Top Rated Toilets 2026: What Consumer Data Shows

Eight models that consistently score highest across MaP flush testing, EPA WaterSense certification, aggregated owner satisfaction, and independent reliability data. No brand sponsorships. No inflated scores.

Why Trust Best Flushing Toilets

Research updated June 2026.

Quick Answer

The TOTO Drake II leads consumer satisfaction data for two-piece toilets with a MaP score of 1,000 grams at 1.28 GPF, while the Kohler Cimarron and American Standard Champion 4 rank highest for value. For one-piece buyers, the TOTO UltraMax II and Woodbridge T-0001 dominate aggregated ratings.

Choosing a toilet from a wall of options at the hardware store is genuinely difficult. Manufacturers publish MaP scores, GPF ratings, trapway dimensions, and flush technology marketing language that can all point in different directions. This guide cuts through that noise by anchoring every pick to published MaP flush-test data, EPA WaterSense certification status, and aggregated owner feedback from tens of thousands of verified purchases.

The models below represent the consistent top performers across those independent data sources. They come from TOTO, Kohler, American Standard, Woodbridge, Swiss Madison, and Gerber, each a brand with substantial reliability track records and warranty support in North America. For a broader look at the full category, see our best flushing toilets guide.

What does a MaP score actually measure?

MaP (Maximum Performance) testing is an independent laboratory protocol that measures how many grams of solid waste a toilet can flush completely in a single flush, using a standardized soybean-paste and toilet paper media. Scores range from 250 to 1,000 grams, and toilets scoring 800 or higher are considered excellent for residential use. A score of 1,000 grams is the maximum rating and indicates the toilet cleared the full test load without any residue.

MaP testing, published at map-testing.com, is the closest thing the industry has to an objective flush-power benchmark. Unlike manufacturer marketing claims, MaP scores are generated by independent engineers and listed in a publicly searchable database. Every model in this roundup has a published MaP score of 800 grams or higher. Several achieve the full 1,000-gram rating.

Expert Take

A toilet's MaP score is the single most predictive data point for long-term clog resistance. Owner reviews support this: toilets with MaP scores at 800 or below generate significantly more "frequent clog" complaints than those scoring 1,000 grams. The difference in GPF between a 1.6 GPF and a 1.28 GPF toilet is much less important than trapway diameter and flush valve geometry when it comes to real-world performance.

Which toilet brands consistently rank highest in owner satisfaction surveys?

Across aggregated owner review data from major retailers, TOTO consistently ranks highest for overall satisfaction, with the Drake and UltraMax lines earning the most five-star reviews among two-piece and one-piece categories respectively. Kohler ranks second, driven by the Cimarron and Highline Arc. American Standard holds strong in the value segment, particularly the Champion 4, which leads its price tier in clog-resistance satisfaction.

Brand reputation in the toilet category tracks closely with flush-system engineering investment. TOTO's G-Max and Tornado Flush systems, Kohler's Class Five flushing technology, and American Standard's PowerWash rim design each represent genuine engineering differences, not just marketing. The brands that invest most heavily in flush system R&D tend to produce the highest MaP scores and the lowest long-term complaint rates.

Are high-efficiency 1.28 GPF toilets as powerful as older 1.6 GPF models?

Yes, in most cases. MaP testing consistently shows that the top 1.28 GPF models achieve 1,000-gram scores identical to the best 1.6 GPF toilets. The efficiency improvement comes from optimized flush valve geometry and trapway design rather than brute water volume. The EPA WaterSense program certifies 1.28 GPF toilets only after they demonstrate flush performance meeting the MaP 350-gram minimum, and the leading models far exceed that floor.

The shift from 1.6 GPF to 1.28 GPF toilets has been one of the most impactful plumbing changes of the past two decades. EPA WaterSense-certified toilets at 1.28 GPF use 20 percent less water than standard 1.6 GPF models, and 60 percent less than pre-1994 toilets that used up to 3.5 GPF. A household of four replacing a 3.5 GPF toilet with a 1.28 GPF model can save roughly 13,000 gallons of water annually according to EPA WaterSense program data.

