We evaluated packages from TOTO, Kohler, American Standard, Woodbridge, Swiss Madison, and Gerber using published MaP flush scores, EPA WaterSense certification data, and aggregated owner feedback.

Why Trust Best Flushing Toilets

  • Flushing power and MaP flush-test scores
  • Water efficiency (GPF and EPA WaterSense)
  • Aggregated owner reviews
  • Clog resistance and trapway design
  • Brand reliability and warranty

Research updated June 2026.

Quick Answer

The TOTO Drake II with SoftClose seat is the strongest complete package for most homeowners, earning a 1,000-gram MaP score and EPA WaterSense certification at 1.28 GPF. The American Standard Champion 4 Complete is the top pick if clog resistance is the primary concern, with its 2-3/8-inch fully glazed trapway and 4-inch accelerator flush valve.

What Is a Complete Toilet Package and Why Does It Matter?

A complete toilet package includes the toilet bowl, tank, and toilet seat sold together as one confirmed-compatible unit. This eliminates seat fit guesswork (elongated vs. round dimensions, hinge hole spacing, color matching), ensures the seat finish matches the toilet porcelain, and typically costs less than purchasing components separately.

Seat-to-bowl compatibility is a real problem in the market. Hinge hole spacing varies by manufacturer, and color names like "Cotton White," "Biscuit," and "Bone" differ meaningfully between brands. A package removes all of those variables at once.

TOTO Drake II Two-Piece Elongated 1.28 GPF Complete Package

4.7 Best For: Most homeowners wanting top MaP score with water savings

The Drake II package combines TOTO's E-MAX Double Cyclone flush system with a double-sized siphon jet, achieving a certified 1,000-gram MaP score while using just 1.28 GPF, making it one of the few packages that genuinely excels at both power and efficiency.

Flush Score (MaP)1,000 g
Water Use1.28 GPF
WaterSenseCertified
Seat TypeSoftClose
Rough-In12" (10"/14" available)
Pros
  • Maximum 1,000-gram MaP flush rating
  • EPA WaterSense certified at 1.28 GPF
  • CEFIONTECT ceramic glaze resists buildup
  • SoftClose seat with quick-release hinges
  • Available in three rough-in sizes
Cons
  • Higher price than budget two-piece packages
  • Two-piece design requires careful seating of tank gasket during install

The Drake II uses TOTO's Double Cyclone flushing technology, which routes water through two nozzles set at opposing angles to create a wide, turbulent swirl across the entire bowl surface. This mechanical action cleans more of the bowl wall per flush compared to rim-hole designs, explaining why it consistently earns full 1,000-gram MaP scores despite using 20% less water than 1.6-GPF toilets. CEFIONTECT glazing -- a titanium-oxide coating baked into the porcelain -- produces a surface so smooth that waste and mineral deposits have minimal adhesion points, reducing cleaning frequency on hard water installations. The SoftClose seat's dual quick-release hinges allow full seat removal for deep cleaning without tools.

Expert Take

The Drake II uses the same flushing platform found in TOTO's commercial installations. The seat shares the same finish lot as the bowl porcelain. For a renovation where this toilet will serve 20-plus years, this package minimizes regret risk more than any other option at its price tier.

Check price on Amazon
Bottom Line: The TOTO Drake II complete package sets the standard for toilet-plus-seat bundles, delivering a maximum MaP score and WaterSense efficiency in a confirmed-compatible kit that installs cleanly.
#2
Best Clog Resistance

American Standard Champion 4 Complete Slow-Close Seat Package

4.6 Best For: Households with frequent clogging history or heavy use

The American Standard Champion 4 package leads the market in pure clog prevention thanks to a 2-3/8-inch fully glazed trapway and a 4-inch accelerator flush valve that releases the entire tank volume in one unimpeded surge.

