reduces friction and scale buildup. Combine that channel with the fast 3 inch valve, and you get a toilet that pushes typical household loads through cleanly without stalling.
In aggregated reviews, a low clog rate under normal use is a consistent point of praise for the Cadet 3, and it is the reason the model is so often recommended for everyday family bathrooms and rentals. It is worth being honest about where it sits in the lineup, though: the Cadet 3 is not the maximum clog specialist that the wider-trapway Champion 4 is. For households fighting recurring stoppages or very heavy paper use, the Champion 4 or a top-MaP TOTO is the safer pick. For the large majority of homes with healthy plumbing, the Cadet 3's clog resistance is more than enough, which is why it anchors so many of our value guides. If clogs are your specific worry, our American Standard Champion 4 review covers the brand's dedicated clog-buster in detail.
Water use is one of the Cadet 3's strongest selling points, and it is the reverse of the Champion 4's trade-off. The mainstream Cadet 3 flushes on 1.28 gallons per flush, the modern high-efficiency standard, and carries EPA WaterSense certification. WaterSense is the EPA program that certifies toilets using 1.28 gallons or less while still meeting strict flush-performance criteria, so the label means the Cadet 3 saves water without sacrificing the clean flush. Over a year of family use, the difference between 1.28 and 1.6 gallons adds up to thousands of gallons saved, which shows up directly on the utility bill.
What makes the Cadet 3 notable is that it reaches a strong MaP score on that reduced volume, rather than leaning on extra water to do the work. That efficiency is why it fits naturally alongside the top performers in our best EPA WaterSense toilets guide. There is a 1.6 gallon Cadet 3 variant produced for some markets and replacement scenarios, but the version most buyers will find and want is the WaterSense-certified 1.28 gallon model. For buyers in regions with strict water rules, or anyone simply watching their bills, the Cadet 3 is an easy fit where the higher-volume Champion 4 is not.
Worth knowing. Not every Cadet 3 listing is identical. The line spans 1.28 gallon WaterSense models, a 1.6 gallon variant, round and elongated bowls, standard and right-height bowls, and both two-piece and one-piece bodies. Always confirm the GPF figure, WaterSense status and bowl height on the exact SKU before you order so the toilet matches your priorities.
The Cadet 3 leans practical and unfussy, and its design choices reflect that. It is sold in both elongated and round-front bowls. The elongated bowl is more comfortable for adults, while the round-front version saves a few inches of projection in a tight room, which makes the round Cadet 3 a popular pick for compact bathrooms and powder rooms. Many Cadet 3 configurations use American Standard's Right Height bowl, which sits at roughly 16 1/2 inches to the rim and meets ADA requirements, while standard-height versions remain available for households with small children. That comfort-height option places the seat closer to a standard chair rise, which is easier on the knees and a reason the model appears in our best comfort height toilets guide.
On cleaning, the Cadet 3 has a genuine edge over budget toilets thanks to American Standard's EverClean glaze. EverClean is an antimicrobial surface baked into the china that inhibits the growth of stain- and odor-causing bacteria, mold and mildew on the bowl. It is not self-cleaning, and you will still scrub the toilet, but it slows buildup between cleanings compared with a plain vitreous china finish. The fully glazed 2 1/8 inch trapway also resists the scale buildup that narrows passages over time. The standard Cadet 3 is a two-piece toilet, so it has a tank-to-bowl seam and the gap behind the tank that collect dust, though American Standard also offers a concealed-trapway Cadet 3 and one-piece variants for buyers who want a more seamless, wipe-in-one-pass body.
One design feature worth highlighting is the availability of a Cadet 3 with a concealed, skirted trapway. On a skirted toilet, the porcelain side of the bowl is smooth and continuous from the base to the seat, hiding the bends and crevices of the trapway that are exposed on a standard toilet. That smooth skirt is much faster to wipe down and eliminates the awkward channels where dust and grime collect, which is why skirted designs are increasingly popular in modern bathrooms. The Cadet 3 skirted models pair that easy-clean body with the same 3 inch valve and efficient 1.28 gallon flush, so you get the cleaning benefit without giving up flush performance. They show up in our best skirted toilets roundup for exactly that reason.
The main caveat with the skirted version is installation. Most skirted toilets, including the Cadet 3 skirted, mount with a special bracket system rather than dropping straight onto standard closet bolts, so the install is slightly different from a conventional toilet. It is still a manageable DIY job, but it is worth reviewing the bracket instructions before you start. For most buyers, the everyday standard Cadet 3 remains the simplest and most affordable choice, with the skirted model being the upgrade for those who prioritize a clean, modern look.
Installing the standard Cadet 3 follows the same process as any standard floor-mounted toilet: set a new wax ring, drop the bowl onto the closet bolts, level it, connect the tank, and run the supply line. As a two-piece, you assemble the tank to the bowl during the install, which keeps each piece lighter to maneuver than a single heavy one-piece. The Cadet 3 is a moderately sized toilet, lighter and less bulky than the Champion 4, so it is one of the easier models to handle solo. The standard 12 inch rough-in keeps it compatible with most existing setups, and aggregated owner reviews rarely flag installation itself as a problem on the conventional models.