Expert Take

The American Standard Champion 4 is one of the few remaining 1.6 GPF models that ranks among the top performers. It earns that spot because its 2-3/8-inch glazed trapway is the widest available on a consumer toilet, and its PowerWash rim scrubs the bowl on every flush. For households with older sewer lines where drain pitch is less than ideal, the Champion 4's extra water volume can provide a meaningful operational advantage.

Best Overall

TOTO Drake II Two-Piece Toilet (CST454CEFG)

4.8 Best for: Most households replacing any older toilet

The TOTO Drake II holds a 1,000-gram MaP score at 1.28 GPF and is EPA WaterSense certified, making it the rare toilet that tops both the efficiency and flush-power charts simultaneously.

Flush SystemG-Max 1.28 GPF
MaP Score1,000 grams
WaterSenseCertified
Bowl ShapeElongated
Seat HeightComfort (16.5 in)
Pros
  • Maximum 1,000-gram MaP score at only 1.28 GPF
  • EPA WaterSense certified for rebate eligibility
  • SoftClose seat available as add-on
  • Comfort height suits most adults
  • Wide availability of replacement parts
Cons
  • Two-piece design means more seams to clean
  • Tank lid can rattle if not seated properly
  • Seat sold separately on most SKUs

The Drake II uses TOTO's G-Max flushing system, which channels water through a large 3-inch flush valve and a fully glazed 2-1/8-inch trapway. The result is a single-flush clearance rate that owner reviews consistently describe as "never clogs." Across thousands of verified purchases, complaint rates for incomplete flushes fall well below the category average.

The comfort height bowl at 16.5 inches suits adults and older users who find standard 15-inch bowls difficult. Installation is straightforward for a DIY replacement on a 12-inch rough-in, and TOTO's parts availability is excellent, with fill valves and flush valves widely stocked at major plumbing suppliers. The Drake II is the default recommendation for any household that wants reliability without premium pricing.

Expert Take

The Drake II's long track record is its strongest argument. It has held the top or near-top position in MaP testing across multiple model year updates, and TOTO's SanaGloss coating option reduces the frequency of deep cleaning needed. For landlords and homeowners alike, it is the safest single-toilet purchase in the market.

Check price on Amazon
Bottom Line: The Drake II earns its top-rated status through independently verified 1,000-gram flush performance, WaterSense efficiency, and an ownership track record spanning more than a decade.
#2
Best One-Piece

TOTO UltraMax II One-Piece Toilet (MS604114CEFG)

4.7 Best for: Buyers who prioritize easy cleaning and sleek looks

The UltraMax II delivers the same 1,000-gram MaP performance as the Drake II in a seamless one-piece profile that eliminates the tank-to-bowl joint where grime accumulates.

Flush SystemG-Max 1.28 GPF
MaP Score1,000 grams
WaterSenseCertified
Bowl ShapeElongated
ProfileOne-piece seamless
Pros
  • No tank-to-bowl seam eliminates a common leak point
  • SoftClose seat included on select models
  • 1,000-gram MaP score matched to Drake II
  • Easier to wipe down and sanitize
Cons
  • Heavier than two-piece, requires two people for installation
  • Higher price point than the Drake II

One-piece toilets have one significant structural advantage: the tank and bowl are manufactured as a single vitreous china unit, which removes the rubber gasket between tank and bowl that is a common failure point in two-piece designs. The UltraMax II takes full advantage of this, pairing that structural integrity with TOTO's proven G-Max flush system.

Owner feedback frequently cites the ease of bathroom cleaning as the top satisfaction driver. The absence of crevices at the tank-bowl joint and the SoftClose seat hinge prevents the seat from slamming while also eliminating a zone that collects bacteria. For master bathrooms and guest bathrooms where aesthetics matter, the UltraMax II's cleaner silhouette consistently outperforms comparable two-piece models in satisfaction surveys.

Expert Take

The UltraMax II is functionally the same toilet as the Drake II with a premium form factor. If your budget allows for it, the one-piece design's long-term maintenance advantages more than justify the price difference. The tank-to-bowl joint on a two-piece toilet is the most common source of minor leaks over a 10-year ownership horizon.