Flush Score (MaP)1,000 g
Water Use1.6 GPF
WaterSenseNot Certified
Seat TypeSlow-Close EverClean
Trapway2-3/8" fully glazed
Pros
  • Widest fully glazed trapway in residential category
  • 1,000-gram MaP score confirmed
  • EverClean surface inhibits bacteria and mold
  • 4-inch flush valve dramatically increases flow rate
  • Strong brand warranty and parts availability
Cons
  • 1.6 GPF does not qualify for EPA WaterSense
  • Higher water use than 1.28 GPF competitors
  • Flush is noticeably loud due to high-volume valve design

American Standard designed the Champion 4 around clog elimination. A standard toilet trapway measures around 1-3/4 inches; the Champion 4 measures 2-3/8 inches in diameter with a fully glazed EverClean coating through the entire passage. The 4-inch flush valve is 60% larger than a standard 2.5-inch valve, generating stronger hydraulic force per flush. The EverClean seat bonds antimicrobial protection at the material level so it does not wear off with cleaning. Plumbing professionals frequently recommend this package for vacation properties and rental units where unpredictable use makes clog prevention the top priority.

Expert Take

No residential complete package matches the Champion 4's trapway diameter plus flush valve size combination. For problem-prone plumbing, the higher water use is a worthwhile trade-off against service call costs.

Check price on Amazon
Bottom Line: The Champion 4 complete package is the definitive choice when clog resistance outweighs water efficiency, with industry-leading trapway dimensions and a confirmed maximum MaP rating.
#3
Best One-Piece Package

TOTO UltraMax II One-Piece Elongated 1.28 GPF Complete Package

4.7 Best For: Buyers prioritizing easy cleaning and premium appearance

The TOTO UltraMax II delivers the same Double Cyclone flush platform as the Drake II in a seamless one-piece housing with no exposed tank-to-bowl junction, which makes weekly cleaning significantly faster while also eliminating the most common source of two-piece toilet leaks.

Flush Score (MaP)1,000 g
Water Use1.28 GPF
WaterSenseCertified
Seat TypeSoftClose
DesignSeamless one-piece
Pros
  • 1,000-gram MaP score with 1.28 GPF efficiency
  • No tank-to-bowl seam to clean or leak from
  • CEFIONTECT glazing on all wetted surfaces
  • SoftClose seat included in the package
  • ADA comfort height (16.5 inches seat height)
Cons
  • Heavier than two-piece packages, may require two people to set
  • Higher upfront cost than comparable two-piece models

The UltraMax II shares the same Double Cyclone flushing platform as the Drake II. The meaningful difference is form: one-piece construction eliminates the tank gasket joint, which is the most common source of two-piece toilet leaks over time, and removes the seam at the back of the bowl where mold accumulates. The 16.5-inch rim height meets ADA comfort-height requirements and benefits users with knee or hip concerns. Owner reviews consistently highlight the quick-release seat hinges as making full seat removal for deep cleaning a 30-second task rather than the corroded-bolt ordeal common with older seats.

Expert Take

Every dollar the UltraMax II costs above two-piece pricing buys fewer seams, fewer joints, and a faster cleaning routine over a 15-to-25-year ownership period.

Check price on Amazon
Bottom Line: The UltraMax II complete package earns its premium with seamless construction, a maximum MaP flush score, and a seat finish that matches the CEFIONTECT bowl precisely.
#4
Best Budget Package

American Standard Cadet 3 FloWise Complete Two-Piece Package

4.2 Best For: Remodelers replacing multiple toilets on a budget

The Cadet 3 FloWise complete package offers EPA WaterSense certification, an 800-gram MaP score, and a confirmed-compatible slow-close seat at one of the lowest price points among major-brand complete packages, making it the go-to choice for multi-bathroom projects where overall cost matters.

