Kohler Cimarron vs American Standard Cadet 3

When homeowners start shopping mid-range two-piece toilets, two names come up constantly: the Kohler Cimarron and the American Standard Cadet 3. Both models have been around long enough to accumulate thousands of real-world reviews. Both carry EPA WaterSense certification. Both sit comfortably in the same price bracket. On the surface they look almost interchangeable, yet owners who have lived with each model report meaningfully different experiences.

This comparison pulls together published manufacturer specifications, independent MaP flush-testing data, EPA WaterSense records, and aggregated owner feedback to give you a factual, side-by-side picture. We cover flushing performance, bowl design, water usage, rough-in compatibility, seat height, ease of installation, warranty coverage, and the scenarios in which each toilet makes the most sense. For a broader look at the category, see our guide to the best flushing toilets on the market today.

Which toilet flushes better: the Kohler Cimarron or the American Standard Cadet 3?

MaP (Maximum Performance) testing is the most objective apples-to-apples measure of toilet flushing power available to consumers. Conducted by an independent testing organization (map-testing.com), MaP tests each toilet by flushing soybean paste in incremental amounts until the bowl fails to clear fully in one flush. A score of 600g is considered acceptable for residential use; 800g is solid; 1,000g is the maximum and indicates the toilet can handle virtually any single-flush demand.

The Kohler Cimarron's Class Five flushing system uses a 3.25-inch flush valve -- significantly larger than the standard 2-inch valve found on older gravity-feed designs -- combined with a wide, direct trapway. The result is a fast-release, high-volume flush that moves waste quickly with minimal delay. The Cimarron's canister-style flush valve seals from the top rather than a flapper, which also reduces the surface area exposed to chlorine degradation and means fewer seal replacements over time.

The American Standard Cadet 3 uses a gravity-flush mechanism with American Standard's PowerWash rim scrub. A dedicated siphon jet at the base of the bowl combines with angled rim holes to scrub the bowl surface during every flush. In MaP testing the Cadet 3 reliably clears 800 grams, which covers almost all typical household scenarios. The 3-inch fully glazed trapway reduces internal friction and is one reason the Cadet 3 earned a reputation as a notably clog-resistant toilet in its price segment.

Are both toilets EPA WaterSense certified and equally water-efficient?

EPA WaterSense is a voluntary program that certifies toilets meeting two criteria: they must use no more than 1.28 gpf AND pass an independent performance test (minimum 350-gram MaP equivalent under WaterSense protocol). Both the Cimarron and Cadet 3 satisfy both conditions, meaning neither sacrifices meaningful flush performance in the pursuit of water savings.

Kohler also offers the Cimarron in a dual-flush configuration (Cimarron Dual Flush) with a 1.0 gpf liquid flush and a 1.28 gpf solid flush. American Standard offers the Cadet 3 in dual-flush as well, at the same 1.0 / 1.28 gpf split. If maximizing water savings is a priority, either dual-flush variant achieves greater savings on liquid flushes without compromising solid-waste removal.

For households replacing older 3.5 gpf or 5 gpf toilets from the 1980s and 1990s, either toilet represents a dramatic efficiency upgrade. The EPA estimates that toilets account for nearly 30 percent of indoor household water use, making 1.28 gpf fixtures one of the highest-impact single upgrades available.

How do the bowl design and seat height of the Kohler Cimarron compare to the Cadet 3?

Bowl height terminology differs slightly by brand. Kohler calls it "comfort height" while American Standard calls it "right height" -- both refer to bowls with a rim height between 16 and 18 inches, which aligns with standard chair height and is generally easier for adults and people with mobility limitations to use. Standard height toilets (roughly 14 to 15 inches) are often preferred by children or shorter adults.

The Kohler Cimarron elongated bowl measures approximately 29.5 inches from the wall to the front of the bowl. The American Standard Cadet 3 elongated model measures roughly 28.5 to 29 inches depending on configuration. If your bathroom is tight on floor space, the Cadet 3 may fit more comfortably within existing constraints. Both brands offer round bowl configurations that shave approximately 2 inches off the front-to-back dimension.