On long-term value, the Cadet 3 makes one of the strongest cases in its price class. American Standard is an established brand with broad parts support, the Cadet 3 uses widely available fill and flush valves, and it is backed by a solid warranty. The combination of a strong flush, low 1.28 gallon water use and a sensible price is exactly what makes it a favorite for landlords, builders and budget-conscious homeowners who need to outfit a whole house. Most owner complaints that do surface tend to involve the fill valve or flapper aging over years of use, both of which are inexpensive, universally available parts that take minutes to swap. Check the current price on Amazon to see how it compares against the alternatives below.
The Cadet 3 is the toilet we recommend most often to people who just want a good, reliable flush without overthinking it. It is not the flashiest or the most powerful, but the blend of a strong 3 inch valve, WaterSense 1.28 gallon efficiency, EverClean glaze and bargain pricing is hard to beat for a standard family bathroom. If you are outfitting a rental or a whole house, this is the model that gives you the least to worry about per dollar spent. Save the Champion 4 budget for the one bathroom that actually has a clog history.
The Cadet 3 is sold in enough configurations that picking the right one is part of getting good value. The plain two-piece Cadet 3 at 1.28 gallons is the high-volume value pick. There are round-front and elongated bowls, standard and right-height options, concealed-trapway skirted versions for easier cleaning, and one-piece bodies for a seamless look. Because the differences in bowl shape, height and trapway style affect both comfort and cleaning, it is worth matching the SKU to your priorities rather than grabbing the first listing. The good news is that even the upgraded configurations stay reasonably priced, so the Cadet 3 holds its value advantage across the range.
The Cadet 3 is the toilet to buy when you want a reliable, efficient flush at a sensible price. Its 3 inch flush valve and glazed 2 1/8 inch trapway clear an 800 to 1000 gram MaP load on a WaterSense-certified 1.28 gallons, EverClean glaze slows bowl buildup, and the design is offered in everything from compact round bowls to easy-clean skirted bodies.
The trade-offs are easy to live with for most homes. It is not the maximum clog specialist that the wider-trapway Champion 4 is, the standard two-piece has the usual tank-to-bowl seam, and the included fill valve and flapper will eventually age. For everyday family use at this price, those concessions are minor.
Think of the Cadet 3 as the sensible default. It is the toilet we recommend first when someone just wants something good that flushes well and saves water, with no special requirements. If you have a specific clog problem, step up to the Champion 4; if you want a premium swirl and the quietest rinse, look at a TOTO. For everything in between, the Cadet 3 is the value benchmark.
The Cadet 3 is the right call for buyers who want a reliable, efficient, fairly priced toilet for everyday use: families furnishing a main bathroom, landlords outfitting rentals, builders specifying a whole house, and budget-conscious homeowners who do not want to overpay for features they will not use. It suits standard 12 inch rough-in bathrooms, comes in compact round and roomy elongated bowls, and its WaterSense 1.28 gallon flush keeps water bills in check. If you want a toilet that simply works well without fuss, the Cadet 3 is one of the safest picks available.
You should look elsewhere if you have a real history of recurring clogs and want maximum flushing power, if you want a premium quiet swirl and refined styling, or if you specifically want a skirted, seamless body and prefer a different brand's bracket system. In those cases the Champion 4, a TOTO, or a dedicated skirted model makes more sense, and a few rivals are worth a look.
The Cadet 3 is the everyday value pick, but depending on whether you prioritize clog resistance, premium flush quality or comfort-height styling, one of these three may suit you better.

When buyers ask us to settle the Cadet 3 against the field, the honest framing is this: the TOTO Drake flushes a touch more smoothly and the Champion 4 clears more aggressively, but neither beats the Cadet 3 on sheer value for an everyday bathroom. It hits the WaterSense 1.28 gallon target, posts a strong MaP score, cleans easily and costs less than the premium options. Choose it when you want the most dependable performance per dollar rather than a specialist.
Yes, especially as an everyday value pick. It posts a strong 800 to 1000 gram MaP flush score using a 3 inch flush valve and a glazed 2 1/8 inch trapway, runs on a WaterSense-certified 1.28 gallons, adds EverClean antimicrobial glaze, and earns a consistently solid aggregated owner rating around 4.5 out of 5, all at a sensible price.
The mainstream Cadet 3 uses 1.28 gallons per flush and carries EPA WaterSense certification, making it about 20 percent more efficient than older 1.6 gallon toilets. A 1.6 gallon variant is produced for some markets and replacement scenarios, but the version most buyers will want and find is the high-efficiency 1.28 gallon WaterSense model.
No, it resists clogs well for an everyday toilet. Its 3 inch valve and glazed 2 1/8 inch trapway give waste a fast, slick path to the drain, and recurring clogs are uncommon under normal household use. It is not the maximum clog specialist that the wider-trapway Champion 4 is, so homes with a real clog history may prefer that model.
