TOTO Brand Guide: Every Series, Model and Tech Explained

TOTO is the world's largest toilet manufacturer, founded in Japan in 1917 and now the benchmark for flush performance in North America. This guide covers every major series, proprietary technology, MaP scores, certifications, and how each model positions against Kohler, American Standard, Gerber, and Woodbridge -- so you can choose with confidence.

Why Trust Best Flushing Toilets

Research updated June 2026.

Quick Answer

TOTO leads the residential toilet market on MaP flush performance, surface technology, and manufacturing consistency. The Drake II and UltraMax II both achieve the maximum 1,000-gram MaP score at 1.28 GPF. The Aquia IV is TOTO's best dual-flush water saver. The Neorest line defines the luxury integrated smart-toilet segment for North America.

Who Makes TOTO and Where Are TOTO Toilets Built?

TOTO Ltd. was founded in 1917 in Kitakyushu, Japan, and is now the largest toilet manufacturer in the world by production volume. For the North American market, TOTO operates a manufacturing facility in Morrow, Georgia, where a portion of U.S.-sold products are assembled. Additional production occurs in Japan and China, with the country of origin varying by model and configuration. The company introduced the WASHLET electronic bidet seat in Japan in 1980 and holds hundreds of patents related to flush dynamics, ceramic glaze chemistry, and electronic sanitary ware.

TOTO's North American market presence grew substantially through the 1990s and 2000s as contractors and plumbing professionals recognized that its commercial-grade manufacturing standards transferred directly to residential products. The same quality systems that produce TOTO's commercial building fixtures apply to the Drake and UltraMax II found in homes, which is one reason MaP test scores for TOTO models are consistently at or near the top of the residential category.

The company organizes its North American lineup into three clear tiers: entry-level value (Entrada, Eco Drake), performance mainstream (Drake, Drake II, UltraMax II, Vespin II), and luxury integrated (Carlyle II, Neorest). The Aquia IV sits slightly apart as the brand's dedicated water-efficiency line, optimized for low-GPF performance rather than raw flush power. Understanding that structure makes model selection straightforward once you know your priorities.

Expert Take

TOTO's production consistency is the most important differentiator that does not show up in spec sheets. Unlike some brands that source product from multiple contract factories under a single label, TOTO maintains tight factory control that results in fewer unit-to-unit defects, more predictable flush performance across production batches, and more reliable warranty service. When a plumber recommends TOTO, it is largely this consistency they are endorsing -- not just the technology.

What Flush Technologies Does TOTO Use in Its Toilets?

TOTO uses four primary flush systems in its North American residential line: G-Max (1.6 GPF, original Drake), E-Max (1.28 GPF, Entrada and entry models), Double Cyclone (1.28 GPF, Drake II), and Tornado Flush (1.0-1.28 GPF, UltraMax II, Vespin II, Aquia IV, Neorest). Double Cyclone uses two pressurized rim nozzles to scrub the bowl without traditional rim holes. Tornado Flush advances this with three directional nozzles that generate a centrifugal vortex covering more bowl surface per flush. Both systems eliminate the mineral-clogging rim holes found in conventional gravity toilets.

The elimination of rim holes is not a cosmetic design choice -- it addresses a real long-term maintenance problem. Standard gravity toilets rely on a series of small ports along the underside of the rim to direct water into the bowl during flushing. In hard-water markets, those ports gradually clog with calcium and mineral scale over months or years, progressively weakening the flush without any visible indicator. TOTO's nozzle-based systems are geometrically immune to this problem: there are no small ports to clog, so flush performance does not degrade gradually the way it does in rim-hole designs.

A practical consequence of this design choice is visible in long-term MaP data. Toilets that start at 800-gram MaP scores when new can drop meaningfully over time if rim ports clog. Because TOTO's flush systems do not depend on rim ports, the relationship between as-installed MaP performance and long-term real-world performance is more reliable. This is a meaningful consideration for high-use residential bathrooms and commercial applications.

Expert Take

The upgrade from Double Cyclone (Drake II) to Tornado Flush (UltraMax II, Vespin II) is a genuine one, not just marketing nomenclature. Tornado Flush uses three jets arranged to maximize centrifugal coverage of the bowl walls, which means the bowl gets scrubbed at angles Double Cyclone does not fully reach. Both achieve 1,000 grams in MaP testing, but Tornado Flush does more cleaning work per flush cycle -- the MaP score measures waste removal, not bowl coverage.

What Is CeFiONtect and Does It Make a Measurable Difference?