Bowl interior surface matters for hygiene and cleaning frequency. The Kohler Cimarron uses Kohler's standard vitreous china glaze, which is durable and easy to clean but does not include an antimicrobial surface treatment as a standard feature. American Standard applies EverClean surface technology to many Cadet 3 models -- a proprietary glaze embedded with antimicrobial agents designed to inhibit the growth of bacteria, mold, and mildew on the bowl interior. Owners who prioritize low-maintenance cleaning will find the EverClean surface a notable advantage, though regular cleaning remains important for either toilet.

Which toilet is easier to install: the Kohler Cimarron or the American Standard Cadet 3?

Two-piece toilets in this category follow a predictable installation sequence: set the wax ring, lower the bowl onto the floor flange bolts, tighten the nuts, attach the tank, connect the water supply, and test. Neither toilet requires specialty tools or skills beyond what a confident DIYer already has.

Both models are available in 10-inch, 12-inch, and 14-inch rough-in configurations, covering the vast majority of existing bathroom plumbing layouts. The standard rough-in in North American homes is 12 inches (measured from the finished wall to the center of the floor drain). If you are replacing an older toilet and are unsure of your rough-in, measure from the wall (not the baseboard) to the center of the floor bolts before purchasing.

One installation difference worth noting: the Kohler Cimarron tank uses a canister-style flush valve rather than a traditional rubber flapper. During initial tank setup, the canister requires proper seating to prevent phantom flushing or incomplete seals. Most users report no problems, but if you are replacing an older flapper-valve toilet for the first time and find canister instructions unfamiliar, the Cadet 3's traditional fill valve and flapper may feel more intuitive. Both brands include detailed installation instructions and accessible customer support lines.

See our Kohler Cimarron full review for model-specific installation tips, and our American Standard Cadet 3 review for additional configuration guidance.

Which toilet has better long-term reliability and warranty coverage?

Kohler offers a lifetime limited warranty on the Cimarron covering the toilet against defects in material and workmanship for as long as the original purchaser owns their home. The canister flush valve, while a newer design than traditional flappers, has accumulated a positive reliability record across thousands of owner reviews. Replacement canisters are widely stocked at major home improvement retailers and are straightforward to swap without calling a plumber.

American Standard backs the Cadet 3 with a similar limited lifetime warranty on the china. The Cadet 3 uses a traditional flapper-style flush mechanism on many configurations -- flappers are among the most frequently replaced toilet parts but are also among the cheapest (typically under $15 at any hardware store) and easiest for homeowners to replace in under 10 minutes.

Long-term owner feedback aggregated across major retail platforms and plumbing forums consistently rates both toilets above average for reliability. Common complaints on the Cimarron center on occasional canister seal wear after several years. Common complaints on the Cadet 3 involve flapper replacement frequency in areas with hard water or high chlorine. Neither issue is unusual for gravity-flush toilets in their price range, and both are inexpensive fixes.

For comparison context, premium brands like TOTO (with the Drake and Drake II lines) use Double Cyclone and Tornado Flush systems that eliminate rim holes entirely and reduce biofilm accumulation points. The TOTO UltraMax II represents a step up in both MaP performance and long-term maintenance ease at a higher purchase price. The Woodbridge T-0001 and Swiss Madison Sublime offer alternatives in the one-piece segment. See our Kohler vs American Standard brand comparison for full-brand analysis across product lines.

Flushing mechanism deep dive: Class Five vs PowerWash

Understanding the engineering behind each toilet's flush system helps explain the MaP score difference and the practical performance gap between the two models.

