The Woodbridge T-0001 is the model that put the brand on the map: a fully skirted, comfort-height, dual-flush one-piece that delivers a contemporary designer look at a price that undercuts TOTO and Kohler by a wide margin. It is Woodbridge's best-selling toilet, and it has built a large following on the strength of its clean seamless body, its included soft-close lid and its low-maintenance shape. This review compares the T-0001's published specifications, its dual-flush water use, its WaterSense eligibility, its certifications and the recurring themes across thousands of aggregated owner reviews, so you can decide whether this is the right toilet for your bathroom.
Research updated June 2026.
The Woodbridge T-0001 is our top pick for buyers who want a premium skirted one-piece look without premium pricing. Its dual-flush siphon clears waste cleanly on a 1.0/1.6-gallon split, the seamless body and quiet soft-close lid wipe clean in seconds, and the comfort height suits most adults. It is a very good rather than maximum flusher, so it shines in healthy-drain bathrooms.
The Woodbridge T-0001 sits at the head of a category that barely existed fifteen years ago: the affordable, modern, fully skirted one-piece toilet. For a long stretch, a smooth skirted profile and a seamless tank-to-bowl body meant paying premium money to TOTO or Kohler. Woodbridge built its reputation by delivering that contemporary look at a price most households can absorb, and the T-0001 is the model that did it. It is consistently the brand's best seller, the toilet people buy when a plain builder-grade two-piece simply will not match a refreshed bathroom.
This review looks past the showroom appeal and at the data that actually predicts how a toilet performs once it is bolted to the floor. We compare the T-0001's published specifications, its dual-flush water-use figures, its WaterSense eligibility and trapway design against rival toilets, and study the consistent patterns across thousands of aggregated owner reviews covering flushing, clog resistance, cleaning, noise and reliability. Where the T-0001 has real weaknesses, and it has a few, we name them plainly. To see how it stacks up against the wider field first, our pillar roundup of the best flushing toilets places the T-0001 alongside its toughest competition.
We do not install the T-0001 in a lab and flush it ourselves, and we will not pretend we do. Instead we read Woodbridge's published specifications, compare its dual-flush water-use figures and trapway design against rival toilets, factor in WaterSense eligibility 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 and MaP. Woodbridge sells several visually similar skirted one-pieces (the T-0001, the T-0019, the B-0750 and others) that share the same dual-flush platform but differ in lid style, finish and bowl height. Woodbridge does not always publish an official MaP (Maximum Performance) score for every SKU, so the 600 to 800 gram range shown reflects the typical performance of comparable 1.6-gallon dual-flush siphonic bowls rather than a single certified figure. Always confirm the rough-in, bowl shape, flush volumes and exact model number on the listing before you order, and treat the flush figure as a class estimate.
The T-0001 uses a dual-flush siphonic system, and that is the defining trait that shapes how the toilet behaves day to day. Two buttons sit on top of the tank: a partial flush rated around 1.0 gallon for liquid waste and a full flush rated at 1.6 gallons for solids. The full flush relies on a true siphon, meaning the bowl fills quickly and a column of water grabs the waste and pulls it down the trapway, rather than simply washing it over a ledge the way a cheaper washdown bowl does. A siphonic flush generally leaves a cleaner bowl, holds a larger standing water spot and keeps odors down between uses, which is a meaningful advantage over the basic washdown bowls some budget rivals ship.
On raw clearing power the T-0001 is a strong mid-pack performer rather than a clog-busting champion. Woodbridge does not publish an official MaP score for the model, so it cannot claim the verified 1000-gram ceiling that a TOTO Drake or American Standard Champion 4 reaches. Comparable 1.6-gallon dual-flush siphonic bowls typically grade in the 600 to 800 gram range in independent MaP testing, comfortably above the 350-gram weak-flush threshold and enough for the vast majority of households. Owner reviews back this up: most buyers report clean, reliable, single-flush clearing, while a small minority with heavy waste loads or older drain lines mention an occasional second flush.
