The TOTO Vespin II is the toilet for buyers who want the clean, skirted look of a designer one-piece without giving up the easy handling and lower price of a two-piece. It pairs TOTO's quiet Double Cyclone flush with a fully concealed trapway, an elongated comfort-height bowl and an optional SanaGloss glaze, slotting between the plain, powerful TOTO Drake and the seamless TOTO UltraMax II. 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 Vespin II belongs in your bathroom.
Research updated June 2026.
The TOTO Vespin II is our top pick for buyers who want a fully skirted, easy-clean two-piece without paying one-piece prices. Its Double Cyclone flush earns an 800-gram MaP score on an efficient 1.28-gallon flush, the concealed trapway and optional SanaGloss glaze wipe clean fast, and the lighter separate parts make install easier than a fused one-piece. Note that the UltraMax II, which shares the same Double Cyclone system, actually posts a higher 1,000-gram MaP score in its own testing, so the Vespin II trades some flush headroom for its lighter, easier-to-carry two-piece body.
The TOTO Vespin II is what you get when TOTO takes the flush engineering and styling of its popular UltraMax II and rebuilds it as a two-piece. Where the original TOTO Drake is a plain, exposed-trapway workhorse that buyers tolerate for its raw power, the Vespin II hides the bulky waste passage behind a fully skirted base, smooths the exterior into a single clean sweep, and gives you the same quiet Double Cyclone flush. It is the toilet for people who want the modern, skirted look without the weight, awkward handling and higher cost of a fused one-piece, and TOTO has tuned it to deliver style, efficiency and a genuinely strong flush in one package.
This review looks past the showroom appeal and at the engineering and data that predict performance: the Vespin 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 Vespin 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 Vespin II alongside its toughest competition.
We do not install the Vespin II in a lab and flush it ourselves, and we will not pretend we do. Instead we read TOTO's published specifications, compare the Vespin 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 Vespin II is most commonly sold as the elongated, 1.28-gallon, skirted two-piece model MS484124CEFG (with the SanaGloss glaze), with non-glazed and finish variants carrying different suffixes. Because it is a two-piece, the tank and bowl ship as separate parts that bolt together on site, and TOTO designs the Vespin II to mount with a hidden bracket so the skirt sits flush to the floor. 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. The standard Vespin II is built for a 12-inch rough-in.
Flush quality is the reason TOTO toilets earn their reputation, and the Vespin 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, which is exactly the character buyers want in a styled bathroom.
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 Vespin 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 Vespin 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 skirted 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 Vespin II is the toilet we point people to when they love the clean skirted look of a one-piece but balk at the weight and price of a fused body. 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 two separate parts are far easier to carry up a flight of stairs. You give up a little raw power versus the Drake, but you gain a toilet that looks like a premium fixture and installs like an ordinary two-piece.
The Vespin II's biggest selling point is its body. The base is fully skirted, meaning a smooth ceramic panel wraps the sides and hides the bulky, exposed trapway you see bulging from the side of a Drake. The result looks almost identical to a one-piece from across the room, but because the tank and bowl remain separate components, you avoid the heavy single-unit lift of a fused toilet. For a bathroom where appearance matters as much as function, this is a meaningful upgrade, and the skirted exterior is the single feature owners praise most.
Most Vespin 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 smooth skirted base that has no exposed trapway to wipe around, the Vespin II is one of the easier two-piece toilets to maintain, which is why it appears in our roundup of the best skirted toilets.
The Vespin 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 Vespin 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 quietly using more water, the Vespin 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 Vespin II on MaP, both reaching 1000 grams. The Vespin II trades a small amount of that ceiling for a quieter, more refined flush and a skirted, easy-clean 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 Vespin 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 Vespin II handles the first with the Double Cyclone's focused twin-nozzle swirl, which builds a strong siphon, and the second with a fully 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 Vespin 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 fully skirted body keeps the footprint clean and modern.