Kohler Class Five: Kohler introduced the Class Five flush system across its residential lineup to address the performance gap that emerged when the industry moved from 3.5 gpf to 1.6 gpf and later 1.28 gpf. At lower water volumes, older flush valve designs could not generate sufficient velocity to clear waste reliably. The Class Five system addresses this by using a 3.25-inch canister valve (versus the standard 2-inch flapper opening) that releases the full tank volume in a fast, controlled surge. The trapway on Cimarron models is engineered to maintain velocity through the siphon. The result is a flush that evacuates the bowl quickly and with enough force to clear solids in a single pass -- hence the consistent 1,000g MaP results.

American Standard PowerWash: American Standard's approach combines a strong siphon jet at the base of the bowl with angled rim holes that direct water in a spiral pattern around the bowl interior. This dual-action wash scrubs the bowl sides during every flush, reducing mineral deposits and biological film that accumulate between manual cleanings. The PowerWash system is effective, and the fully glazed trapway reduces friction on waste moving through the trap, contributing to the Cadet 3's solid 800g MaP performance. It does not reach the 1,000g ceiling, but it handles average household loads without issue.

Both approaches are proven over many years and millions of installed units. The Kohler approach prioritizes peak flush force; the American Standard approach balances flush power with bowl self-cleaning characteristics.

Who should choose the Kohler Cimarron?

The Kohler Cimarron is the stronger choice in the following situations:

• Heavy-use bathrooms: The 1,000g MaP score means the Cimarron is rated to handle the maximum tested load in a single flush. Guest bathrooms, master bathrooms used by multiple adults, or any bathroom where incomplete flushes have been a recurring complaint benefit from that extra capacity.
• Long-term canister valve preference: The Class Five canister valve requires less frequent replacement than rubber flappers because it is not submerged in tank water the same way. In areas with chlorine-treated municipal water, traditional flappers can degrade in as little as two to three years. The canister design outlasts flappers in chlorinated water systems.
• Adult comfort priority: If everyone in the household is an adult and comfort during extended use matters, the slightly longer elongated bowl of the Cimarron is a modest but real ergonomic advantage.
• Contemporary aesthetics: The Cimarron has a cleaner, more streamlined tank silhouette that suits updated bathroom renovations. The Kohler Cimarron Skirted version conceals the trapway entirely for a fully modern look.

Who should choose the American Standard Cadet 3?

The American Standard Cadet 3 is the stronger choice in the following situations:

• Budget-conscious buyers: The Cadet 3 typically retails below the Cimarron and is frequently discounted at major home improvement stores. For homeowners remodeling multiple bathrooms, the savings multiply. Performance at 800g MaP is sufficient for most households.
• EverClean surface preference: If you want built-in antimicrobial surface protection on the bowl interior, Cadet 3 models with EverClean glaze offer something the standard Cimarron does not. This reduces visible staining and biological buildup between cleanings.
• Traditional flapper familiarity: If you are a landlord, property manager, or homeowner who strongly prefers the simplicity of flapper-based flush systems -- because your maintenance team knows them cold -- the Cadet 3 is easier to hand off for repairs.
• Compact elongated footprint: In bathrooms where every inch matters, the Cadet 3's slightly shorter front-to-back dimension can make the difference between a toilet that fits comfortably and one that crowds the vanity or door swing.
• Proven clog resistance at lower cost: The fully glazed 3-inch trapway on the Cadet 3 is one of the widest in its price tier. Homeowners who have had chronic clogging issues with older narrow-trapway toilets often report significant improvement after switching to the Cadet 3.

Real owner feedback: what people actually report

Aggregating reviews across major retail platforms and plumbing enthusiast forums reveals consistent patterns in what owners praise and criticize for each model.