CeFiONtect is TOTO's proprietary ionic ceramic glaze applied during the kiln-firing stage of toilet production. The glaze creates an ultra-smooth, densely non-porous surface that is significantly more resistant to organic waste adhesion, bacterial growth, and mineral buildup than standard vitreous china. It is a molecular-level surface treatment, not a topcoat, which means it does not wear off with normal cleaning. Owners in hard-water markets consistently report that CeFiONtect bowls require less frequent scrubbing and maintain visual cleanliness longer than comparable Kohler, American Standard, Gerber, and Woodbridge models without equivalent glaze technology.

CeFiONtect's measurable advantage comes from surface physics. Conventional vitreous china has microscopic pores at a scale invisible to the naked eye but accessible to bacteria, mineral ions, and organic particles. CeFiONtect fills those pores at the molecular level, reducing adhesion sites significantly. This is why the glaze's cleaning benefit is most apparent in hard-water conditions: mineral deposits have fewer surfaces to nucleate on, so scale buildup is slower and easier to remove when it does occur.

Competing brands offer comparable surface treatments: Kohler's CleanCoat is applied to select models, and American Standard's EverClean glaze is an antimicrobial surface treatment with silver-ion technology. Among users who have used multiple brands over years, CeFiONtect is generally rated slightly superior in long-term durability, attributed to the firing-stage application method versus topcoat approaches. The EverClean silver-ion treatment has a different mechanism aimed at bacterial growth rather than physical adhesion resistance, so the two address related but distinct problems.

CeFiONtect is indicated in the model number by the letter "C" (for example, "CEFG" suffix). Not all TOTO models include it -- the Entrada line and some round-bowl Drake configurations ship without CeFiONtect at lower price points. When comparing two TOTO models that look identical online, verifying the model number suffix is the fastest way to determine whether CeFiONtect is included.

How Does TOTO Compare to Kohler, American Standard, and Gerber on MaP Flush Testing?

In third-party MaP testing, the TOTO Drake II and UltraMax II both achieve the maximum 1,000-gram score at 1.28 GPF -- equaling the American Standard Champion 4 (which uses 1.6 GPF) and outscoring most Kohler models at comparable GPF. The Kohler Highline Arc typically scores 900 grams at 1.28 GPF, while the Kohler Cimarron matches TOTO's ceiling with its own 1,000-gram score at the same GPF. The Gerber Viper Ultra reaches 1,000 grams but relies on a 1.6 GPF system. TOTO's achievement is reaching 1,000 grams at 1.28 GPF, combining maximum flush force with EPA WaterSense water savings in the same toilet -- a tier the Cimarron also reaches, though with a less advanced glaze package.

MaP scores sourced from map-testing.com published test records. Scores reflect standard single-flush test configuration at published GPF rating.

The table above illustrates the core TOTO value proposition clearly: the only model that matches TOTO's UltraMax II or Drake II on MaP score at 1.28 GPF is the Swiss Madison-class dual-flush market, where scores are typically lower. The American Standard Champion 4 matches the 1,000-gram MaP score but requires 1.6 GPF to do so -- using 25% more water per flush. At identical water usage, TOTO's top-tier models produce stronger documented flush performance than any major U.S. competitor.

What Are the Main TOTO Series and Which Is Right for You?

TOTO's North American residential line spans five primary series: Entrada (entry-level, E-Max flush, no CeFiONtect), Drake (original G-Max 1.6 GPF platform), Drake II (current-generation Double Cyclone 1.28 GPF workhouse), UltraMax II (one-piece Tornado Flush flagship), Aquia IV (dual-flush water efficiency), and Neorest (luxury integrated smart toilet). For most homeowners, the Drake II is the best starting point -- top MaP score, CeFiONtect glaze, ADA height, and the broadest availability of replacement parts. The UltraMax II is the preferred upgrade when one-piece cleaning ease is a priority.

#1
Best Overall

TOTO Drake II Two-Piece Elongated Toilet (CST454CEFG)

4.7 Best for: Most households wanting proven, low-maintenance performance

The Drake II is TOTO's best-selling model for a documented reason: its Double Cyclone flush achieves a 1,000-gram MaP score at only 1.28 GPF, the CeFiONtect glaze resists staining and mineral buildup, and the two-piece construction keeps parts accessible for DIY maintenance over a 20-year service life.