Flush Score (MaP)800 g
Water Use1.28 GPF
WaterSenseCertified
Seat TypeSlow-Close
Bowl OptionsRound and Elongated
Pros
  • WaterSense certified at 1.28 GPF
  • Available in both round and elongated bowl options
  • Strong parts availability nationwide
  • Siphon-action flushing with fully glazed trapway
  • American Standard warranty support
Cons
  • 800-gram MaP score does not match premium picks
  • No antimicrobial or special ceramic coating

The Cadet 3 platform has been in production long enough that replacement parts are stocked at virtually every hardware store in North America. For a rental property or home remodel replacing three or four toilets at once, this consistency simplifies future maintenance. The round bowl configuration is worth noting for small bathrooms: a round bowl projects about 2 inches less than an elongated model, which can determine whether traffic flow is comfortable or cramped in bathrooms under 60 inches deep. The Cadet 3 is one of the few packages offering both configurations at this price tier.

Expert Take

For outfitting a rental property or replacing three bathrooms at once, the Cadet 3 performs the calculus correctly: WaterSense savings, a slow-close seat, and American Standard parts support for a fraction of premium package pricing.

Check price on Amazon
Bottom Line: The Cadet 3 complete package is the smart budget choice for multi-unit projects, combining WaterSense efficiency with a slow-close seat and long-term parts availability.
#5
Best Modern Style Package

Woodbridge T-0001 Dual Flush One-Piece Complete Package

4.3 Best For: Contemporary bathroom designs with concealed trapway

The Woodbridge T-0001 package presents a fully skirted, concealed-trapway one-piece profile at a price well below European competitors offering similar aesthetics, with dual-flush operation confirmed by EPA WaterSense certification and a soft-close seat included in the box.

Flush Score (MaP)800 g
Water Use1.28 / 0.8 GPF dual flush
WaterSenseCertified
Seat TypeSoft-Close
TrapwayFully concealed skirted
Pros
  • Fully skirted profile with no exposed trapway curves
  • Dual-flush button on top of tank: 1.28 and 0.8 GPF
  • WaterSense certified for both flush modes
  • Soft-close seat with color-matched finish
  • Compact 27.5-inch depth fits smaller bathrooms
Cons
  • MaP score of 800 g is adequate but not maximum-rated
  • Dual-flush button mechanism requires periodic adjustment
  • Fewer service parts available locally vs. TOTO or American Standard

The T-0001's skirted design replaces the exposed S-curve trapway with a flat vertical panel from bowl base to floor, letting a mop or cloth reach the full perimeter without navigating curves. The dual-flush top button selects between 1.28 GPF and 0.8 GPF, with the full flush delivering an 800-gram MaP performance adequate for typical household use. The seat is manufactured to match the bowl glaze within the same production batch, avoiding the subtle color shift that buyers encounter when ordering seats and bowls separately from different production lots.

Expert Take

The T-0001 delivers European skirted aesthetics at mid-tier pricing. The 800-gram MaP score is workable for most families, and dual-flush savings are real in households where the full flush is used by default.

Check price on Amazon
Bottom Line: The Woodbridge T-0001 complete package is the best design-forward option under its price tier, with skirted concealment, dual-flush savings, and a color-matched soft-close seat.
#6
Best Dual Flush Package

TOTO Aquia IV Two-Piece Dual Flush 1.0/0.8 GPF Complete Package

4.4 Best For: Water-conserving households and drought-prone regions

The TOTO Aquia IV complete package pairs TOTO's CEFIONTECT glaze and Tornado Flush technology with dual-mode operation at 1.0 and 0.8 GPF, achieving EPA WaterSense certification at the lowest water volume available in a gravity-fed complete package from a major brand.

Flush Score (MaP)700 g (full flush)
Water Use1.0 / 0.8 GPF
WaterSenseCertified
Seat TypeSoftClose
Flush TechTornado Flush (two-nozzle)
Pros
  • Lowest GPF among complete packages with WaterSense certification
  • Tornado Flush cleans entire bowl at minimal water volume
  • CEFIONTECT glaze reduces cleaning effort
  • TOTO SoftClose seat included
  • Dual-flush handle selects mode intuitively
Cons
  • 700-gram full-flush MaP score below champion-tier models
  • May require two flushes for heavy solid waste in some conditions

The Aquia IV uses TOTO's Tornado Flush design, routing water through two nozzles to create a centrifugal swirling action rather than a direct downward pour through rim holes. This generates enough hydraulic momentum to move waste at lower total water volumes than traditional siphon designs, with the 0.8 GPF partial flush among the lowest available in gravity-fed residential toilets. Many water utilities offer rebates of $50 to $150 per toilet for WaterSense replacements; the Aquia IV's dual-flush range maximizes the rebate argument. The 700-gram full-flush MaP score is sufficient for typical household use but is a step below the Drake II's 1,000-gram ceiling.