On installation, the Vespin 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. The skirted design uses a special mounting bracket rather than the usual exposed floor bolts, so the installation is slightly different from a standard two-piece: you set the bracket, then lower the skirted bowl over it. This is straightforward but worth reading the TOTO instructions for, since it differs from a conventional bolt-down. The real advantage over a one-piece is weight: because the tank and bowl ship separately, each piece is lighter and easier to carry into a tight bathroom or up stairs. Owners with basic DIY confidence report a manageable setup, and because TOTO is so common, any plumber recognizes it instantly.
The Vespin II sits in a sensible spot on price-to-performance for its category. It costs more than a plain two-piece Drake because the skirted body and SanaGloss glaze cost more to produce, but it usually undercuts the seamless one-piece UltraMax II while matching it 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 Vespin II's 800 grams is squarely in the excellent band, so treat any toilet under 500 grams as a warning sign and the Vespin II as a confident pick.
The Vespin II is the toilet to buy when you want the clean, skirted look of a one-piece but the lighter parts and friendlier price of a two-piece, pairing TOTO's Double Cyclone system with a fully concealed trapway and 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 fully skirted base hides the exposed trapway, and the SanaGloss glaze keeps the surface slick and resistant to buildup.
Aggregated owner reviews highlight the clean modern look, the easy maintenance and the quiet, effective flush. The most common criticisms are the higher price than a plain Drake, the slightly different skirted mounting that requires reading the instructions, and the visible tank-to-bowl seam that a true one-piece avoids, all minor against the styling on offer.
This is the toilet we recommend when buyers want the UltraMax II look but lighter pieces on install day. It delivers TOTO flush quality in a skirted body that looks like a premium fixture, and the 800-gram MaP score is more than any normal household needs.
The UltraMax II is the one-piece version of the same idea, using the same Double Cyclone flush system as the Vespin II but reaching a higher, perfect 1,000-gram MaP score in a fully seamless body with no tank-to-bowl seam to scrub.
The UltraMax II uses the same Double Cyclone flush as the Vespin II but posts a higher 1,000-gram MaP rating, and its fused one-piece body removes the tank-to-bowl seam entirely, giving the cleanest possible exterior. The trade-off is weight: the bowl and tank arrive as a single heavy unit that benefits from a second pair of hands.
Owner reviews praise the UltraMax II for being one of the easiest toilets to keep clean, with no seam or gap to trap grime. Our TOTO Aquia IV review covers a dual-flush alternative if water saving is your priority over the seamless body.
Choose the UltraMax II over the Vespin II if a truly seamless body matters more than easy handling, and you get a genuine flush upgrade to the maximum 1,000-gram MaP score in the same styling as the Vespin II, at the cost of a heavier install.
The Drake is the harder-flushing, cheaper exposed-trapway sibling, trading the Vespin II's skirted 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 Vespin II, with an exposed trapway you must clean around, 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.
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 exposed trapway, and you get the strongest TOTO flush for less money.
Cleaning is where the Vespin II earns its keep. The fully skirted base wraps the exterior in a smooth ceramic panel, removing the bulky exposed trapway that you must scrub around on a Drake, so the outside wipes down in a single pass. Inside, the SanaGloss glaze keeps the bowl surface slick, and the Double Cyclone's two-nozzle rinse washes the walls thoroughly on every flush. The one honest caveat versus a one-piece is the tank-to-bowl seam, which still collects a little dust, but the skirted base more than makes up for it. Aggregated owner reviews repeatedly mention how easy the smooth exterior is to keep clean.
Noise is a quiet win for the Vespin 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 Vespin 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. Because the Vespin II is a two-piece, you retain the ability to service or swap the tank independently of the bowl, an advantage a fused one-piece does not offer. Owners report the Vespin II as a low-maintenance, dependable fixture over many years.
The Vespin II is the right call for homeowners who want a toilet that flushes strongly, resists clogs, saves water and looks like a sleek skirted fixture, all while installing with the lighter, separate parts of a two-piece. It suits standard 12-inch rough-in bathrooms, rewards buyers who value a smooth, 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 remodel where appearance matters but a heavy one-piece lift is unwelcome.
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 a truly seamless body with no tank-to-bowl seam. In those cases the cheaper, harder-flushing TOTO Drake, the seamless one-piece UltraMax II, or a refined Kohler Cimarron may serve you better.