Check price on Amazon
Bottom Line: The UltraMax II is the best one-piece toilet in the consumer market by combined MaP performance, owner satisfaction, and long-term reliability data.
#3
Best Clog Resistance

American Standard Champion 4 Two-Piece Toilet

4.7 Best for: Households with frequent clog issues or older drain systems

The Champion 4 holds the largest trapway in its class at 2-3/8 inches and scores a full 1,000 grams on MaP testing, producing one of the most clog-resistant gravity-flush systems available for residential use.

Flush SystemChampion 1.6 GPF
MaP Score1,000 grams
Trapway2-3/8 inch glazed
Bowl ShapeElongated
WaterSenseNot certified (1.6 GPF)
Pros
  • Widest trapway in the residential market (2-3/8 inch)
  • 1,000-gram MaP score
  • Excellent for older homes with slower drain lines
  • EverClean antimicrobial surface inhibits bacteria growth
  • Strong name recognition; parts widely available
Cons
  • 1.6 GPF is not WaterSense eligible
  • Higher water use than 1.28 GPF competitors
  • Seat quality on base models is average

The Champion 4 is the default recommendation for one specific use case: homes where toilets clog repeatedly despite using normal amounts of toilet paper. The combination of a 1.6 GPF flush and the 2-3/8-inch trapway creates exceptional hydraulic force through the trap, making partial blockages far less likely to accumulate into full clogs. For households with four or more members or with children who use excessive paper, the water savings trade-off against a 1.28 GPF model may be worth it.

American Standard's EverClean surface finish is a durable antimicrobial coating that resists mold, mildew, and bacteria growth on the bowl surface. Independent testing has shown the coating remains effective for years under normal use. Combined with the PowerWash rim that directs water around the full circumference of the bowl rather than just through front-facing holes, the Champion 4 stays cleaner between manual cleanings than most competitors.

Expert Take

The Champion 4 is the toilet plumbers most often recommend to clients who call about recurring clogs. Its trapway diameter advantage is measurable and real. The trade-off is water efficiency, so it is best suited to homes with genuine drainage challenges, not as a universal first choice.

Check price on Amazon
Bottom Line: The Champion 4 is the strongest gravity-flush clog-resistance toilet available for residential use, earning its place despite the higher water use.
#4
Best Kohler

Kohler Cimarron Comfort Height Two-Piece Toilet

4.6 Best for: Buyers who prefer Kohler and want WaterSense efficiency

The Kohler Cimarron earns a 1,000-gram MaP score at 1.28 GPF and carries EPA WaterSense certification, making it the strongest entry in Kohler's value-oriented two-piece lineup.

Flush SystemClass Five 1.28 GPF
MaP Score1,000 grams
WaterSenseCertified
Bowl ShapeElongated
Seat HeightComfort Height (16.5 in)
Pros
  • 1,000-gram MaP at 1.28 GPF
  • WaterSense certified
  • Kohler's Class Five flush system is proven reliable
  • Wide color availability
Cons
  • Seat sold separately on many SKUs
  • Supply line not included

Kohler's Class Five flushing technology uses a 3-1/4-inch piston action flush valve that generates strong hydraulic flow through the 2-1/8-inch fully glazed trapway. The Cimarron combines this proven mechanism with a comfort height bowl and wide color availability including Biscuit, Almond, and several other finish options beyond the standard White and Cotton White.

Owner reviews for the Cimarron consistently cite flush reliability and quiet operation as the top positives. The tank refill noise on Kohler's fill valve design is notably quieter than average, which matters in bathrooms adjacent to bedrooms. The toilet's straightforward two-piece design means replacement parts are stocked by virtually every plumbing supplier and hardware chain in North America. See our best flushing toilets for the money guide for how the Cimarron compares on value per dollar.

Expert Take

The Cimarron sits in an excellent position in the market: it delivers 1,000-gram MaP performance, carries WaterSense certification, and benefits from Kohler's parts ecosystem and brand warranty support, all at a mid-range price point. For buyers loyal to Kohler's design aesthetic, this is the performance benchmark in the line.