MaP Score1,000 g
GPF1.28
Flush TechDouble Cyclone
Seat Height16.5 in (ADA comfort)
WaterSenseYes
Pros
  • Maximum 1,000-gram MaP score at 1.28 GPF
  • CeFiONtect ionic glaze resists staining and mineral scale
  • Double Cyclone eliminates rim-hole clogging
  • ADA-compliant comfort height
  • Replacement parts widely stocked nationwide
  • EPA WaterSense certified
Cons
  • Two-piece seam collects grime between tank and bowl
  • Toilet seat sold separately on most configurations
  • Exposed trapway harder to clean than skirted designs

The Drake II replaced the original Drake's G-Max 1.6 GPF system with Double Cyclone at 1.28 GPF -- a redesign that simultaneously improved flush performance and reduced water consumption. Instead of relying on volume and gravity, Double Cyclone uses two pressurized nozzles on the rim to generate a rotating water pattern that scrubs the bowl actively during each flush. The result is a MaP score that matches the American Standard Champion 4 while using 25% less water per cycle.

Owner reviews across major retailers consistently place the Drake II near the top for long-term reliability. The most cited reasons are predictable flush performance that does not decline over time, low cleaning frequency due to CeFiONtect, and the availability of replacement fill valves, flappers, and flush valves at hardware stores and plumbing supply houses rather than requiring factory-direct parts. Compared to the best flushing toilets across all brands, the Drake II sits in a select tier that combines maximum MaP score with WaterSense certification.

Expert Take

The Drake II is the toilet independent plumbers most frequently install in their own homes. The flush is consistent across production batches, the glaze holds up in hard-water conditions, and parts availability means a fill valve replacement five years from now is a hardware-store errand rather than a factory call. That combination of performance, durability, and serviceability is what defines a genuinely professional-grade residential product.

Check price on Amazon
Bottom Line: The TOTO Drake II is the standard two-piece residential toilet measured by MaP score, glaze quality, and long-term serviceability -- the right choice for most households.
#2
Best One-Piece

TOTO UltraMax II One-Piece Elongated Toilet (MS604114CEFG)

4.8 Best for: Master bathrooms and households prioritizing easy cleaning and modern aesthetics

The UltraMax II combines TOTO's most powerful flush technology -- Tornado Flush with three directional nozzles -- with a seamless one-piece skirted body that eliminates the tank-to-bowl seam and exposed trapway, achieving the maximum 1,000-gram MaP score in a design that is both higher-performing and easier to clean than the Drake II.

MaP Score1,000 g
GPF1.28
Flush TechTornado Flush
Body TypeOne-piece skirted
WaterSenseYes
Pros
  • Seamless one-piece body with no tank-to-bowl seam to clean
  • Tornado Flush scrubs more bowl surface per cycle
  • 1,000-gram MaP score at 1.28 GPF
  • Skirted trapway removes hard-to-reach grime surfaces
  • SoftClose seat included on most configurations
Cons
  • Significantly heavier than two-piece models (challenging solo install)
  • Higher purchase cost than Drake II
  • Skirted base complicates wax ring replacement versus exposed trapway

Tornado Flush uses three directional rim jets arranged to create a centrifugal vortex that sweeps the full interior of the bowl during each flush. Independent assessments consistently show it leaving less residue on bowl walls than Double Cyclone after simulated high-use cycles. The UltraMax II is not just aesthetically superior to the Drake II -- it does more cleaning work per flush, which matters in busy family bathrooms where cleaning frequency is a real consideration.

Compared to the Woodbridge T-0001 or Swiss Madison one-piece models at similar price points, the UltraMax II carries a substantially higher MaP score and TOTO's full warranty support network. The Woodbridge T-0001 is visually similar and competitively priced, but does not achieve 1,000 grams in MaP testing and lacks the bowl-surface technology that CeFiONtect provides. For buyers comparing best flushing one-piece toilets across all brands, the UltraMax II has held its lead for multiple consecutive model years.

Expert Take

The UltraMax II is the toilet designers and remodelers specify for master bathrooms when the buyer wants a product that performs as well as it looks. The skirted one-piece format has become the standard in premium residential bathroom design, and the UltraMax II is the benchmark in that category -- combining Tornado Flush's rim scrubbing with CeFiONtect to effectively reduce cleaning effort by half versus a conventional gravity flush model.

Check price on Amazon
Bottom Line: The TOTO UltraMax II is the best one-piece toilet available for households where flush performance, bowl cleanliness, and modern design must all be at the highest level.
#3
Best Water Saver

TOTO Aquia IV Dual Flush Two-Piece Toilet (CST746CEMFG)

4.4 Best for: Water-restricted regions and households focused on utility bill reduction

The Aquia IV is TOTO's dedicated water-efficiency model, offering a 1.0 GPF full flush and a 0.8 GPF partial flush via dual push-button activation -- qualifying under California CEC standards and EPA WaterSense dual-flush thresholds while using Tornado Flush to compensate for the lower water volume.