Buy the T-0001 for the look, the seamless body and the included soft-close lid, not for maximum flush force. The dual-flush siphon is genuinely good for everyday use and keeps the bowl clean, but it is not the toilet we would point a chronic-clog household toward. If your old toilet clogged constantly no matter what you did, step up to a verified 1000-gram MaP model like the TOTO Drake. If your drains are healthy and you want a premium modern skirted body, the T-0001 flushes more than well enough.
The dual-flush design is the T-0001's efficiency story. The half flush uses roughly 1.0 gallon and the full flush uses 1.6 gallons, and in a typical home where most flushes are liquid, the effective average use falls well below the federal 1.6-gallon ceiling. That average is exactly the behavior the EPA WaterSense program is built to reward, and dual-flush toilets in this class are commonly WaterSense eligible when their certified average use meets the standard. Confirm the WaterSense mark on the specific listing you are buying, since eligibility can vary by SKU, finish and configuration of the same model line.
To be precise, the T-0001's full flush at 1.6 gallons is not the most aggressive water saver on paper, since many single-flush rivals run a flat 1.28 gallons and the Swiss Madison St. Tropez offers a lower 0.8/1.28 split. Where the T-0001 wins is the real-world average, because the partial flush handles most daily use cheaply. For households focused on water bills and utility rebates, the dual-flush math usually lands in its favor, and the T-0001 sits naturally alongside the models in our roundup of the best dual-flush toilets.
If raw clearing strength is your single priority, the T-0001 is not the toilet to chase. Verified 1000-gram performers like the TOTO Drake, with its wide 3-inch G-Max valve, and the American Standard Champion 4, with its enormous 4-inch valve, clear more waste per flush than any dual-flush one-piece in this price range. The T-0001's appeal is balance: a siphon strong enough for normal households, a clean premium body, a quiet soft-close lid and dual-flush savings. Buyers who need maximum force should compare the heavyweights in our pillar guide to the best flushing toilets before committing.
Clog resistance comes from two things working together: how much water arrives in the bowl at once, and how smoothly the trapway lets waste escape. The T-0001's siphonic full flush handles the first reasonably well, and its glazed trapway gives waste a slick path out. Where it falls short of the clog-busting elite is the absence of a verified high MaP score and the narrower internal passages typical of slim, designer one-pieces. For most homes it is perfectly fine, but buyers with a bathroom that clogs no matter what should read our guide to the toilets that never clog, where higher-MaP models lead.
Design is where the T-0001 truly earns its keep. It is a fully skirted one-piece, meaning the sides of the bowl sweep down in a smooth, continuous surface that hides the trapway and bolts entirely. There is no exposed S-bend on the side, no two-piece seam between tank and bowl, and far fewer crevices for dust and grime to collect in. Cleaning is genuinely fast: a single wipe down the smooth skirt and you are done, with none of the awkward scrubbing around an exposed trapway that a plain two-piece demands. Owners consistently single out the easy cleaning and the upscale appearance as the top reasons they would buy it again.
The styling is contemporary and low-profile, with soft modern lines that suit current vanities far better than a utilitarian builder toilet. As the flagship of the line, the T-0001 ships with a premium soft-close, quick-release seat and lid that lifts off for cleaning, a feature that costs extra on many rivals and one that owners rate as noticeably quieter and better finished than the budget seats on cheaper toilets. It comes in white as standard, with other finishes on some listings. For buyers who want this seamless, easy-clean profile, we compare bodies the same way in our roundup of the best flushing one-piece toilets, where Woodbridge is a recurring value pick.
The T-0001 is a comfort-height (chair-height) toilet, with the seat sitting around 17 to 18 inches from the floor including the seat. That taller stance is easier on the knees and back than a standard 15-inch toilet, which is why owners with mobility concerns and taller users favor it. It uses an elongated bowl, giving more seating room than a round front at the cost of a slightly larger footprint to measure against your space. Buyers who want this stance across brands can compare options in our guide to the best comfort-height toilets.