Check price on Amazon
Bottom Line: The Cimarron is the strongest performer in Kohler's two-piece lineup and represents a high-confidence purchase for shoppers committed to the Kohler ecosystem.

Best Water Savings

TOTO Aquia IV Dual-Flush Two-Piece Toilet

4.6 Best for: Buyers with high water costs or drought-conscious households

The Aquia IV offers 1.0 GPF / 0.8 GPF dual-flush options with a published MaP score of 1,000 grams on the full flush, delivering class-leading water savings without sacrificing flush power.

Flush SystemDual-flush 1.0/0.8 GPF
MaP Score1,000 grams (full flush)
WaterSenseCertified
Bowl ShapeElongated
Annual SavingsUp to 20% vs 1.28 GPF
Pros
  • 0.8 GPF half flush for liquid waste
  • Full 1,000-gram MaP on the 1.0 GPF flush
  • TOTO CeFiONtect glaze on many configurations
  • WaterSense certified
Cons
  • Dual-flush buttons take adjustment for new users
  • Full flush at 1.0 GPF has less hydraulic margin than 1.28 GPF

The Aquia IV uses TOTO's double-cyclone flush system, which generates flush action through two nozzles rather than traditional rim holes. This creates a spiral water movement that uses volume more efficiently, which is how TOTO achieves 1,000-gram MaP performance at just 1.0 GPF. In households where the 0.8 GPF half-flush is used for the majority of flushes, annual water consumption can drop significantly compared to standard 1.28 GPF single-flush models.

Some users find the dual-flush button mechanism on the tank lid requires a brief learning curve. The small button triggers the 0.8 GPF flush and the large button the 1.0 GPF flush. Owner reviews occasionally note that household visitors unfamiliar with dual-flush controls use the wrong button. This is a minor usability consideration, not a performance issue. TOTO's CeFiONtect glaze option on the Aquia IV creates an exceptionally smooth surface that resists waste adhesion, reducing how often the bowl needs manual cleaning.

Expert Take

The Aquia IV's 0.8 GPF partial flush is the most water-efficient gravity-flush option currently available in a full-featured residential toilet with a legitimate 1,000-gram full-flush rating. For high-frequency-use bathrooms in multi-person households, the cumulative water savings over a 10-year lifespan are substantial.

Check price on Amazon
Bottom Line: The Aquia IV is the strongest dual-flush option on the market for buyers who want maximum water savings without a MaP performance penalty.

Best Modern Design

Woodbridge T-0001 One-Piece Toilet

4.5 Best for: Modern bathroom renovations with a design-forward aesthetic

The Woodbridge T-0001 delivers a skirted, concealed-trapway design with an 800-gram MaP score, EPA WaterSense certification, and a soft-close seat included, making it a strong all-in value for contemporary bathroom remodels.

Flush SystemDual-flush 1.28/0.8 GPF
MaP Score800 grams
WaterSenseCertified
ProfileSkirted one-piece
SeatSoft-close included
Pros
  • Skirted design conceals trapway for a clean visual profile
  • Soft-close seat included at no additional cost
  • Dual-flush 1.28/0.8 GPF
  • WaterSense certified
Cons
  • 800-gram MaP lower than TOTO and Kohler top picks
  • Parts availability narrower than major brands
  • Warranty support takes longer than TOTO or American Standard

The T-0001's skirted design hides the trapway behind a smooth exterior wall, creating a visual profile that looks significantly more expensive than the actual price point. The soft-close seat is a meaningful inclusion, as most competing toilets at this price require a separate seat purchase. The dual-flush mechanism offers 1.28 GPF for solid waste and 0.8 GPF for liquid, which aligns with WaterSense requirements.

The 800-gram MaP score is the main performance limitation relative to TOTO and Kohler alternatives. For most average households this is adequate, but heavy-use bathrooms or households with children may find the margin for clog resistance narrower. Woodbridge is a younger brand relative to the major players, and parts availability at local plumbing suppliers is more limited, making DIY repairs more dependent on online sourcing. For design-focused buyers who understand these trade-offs, the T-0001 is the most accessible modern skirted toilet in the market. For a deeper look, our best flushing skirted toilets guide compares it against Kohler's skirted options.

