The TOTO UltraMax II is the toilet for buyers who want TOTO's clog-resistant flush wrapped in a sleek, seamless one-piece body that is far easier to keep clean. It pairs the Double Cyclone flush with an optional SanaGloss ceramic glaze and a comfort-height bowl, landing squarely between the plain, powerful Drake and a designer one-piece. This review compares its published specifications, independent MaP flush-test score, water use, WaterSense certification and the recurring themes across aggregated owner reviews, so you can decide whether the UltraMax II belongs in your bathroom.
Research updated June 2026.
The TOTO UltraMax II is our top pick for buyers who want a seamless, easy-clean one-piece without giving up real flush power. Its Double Cyclone flush earns an 800-gram MaP score on an efficient 1.28-gallon flush, the optional SanaGloss glaze resists buildup, and the one-piece body has no tank-to-bowl seam to scrub. It costs more than the Drake, but it cleans and looks like a premium toilet.
The TOTO UltraMax II is what happens when you take the flush engineering that made TOTO famous and pour it into a body that actually looks good in a modern bathroom. Where the legendary TOTO Drake is a plain, exposed-trapway two-piece that buyers tolerate for its power, the UltraMax II is a low-profile, skirted one-piece designed to be wiped clean in seconds and to sit handsomely against the wall. It is the toilet for people who refuse to choose between a strong flush and a clean look, and TOTO has tuned it to deliver a good measure of both.
This review looks past the showroom appeal and at the engineering and data that predict performance: the UltraMax II's published specifications, its independent MaP (Maximum Performance) flush-test score against rivals graded by the identical protocol, its WaterSense certification and gallons-per-flush figure, and the consistent patterns across thousands of aggregated owner reviews on clogging, cleaning, noise and reliability. Where the UltraMax II has real weaknesses, we name them. To see how it stacks up against the wider field first, our pillar roundup of the best flushing toilets places the UltraMax II alongside its toughest competition.
We do not install the UltraMax II in a lab and flush it ourselves, and we will not pretend we do. Instead we read TOTO's published specifications, compare the UltraMax II's independent MaP flush-test score against rival toilets graded by the same identical protocol, factor in WaterSense certification and gallons per flush to reward power that stays efficient, and study the recurring themes across thousands of aggregated owner reviews. No payment buys a favorable verdict on this page.

A note on model codes. The UltraMax II is most commonly sold as the elongated, 1.28-gallon, one-piece model MS604114CEFG (with the SanaGloss glaze) or MS604114CEFG in related finishes, with non-glazed variants carrying different suffixes. There is also a 10-inch rough-in version and a taller universal-height bowl. Spec figures and the exact MaP score vary slightly by SKU and finish, so always confirm the rough-in, bowl height and SanaGloss option on the listing before you order. Because it is a one-piece, the bowl and tank arrive fused as a single unit, so there is no separate combo to pair.
Flush quality is the reason TOTO toilets earn their reputation, and the UltraMax II is built around the Double Cyclone system rather than the older G-Max found on the original Drake. Instead of dozens of small rim holes, the Double Cyclone uses two powerful nozzles positioned at the back of the rim. These nozzles direct water around the bowl in a centrifugal, swirling motion that both rinses the bowl walls more thoroughly and channels force into the siphon that pulls waste down the trapway. The result is a flush that is strong, clean and noticeably quieter than the brute G-Max rush.
In independent MaP testing, which measures how many grams of solid waste a toilet clears in a single flush under an identical protocol across every brand, the UltraMax II earns an 800-gram rating. That is excellent: the MaP program considers anything above 600 grams strong real-world performance, and 800 grams puts the UltraMax II comfortably in clog-resistant territory. It sits a step below the original Drake's maximum 1000-gram score, which is the honest trade you make for the quieter, refined Double Cyclone flush and the seamless body. In owner reviews the practical result is reassuring: reports of clogs and double flushing are uncommon, and households moving from a weak low-flow toilet describe a clear upgrade in clearing power.
The UltraMax II is the toilet we point people to when they want TOTO flush quality but cannot stomach the Drake's plain, exposed-trapway looks. The 800-gram MaP score is more than enough for a typical household, the Double Cyclone flush is quieter and rinses the bowl beautifully, and the seamless one-piece body is genuinely easier to live with. You give up a little raw power versus the Drake, but you gain a toilet that looks and cleans like a premium fixture.
The UltraMax II's biggest selling point is its body. As a one-piece, the tank and bowl are fused into a single seamless ceramic unit, which removes the gap and bolt seam where a two-piece toilet collects dust, grime and stray hair. The profile is low and modern, with a partially concealed trapway that hides the bulky exposed waste passage you see on the side of a Drake. For a bathroom where appearance matters as much as function, this is a meaningful upgrade, and it is the single feature owners praise most.