Expert Take

Replacing a 3.5 GPF toilet with the Aquia IV saves 2.5 gallons per partial flush. A family of four at eight flushes per person per day saves roughly 73,000 gallons per year, a meaningful reduction in states with tiered water pricing.

Check price on Amazon
Bottom Line: The TOTO Aquia IV complete package is the best water-saving choice in the category, with ultra-low dual-flush operation, Tornado Flush bowl cleaning, and TOTO's SoftClose seat included.
#7
Best Mid-Range Package

Kohler Cimarron Comfort Height Elongated 1.28 GPF Complete Package

4.3 Best For: Buyers wanting Kohler quality with maximum MaP performance

The Kohler Cimarron complete package achieves a 1,000-gram MaP score at 1.28 GPF with Kohler's AquaPiston canister flush technology, which delivers a 360-degree water entry into the bowl versus the standard one-direction flapper valve, and pairs it with Kohler's Quiet-Close seat.

Flush Score (MaP)1,000 g
Water Use1.28 GPF
WaterSenseCertified
Seat TypeQuiet-Close
Flush TechAquaPiston canister
Pros
  • 1,000-gram MaP score at WaterSense efficiency
  • AquaPiston canister offers faster, more complete flush cycle
  • Quiet-Close seat prevents lid slamming
  • Kohler's wide color range and parts network
  • Comfort height (16.5 inches rim) for accessibility
Cons
  • Canister flush valves can be pricier to replace than standard flappers
  • Slightly higher cost than American Standard equivalents

Kohler's AquaPiston canister lifts straight up to allow water to enter the bowl from 360 degrees simultaneously, versus a flapper that opens in one direction. This uniform water distribution contributes to the Cimarron's consistent 1,000-gram MaP certification. The Cimarron package suits master bathrooms in owner-occupied homes where Kohler's dense service network matters over the full ownership period: replacement canisters, seat hinges, and fill valves are available same-day from virtually any plumber in North America.

Expert Take

The Cimarron achieves what few two-piece packages manage: maximum MaP score plus WaterSense compliance, within the Kohler ecosystem. The AquaPiston canister offers a long-term reliability advantage over traditional flappers.

Check price on Amazon
Bottom Line: The Kohler Cimarron complete package is the top mid-range choice for Kohler loyalists and buyers who want 1,000-gram MaP performance with AquaPiston reliability and a Quiet-Close seat included.

Best Value Modern Package

Swiss Madison Well Made Forever Ivy One-Piece Dual Flush Complete Package

4.1 Best For: Design-conscious buyers wanting a European look at accessible pricing

The Swiss Madison Ivy package offers a rimless, skirted one-piece design with dual-flush operation and a soft-close seat at a price that undercuts comparable European-style packages significantly, though its MaP score is lower than premium alternatives and its local parts support is more limited.

Flush Score (MaP)600 g
Water Use1.28 / 0.8 GPF
WaterSenseCertified
Seat TypeSoft-Close Quick-Release
Bowl DesignRimless
Pros
  • Rimless bowl design eliminates under-rim cleaning
  • Skirted exterior conceals trapway completely
  • Dual-flush WaterSense certified
  • Soft-close quick-release seat included
  • Compact footprint suits modern bathroom aesthetics
Cons
  • 600-gram MaP score is the lowest among our picks
  • Limited North American parts availability compared to major brands
  • Owner reviews note occasional need for double-flushing with heavy loads

The Ivy's rimless bowl eliminates the under-rim channel where mold, scale, and bacteria accumulate out of sight in traditional designs. Cleaning requires no angled mirror or specialty tool, just a standard brush. The 600-gram MaP score suits powder rooms, guest baths, and low-traffic master baths in one-to-two-person households; for a family bathroom with three or more daily users, the lower score may result in occasional double-flushing with heavy solid waste. Buyers in rural areas should confirm a local plumber has familiarity with Swiss Madison parts before selecting this for a primary bathroom.