Kohler Cimarron owners frequently highlight:

• Quiet, powerful flush -- many describe it as one of the quietest effective flushes they have experienced in a two-piece toilet
• No clogging in years of regular use, even with older drain lines
• Clean bowl between uses with minimal manual scrubbing needed
• Occasional reports of canister seal wear after three to five years requiring a replacement part costing roughly $15 to $25
• Tank lid fit can feel slightly loose on some units out of the box

American Standard Cadet 3 owners frequently highlight:

• Easy installation, often completed in under an hour by first-time DIYers
• Noticeably better than previous narrow-trapway toilets for clog resistance
• EverClean surface keeps bowl cleaner longer between deep cleanings
• Flapper replacement every two to four years in hard-water or high-chlorine areas
• Occasional reports of water running after flushing due to flapper seal degradation -- a quick and inexpensive fix

Neither toilet generates unusual complaint volume relative to its sales scale. Both have vastly more satisfied owners than dissatisfied ones based on aggregated rating distributions. The issues that do arise for each model are consistent, predictable, and inexpensive to address.

How do these compare to other toilets in the segment?

The Kohler Cimarron and American Standard Cadet 3 both sit in the mid-range two-piece category alongside models from Gerber, Woodbridge, and Swiss Madison. The Gerber Viper, for example, is another strong clog-resistant contender with a fully glazed trapway and is worth considering in the same budget range. See our Gerber Viper review for details.

Moving up the performance ladder, the TOTO Drake and TOTO Drake II consistently achieve 1,000g MaP scores with a double-cyclone flush system that many plumbing professionals consider the gold standard in residential two-piece toilets. The TOTO UltraMax II goes further with a one-piece rimless Tornado Flush design that virtually eliminates the hard-to-clean rim crevices found in both the Cimarron and Cadet 3. TOTO models typically carry a higher retail price but a strong reputation for long-term trouble-free performance.

The Woodbridge T-0001 and Swiss Madison Sublime offer contemporary one-piece skirted designs at competitive prices. Both achieve respectable MaP scores and are worth considering if your primary goal is modern aesthetics over serviceability. For households where maintenance simplicity and parts availability matter most, the two-piece Cimarron and Cadet 3 remain better long-term bets.

What is the MaP score for the American Standard Cadet 3?

The American Standard Cadet 3 earns a MaP score of 800 grams in published testing. This is considered a strong result and well above the 600-gram threshold considered acceptable for residential use. It handles typical household waste effectively in a single flush.

Are both toilets EPA WaterSense certified?

Yes, both the Kohler Cimarron and American Standard Cadet 3 carry EPA WaterSense certification at 1.28 gallons per flush, which is 20 percent below the federal maximum of 1.6 gpf. Both also meet WaterSense minimum performance criteria in independent testing.

What rough-in sizes are available for each toilet?

Both the Kohler Cimarron and Cadet 3 are available in 10-inch, 12-inch, and 14-inch rough-in configurations. The 12-inch rough-in is standard in most North American homes. Measure from the finished wall to the center of the floor drain bolts before ordering to confirm which size you need.

What is the seat height of the Kohler Cimarron comfort height model?

The Kohler Cimarron comfort height model has a rim height of approximately 16.5 inches, which is within the ADA-recommended range when a toilet seat is added. This makes it ergonomically suitable for most adults and users with mobility considerations.

Does the Kohler Cimarron come with a toilet seat?

Most standard Kohler Cimarron configurations are sold as toilet only, without a seat. Kohler sells coordinated seats separately, including the Cachet and Brevia elongated seats commonly paired with the Cimarron. Always confirm whether your specific configuration includes a seat before purchasing.

Does the American Standard Cadet 3 come with a toilet seat?

Some Cadet 3 configurations are sold as complete kits including a slow-close elongated seat, while others are sold as toilet only. Check the specific product listing for your chosen configuration. American Standard's slow-close seat is a commonly requested upgrade and is also available separately.

What is EverClean surface on the American Standard Cadet 3?

EverClean is American Standard's proprietary antimicrobial surface treatment applied to the vitreous china glaze. It contains an agent that inhibits the growth of bacteria, mold, and mildew on the bowl interior. American Standard warrants the EverClean surface will not wear off under normal residential use for the life of the product.

What type of flush valve does the Kohler Cimarron use?