On noise, the dual-flush siphon is moderate. Owner reviews describe the full flush as a normal, brief rush of water, quieter than a pressure-assisted toilet and comparable to other gravity-fed one-pieces. The partial flush is quieter still, and the premium soft-close lid means no slamming. A few owners mention the fill valve being audible as the tank refills, a common budget-tier trait usually solved with an inexpensive replacement valve. For bathrooms near bedrooms the T-0001 is acceptable, though it is not the single quietest choice on the market.
The T-0001 fits the standard 12-inch rough-in (the distance from the finished wall to the center of the floor drain) that covers most homes. As a one-piece, it arrives as a single heavy ceramic unit, which makes for a clean, seam-free result but a heavier carry, so plan for a second pair of hands during installation. Most listings include the wax ring, mounting bolts and the soft-close seat, so the box is reasonably complete, and owners with basic DIY confidence routinely report a straightforward install on a standard layout.
On reliability, the picture is mostly positive with honest caveats. The ceramic body and glazing earn consistent praise, and the brand backs the toilet with a multi-year limited warranty on the porcelain. The most common owner criticisms cluster around the internal flush mechanics rather than the body: a small share mention the dual-flush button assembly or the fill valve needing adjustment over time. Because Woodbridge uses fairly standard internal components, these are usually low-cost, widely available fixes rather than reasons to replace the toilet. Check the current price on Amazon to see where it lands today.
The T-0001 sits in a smart spot on price-to-features. It costs more than a bare builder-grade two-piece but delivers a fully skirted one-piece body, comfort height and a premium soft-close lid that, on TOTO or Kohler, would push the total far higher. Against the TOTO UltraMax II and Kohler Santa Rosa it gives up some verified flush power and brand pedigree, but it undercuts them while matching them on looks and seat quality. For a remodel-grade appearance on a real budget, that value is why the T-0001 keeps 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 brand-neutral protocol. Many older low-flow toilets graded under 350 grams, which is where the reputation for weak flushing began. Modern high-efficiency toilets routinely clear 600 grams or more, and the best, like the TOTO Drake, hit the 1000-gram ceiling. When you shop, treat a score under 500 grams as a warning sign, 600 to 800 grams as a solid everyday performer (where the T-0001 class sits), and 800 or more as a confident pick for problem bathrooms.
The T-0001 is the toilet to buy when you want Woodbridge's best-selling skirted one-piece, pairing a competent dual-flush siphon with a quiet, premium soft-close lid and a seamless easy-clean body on a real budget.
The dual-flush siphonic system pairs a 1.0-gallon partial flush with a 1.6-gallon full flush, holding a generous water spot that keeps the bowl clean between uses. It is a competent everyday flusher, though Woodbridge publishes no official MaP score, so it cannot claim the verified 1000-gram ceiling of the strongest gravity rivals.
Owner reviews lean strongly positive on looks, easy cleaning and the included premium soft-close lid, with most buyers reporting reliable single-flush clearing. The common criticisms involve the dual-flush button or fill valve occasionally needing adjustment, both inexpensive standard fixes rather than body failures.
This is the value pick we point remodelers to most often when they want the premium skirted one-piece look without the premium price. Accept that it is a good rather than great flusher, confirm your drains are healthy, and the T-0001 delivers a modern, easy-clean toilet with a genuinely nice lid that punches well above its cost.
The T-0019 shares the T-0001's dual-flush platform in a slightly different skirted body, usually at a lower price, making it the natural cross-shop for buyers who want the Woodbridge formula for a little less.
The T-0019 uses the same dual-flush siphon as the T-0001 but in a slightly different skirted body, usually at a lower price. The flush behavior and water-use figures are effectively the same, so the choice comes down to styling, lid finish and the price each model shows on the day you shop.
Owner reviews praise the T-0019 for the same clean look and easy cleaning, with the same minor caveats about the dual-flush mechanism over time. If the T-0001 flagship and the T-0019 are priced close together, buy the body and lid you prefer, since they are the same toilet underneath.
If you like the Woodbridge formula and the T-0019 is meaningfully cheaper than the T-0001 on the day you shop, the savings are real and the flush is the same. Let price and which body you prefer decide between these two siblings.