When buyers describe wanting the styled, skirted look of the UltraMax II but with parts they can actually carry, the Vespin 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 read TOTO's bracket-mount instructions before you start since the skirted install differs from a standard bolt-down. 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.

The Vespin II also appears throughout our pillar guide to the best flushing toilets.
Yes. The Vespin II is one of the most recommended skirted two-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 concealed-trapway skirted body with optional SanaGloss glaze makes it easy to keep clean. Its higher price than a plain Drake is the main trade-off.
The TOTO Vespin 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 fully 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.
Both use the same Double Cyclone flush, but the UltraMax II earns a higher, maximum 1,000-gram MaP score versus the Vespin II's 800 grams. The UltraMax II is a seamless one-piece with no tank-to-bowl seam, while the Vespin II is a skirted two-piece with lighter, separate parts that are easier to carry. Choose the UltraMax II for the seamless body and the stronger flush score, and the Vespin II for easier handling and usually a lower price.
The Drake is a plain two-piece with an exposed trapway using the older, harder G-Max flush rated at a maximum 1000-gram MaP score, while the Vespin II is a fully skirted two-piece using the quieter Double Cyclone flush rated at 800 grams. The Vespin II looks cleaner and runs quieter; the Drake flushes harder and costs less.
The Vespin 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 Vespin 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 Vespin II meets both, which is notable given the strong 800-gram MaP score it achieves on 1.28 gallons.
A skirted trapway means a smooth ceramic panel wraps the sides of the toilet base and conceals the bulky waste passage that bulges from the side of a standard toilet like the Drake. This gives the Vespin II a clean, modern look almost identical to a one-piece, and it removes the awkward contours you normally have to clean around.
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 Vespin 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 Vespin II fits a standard 12-inch rough-in, the distance from the finished wall to the center of the floor drain, which covers most homes. Always confirm the rough-in on the listing before ordering, and note that the skirted design uses a mounting bracket rather than conventional exposed floor bolts.
Yes. The Vespin 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 Vespin 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.
The Vespin II installs like a two-piece with one difference: the skirted base mounts on a special bracket rather than standard exposed floor bolts, so you set the bracket first and lower the bowl over it. It is straightforward but worth reading the TOTO instructions for. The lighter separate parts make it easier to carry than a one-piece.
Many Vespin 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.
With normal use the Vespin II typically lasts many years, and the ceramic body itself can last for decades. TOTO flush and fill valves are widely available for repairs. As a two-piece, it also lets you service or swap the tank independently of the bowl, an advantage a fused one-piece does not offer.
The Vespin II is a single-flush skirted two-piece using the Double Cyclone system at 800 grams on MaP, while the Aquia IV is a dual-flush skirted model using the Tornado Flush that reaches a higher, perfect 1,000-gram MaP score on its full flush along with a water-saving half flush. Choose the Aquia IV if either the stronger flush score or dual-flush water saving matters to you, and the Vespin II if you prefer the simplicity of a single-flush lever.
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 model may fit better. Measure your available depth and confirm the model's footprint on the listing before ordering.
For buyers who want a skirted look, yes. It usually costs less than the seamless UltraMax II while delivering the same flush, the same SanaGloss option and lighter parts for install. If you care more about raw flush power or the lowest price, the plain Drake offers better value while looking less refined.
The TOTO Vespin II is the toilet we recommend first to buyers who want the clean, skirted look of a one-piece without the weight or the higher price. 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 fully skirted base hides the exposed trapway for an easy-wipe exterior. It runs quietly and looks like a premium fixture, while the separate tank and bowl carry far easier than a fused one-piece and let you service the tank independently. The trade-offs are a higher price than the plain Drake, a skirted bracket mount that differs from a standard bolt-down, and a visible tank-to-bowl seam that a true one-piece avoids. For a main or guest bathroom remodel where appearance and easy cleaning matter as much as power, it is one of the safest skirted picks on the market. If you want maximum flush force or the lowest price instead, the Drake is the move; if you want a truly seamless body, step up to the UltraMax II. Check the current price on Amazon to see where it sits today.