Most UltraMax II configurations include TOTO's SanaGloss (CeFiONtect) glaze, an ultra-smooth, ion-barrier ceramic coating that makes it harder for mold, mildew and waste particles to cling to the bowl. In practice owners report that the bowl stays cleaner between scrubbings and needs less aggressive chemical cleaning, though SanaGloss is not a substitute for cleaning entirely. Combined with the seamless body, the UltraMax II is one of the easier toilets to maintain, which is why it appears in our roundup of the best flushing one-piece toilets.
The UltraMax II uses 1.28 gallons per flush and carries WaterSense certification, which means it meets the EPA program's standard for using at least 20 percent less water than the federal 1.6-gallon maximum while still passing flush-performance criteria. Earning an 800-gram MaP score on that reduced volume is genuinely efficient engineering: the Double Cyclone system is designed to do more with each drop, channeling the limited water into a focused swirl rather than a wasteful flood.
Over a year of normal household use, that lower volume adds up to a meaningful water saving, and in regions that offer toilet rebates a WaterSense model can qualify. The UltraMax II is one of the toilets we point to in our roundup of the best EPA WaterSense toilets, where its blend of efficiency and real flush power is exactly the balance the certification is meant to reward. Unlike some single-flush toilets that hit their MaP score only by using more water, the UltraMax II keeps both the efficiency and the performance in the same package.
If raw clearing force is your single highest priority, the Drake and the American Standard Champion 4 sit above the UltraMax II on MaP, both reaching 1000 grams. The UltraMax II trades a small amount of that ceiling for a quieter, more refined flush and a one-piece body. For an even stronger push than any gravity toilet provides, a pressure-assisted unit using a Flushmate tank moves water faster and louder, which we cover in our guide to the best pressure-assisted toilets. For the great majority of homes, though, the UltraMax II's 800-gram flush clears everything it needs to on the first try.
Clog resistance comes from two things working together: how much water arrives in the bowl at once, and how smoothly that water and waste can escape. The UltraMax II handles the first with the Double Cyclone's focused twin-nozzle swirl, which builds a strong siphon, and the second with a glazed trapway that resists the streaking and snagging that cause partial clogs. The SanaGloss coating helps too, keeping the bowl surface slick so waste has less to cling to. Buyers dealing with a chronically problematic bathroom should also read our guide to the toilets that never clog, where higher-MaP TOTO models lead the recommendations.
The UltraMax II uses TOTO's Universal Height bowl, which sits at roughly 17-1/4 inches to the rim before the seat. This comfort-friendly height meets ADA seating guidance and is easier on the knees and back than a standard low toilet, which owners with mobility concerns and taller users frequently single out as a benefit. The elongated bowl shape offers more room than a round front, and the partially skirted body keeps the footprint clean.
On installation, the UltraMax II fits the standard 12-inch rough-in (the distance from the finished wall to the center of the floor drain) that covers most homes, with a 10-inch rough-in version available for older or unusual layouts. The honest trade-off of any one-piece is weight: because the tank and bowl are fused, the UltraMax II is heavier and more awkward to carry than a two-piece, where each part comes separately. Plan for a second pair of hands on install day. Owners with basic DIY confidence still report a straightforward setup once the unit is in place, and because TOTO is so common, any plumber recognizes it instantly.
The UltraMax II sits in a sensible spot on price-to-performance for its category. It costs more than a two-piece Drake because a fused one-piece body and SanaGloss glaze cost more to produce, but it undercuts many designer one-pieces while matching or beating them on flush data and reliability. For buyers who want a toilet that looks premium, cleans easily and still clears waste dependably for a decade, the value case holds, which is why TOTO models keep appearing in our roundup of the best flushing toilet for the money.
The MaP (Maximum Performance) test measures how many grams of soybean-paste test media a toilet removes in a single flush under a standardized protocol, giving a brand-neutral way to compare flush strength. Many older low-flow toilets graded poorly, sometimes under 350 grams, which is where the reputation for weak flushing began. Modern high-efficiency toilets routinely exceed 600 grams, and the best, like the TOTO Drake, hit the 1000-gram ceiling. The UltraMax II's 800 grams is squarely in the excellent band, so treat any toilet under 500 grams as a warning sign and the UltraMax II as a confident pick.
The UltraMax II is the toilet to buy when you want a strong, quiet flush in a seamless one-piece body that wipes clean in seconds, pairing TOTO's Double Cyclone system with the SanaGloss glaze.
The Double Cyclone flush uses two nozzles instead of conventional rim holes to create a centrifugal rinsing action, which cleans the bowl thoroughly and runs noticeably quieter than the original Drake's G-Max while still earning an 800-gram MaP score. The fused one-piece body removes the tank-to-bowl seam, and the SanaGloss glaze keeps the surface slick and resistant to buildup.
