Toilet Buying Checklist: 15 Questions Before You Purchase

From rough-in distance to MaP flush scores, these are the 15 questions that separate a confident toilet purchase from a costly mistake. Answer all 15 before you add anything to your cart.

Why Trust Best Flushing Toilets

Research updated June 2026.

Quick Answer

Before buying any toilet, confirm your rough-in measurement, bowl shape, flush performance (MaP score of 500 g or higher), GPF rating, and height preference. Missing even one of these five core specs can mean a return trip to the store or a leaking, ill-fitting installation that costs more to fix than the toilet itself.

Buying a new toilet sounds straightforward until you are standing in the plumbing aisle staring at sixty nearly identical white porcelain units with no idea whether any of them will fit your bathroom, flush reliably, or save you money over time. This checklist turns a confusing purchase into a logical, step-by-step process. Work through each question in order. By question 15, you will have a shortlist of verified models and the confidence to buy without second-guessing.

This guide is part of our broader resource on the best flushing toilets currently available. Refer to that page for specific model recommendations once you have answered the questions below and know exactly what you need.

What is your rough-in distance, and does the toilet match it?

The rough-in distance is measured from the finished wall behind the toilet to the center of the floor drain (the closet flange). The vast majority of North American homes use a 12-inch rough-in, but 10-inch and 14-inch rough-ins exist, particularly in older construction and manufactured homes. If you install a toilet designed for a 12-inch rough-in into a 10-inch space, the tank will press against the wall; in a 14-inch space, there will be a gap that looks wrong and compromises the seal. Always measure before purchasing.

How to measure: Use a tape measure from the wall (not the baseboard) to the center of the floor bolt caps on either side of the toilet base. If you have no existing toilet, measure to the center of the closet flange. Write that number down and match it to the rough-in specification on the toilet's product page.

Expert Take

A 12-inch rough-in toilet can be installed in a 14-inch rough-in space with a toilet offset flange, but that adds labor and cost. It is always cleaner to buy the toilet that matches your actual measurement. TOTO and Kohler both publish the rough-in spec prominently in product titles, which makes searching far easier.

Does the toilet have a MaP score of at least 500 grams?

Maximum Performance (MaP) testing, administered through map-testing.com, measures how many grams of solid waste a toilet can clear in a single flush. A score of 500 g is the minimum acceptable threshold for residential use; 800 g is considered good; 1,000 g (the maximum) is excellent. Models like the TOTO Drake and TOTO UltraMax II consistently earn 1,000 g MaP scores, while some entry-level or design-forward models score as low as 250 g, which creates chronic clogging problems.

The MaP database is publicly searchable at map-testing.com. Enter any model number and the score appears immediately. If a toilet is not listed, that is itself a warning sign. Every serious manufacturer submits their flagship models for independent testing. Look for the MaP score in the same place you look for WaterSense certification.

MaP Score Performance Level Suitable For Example Models
1,000 g Excellent High-traffic, families, heavy use TOTO Drake, UltraMax II, Champion 4
800-999 g Very Good Most residential applications Kohler Cimarron, Gerber Avalanche
500-799 g Acceptable Light residential use Many WaterSense-certified entry models
Below 500 g Inadequate Not recommended for daily use Varies by manufacturer

Is the toilet EPA WaterSense certified, and what is the GPF?

EPA WaterSense certification means the toilet uses no more than 1.28 gallons per flush (GPF) and has passed independent performance testing to confirm it still flushes effectively at that reduced volume. Standard toilets manufactured before 1994 used 3.5 to 7 GPF; toilets built between 1994 and 2014 typically used 1.6 GPF; modern WaterSense-certified models use 1.28 GPF or less. Some ultra-high-efficiency models, including the TOTO Aquia IV, use 1.0/0.8 GPF in dual-flush configuration.

At current U.S. average water rates, replacing a pre-1994 toilet with a 1.28 GPF WaterSense model saves roughly 13,000 gallons per person per year, according to EPA data. A family of four can expect annual savings of more than $100 on their combined water and sewer bill in most municipalities. Some water utilities offer rebates of $50 to $200 for WaterSense-certified replacements; check your local utility's website before purchasing.