Expert Take

The Woodbridge T-0001 is the right answer when design is the primary purchase driver and flush performance is secondary. Its 800-gram MaP score is sufficient for most households, and the included soft-close seat plus skirted profile make it a genuinely compelling package for bathroom remodels on a budget.

Check price on Amazon
Bottom Line: The T-0001 is the strongest design-value combination in the skirted one-piece category, best suited for remodel projects where aesthetics and price matter more than peak flush performance.

Best Budget Pick

American Standard Cadet 3 Two-Piece Toilet

4.5 Best for: Rental properties and secondary bathrooms on a budget

The Cadet 3 hits a 1,000-gram MaP score at 1.28 GPF with WaterSense certification, making it one of the most cost-efficient high-performing toilets available and the logical choice for landlords and builders.

Flush SystemCadet 3 Flush 1.28 GPF
MaP Score1,000 grams

Bowl OptionsRound or elongated
Rough-in12-inch standard
Pros
  • 1,000-gram MaP at an accessible price point
  • Available in both round and elongated bowl
  • WaterSense certified
  • American Standard brand parts widely available
Cons
  • Basic aesthetics without premium detailing
  • Seat quality on base models is functional but not premium

The Cadet 3 is a workhorse toilet that consistently exceeds expectations given its price positioning. Its 1,000-gram MaP score means it matches the flush performance of toilets costing significantly more, and the WaterSense certification keeps operating costs low. American Standard's broad parts distribution means that any fill valve or flapper failure can be addressed with a trip to any hardware store rather than an online parts order.

The round bowl version is particularly useful for small bathrooms where the 2-inch shorter length of a round bowl creates meaningful clearance advantages. Landlords and builders who equip multiple units frequently choose the Cadet 3 for its combination of performance, low maintenance, and established parts availability. See our best toilets for rental properties guide for how it compares in that specific context.

Expert Take

The Cadet 3 is the best argument that premium flush performance does not require a premium price. Its 1,000-gram MaP score at 1.28 GPF WaterSense means it objectively outperforms many toilets sold at two or three times its cost.

Check price on Amazon
Bottom Line: The Cadet 3 is the highest-performing toilet per dollar in the residential market, earning its place as the default choice for value buyers and landlords.

Plumber's Choice

Gerber Viper Two-Piece Toilet

4.4 Best for: Buyers who want professional-grade specification at a residential price

The Gerber Viper achieves 1,000 grams on MaP testing at 1.28 GPF with WaterSense certification and has a long track record as a professional plumber's specification choice for both residential and light commercial installations.

Flush SystemViper Flush 1.28 GPF
MaP Score1,000 grams
WaterSenseCertified
Bowl ShapeElongated
WarrantyLifetime limited
Pros
  • 1,000-gram MaP score
  • Lifetime limited warranty
  • Preferred by professional plumbers for specification installs
  • WaterSense certified 1.28 GPF
Cons
  • Less visible brand in retail compared to TOTO and Kohler
  • Narrower color selection

Gerber Plumbing has a strong reputation among professional plumbers that does not always translate into equivalent consumer brand awareness. The Viper toilet consistently appears on plumber forum recommendation threads as a high-reliability alternative to the major consumer brands. Its 1,000-gram MaP score at 1.28 GPF WaterSense is verified by independent testing, and the lifetime limited warranty provides strong long-term protection.

For buyers who discover Gerber through a plumber's recommendation, the Viper is a legitimate high-performance option that deserves inclusion alongside the better-known brands. The narrower retail distribution is the main practical limitation, as parts and the toilet itself may require ordering rather than local pickup at a hardware chain. For professional installation projects, however, the Gerber Viper is a proven workhorse.

Expert Take

Gerber's lower consumer profile belies the genuine quality of the Viper. Plumbers who work across brands daily often specify Gerber when they want professional-grade reliability without the premium pricing of TOTO. The lifetime limited warranty is one of the strongest in the category.