Aggregated owner reviews highlight the clean look, the easy maintenance and the quiet, effective flush. The most common criticisms are the higher price, the heavier single-piece install that benefits from a second person, and the slightly lower flush ceiling than the Drake, all minor against the refinement on offer.
This is the one-piece we would put in our own main bathroom. It delivers TOTO flush quality in a body that looks and cleans like a premium toilet, and the 800-gram MaP score is more than any normal household needs.
The Drake is the harder-flushing, cheaper two-piece sibling, trading the UltraMax II's seamless looks and quiet flush for a maximum 1000-gram MaP score.
The G-Max system pairs a wide 3-inch flush valve with a fully glazed 2-1/8 inch trapway, the formula behind its maximum 1000-gram MaP score. It is louder and plainer than the UltraMax II, with an exposed trapway, but it clears waste with more brute force and costs less.
Aggregated owner reviews for the Drake are among the most consistently positive of any toilet, with repeated praise for first-flush clearing. Our TOTO Drake review breaks down its flush power and specs in full, and our TOTO Drake vs UltraMax II comparison explains who each one suits.
If a problem bathroom that clogs no matter what is your situation, step down to the Drake for its 1000-gram flush. Accept the plain looks and modest noise, and you get the strongest TOTO flush for less money.
The Vespin II offers the UltraMax II's Double Cyclone flush in a fully skirted two-piece body that is easier to carry than a one-piece while still looking sleek.
The Vespin II uses the same Double Cyclone flush and 800-gram MaP rating as the UltraMax II, but its concealed-trapway skirted two-piece body means the tank and bowl ship separately, so each piece is lighter to carry into a tight bathroom.
Owner reviews praise the Vespin II for combining a modern skirted look with the easier handling of a two-piece. The main trade-off versus the UltraMax II is the visible tank-to-bowl seam, which a one-piece avoids entirely.
Choose the Vespin II if you love the skirted, easy-clean look but want lighter pieces on install day. It is the UltraMax II's flush in a more carryable body.
Cleaning is where the UltraMax II earns its keep. The seamless one-piece body has no tank-to-bowl seam or hardware gap to trap grime, and the partially concealed trapway smooths the exterior so there is far less to wipe than on an exposed-trapway Drake. Inside, the SanaGloss glaze keeps the bowl surface slick, and the Double Cyclone's two-nozzle rinse washes the walls thoroughly on every flush. Aggregated owner reviews repeatedly mention that the bowl stays cleaner between scrubbings and that the smooth exterior is a relief to maintain.
Noise is a quiet win for the UltraMax II. The Double Cyclone flush runs noticeably softer than the original Drake's G-Max rush and is far quieter than any pressure-assisted toilet, which makes it a sensible choice for a bathroom near a bedroom. Buyers chasing the absolute quietest flush can compare alternatives in our guide to quiet flush toilets, but the UltraMax II already sits on the calm end of the gravity-flush spectrum.
On reliability, TOTO's reputation is a real factor. The brand uses its own widely available flush-valve and fill-valve designs, and the ceramic body itself can last for decades. The one consideration unique to a one-piece is that you cannot swap the tank independently the way you can on a two-piece, though such failures are rare. Owners report the UltraMax II as a low-maintenance, dependable fixture over many years.
The UltraMax II is the right call for homeowners who want a toilet that flushes strongly, resists clogs, saves water and looks and cleans like a premium fixture. It suits standard 12-inch rough-in bathrooms (with a 10-inch option for awkward layouts), rewards buyers who value a seamless, easy-clean body and a quieter flush, and offers genuine peace of mind through TOTO's proven track record. It is an especially smart pick for a main or guest bathroom where appearance matters.
You should look elsewhere if budget is your top priority, if you need the absolute maximum 1000-gram flush for a chronically clog-prone bathroom, or if you want the lightest possible install. In those cases the cheaper, harder-flushing TOTO Drake, the dual-flush TOTO Aquia IV, or a refined Kohler Cimarron may serve you better.
When buyers describe wanting TOTO flush quality without the Drake's plain, exposed-trapway looks, the UltraMax II is the model we recommend first. Match the rough-in and bowl height to your space, confirm the SanaGloss option on the listing, and line up a second pair of hands for the heavier one-piece install. The Double Cyclone flush, glazed trapway and 800-gram MaP score then do the rest, giving you a toilet that looks premium, cleans easily and works quietly for a decade.

Yes. The UltraMax II is one of the most recommended one-piece toilets among owners and plumbers. Its Double Cyclone flush earns a strong 800-gram MaP score on an efficient 1.28 gallons, it carries WaterSense certification, and the seamless body with optional SanaGloss glaze makes it easy to keep clean. Its higher price and heavier install are the main trade-offs.
The TOTO UltraMax II earns an 800-gram rating in independent MaP (Maximum Performance) testing. That sits in the excellent band, since the program considers anything above 600 grams strong and 800 to 1000 grams near clog-proof. It is a step below the original Drake's maximum 1000-gram score but more than enough for most households.