Expert Take

Do not assume that lower GPF means weaker flushing. The TOTO Drake II at 1.28 GPF earns a 1,000 g MaP score, outperforming many older 1.6 GPF models. WaterSense certification verifies that efficiency does not come at the expense of performance.

What bowl shape fits your bathroom: elongated or round?

Elongated toilet bowls measure approximately 18.5 inches from the seat hinge to the front of the bowl; round bowls measure approximately 16.5 inches. Elongated bowls are generally considered more comfortable for adults, but round bowls save about 2 inches of floor space, which matters significantly in tight half-baths or powder rooms where clearance is limited. Comfort and space are both valid factors, and the right choice depends on your specific bathroom dimensions.

Before selecting a bowl shape, measure the distance from the wall behind the toilet to any obstruction in front of it (a door swing, a cabinet, a vanity edge). The National Kitchen and Bath Association recommends at least 21 inches of clearance in front of the toilet; 30 inches is considered comfortable. If your clearance is exactly 21 inches, a round bowl gives you more margin. If you have 28 inches or more, elongated is usually the better ergonomic choice.

One-piece or two-piece: which suits your needs?

Two-piece toilets (separate tank and bowl) are typically less expensive to manufacture and ship, easier to maneuver into tight installation spaces, and cheaper to repair because individual components are widely available. One-piece toilets have the tank and bowl fused into a single seamless unit, which eliminates the joint between tank and bowl (a common leak point), makes cleaning easier, and generally looks sleeker. One-piece models tend to cost more but offer long-term maintenance advantages.

For most replacement scenarios, a two-piece toilet is the practical default. The TOTO Drake and Kohler Highline are two-piece workhorses with decades of proven reliability. For master bathrooms or design-forward renovations where cleaning ease and aesthetics matter more than upfront cost, one-piece models like the TOTO UltraMax II or Woodbridge T-0001 offer genuine advantages. The Woodbridge T-0001 in particular brings a one-piece skirted design at a price point significantly lower than TOTO equivalents.

What is the toilet height, and who will be using this bathroom?

Standard toilet height (rim to floor) is 14 to 15 inches; comfort height (sometimes called chair height) is 16 to 18 inches, which places the seated position closer to the height of a standard chair. Comfort height toilets are recommended by the Americans with Disabilities Act for ADA-compliant installations, and are generally preferred by taller adults, seniors, and anyone with knee or hip joint issues. Standard height is often preferred by children and shorter adults because it allows feet to rest flat on the floor.

Expert Take

If the bathroom serves multiple users across different age groups, comfort height is usually the safer default. The ergonomic benefit for adults is significant, and children can use a step stool or toilet training seat as needed. Both TOTO and Kohler clearly label their comfort height models in product specifications.

What flush mechanism is right for your household?

Gravity-flush toilets use the weight of water falling from the tank to create flushing force; they are quiet, reliable, and easy to repair without special tools. Pressure-assist toilets use compressed air in a sealed pressure vessel inside the tank to produce a significantly more powerful flush, but they are louder and more expensive to service. Dual-flush toilets offer two separate flush volumes (typically 0.8 GPF for liquid waste and 1.6 GPF for solid waste), maximizing water savings without compromising performance when a full flush is needed.

For most residential applications, a gravity-flush toilet with a high MaP score is the best balance of performance, quiet operation, and long-term repairability. Pressure-assist models make the most sense in commercial settings or bathrooms with chronic clogging history caused by weak water pressure. Dual-flush models shine in households that are serious about water conservation and willing to pay attention to which button they press.

Does the trapway size match your usage requirements?

The trapway is the S-shaped passage inside the toilet base through which waste exits the bowl. A larger trapway diameter reduces clog risk by allowing bulkier waste to pass without restriction. Standard trapways measure approximately 2 inches in diameter; full-size trapways measure 2.125 inches; oversized designs (such as the American Standard Champion 4's fully glazed 2.375-inch trapway) are specifically engineered to resist clogging. A fully glazed trapway adds a smooth ceramic coating to the interior passage, further reducing friction and the likelihood of material catching on the surface.