MaP Score1,000 g (full flush)
GPF1.0 / 0.8 dual
Flush TechTornado Flush
CeFiONtectYes (CEMFG models)
WaterSenseYes
Pros
  • 0.8/1.0 GPF among the lowest residential flush volumes available
  • Qualifies for water utility rebates in drought-regulated states
  • Tornado Flush compensates for reduced water volume
  • CeFiONtect glaze critical to performance at low GPF
Cons
  • 0.8 GPF light-flush mode is for liquid waste only, not a lower-power full flush
  • Dual-button operation can confuse guests unfamiliar with dual-flush
  • Two-piece design has a visible tank-to-bowl seam versus a one-piece model

The Aquia IV is the fourth generation of TOTO's dual-flush line and the first to pair Tornado Flush with the 0.8/1.0 GPF configuration. Previous Aquia generations used a more conventional flush mechanism that struggled more noticeably at low water volumes. The Tornado Flush system's pressurized directional jets compensate for the reduced water volume by maximizing hydraulic energy efficiency per gallon -- the same engineering principle that allows the UltraMax II to match the Champion 4's MaP score with 25% less water.

The water savings arithmetic is significant for households in high-rate water markets. A family of four using the Aquia IV's 1.0 GPF full flush instead of a 1.28 GPF toilet saves approximately 2,900 gallons per year. Compared to the original Drake's 1.6 GPF system, annual savings approach 8,000 gallons. In California, Colorado, Nevada, and other states where water utilities offer rebates for high-efficiency toilet replacement, the Aquia IV typically qualifies for rebate programs that offset a meaningful portion of the purchase cost.

Expert Take

The Aquia IV is the right TOTO for a household determined to minimize water consumption without giving up brand quality. The engineering is significantly better than generic dual-flush imports at similar price points -- those products often struggle with the 0.8 GPF partial flush because their flush mechanics were not designed around low-volume efficiency. TOTO built the Aquia IV specifically to perform at low GPF, not to retrofit a standard toilet with a dual-flush button.

Check price on Amazon
Bottom Line: The TOTO Aquia IV is the strongest dual-flush toilet from a major manufacturer, balancing aggressive water savings with Tornado Flush reliability and CeFiONtect glaze.
#4
Best Skirted Two-Piece

TOTO Vespin II Two-Piece Skirted Elongated Toilet (CST474CEFG)

4.5 Best for: Buyers who want skirted aesthetics without the one-piece weight and handling challenge

The Vespin II delivers TOTO's Tornado Flush system and 1,000-gram MaP score inside a fully skirted two-piece body -- solving the practical installation problem of one-piece toilets by allowing the tank and bowl to be transported and installed as separate pieces, then assembled in place.

MaP Score1,000 g
GPF1.28
Flush TechTornado Flush
TrapwayFully skirted
WaterSenseYes
Pros
  • Skirted design without one-piece weight handling difficulty
  • Same 1,000-gram MaP score as UltraMax II
  • Tank and bowl transport separately for stair/tight-space installation
  • CeFiONtect glaze on CEFG model variants
Cons
  • Skirted base requires careful floor sealing at installation
  • Higher cost than Drake II at equivalent spec level

The Vespin II's main competitive advantage is solving a real installation logistics problem. One-piece toilets are substantially heavier and awkward for a single person to maneuver up stairs, around corners, or into a bathroom with tight clearances. The Vespin II allows the tank and bowl to be carried in separately, installed independently, and then connected, making it a genuinely DIY-accessible skirted option in a way that the UltraMax II is not for most homeowners.

From a performance standpoint, the Vespin II runs the same generation Tornado Flush as the UltraMax II and achieves an identical 1,000-gram MaP score. The skirted base is fully sealed and looks visually indistinguishable from a one-piece toilet at standing viewing distance. Buyers comparing best flushing skirted toilets across all brands will find the Vespin II occupies the performance lead for two-piece skirted configurations.

Expert Take

If you want the skirted look and Tornado Flush performance but need to carry the toilet up a flight of stairs, the Vespin II is the pragmatic solution. The performance is equivalent to the UltraMax II -- same flush technology, same MaP score, same glaze -- just in two manageable pieces instead of one heavy unit.