Check price on Amazon
Bottom Line: The Gerber Viper is a professional-grade toilet that earns its spot through independent MaP testing, WaterSense efficiency, and a lifetime warranty, even if the brand name is less familiar to consumers.

What is EPA WaterSense certification and does it matter for toilet performance?

EPA WaterSense is a certification program administered by the U.S. Environmental Protection Agency that verifies a toilet uses no more than 1.28 GPF and meets minimum flush performance standards in independent testing. WaterSense certification matters for two practical reasons: it is required for most municipal water-utility rebate programs, and the performance floor it sets (minimum MaP 350 grams) eliminates underperforming models. All WaterSense toilets must be independently tested and certified by an EPA-recognized third party.

Homeowners who replace toilets with WaterSense certified models may qualify for rebates from their local water utility, which can reduce the net cost of a toilet substantially. The EPA maintains a searchable product database at epa.gov/watersense where certified models are listed with their specifications. When evaluating a specific model, cross-referencing the EPA WaterSense list and the MaP testing database together provides the most complete picture of both efficiency and performance credentials.

How do one-piece and two-piece toilets compare in long-term reliability?

Two-piece toilets have a gasket seal between the tank and bowl that can develop minor seeping leaks over time, typically after 10 to 15 years. One-piece toilets eliminate this joint entirely, which removes a common long-term failure point. However, two-piece toilets are easier to transport and install since the tank and bowl are handled separately, and replacement parts are often more readily available. Both designs can last 25 or more years with normal maintenance.

Expert Take

The one-piece versus two-piece decision is less about flush performance, which can be identical, and more about installation logistics, cleaning preference, and budget. The tank-to-bowl joint on a two-piece is a real long-term maintenance consideration, but it is also an easy repair when it does fail. For most homeowners, the two-piece design's lower price and easier DIY installation make it the default choice unless cleaning ease or aesthetics justify the one-piece premium.

Frequently Asked Questions

What is the highest MaP score a toilet can receive?

The maximum MaP score is 1,000 grams. A toilet that achieves 1,000 grams has cleared the full test load of solid media in a single flush without any residue. Multiple models from TOTO, Kohler, American Standard, and Gerber achieve this maximum rating at 1.28 GPF.

Which toilet brand is most reliable long-term?

TOTO has the strongest long-term reliability reputation based on aggregated owner review data and plumbing industry surveys. Kohler ranks second. Both brands have parts ecosystems that remain well-stocked for decades, which supports long-term ownership. American Standard has strong reliability in its core lines and is the most widely stocked brand for parts at general hardware retailers.

Is a 1.28 GPF toilet powerful enough for a family of four?

Yes. The top 1.28 GPF toilets achieve 1,000-gram MaP scores, which is the same flush power rating as the best 1.6 GPF models. A family of four is well within the design parameters of a 1,000-gram MaP toilet operating at 1.28 GPF.

What trapway size should I look for to prevent clogs?

A glazed trapway of at least 2-1/8 inches is the standard for high-performance residential toilets. The American Standard Champion 4 offers the widest available at 2-3/8 inches. All trapways in the top-rated models are fully glazed, which reduces friction and prevents waste from adhering inside the trap.

Do dual-flush toilets clog more often than single-flush models?

Not necessarily. The full flush on dual-flush toilets like the TOTO Aquia IV achieves 1,000-gram MaP performance. Clog issues in dual-flush toilets typically arise when users use the partial flush for solid waste. Using the correct flush mode for the waste type prevents most issues.

How do I know if my toilet qualifies for a water utility rebate?

Check your local water utility's website for rebate programs. Most require the toilet to carry EPA WaterSense certification. The EPA WaterSense website at epa.gov/watersense also maintains a rebate finder tool that lists available programs by zip code.

What is the difference between comfort height and standard height toilets?

Standard height toilets measure 15 to 15.5 inches from floor to seat rim. Comfort height toilets measure 16 to 18 inches, closer to the height of a standard chair. Comfort height is now more common in new installations and is preferred by taller adults and users with knee or hip mobility limitations.

Are skirted toilets harder to install than standard exposed-trapway designs?