Model Trapway Size Glazed MaP Score GPF
American Standard Champion 4 2.375 in Yes (fully) 1,000 g 1.6
TOTO Drake II 2.125 in Yes 1,000 g 1.28
Kohler Cimarron 2.125 in Yes 1,000 g 1.28
American Standard Cadet 3 2.125 in Yes 1,000 g 1.28
Woodbridge T-0001 2.125 in Yes 800 g 1.28/0.8

Is the seat included, and is it compatible with the bowl shape?

Many toilets, particularly at mid-range and premium price points, do not include a seat. TOTO's Drake and UltraMax II lines are classic examples: the toilet ships without a seat, requiring a separate purchase. Toilet seats must match the bowl shape (elongated or round) and the seat mounting hole spacing. Some premium seats, including those with soft-close hinges or quick-release mechanisms, require specific bowl contours to fit correctly. Always verify seat compatibility before purchasing separately.

Check the product listing carefully for language such as "seat not included" or "toilet seat sold separately." If a seat is not included, factor the cost of a quality seat (typically between $30 and $150 for a standard slow-close model) into your total budget. For related guidance, see our article on choosing a toilet seat and our guide on toilet seat buying options.

What is the brand's warranty, and how is the customer service reputation?

Toilet warranties vary significantly by brand and component. TOTO offers a limited lifetime warranty on vitreous china and a one-year warranty on electronic components. Kohler's limited lifetime warranty covers the toilet fixture itself but excludes mechanical components such as flappers and fill valves, which have a one-year warranty. American Standard offers a limited lifetime warranty on the china. Gerber provides a limited lifetime warranty on the bowl and tank, with one year on mechanical parts. The warranty matters most if you ever need to make a claim, which is where customer service reputation is equally important.

Expert Take

TOTO consistently earns the highest marks in owner satisfaction surveys for both product reliability and after-purchase support. Kohler's wide retail distribution means parts are available almost everywhere, which reduces dependency on the brand's customer service for routine maintenance. For budget-conscious buyers, American Standard and Gerber both have strong warranty coverage relative to their price points.

Does the toilet meet your local water efficiency requirements?

Several U.S. states and municipalities have adopted water efficiency standards that exceed the federal 1.6 GPF limit. California, Texas, Georgia, and New York have enacted mandatory low-flow requirements, with California requiring 1.28 GPF or less for all new toilet installations since 2016. Some water districts in drought-prone regions require 1.0 GPF or less. Purchasing a toilet that does not meet local requirements can complicate inspections during home sales and may disqualify you from utility rebate programs.

The EPA WaterSense label (1.28 GPF or less) meets the requirements of all current state-level mandates as of June 2026. If you are in California or another high-restriction state, sticking to WaterSense-certified models eliminates any compliance uncertainty. See our detailed guide on EPA WaterSense certification for a state-by-state breakdown.

Does the installation location require any special configuration?

Basement bathrooms with below-grade drains typically require a macerating (upflush) toilet, which grinds waste and pumps it upward to the main drain stack. Corner installations may need a compact or corner-specific toilet design. Bathrooms with wall-mounted plumbing rather than floor-mounted plumbing require a wall-hung toilet with in-wall carrier system. Standard floor-mounted toilets cannot be installed in these configurations without significant plumbing modification.

If your installation is standard (floor-mounted, floor drain, 12-inch rough-in), this question is a quick pass. If you are finishing a basement, converting a closet, or working with any non-standard plumbing configuration, answer this question before any other spec question because the answer changes everything else on this list.

What surface finish and cleaning features matter to you?

Surface glaze technology significantly affects long-term cleaning effort and staining resistance. TOTO's proprietary CeFiONtect (Cefiontect) glaze applies an extremely smooth, ion-barrier coating to the porcelain that resists waste adhesion and mineral buildup. American Standard's EverClean surface uses antimicrobial technology to inhibit mold and bacteria growth. Toilets without special glaze coatings are more porous at a microscopic level, which allows staining agents to penetrate the ceramic over time, making cleaning harder as the toilet ages.