Check price on Amazon
Bottom Line: The TOTO Vespin II is the correct choice for buyers who want the skirted aesthetic and Tornado Flush performance without the one-piece handling challenge.
#5
Best Budget TOTO

TOTO Entrada Close Coupled Round Toilet (CST244EF)

4.2 Best for: Rental properties, basement bathrooms, and TOTO brand reliability on a limited budget

The Entrada is TOTO's entry point: a compact round-bowl two-piece that delivers TOTO's manufacturing consistency and EPA WaterSense certification at the brand's lowest price tier, using the E-Max 1.28 GPF single flush system without CeFiONtect glaze.

MaP Score800 g
GPF1.28
Flush TechE-Max
CeFiONtectNo
Bowl ShapeRound (compact)
Pros
  • TOTO manufacturing quality and production consistency
  • Round bowl suited to small or narrow bathrooms
  • WaterSense certified at 1.28 GPF
  • Simple mechanism and widely available replacement parts
Cons
  • No CeFiONtect glaze -- standard vitreous china
  • E-Max flush lacks the rim-scrubbing action of Double Cyclone or Tornado Flush
  • 800-gram MaP score is competitive but not top-tier

The Entrada's spec sheet is similar to the Kohler Wellworth and American Standard Cadet 3 at this price tier -- all three share comparable MaP scores and GPF ratings. Where the Entrada earns its place is TOTO's production quality: parts fit precisely, the ceramic dimensions are consistent, and the flush mechanism components are TOTO-standard rather than generic imports that vary quality between production batches. For rental property owners, that consistency translates to fewer post-installation service calls.

Buyers who can extend budget should evaluate the Drake II, where Double Cyclone and CeFiONtect deliver a measurably higher performance tier. But for applications where budget is firm and the priorities are reliable daily function and TOTO brand serviceability, the Entrada is a sensible allocation.

Expert Take

The Entrada is a baseline toilet with no notable weaknesses. It will not underperform or need unexpected service calls; it is simply a well-manufactured entry-level product. Anyone who can afford the Drake II should buy the Drake II, but when budget is genuinely constrained, the Entrada is a better long-term choice than comparable-priced models from value-tier brands.

Check price on Amazon
Bottom Line: The TOTO Entrada is the most reliable entry-level toilet in TOTO's lineup, offering brand-quality manufacturing at the lowest price point in the range.

Best Luxury Smart Toilet

TOTO Neorest 750H Integrated Smart Toilet (MS992CUMFG)

4.9 Best for: Luxury master bathrooms where integrated bidet and self-cleaning are priorities

The Neorest 750H integrates tankless Tornado Flush, ewater+ electrolyzed water self-cleaning, auto open/close lid, heated seat, front and rear WASHLET bidet wash, warm air dryer, and deodorizer into a single seamless skirted unit -- the most complete toilet system TOTO produces for residential use.

MaP Score600 g
GPF1.0 / 0.8 dual
Flush TechTornado Flush (tankless)
Self-Cleaningewater+ electrolyzed water
ElectricalRequired (GFCI outlet)
Pros
  • Fully integrated bidet -- no separate seat purchase needed
  • ewater+ mists bowl with antimicrobial electrolyzed water after each use
  • Auto open/close lid eliminates touchpoints
  • Tankless design keeps profile exceptionally clean
  • Heated seat and warm air dryer included
Cons
  • Requires dedicated GFCI electrical outlet near toilet
  • Substantially higher cost than all other TOTO residential models
  • 600-gram MaP score lower than Drake II or UltraMax II
  • Electronic component failure requires professional service

The 600-gram MaP score for the Neorest 750H reflects the tankless flush system's operating principle rather than a performance limitation. Tankless toilets draw directly from the building's water supply line without accumulating stored tank volume, which produces a different hydraulic signature in MaP testing than tank-based systems. In practice, the ewater+ self-cleaning system means the bowl sees far less organic buildup between manual cleaning sessions than any conventional toilet -- so the relevant performance benchmark is different for the Neorest than for the Drake II.

The ewater+ system deserves specific attention for health-conscious households. After each flush, the unit mists the bowl surface with weakly acidic electrolyzed water produced by an onboard electrolysis cell. This mist reduces bacterial adhesion and organic buildup without any cleaning chemicals or user intervention. For households with immunocompromised members, the continuous passive antimicrobial treatment has genuine hygiene value beyond the luxury experience that the Neorest otherwise represents.