The Cadet 3 is American Standard's efficient everyday workhorse, with a 3 inch valve and 1.28 gallon flush at a lower price. The Champion 4 steps up to an oversized 4 inch valve and wider 2 3/8 inch trapway for maximum clog resistance, usually at 1.6 gallons on the standard model. Pick the Cadet 3 for value and efficiency, the Champion 4 for clog-busting power.
MaP measures how many grams of solid waste a toilet clears in one flush. Around 600 grams is workable, 800 grams is strong, and 1000 grams is the practical ceiling for a residential gravity toilet. The Cadet 3 lands in the strong 800 to 1000 gram band depending on configuration, meaning it clears even heavy single loads in most cases.
It is available in both comfort height and standard height. Many configurations use American Standard's Right Height bowl, which sits at roughly 16 1/2 inches to the rim and meets ADA requirements, placing the seat closer to a standard chair for easier sitting and standing. Standard-height versions remain available for households with small children.
Both. The elongated bowl is more comfortable for adults, while the round-front version saves a few inches of projection, making it a popular choice for compact bathrooms and powder rooms. Confirm the bowl shape on the specific listing, and note that the seat must match the bowl shape if it is not included.
Yes. American Standard offers a Cadet 3 with a concealed, skirted trapway, where the smooth porcelain side hides the bends and crevices of a standard toilet. It wipes clean much faster and looks more modern. The trade-off is a slightly different install using a bracket system rather than standard closet bolts.
It varies by SKU and retailer, so confirm on the specific listing. Some Cadet 3 packages include a matching seat, often a slow-close design, while others sell the bowl alone. If the package does not include a seat, budget for a compatible elongated or round seat to match your chosen bowl shape.
The standard Cadet 3 uses a 12 inch rough-in, the distance from the finished wall to the center of the floor drain, which fits the vast majority of North American bathrooms. Some configurations are offered in 10 inch or 14 inch rough-ins, so confirm the figure on the SKU if your drain location is non-standard.
It is a gravity toilet, so it is far quieter than a pressure-assisted model. Its 3 inch valve produces a fast, noticeable rush of water for a quick flush, but most owners describe the sound as a normal, acceptable gravity flush. It is louder than a gentle swirling Tornado Flush toilet but well within typical household expectations.
EverClean is American Standard's antimicrobial surface, baked into the china, that inhibits the growth of stain- and odor-causing bacteria, mold and mildew on the bowl. It is not self-cleaning and you will still scrub the toilet, but it slows buildup between cleanings compared with a plain vitreous china finish, helping the bowl stay cleaner for longer.
No. The standard model installs like any floor-mounted toilet: set a wax ring, drop the bowl onto the closet bolts, level, connect the tank, and attach the supply line. It is moderately sized and lighter than the Champion 4, so it is easy to handle. The skirted version uses a special bracket system, which is a slightly different but still manageable process.
The most common causes are an aging flapper or fill valve. A worn flapper lets water seep from tank to bowl, causing a running toilet, while a misadjusted fill valve can leave the tank underfilled and the flush weak. Both are inexpensive, universally available parts that take only a few minutes to swap, resolving most such complaints.
Both are strong 1.28 gallon performers with cheap universal parts. The TOTO Drake uses the G-Max siphon for a slightly smoother, quieter rinse and a consistent 1000 gram MaP score, while the Cadet 3 matches it on efficiency at a typically lower price. Choose the Drake for refined flush quality, the Cadet 3 for value.
Yes, it is one of the most popular choices for exactly that. The combination of a strong flush, WaterSense 1.28 gallon efficiency, easy-clean glaze, broad parts availability and budget pricing makes it ideal for landlords and builders outfitting multiple bathrooms without overspending. Its low maintenance burden is a key reason it shows up in so many rentals.
American Standard is a long-established North American brand, and many of its toilets, including Cadet-line models, are produced in its US manufacturing operations, though sourcing can vary by SKU and component. The practical takeaway for buyers is broad parts availability and reliable warranty support from a major established manufacturer.
Yes. American Standard backs the Cadet 3 with a limited lifetime warranty on the china and a manufacturer warranty on the mechanical parts. Register your toilet and keep proof of purchase, and confirm the exact warranty terms on the specific model you buy, as coverage can vary by SKU and configuration.
The American Standard Cadet 3 does the most important thing a toilet can do: it flushes well, reliably, and efficiently, at a price almost any household can justify. Its 3 inch flush valve, glazed 2 1/8 inch trapway and strong 800 to 1000 gram MaP score give it a clean, decisive flush on just 1.28 WaterSense-certified gallons, while EverClean glaze, comfort-height options and an easy-clean skirted variant round out a genuinely practical package. The honest caveats are simple: it is not the maximum clog specialist that the Champion 4 is, and it does not carry the premium swirl of a high-end TOTO. For everyday family bathrooms, rentals and whole-house outfitting, the Cadet 3 is one of the easiest recommendations in the category and the value benchmark against which we judge the rest.