Expert Take

TOTO's CeFiONtect glaze has a measurable, documented effect on surface friction. In comparison testing, uncoated toilet bowls accumulate visible staining significantly faster under identical use conditions. If low-maintenance cleaning is a priority, this feature alone can justify choosing TOTO over a similarly specified competitor at a comparable price point.

Is the toilet compatible with your existing supply line and shut-off valve?

Most residential toilet supply lines connect with a standard 3/8-inch compression fitting at the shut-off valve and a 7/8-inch ballcock coupling nut at the fill valve. This is the universal standard for floor-mounted toilets, so supply line compatibility is rarely an issue when replacing a standard toilet. However, wall-hung toilets, some slim-tank designs, and certain imported European models may use different connection sizes or require the supply inlet on the side rather than the bottom of the tank, which can require a new supply line.

Before disposing of your old supply line, check its length as well as its fittings. If your shut-off valve is 8 inches from the floor and your new toilet's tank sits higher than the old one, the supply line may be too short. Supply lines are inexpensive (generally $8 to $25), but it is worth confirming before installation day to avoid a last-minute hardware store run.

What is your total installed budget, including labor if needed?

The toilet's purchase price is only part of the total cost of ownership. If you are hiring a plumber, expect to add $150 to $350 in labor for a standard replacement installation in most U.S. markets. Additional costs may include a new wax ring ($5 to $15), a new supply line ($10 to $25), closet bolts ($5 to $10), and potentially a toilet seat if not included. Factor in any rebates from your local water utility, which can reduce the net cost of a WaterSense-certified model by $50 to $200.

Setting a realistic total budget before you begin shopping prevents scope creep and makes it easier to evaluate trade-offs. A $400 total budget might accommodate a $250 toilet plus $150 in installation supplies, or a $200 toilet plus a $200 seat. A $700 budget opens up mid-range one-piece models with included seats. For guidance on current price tiers across all major brands, see our article on how much a toilet costs.

Brand Quick Reference: Which Brands Answer Which Questions Best

No single brand wins every question, but patterns emerge once you map brand strengths against the checklist above.

TOTO (Drake, Drake II, UltraMax II, Aquia IV) earns the highest marks for MaP performance, CeFiONtect surface finish, and dual-flush efficiency. The Drake II at 1.28 GPF is one of the most comprehensively validated residential toilets available, with a 1,000 g MaP score and decades of proven reliability. The Aquia IV adds a 0.8/1.0 GPF dual-flush option for maximum water savings. TOTO toilets typically do not include seats, which is an important budget consideration.

Kohler (Highline, Cimarron) offers broad retail availability, a wide range of height and bowl shape options, and strong mid-range pricing. The Kohler Highline is particularly well-suited to budget replacement projects where parts availability and DIY repairability matter. The Cimarron adds a more refined aesthetic at a modest price premium. Kohler's AquaPiston flush valve, used across most current models, produces a more consistent flush than older canister designs.

American Standard (Champion 4, Cadet 3) addresses the clogging question most directly. The Champion 4's 2.375-inch fully glazed trapway is the largest available in a standard residential toilet, making it the top choice for households that deal with chronic clogging. The Cadet 3 offers similar clog resistance at a lower price point and includes EverClean antimicrobial surface treatment. American Standard also has one of the strongest retail footprints, with parts available at virtually every hardware store.

Woodbridge (T-0001) brings one-piece skirted design to a price range previously occupied only by two-piece toilets. The T-0001's concealed trapway is fully skirted, eliminating the external trap curves that collect dust and are difficult to clean. It earns an 800 g MaP score and 1.28/0.8 GPF dual-flush, which is solid performance for its price tier. Woodbridge is a strong choice when aesthetics and cleaning ease are weighted heavily in the decision.

Swiss Madison and Gerber round out the mainstream residential market. Swiss Madison's St. Tropez and Clarence models offer European-influenced skirted designs at competitive prices, though MaP testing data is less comprehensively published than for TOTO or American Standard. Gerber's Avalanche and Ultra Flush lines are frequently cited by plumbing professionals as reliable workhorses with strong warranty support.