Expert Take

The Neorest 750H is what four decades of TOTO flush engineering and twenty years of WASHLET development produce when combined in a single product. The electrical requirement is real and must be planned for -- but once installed, it delivers a bathroom experience that is categorically different from any conventional toilet at any price. For a luxury master bath renovation where the buyer budget supports it, it is the correct specification.

Check price on Amazon
Bottom Line: The TOTO Neorest 750H is the most complete integrated toilet experience available from any manufacturer -- justified for luxury master bathrooms where electrical access exists and the budget supports it.
#7
Best for Small Bathrooms

TOTO Drake Original Two-Piece Round Toilet (CST744SG)

4.3 Best for: Half baths and powder rooms where projection space is the binding constraint

The original Drake round-bowl format is approximately 2 inches shorter front-to-back than the elongated Drake II, using the proven G-Max 1.6 GPF flush system that built TOTO's North American reputation -- making it the right TOTO choice when bathroom geometry rules out an elongated bowl.

MaP Score900 g
GPF1.6
Flush TechG-Max
Bowl ShapeRound (compact projection)
WaterSenseNo (1.6 GPF)
Pros
  • Compact round bowl saves 2 inches of projection versus elongated
  • G-Max has decades of documented residential reliability
  • 900-gram MaP score strong for a round-bowl format
  • Lower acquisition cost than Drake II
Cons
  • 1.6 GPF does not meet EPA WaterSense threshold
  • G-Max uses rim holes (less cleaning coverage than Double Cyclone)
  • No CeFiONtect on standard configurations

The round-bowl Drake predates TOTO's Double Cyclone redesign and uses the G-Max system with a 3-inch flush valve and 2.125-inch fully glazed trapway. For buyers in jurisdictions without 1.28 GPF mandates, the G-Max's 900-gram MaP score at 1.6 GPF is a reliable choice with twenty years of field reliability data behind it. Buyers in California and other states with strict water-use regulations must verify local code compliance before purchasing the 1.6 GPF format.

The round bowl format is primarily a geometry decision rather than a preference. Elongated bowls are generally more comfortable for adult use, but round bowls fit bathrooms where the distance from the rough-in to the door or wall leaves less than 30 inches of clearance from the bowl front. For those specific bathroom configurations, the Drake round is the correct TOTO specification and consistently leads the best flushing round toilets category at its price tier.

Expert Take

When the bathroom floor plan forces a round bowl, the original Drake is the correct TOTO answer. G-Max is not as refined as Tornado Flush or Double Cyclone, but two decades of residential reliability data give it a track record that matters more than technology on paper for a low-complexity half-bath installation.

Check price on Amazon
Bottom Line: The TOTO Drake round bowl is the most reliable compact toilet in TOTO's lineup for space-constrained bathrooms, built on the G-Max platform that established TOTO's North American market position.

Understanding TOTO Model Number Suffixes

TOTO model numbers encode configuration details that determine exactly what you receive. The suffix "#01" indicates Cotton White finish; "#12" is Sedona Beige; "#11" is Colonial White. "CEFG" or "CEMFG" in the model name indicates CeFiONtect glaze is included. "EF" indicates E-Max flush at 1.28 GPF. "SF" indicates a SoftClose seat is included. "G" or "GR" indicates the configuration includes a SoftClose seat with pre-drilled holes. Buyers who compare TOTO models online must verify the full model number to avoid purchasing a visually identical toilet that omits CeFiONtect or the SoftClose seat, since these differences are not always obvious in product photos.

TOTO Color Options

TOTO's three primary residential colors are Cotton White (#01), Colonial White (#11), and Sedona Beige (#12). Cotton White is TOTO's most popular finish and reads as a bright, slightly cool white -- closer to Kohler's White than to Kohler's Biscuit or Almond. Colonial White is a warmer mid-tone white. Sedona Beige is a warm tan suited to traditional bathroom color schemes. Buyers matching a TOTO toilet to existing Kohler or American Standard fixtures should note that TOTO does not offer a Bone equivalent -- if the existing tile is in Kohler Bone or American Standard Linen, a color chip comparison is essential before ordering.

TOTO Warranty Coverage

TOTO provides a one-year limited warranty on most residential product parts and a three-year limited warranty on vitreous china components against manufacturing defects. WASHLET and Neorest electronic components have separate warranty terms published by TOTO USA. Warranty service is processed through TOTO's U.S. customer service network, with authorized service centers in major metropolitan markets. This compares to Kohler's one-year limited warranty and American Standard's limited lifetime warranty on select premium lines. In practice, TOTO's parts availability through nationwide plumbing supply houses means that out-of-warranty repairs are cost-effective and do not require factory-direct ordering.