The Kohler Cimarron uses a canister-style flush valve (part of the Class Five flushing system) rather than a traditional rubber flapper. The canister seals from the top and uses a 3.25-inch opening for fast water release. It is generally more durable than rubber flappers in chlorinated water environments.

What type of flush valve does the American Standard Cadet 3 use?

The Cadet 3 uses a traditional gravity-flush mechanism with a rubber flapper valve on most configurations. Flappers are among the most commonly replaced toilet parts but can be purchased at any hardware store for a few dollars and replaced in under 10 minutes. In hard water or high-chlorine areas, flappers may need replacement every two to four years.

Is the Kohler Cimarron ADA compliant?

Comfort height models of the Kohler Cimarron meet ADA height requirements when a standard toilet seat is added, bringing the total seat height into the ADA-specified 17-to-19-inch range. Standard height Cimarron models do not meet ADA height requirements for accessibility purposes.

Is the American Standard Cadet 3 ADA compliant?

Right Height models of the Cadet 3 meet ADA height requirements with an appropriate seat installed. The Cadet 3 is also available in standard height configurations for users who prefer or need a lower bowl. Always specify right height when ordering if ADA accessibility is a requirement for your bathroom.

Which toilet is better for clog prevention?

Both toilets use a 3-inch fully glazed trapway, which is among the wider options in the mid-range two-piece category. The Kohler Cimarron's higher MaP score and Class Five flush system give it an advantage in maximum single-flush capacity, but both toilets significantly outperform older 2-inch trapway designs in clog resistance for everyday household use.

Can I use a standard toilet seat on both the Cimarron and Cadet 3?

Both toilets use standard bolt-hole spacing (5.5 inches center-to-center), which is the universal standard for residential toilet seats in North America. Elongated seats fit elongated bowls and round seats fit round bowls. Any standard-fit toilet seat in the correct shape will work on either toilet.

How do the Kohler Cimarron and Cadet 3 compare to the TOTO Drake?

The TOTO Drake achieves a 1,000g MaP score, matching the Cimarron, and uses TOTO's G-Max flush system with a wide 3-inch flush valve. The Drake II and UltraMax II add TOTO's Tornado Flush for a completely rimless bowl design that eliminates hard-to-clean rim crevices found in both the Cimarron and Cadet 3. TOTO models typically retail at a higher price point than either the Cimarron or Cadet 3.

What warranty does Kohler offer on the Cimarron?

Kohler provides a lifetime limited warranty on the Cimarron covering defects in materials and workmanship for the original residential purchaser. This covers the vitreous china body and, under many configurations, flushing mechanism components. Kohler customer service is accessible for warranty support and replacement parts guidance.

What warranty does American Standard offer on the Cadet 3?

American Standard provides a limited lifetime warranty on the Cadet 3 vitreous china under normal residential use. Mechanical seat components may carry a shorter warranty period depending on configuration. American Standard has a well-established replacement parts distribution network for long-term owner support.

Is the Kohler Cimarron available as a one-piece toilet?

No. The Kohler Cimarron is a two-piece toilet. Kohler's one-piece offerings in a similar performance tier include the Kohler Santa Rosa and Kohler San Souci. The Cimarron Skirted provides a partial one-piece visual effect while remaining a two-piece construction internally.

Does the American Standard Cadet 3 come in a one-piece version?

No, the Cadet 3 is a two-piece toilet. American Standard's one-piece options include the American Standard Studio and the Vormax one-piece, which uses American Standard's high-performance Vormax flush technology. One-piece models are easier to clean due to the absence of the seam between tank and bowl.

Which toilet is easier to clean?

The American Standard Cadet 3 with EverClean surface has a practical cleaning advantage because the antimicrobial glaze resists staining and biofilm between manual cleanings. The Kohler Cimarron's standard glaze is smooth and effective but does not include antimicrobial treatment. For deep rim cleaning, both two-piece models have conventional rim holes that benefit from periodic attention with a toilet brush.