Expert Take

The Ivy delivers rimless hygiene and skirted aesthetics at a price impossible to match from European brands. The 600-gram MaP score is the honest limitation: right context, reliable performance; wrong context (high-traffic family bath), and you will encounter its ceiling.

Check price on Amazon
Bottom Line: The Swiss Madison Ivy complete package is the best rimless skirted design at its price point, ideal for powder rooms and low-to-moderate-use bathrooms where aesthetics and cleaning ease are the top priorities.

What Should You Look for When Buying a Complete Toilet Package?

When evaluating complete toilet packages, the four most important specifications are MaP flush score (target 800 grams minimum, 1,000 grams for heavy use), GPF water efficiency (1.28 GPF qualifies for EPA WaterSense; 1.6 GPF does not), trapway diameter and glazing (fully glazed 2-inch-plus trapways resist clogs), and confirmed seat compatibility (the seat finish, shape, and hinge spacing should match the bowl from the same manufacturer lot).

Beyond specifications, installation logistics matter: verify rough-in distance before ordering (most US homes are 12 inches, but older homes may be 10 or 14 inches), confirm the package includes all gaskets and bolts, and check whether the seat uses standard or proprietary mounting hardware that could complicate future replacement.

Expert Take

MaP testing is the only independent protocol that measures actual solid-waste flush capacity. Manufacturer "powerful flush" claims are marketing language. A published MaP score from map-testing.com is verifiable data -- always check it before trusting any box claim.

Does the Seat Material in a Complete Package Actually Matter?

Yes, seat material affects durability, weight, feel, and maintenance. Polypropylene seats are lighter and less expensive but can flex under heavy use; enameled wood seats feel more substantial but are susceptible to chipping at the hinge area; and molded solid plastic composite seats balance weight and durability for most residential applications. The seat finish needs to color-match the bowl, which is why manufacturer-packaged seats that come from the same production run as the bowl are more reliable color matches than aftermarket replacements.

Soft-close and quick-release hinge mechanisms are the two features most consistently praised in owner reviews across all brands. Quick-release allows the seat to unclip for thorough cleaning without tools, which significantly reduces the effort of maintaining a hygienic installation long-term.

How Much Water Can You Save by Switching to a Complete WaterSense Package?

Replacing a pre-1994 3.5 GPF toilet with a WaterSense 1.28 GPF package saves approximately 2.22 gallons per flush. At the EPA's average of 20 household flushes per day, that is roughly 16,000 gallons per household per year. Replacing a 1.6 GPF toilet with a 1.28 GPF WaterSense model saves approximately 6,400 gallons per year. Many utilities offer rebates of $25 to $150 per WaterSense toilet; the EPA's rebate finder at epa.gov/watersense locates programs by zip code.

Expert Take

The EPA estimates that replacing all older US toilets with WaterSense models would save approximately 520 billion gallons per year. A four-person household replacing two 3.5 GPF toilets with WaterSense packages could cut annual water bills by $50 to $120 depending on local rates.

Is a Two-Piece or One-Piece Package Better for Home Installation?

Two-piece packages are easier for a solo installer: the bowl and tank ship separately, limiting single-lift weight to 40 to 55 pounds per component. One-piece units weigh 80 to 120 pounds and typically require two people to set safely. The trade-off is that one-piece toilets eliminate the tank-to-bowl gasket joint, the most common source of minor leaks in two-piece installations over time. For DIY solo installs, a two-piece package is the practical choice; for a plumber-assisted install, one-piece packages reduce long-term maintenance by removing that failure point.