Frequently Asked Questions

Is TOTO a Japanese brand?

Yes. TOTO Ltd. was founded in 1917 in Kitakyushu, Japan, and remains a Japanese company. For North America, TOTO operates a manufacturing facility in Morrow, Georgia, where a portion of U.S.-sold products are assembled. Some models are manufactured in Japan or China. Country of origin varies by model and is disclosed on product packaging.

What does TOTO stand for?

TOTO is derived from the Japanese words "Toyo Toki," meaning "Oriental Ceramics." The company began as a porcelain manufacturer and transitioned to sanitary ware in its early decades. Today TOTO is the largest toilet manufacturer in the world by production volume.

Which TOTO toilet has the best flush performance?

The TOTO Drake II and UltraMax II both achieve the maximum 1,000-gram MaP score at 1.28 GPF -- the highest tier of third-party verified flush performance available in a WaterSense-certified toilet. The Vespin II also achieves 1,000 grams with Tornado Flush. The Neorest 750H scores lower at 600 grams due to its tankless system design, not a performance limitation.

What is the difference between the TOTO Drake and Drake II?

The original Drake uses the G-Max 1.6 GPF flush system with a conventional rim-hole design. The Drake II replaces it with Double Cyclone at 1.28 GPF, eliminating rim holes entirely with a two-nozzle pressurized system that improves bowl scrubbing while using less water. The Drake II carries EPA WaterSense certification; the 1.6 GPF Drake does not.

Is TOTO better than Kohler for flush performance?

By third-party MaP test scores at equivalent GPF, it's closer than brand loyalists on either side admit. TOTO's Drake II and UltraMax II both score 1,000 grams at 1.28 GPF, and Kohler's Cimarron matches that ceiling at the same GPF, while the Highline Arc trails at approximately 900 grams. Kohler has broader design variety and a larger accessory ecosystem; TOTO's edge shows up in glaze technology (CeFiONtect) and bidet integration rather than in raw flush numbers, since the top models from both brands now tie at the top of the MaP scale.

What is CeFiONtect and is it worth the extra cost?

CeFiONtect is TOTO's ionic ceramic glaze applied during kiln firing. It creates a denser, smoother surface with fewer microscopic pores, making it substantially harder for waste, bacteria, and mineral deposits to adhere. Owners in hard-water markets consistently report less cleaning frequency with CeFiONtect bowls versus untreated vitreous china. For households that clean bathrooms weekly, the reduced cleaning labor over the toilet's 20-year life generally justifies the incremental cost.

Does the TOTO Drake II come with a toilet seat?

Most Drake II base configurations are sold without a seat. TOTO sells compatible SoftClose seats separately, including WASHLET+ integrated models for buyers who want bidet functionality. Some bundle configurations at specific retailers include a seat -- verify the full model number listing before purchasing to confirm what is included.

What is Tornado Flush versus Double Cyclone?

Double Cyclone uses two pressurized nozzles to generate a rotating rinse pattern that scrubs the bowl without rim holes. Tornado Flush advances this with three directional nozzles arranged to create a more powerful centrifugal vortex that covers a larger percentage of the bowl interior per flush. Tornado Flush is used in the UltraMax II, Vespin II, Aquia IV, and Neorest. Double Cyclone is used in the Drake II.

Is the TOTO Aquia IV a good choice for clog resistance?

The Aquia IV scores a perfect 1,000 grams in MaP testing on its 1.0 GPF full flush, matching the ceiling set by the Drake II and UltraMax II despite using less water per flush. Tornado Flush's pressurized jets deliver that score with strong clog resistance relative to conventional gravity dual-flush toilets at similar GPF. For households with consistently heavy solid waste, all three -- the Aquia IV, Drake II, and UltraMax II -- provide the same maximum flush margin; the choice between them comes down to one-piece versus two-piece design and dual-flush water savings rather than flush power.

Are TOTO toilets EPA WaterSense certified?

Most current TOTO residential models are EPA WaterSense certified. The original Drake in 1.6 GPF format is not, as 1.6 GPF exceeds the WaterSense threshold of 1.28 GPF or less. All Drake II, UltraMax II, Aquia IV, Vespin II, and Neorest configurations meet WaterSense criteria. Verify any specific model against the EPA WaterSense product list at epa.gov/watersense before purchase.

What rough-in size do TOTO toilets require?