Expert Take

If you are replacing a toilet in a rental property or high-traffic bathroom where clog resistance is the primary concern, the American Standard Champion 4 or Cadet 3 is the most defensible choice. If you are buying for a master bathroom renovation where long-term quality matters most, TOTO's Drake II or UltraMax II represents the benchmark. For budget-constrained projects where style still matters, the Woodbridge T-0001 overdelivers at its price point.

Installation Red Flags to Check Before Purchase Day

The checklist above focuses on the toilet itself, but the installation environment can derail even the best purchase. Before the toilet arrives, check for these common issues.

Rotted subfloor around the flange: A soft or springy floor near the toilet base often indicates water damage from a previous seal failure. If the subfloor is compromised, it must be repaired before installation; a new toilet will not fix an unstable foundation. This typically adds $200 to $600 to the project cost if a contractor is involved.

Damaged or misaligned closet flange: The closet flange should sit at finished floor level, not below it. A flange that sits more than 0.25 inches below the floor surface requires a flange extension kit to ensure a proper wax ring seal. Installing over a sunken flange is one of the most common causes of toilet base leaks.

Corroded shut-off valve: If the shut-off valve under the toilet has not been operated in years, it may not fully close, or it may leak when turned. Testing the valve before installation day costs nothing and prevents a plumbing emergency during installation. If the valve is stuck or corroded, plan to replace it.

Frequently Asked Questions

How do I measure my rough-in if I have an existing toilet?

Measure from the finished wall (not the baseboard) to the center of one of the two bolt caps at the base of the toilet. The bolt caps sit directly above the closet flange bolts. Most North American homes measure exactly 12 inches, but older homes and manufactured housing often use 10 or 14 inches.

Can I install a 10-inch rough-in toilet in a 12-inch rough-in space?

Yes, but there will be a gap between the tank and the wall, which looks incorrect and may leave the wall surface behind the toilet exposed and difficult to clean. It is generally better to buy a toilet that matches your actual rough-in measurement rather than using adapters or accepting a gap.

What MaP score do plumbing professionals recommend for family bathrooms?

Most plumbing professionals recommend a minimum MaP score of 600 g for family bathrooms, with 800 g or higher preferred for households with children or heavy use. A score of 1,000 g eliminates clogging as a concern in virtually all residential scenarios.

Is a 1.28 GPF toilet enough to flush solid waste effectively?

Yes, when the toilet has a high MaP score. The TOTO Drake II at 1.28 GPF earns a 1,000 g MaP score, demonstrating that GPF and flushing power are independent variables. A toilet's flush system design (particularly trap diameter, siphon jet placement, and bowl geometry) determines performance more than the GPF rating alone.

What is the difference between a skirted and an exposed trapway toilet?

An exposed trapway toilet has a visible S-curve profile on the outside of the toilet base, which is the standard design for most North American toilets. A skirted trapway toilet has a flat, smooth side panel that covers the external trap curve, creating a cleaner appearance and eliminating the curved surface that collects dust. Skirted toilets generally cost more and may require specific mounting hardware.

Does toilet height affect flush performance?

No. Toilet height (comfort vs. standard) is determined by the total height of the bowl and base and does not affect the flushing mechanism. Performance is determined by tank design, flush valve size, trap diameter, and bowl geometry, none of which are related to seated height.

Are dual-flush toilets harder to repair?

Dual-flush toilets use either a button-operated or handle-operated mechanism that controls two separate flush volumes. The fill valve and flapper (or cartridge, in button-flush designs) can require brand-specific replacement parts, making repairs slightly more involved than standard single-flush systems. Replacement parts are widely available for major brands, but generic parts may not be compatible.

Does toilet bowl shape affect MaP score?

MaP scores are tested per specific model, not per bowl shape category. Some elongated bowl models earn higher MaP scores than their round counterparts from the same manufacturer because bowl volume and water jet alignment differ. Always look up the MaP score for the specific model you are purchasing, not for the product line generally.

What is TOTO CeFiONtect and is it worth the premium?