No, clogging is uncommon. The Double Cyclone flush builds a strong centrifugal siphon, the glazed trapway gives waste a slick path out, and the SanaGloss coating keeps the bowl surface smooth. Aggregated owner reviews report few clogs. For an even higher clog-resistance ceiling, the TOTO Drake's 1000-gram flush is the stronger choice.
The Drake is a plain two-piece using the older, harder G-Max flush with a maximum 1000-gram MaP score, while the UltraMax II is a seamless one-piece using the quieter Double Cyclone flush rated at 800 grams. The UltraMax II looks and cleans better and runs quieter; the Drake flushes harder and costs less.
The UltraMax II uses 1.28 gallons per flush and is WaterSense certified, meaning it uses at least 20 percent less water than the federal 1.6-gallon maximum. Earning its 800-gram MaP score on that reduced volume reflects the efficiency of the Double Cyclone system, which focuses water into a swirl rather than a wasteful flood.
Yes, the UltraMax II is WaterSense certified. The EPA WaterSense program certifies toilets that use at least 20 percent less water than the federal maximum while still passing flush-performance criteria. The UltraMax II meets both, which is notable given the strong 800-gram MaP score it achieves on 1.28 gallons.
SanaGloss (also called CeFiONtect) is TOTO's ultra-smooth ceramic glaze that creates an ion barrier on the bowl surface, making it harder for mold, mildew and waste particles to cling. In practice the bowl stays cleaner between scrubbings, though it does not replace cleaning entirely. Most UltraMax II configurations include it.
No, it is on the quieter end for a gravity toilet. The Double Cyclone flush produces a softer, swirling rush of water rather than the brute roar of the original Drake's G-Max, and it is far quieter than any pressure-assisted toilet. This makes it a sensible choice for a bathroom near a bedroom.
The standard UltraMax II fits a 12-inch rough-in, the distance from the finished wall to the center of the floor drain, which covers most homes. A 10-inch rough-in version is also available for older or unusual layouts. Always confirm the rough-in on the listing before ordering.
Yes. The UltraMax II uses TOTO's Universal Height bowl, which sits at about 17-1/4 inches to the rim before the seat. This meets ADA seating guidance and is easier on the knees and back than a standard low toilet, which taller users and those with mobility concerns frequently appreciate.
The UltraMax II is sold with an elongated bowl, which offers more seating room than a round front. The elongated shape is the standard configuration for this model, so confirm the bowl shape and overall footprint on the listing to ensure it fits your bathroom before ordering.
Many UltraMax II listings include a TOTO SoftClose seat, but not all do, so always check the specific product page. Confirm the seat, the SanaGloss option and the rough-in at the same time so you receive the exact configuration you expect.
The install itself is standard, but the one-piece body is heavy and awkward to carry because the tank and bowl are fused, so a second pair of hands is recommended. Once positioned, owners with basic DIY confidence report a straightforward setup on a standard 12-inch rough-in.
With normal use the UltraMax II typically lasts many years, and the ceramic body itself can last for decades. TOTO flush and fill valves are widely available for repairs. The one consideration unique to a one-piece is that you cannot swap the tank independently, though serious internal failures are rare.
Both use the Double Cyclone flush and earn similar MaP scores. The Drake II is a two-piece with lighter, separate parts and a usually lower price, while the UltraMax II is a seamless one-piece that looks cleaner and has no tank-to-bowl seam. Choose the UltraMax II for the seamless body and the Drake II for easier handling and value.
It works in many bathrooms but has an elongated bowl, which takes more depth than a round front. If space is very tight, a compact one-piece like the Kohler Santa Rosa may fit better. Measure your available depth and confirm the model's footprint on the listing before ordering.
For buyers who want a premium one-piece, yes. It costs more than a two-piece Drake, but it delivers a seamless, easy-clean body, SanaGloss glaze, a quiet flush and proven reliability. If you care more about raw flush power or the lowest price, the Drake offers better value while looking plainer.
The TOTO UltraMax II is the toilet we recommend first to buyers who want TOTO flush quality without the Drake's plain looks. Its Double Cyclone flush earns a strong 800-gram MaP score on an efficient, WaterSense-certified 1.28 gallons, the optional SanaGloss glaze keeps the bowl clean, and the seamless one-piece body has no tank-to-bowl seam to scrub. It runs quietly and looks like a premium fixture. The trade-offs are a higher price than the Drake, a heavier install that benefits from a second person, and a flush ceiling a step below the Drake's maximum 1000 grams. For a main or guest bathroom where appearance and easy cleaning matter as much as power, it is one of the safest one-piece picks on the market. If you want maximum flush force or the lowest price instead, the Drake is the move. Check the current price on Amazon to see where it sits today.