Most TOTO residential models are designed for the standard 12-inch rough-in. TOTO also produces select models in 10-inch and 14-inch variants, identified by model number suffix. Measure your existing rough-in distance before purchasing -- if replacing a 14-inch rough-in toilet, a conversion spacer plate can bridge the gap without floor modification on some configurations.

What is ewater+ in the TOTO Neorest line?

Ewater+ is TOTO's proprietary electrolyzed water system found in the Neorest series. The toilet passes tap water through an electrolysis cell to produce weakly acidic water that acts as a mild antimicrobial agent. This water automatically mists the bowl before and after each use, reducing bacterial adhesion and organic buildup without cleaning chemicals. It is one reason the Neorest requires less manual cleaning than conventional toilets despite its lower MaP score.

How does TOTO WASHLET+ differ from a standard WASHLET seat?

Standard TOTO WASHLET seats (C100, C200, S500e) are compatible with most elongated or round-bowl toilets and require a separate visible supply line and electrical cord. WASHLET+ seats integrate with specific TOTO toilet bases to fully conceal the electrical cord and water line within the toilet's structure, producing a clean finished appearance without visible connections. WASHLET+ is not compatible with non-TOTO bowls.

Can a WASHLET seat be added to any TOTO toilet?

Standard WASHLET seats (non-WASHLET+) are compatible with most elongated or round TOTO bowls, provided the bowl dimensions fall within standard ranges. WASHLET+ models with integrated connection routing are designed for specific compatible TOTO bowls and should not be used on incompatible bases. TOTO publishes a compatibility guide by model pairing on totousa.com.

Is the TOTO UltraMax II ADA compliant?

Yes. The UltraMax II seat height is approximately 17.25 inches from finished floor to top of seat, meeting the ADA accessibility standard range of 17 to 19 inches. The Drake II at 16.5 inches also falls within ADA range on most configurations. Comfort-height TOTO models are beneficial for taller users and individuals with mobility limitations regardless of formal ADA requirements.

How long do TOTO toilets typically last?

The vitreous china bowl and tank of a TOTO toilet are designed to last 20 to 50 years under normal residential use conditions. Internal mechanical components -- fill valve, flapper, flush valve -- typically require replacement every 5 to 15 years depending on water quality and usage frequency. TOTO replacement parts are broadly stocked at plumbing supply houses and major hardware retailers, making maintenance straightforward and cost-effective throughout the toilet's life.

What colors does TOTO offer?

TOTO's three primary North American residential colors are Cotton White (#01), Colonial White (#11), and Sedona Beige (#12). Cotton White is the most widely available and is TOTO's default photography color. Colonial White is a warmer intermediate tone. Sedona Beige suits traditional bathroom color schemes. TOTO does not offer a Bone colorway equivalent, which is worth verifying when matching to existing Kohler or American Standard fixtures.

Does TOTO make toilets in the United States?

Yes. TOTO operates a manufacturing facility in Morrow, Georgia. Some North American products carry "Made in USA" labeling reflecting assembly there. Other TOTO products sold in the U.S. are manufactured in Japan or China. Country of origin for a specific model is disclosed on product packaging and on totousa.com by model number.

What is TOTO's warranty compared to Kohler and American Standard?

TOTO offers a one-year limited warranty on parts and a three-year limited warranty on vitreous china. Kohler provides a one-year limited warranty on most residential products. American Standard offers a limited lifetime warranty on china for some premium models. In practice, TOTO's broad parts availability at supply houses means out-of-warranty service is often faster and less expensive than for brands with limited parts distribution.

Which TOTO model is best for a high-traffic family bathroom?

For a high-traffic family bathroom with frequent heavy use, the TOTO UltraMax II is the top recommendation. Its 1,000-gram MaP score, Tornado Flush bowl scrubbing, CeFiONtect glaze, and one-piece design combine to minimize both clogging and cleaning frequency under heavy daily use. The Drake II is a close second at slightly lower cost if one-piece handling is a concern during installation.

Our Verdict

TOTO is the strongest all-around toilet brand in the North American residential market when evaluated on third-party MaP flush testing, surface glaze technology, manufacturing consistency, and long-term parts availability. The Drake II delivers the best value for most households: maximum 1,000-gram MaP performance at 1.28 GPF, CeFiONtect glaze, ADA comfort height, and broad serviceability. The UltraMax II is the upgrade path for buyers who want one-piece cleaning ease with equivalent flush performance. The Aquia IV is the right choice when water savings are the priority. At every tier, TOTO sets the documented performance standard that Kohler, American Standard, Gerber, and Woodbridge are usefully compared against -- and rarely exceeded on the metrics that matter most for daily use.