Skirted toilets typically require a bolt-down installation kit that attaches to the floor flange before setting the toilet, rather than the traditional wax ring method. Some models include this kit; others require a separate purchase. The process is manageable as a DIY install but takes slightly more planning than a standard installation. Most skirted toilets come with manufacturer instructions that walk through the specific method.

Which toilet is best for elderly or mobility-limited users?

Comfort height models at 16 to 18 inches are easiest for users with limited knee or hip mobility. ADA-compliant toilets at 17 to 19 inches provide additional height. The TOTO Drake II and Kohler Cimarron both offer comfort height configurations. For a deeper guide, see our ADA compliant toilet guide.

What does EPA WaterSense certified mean on a toilet?

It means the toilet has been independently tested and verified to use 1.28 GPF or less while meeting minimum flush performance requirements set by the EPA. Certification is not self-reported; it requires laboratory testing by an EPA-recognized third party. WaterSense certified toilets are listed in the EPA's online product database.

How long does the average toilet last before needing replacement?

The vitreous china bowl and tank on quality toilets can last 50 or more years without structural failure. Internal mechanisms including the fill valve, flapper, and flush valve typically need replacement every 5 to 10 years depending on water quality and usage. Most owners replace toilets for efficiency or aesthetic reasons before the porcelain fails.

Is it worth spending more on a TOTO versus a Kohler or American Standard?

In the mid-range and up, TOTO's flush technology and CeFiONtect glaze coating deliver real, measurable advantages in flush consistency and bowl cleanliness. At the budget tier, the American Standard Cadet 3 and Kohler Highline match TOTO MaP scores at lower price points. The decision depends on whether the additional features of TOTO's coatings and flush systems justify the premium for your specific situation.

What is TOTO CeFiONtect and does it make a difference?

CeFiONtect is TOTO's proprietary glaze coating applied to the bowl surface. It creates an extremely smooth, ion-barrier surface that reduces the adhesion of waste, bacteria, and mineral deposits. Independent testing supports TOTO's claims that CeFiONtect-glazed bowls require less frequent scrubbing and maintain appearance longer than standard glaze finishes.

Can I put a bidet seat on any of these toilets?

Yes, all standard toilet seats are compatible with bidet seat attachments as long as the bowl shape matches (round bidet seat for round bowl, elongated for elongated). All eight models on this list are available in elongated bowl, which is the most common bidet seat size. Ensure the bowl dimensions match the bidet seat manufacturer's specifications before purchasing.

What is the rough-in measurement and how do I find mine?

The rough-in is the distance from the finished wall behind the toilet to the center of the floor drain. The standard residential rough-in is 12 inches. Measure from the wall to the center of the two flange bolts on either side of your existing toilet to confirm. Most toilets fit 12-inch rough-ins; homes with 10-inch or 14-inch rough-ins require specific models.

How do I compare MaP scores when shopping for a toilet?

The MaP testing database at map-testing.com allows you to search by manufacturer and model to find the published MaP score for specific toilets. Scores are listed in grams; a minimum of 800 grams is considered excellent for residential use, and 1,000 grams is the maximum. Always verify the specific SKU, as some models have multiple flush configurations with different scores.

Are pressure-assist toilets worth considering over gravity-flush models?

Pressure-assist toilets use compressed air stored in a sealed tank to add force to the flush, which can improve performance in low-water-pressure situations. However, they are louder than gravity-flush models and cost more to purchase and maintain. The top gravity-flush models on this list achieve 1,000-gram MaP scores that match or exceed pressure-assist performance for typical residential use, making pressure-assist a niche recommendation rather than a universal upgrade.

Our Verdict

For most households, the TOTO Drake II is the highest-confidence toilet purchase available today. Its independently verified 1,000-gram MaP score at 1.28 GPF, EPA WaterSense certification, comfort height bowl, and decade-long reliability track record make it the default recommendation. Buyers who prioritize cleaning ease should step up to the UltraMax II one-piece. Households with clog-prone drain lines should consider the American Standard Champion 4's wider trapway. Budget buyers and landlords get maximum flush performance per dollar from the American Standard Cadet 3. Every model on this list is backed by published MaP data and carries an established brand warranty.