Which Complete Toilet Packages Qualify for Utility Rebates?

Any complete package containing an EPA WaterSense-certified toilet qualifies for rebates offered by participating water utilities. From our picks, the TOTO Drake II, TOTO UltraMax II, TOTO Aquia IV, Kohler Highline Classic, Kohler Cimarron, American Standard Cadet 3 FloWise, Woodbridge T-0001, Swiss Madison Ivy, and Gerber Viper all carry WaterSense certification. The American Standard Champion 4 does not qualify because it uses 1.6 GPF, which is above the 1.28 GPF WaterSense threshold.

To find utility rebates in your area, use the WaterSense rebate finder at epa.gov/watersense/rebate-finder. Some states like California, Texas, and Florida have especially generous rebate programs through local water agencies that can offset a significant portion of the package purchase price.

Frequently Asked Questions

What is included in a complete toilet package?

A complete toilet package typically includes the toilet bowl, tank, tank-to-bowl hardware (bolts and gasket), a toilet seat with hinges, and sometimes the wax ring and closet bolts for mounting. Always read the box contents carefully, as some packages omit the wax ring and bolts, requiring a separate purchase before installation.

Are complete toilet packages cheaper than buying parts separately?

Yes, in most cases. Manufacturers bundle at a slight discount versus individual component pricing, and you avoid separate compatibility research. Buying a matching seat separately often costs as much as the bundle discount, so net savings are real even if modest.

What does MaP score mean on a toilet?

MaP (Maximum Performance) testing is an independent protocol that measures how many grams of solid waste a toilet can flush in a single flush. Scores range from under 100 grams to 1,000 grams (the maximum certified). A score of 600 grams is acceptable for light use; 800 grams is suitable for most households; 1,000 grams is optimal for heavy-use or problem-prone applications. MaP test results are published publicly at map-testing.com.

What is EPA WaterSense certification for toilets?

EPA WaterSense identifies toilets using 1.28 GPF or less that independently pass a minimum 350-gram flush performance test. Certified models use at least 20% less water than the federal 1.6 GPF standard while meeting verified performance requirements.

Can I use a different seat than the one included in the package?

Yes, but matching is the challenge. Color names like "Cotton White" and "Biscuit" differ between brands and even between production runs. If you want an upgrade (like a bidet seat), confirm hinge hole spacing and bowl shape compatibility before purchasing separately.

What rough-in size do I need for a complete toilet package?

Rough-in is the distance from the finished wall behind the toilet to the center of the floor drain. Most US homes built after 1970 use a 12-inch rough-in. Older homes may have 10-inch or 14-inch rough-ins. Measure before ordering; installing a 12-inch toilet on a 10-inch rough-in will leave a gap at the wall, and it may not fit at all on a 14-inch rough-in. TOTO Drake packages are available in all three sizes.

How long does it take to install a complete toilet package?

A reasonably experienced DIYer can replace a toilet in 45 to 90 minutes: shut off water, remove old toilet, set wax ring, lower bowl onto flange bolts, set tank, connect supply line, attach seat. Two-piece packages take 15 to 20 minutes longer than one-piece due to the separate tank installation step.

Do complete toilet packages include the wax ring?

Not always. Some premium packages include a wax ring and closet bolts; many do not. Check the package contents list on the product page. Wax rings cost $5 to $15 and are available at any hardware store, so it is not a significant cost to add separately, but discovering the omission at installation time after shutting off water is inconvenient.

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

Standard height toilets have a rim height of 14 to 15 inches; comfort height (also called chair height or ADA-compliant) measures 16 to 18 inches at the rim. Most adults find comfort height easier to sit down on and rise from, particularly those with knee or hip issues. The TOTO Drake II, UltraMax II, and Kohler Cimarron complete packages all offer comfort height configurations.

Is a one-piece or two-piece toilet harder to clean?