CeFiONtect is TOTO's proprietary ionic barrier glaze that makes the porcelain surface extremely smooth at a microscopic level, reducing the ability of waste, bacteria, and mineral deposits to adhere. Independent surface testing confirms measurably lower friction coefficients compared to standard glaze. For households that prefer to clean less frequently or live in hard-water areas, the long-term cleaning benefit justifies the modest premium over comparable non-TOTO models.

Do I need to hire a plumber to replace a toilet?

A standard toilet replacement is one of the more accessible DIY plumbing projects. It requires no soldering, no pipe cutting, and no specialized tools beyond a wrench, a putty knife, and a wax ring. Most homeowners with basic mechanical confidence can complete a standard replacement in two to three hours. However, if the flange is damaged, the shut-off valve needs replacement, or the subfloor is compromised, professional involvement is strongly recommended.

How long should a quality toilet last?

The porcelain bowl and tank of a quality toilet can last 50 years or more with normal use. The mechanical components (fill valve, flapper, flush valve) typically need replacement every 5 to 10 years depending on water quality and use frequency. A toilet's effective service life is therefore indefinite if minor components are replaced as needed, which is why the quality of the china and warranty coverage on the fixture itself matter more than the warranty on mechanical parts.

Can I use a toilet not certified for WaterSense in California?

California's plumbing code (Title 24) requires 1.28 GPF or less for all new toilet installations and replacements that require a permit. Installing a 1.6 GPF toilet in California without a permit may still technically occur (older replacement units are sometimes used without permits), but it will not pass an inspection and may complicate a future home sale if the bathroom is inspected. WaterSense certification at 1.28 GPF meets California's requirements in all jurisdictions.

What is the difference between a pressure-assist and a gravity-flush toilet in practice?

Pressure-assist toilets produce a noticeably louder flush (often described as a powerful whoosh sound) because compressed air forces water into the bowl more forcefully than gravity alone. The result is a more complete, bowl-coating flush that reduces the likelihood of skid marks and secondary waste adhesion. The trade-off is noise and the need for minimum water supply pressure (typically 25 psi or higher) for the pressure vessel to charge properly.

What is a wax ring, and when should I replace it?

A wax ring is a compressible wax seal that sits between the bottom of the toilet base and the closet flange, creating a watertight and odor-proof seal. A wax ring should be replaced every time the toilet is removed, even temporarily. Once compressed during installation, a wax ring conforms to the specific gap between the toilet and flange. Reinstalling the toilet without a new ring almost always results in a leak.

Are Woodbridge toilets reliable for everyday use?

Woodbridge toilets, particularly the T-0001, have accumulated a substantial owner review base over several years of market presence. Aggregated reviews indicate high satisfaction with flushing performance and aesthetics, with some owner reports of fill valve noise in hard-water environments. Woodbridge offers a one-year warranty on mechanical parts and a five-year warranty on the porcelain for most models, which is adequate but less comprehensive than TOTO or Kohler's warranty terms.

What does "fully glazed trapway" mean, and why does it matter?

A fully glazed trapway means the ceramic manufacturer applied the same glaze coating used on the outer porcelain surfaces to the interior of the trap passage as well. Unglazed trapway interiors have a rougher surface texture that can catch toilet paper, hair, and waste solids, increasing clog frequency. A fully glazed trapway dramatically reduces this risk. American Standard specifies full trapway glazing on the Champion 4 and Cadet 3 as a key anti-clog feature.

What happens if I buy the wrong rough-in size?

A toilet with too large a rough-in measurement will have its tank pressing against the wall (or may not physically fit into the space at all). A toilet with too small a rough-in measurement will have a visible gap between the tank and wall. In neither case will the toilet be damaged by the mismatch, but the installation will be aesthetically incorrect and may require offset flanges or significant rework. Most retailers allow returns if the product is uninstalled and in original packaging.

Are smart toilets worth the extra cost?

Smart toilets (integrated bidet, heated seat, automatic lid, dryer) provide genuine comfort and hygiene benefits that are difficult to replicate with accessories. However, they add significant upfront cost, require an electrical outlet near the toilet, and introduce electronic components that may need servicing or replacement over time. For most buyers, a high-quality standard toilet combined with a dedicated bidet seat attachment provides similar functionality at lower cost with easier maintenance.