The UltraMax II is the premium one-piece to step up to when you want a verified flush score and long-term TOTO reliability in a seamless body.
The UltraMax II uses TOTO's Double Cyclone flush, rinsing the bowl with two nozzles instead of conventional rim holes and earning a verified 800-gram MaP score on a flat 1.28-gallon flush. The seamless body and optional SanaGloss glaze make it easy to keep clean.
Owner reviews are among the strongest of any one-piece, praising the quiet, reliable flush and TOTO's parts support. The trade-offs are a higher price and no dual-flush button, but for proven performance the UltraMax II is the safe step up from the T-0001.
Choose the UltraMax II over the T-0001 when verified flush power and brand reliability matter more than upfront cost. It is the toilet we recommend when a buyer wants a one-piece they will never have to think about again.
The T-0001 is the right call for homeowners and remodelers who want a modern, fully skirted one-piece with comfort height, dual-flush efficiency and a quiet premium soft-close lid at a budget brands like TOTO and Kohler cannot match. It suits standard 12-inch rough-in bathrooms with healthy drain lines, rewards buyers who care about clean styling and fast cleaning, and is a smart pick for primary baths, guest baths and powder rooms where looks and easy maintenance matter most.
You should look elsewhere if your bathroom clogs constantly or you want the strongest possible flush. In those cases a verified 1000-gram model like the TOTO Drake, or the proven 800-gram UltraMax II, will serve you better. Buyers wanting an even lower entry price with a similar modern look can consider the Swiss Madison St. Tropez, while those wanting maximum brand reliability should weigh the Kohler Santa Rosa. And if the near-identical T-0019 is priced lower on the day you shop, it is the same toilet underneath.
When a buyer is remodeling and wants the seamless designer skirted look without designer pricing, the T-0001 is the model we recommend most often. Match the rough-in to your space, confirm your drains are healthy since this is a good rather than maximum flusher, and the T-0001's combination of a clean modern body, dual-flush efficiency and a genuinely nice soft-close lid delivers real value. Accept the unpublished MaP figure and the occasional dual-flush adjustment, and you get a remodel-grade toilet at a fraction of the designer cost.
A verified 1000-gram MaP score from a wide 3-inch G-Max valve, on an efficient 1.28 gallons. The toilet to choose if your bathroom clogs constantly, though it is a plainer two-piece without the T-0001's skirted look.

Yes, for the right buyer. The T-0001 is Woodbridge's best-selling, strong-value modern skirted one-piece with a competent dual-flush siphon, comfort height and a quiet premium soft-close lid. It is a good rather than maximum flusher, so it suits healthy-drain bathrooms where looks, easy cleaning and price matter more than raw clog-busting power.
It is a strong mid-range flush. The dual-flush siphonic system clears waste cleanly on a 1.6-gallon full flush, and comparable bowls of this type typically grade in the 600 to 800 gram range in independent MaP testing. It is plenty for most homes but below the verified 1000-gram performers like the TOTO Drake.
Woodbridge does not publish an official MaP (Maximum Performance) score for the T-0001, so there is no single certified figure. Based on comparable 1.6-gallon dual-flush siphonic bowls, it falls in the solid 600 to 800 gram range. Treat that as a class estimate rather than a verified rating, and confirm on the listing.
Not for most households. The siphonic full flush and glazed trapway give waste a clean path out, and most owner reviews report reliable flushing. A minority with heavy waste or older drain lines mention occasional second flushes. For a chronically problematic bathroom, a verified high-MaP toilet is the safer pick.
It uses a dual-flush system: roughly 1.0 gallon for the partial (liquid) flush and 1.6 gallons for the full (solid) flush. Because most daily flushes are partial, the real-world average use is well below 1.6 gallons, which is the efficiency advantage of a dual-flush design.
Dual-flush toilets in this class are commonly WaterSense eligible when their certified average use meets the EPA standard, but certification varies by SKU. Confirm the WaterSense mark on the specific listing you are buying, since finishes and configurations of the same model can differ.