One-piece toilets are generally easier to clean because there is no tank-to-bowl seam where dust, mold, and mineral scale can accumulate. Two-piece toilets have a visible joint at the back of the bowl that requires a cloth or brush to clean around. Over a 20-year ownership period, the cleaning time difference is meaningful, which is one reason one-piece packages carry a price premium.

What is a skirted toilet in a complete package?

A skirted toilet has a flat vertical panel concealing the exposed trapway curves that traditional toilets show. This creates a cleaner visual line and faster floor cleaning. The Woodbridge T-0001 and Swiss Madison Ivy in our list are fully skirted designs.

What is CEFIONTECT glaze on TOTO toilets?

CEFIONTECT is TOTO's proprietary titanium-oxide ceramic glaze that is baked into the porcelain surface during manufacturing. It creates an ion-barrier surface that is smoother at the microscopic level than standard ceramic, reducing the adhesion of waste, mineral deposits, and bacteria. It is not a coating applied after manufacture, so it cannot wear off. TOTO includes it on the Drake II, UltraMax II, and Aquia IV packages.

What is an AquaPiston flush valve on Kohler toilets?

Kohler's AquaPiston is a canister-style flush valve that replaces the traditional flapper design. When the handle is pressed, the canister lifts straight up to allow water to flow into the bowl from 360 degrees simultaneously, versus a flapper that opens in one direction. This creates a faster, more complete bowl wash and is one reason the Kohler Cimarron earns its 1,000-gram MaP score.

Can I install a complete toilet package over an existing wax ring?

No. A compressed existing wax ring cannot form a new seal. Always install a fresh wax ring with every replacement. Reusing an old ring risks sewer gas infiltration and base leaks that cost far more to repair than a $10 wax ring.

Are complete toilet packages available in colors other than white?

Yes. TOTO offers Cotton White, Colonial White, Bone, and Sedona Beige in Drake II configurations. Kohler offers Biscuit, Almond, Ice Grey, and Black in Cimarron and Highline packages. American Standard offers Linen and Bone in Champion 4 and Cadet 3. White and Cotton White are the most consistently stocked at retailers.

What makes the Champion 4 clog resistant compared to other packages?

Two combined design choices: a 2-3/8-inch fully glazed trapway (wider than the typical 1-3/4-inch standard) and a 4-inch accelerator flush valve. The wider trapway allows larger waste volumes to pass without obstruction; the larger valve releases tank water faster, generating stronger hydraulic force through the drain path.

What is Tornado Flush on TOTO toilets?

Tornado Flush, used in the Aquia IV and other TOTO models, routes water through two rim-mounted nozzles at opposing angles to create a centrifugal spinning action across the entire bowl surface. This cleans more surface area per flush than rim-hole designs and moves waste at lower water volumes.

Do toilet packages come with a warranty?

Yes. TOTO, Kohler, and American Standard offer limited lifetime warranties on porcelain and one-year or longer warranties on flush mechanisms. Woodbridge and Swiss Madison offer one-to-five-year component warranties. Register with the manufacturer within 30 to 90 days of purchase to activate coverage.

How do I find utility rebates for WaterSense toilet packages?

Use the EPA's WaterSense rebate finder at epa.gov/watersense, which allows you to enter your zip code to see participating utilities and rebate amounts in your service area. Keep your purchase receipt and product packaging showing the WaterSense certification mark, as most utilities require these for rebate applications.

What is the best complete toilet package for a small bathroom?

The Woodbridge T-0001 and Swiss Madison Ivy both have compact footprints under 28 inches in depth. The American Standard Cadet 3 in round bowl projects about 2 inches less than its elongated version. Always measure your rough-in and available floor depth before ordering.

Prioritize clog resistance? Choose the American Standard Champion 4 with its 2-3/8-inch trapway. Replacing multiple toilets on a budget? The Cadet 3 FloWise delivers WaterSense efficiency and slow-close seat at the lowest major-brand price. Want a skirted contemporary design? The Woodbridge T-0001 wins on aesthetics and dual-flush water savings.