It is a fully skirted one-piece toilet. The tank and bowl are a single seamless ceramic unit, and the sides sweep down smoothly to hide the trapway and bolts. This gives a clean modern look and makes cleaning fast, with none of the seams or exposed trapway of a two-piece toilet.
It is a comfort-height (chair-height) toilet, with the seat sitting around 17 to 18 inches from the floor including the seat. That taller stance is easier on the knees and back than a standard 15-inch toilet and suits most adults and taller users comfortably.
Yes. Most T-0001 listings include a premium soft-close, quick-release seat and lid that lifts off for cleaning, which is a feature that costs extra on many competing toilets. Confirm the seat is included on the specific listing, since bundles occasionally vary.
The T-0001 fits a standard 12-inch rough-in, the distance from the finished wall to the center of the floor drain, which covers the large majority of homes. Measure your rough-in before ordering, since a 10 or 14-inch layout would require a different toilet.
The T-0001 uses an elongated bowl, which offers more seating room than a round front at the cost of a slightly larger footprint. Measure the available space in front of the toilet before ordering to be sure the elongated shape fits your bathroom.
No, most owners report a straightforward install. It is a one-piece, so it arrives as a single heavy ceramic unit that needs two people to carry safely, but most listings include the wax ring, bolts and seat. Basic DIY confidence is enough for a standard 12-inch rough-in.
The flush noise is moderate. The full siphonic flush is a normal, brief rush of water, quieter than any pressure-assisted toilet and comparable to other gravity one-pieces. The premium soft-close lid means no slamming, though a few owners note an audible fill valve, which a low-cost replacement resolves.
The ceramic body typically lasts many years and is backed by a multi-year limited warranty. The parts most likely to need attention over time are the dual-flush button assembly and the fill valve, both inexpensive, widely available components rather than body failures, which keeps long-term ownership affordable.
Both share the same dual-flush siphon platform and water-use figures, so the flush behavior is effectively identical. The differences are cosmetic: the T-0001 is Woodbridge's best-selling flagship body with a slightly more premium lid, and the T-0019 is a near-identical sibling that often costs a little less. Choose by looks and price.
The UltraMax II is the stronger, more proven toilet, with a verified 800-gram MaP score and TOTO reliability, but it costs more and is single flush. The T-0001 wins on price and dual-flush savings while matching the modern look. Choose the T-0001 for value and the UltraMax II for verified power.
Yes, it is well suited to guest baths and powder rooms. The clean skirted look, comfort height and fast, easy cleaning make a strong impression, and the dual-flush efficiency suits a room that sees lighter use. Its good everyday flush is more than adequate for typical guest-bath demands.
The T-0001 is consistently Woodbridge's best seller because it bundles a seamless designer skirted body, comfort height, a quiet premium soft-close lid and dual-flush efficiency at a price that undercuts comparable TOTO and Kohler one-pieces. That mix of looks, easy cleaning and value drives its strong, repeat-buyer following.
For buyers prioritizing modern looks, easy cleaning, a quiet premium lid and dual-flush efficiency, yes. It bundles a skirted one-piece body, comfort height and a soft-close seat at a price premium brands cannot match. If your priority is maximum verified flush power for a clog-prone bathroom, a higher-MaP toilet may be the smarter spend.
The Woodbridge T-0001 is the toilet we recommend first to remodelers who want a designer skirted one-piece look without designer pricing, and its best-seller status is well earned. Its dual-flush siphon clears waste cleanly on a 1.0/1.6-gallon split, the fully skirted body wipes clean in seconds, and the comfort height plus a quiet premium soft-close lid round out a strong feature bundle. It is a good rather than maximum flusher, with no published MaP score and an occasional dual-flush adjustment to plan for, so it is best matched to healthy-drain bathrooms rather than chronically clog-prone ones. If you need verified maximum power instead, the TOTO Drake or UltraMax II are the step up, and if the near-identical T-0019 is cheaper on the day you shop, it is the same toilet underneath.
