Best Flushing Toilets of 2026: Year in Review

The TOTO Drake II has held the top position among independently evaluated flushing toilets for multiple consecutive years because it delivers a verified 1,000-gram MaP score, EPA WaterSense compliance at 1.28 GPF, and TOTO's proprietary CeFiONtect glaze on the bowl surface.

The Drake II uses TOTO's E-Max flushing system, which channels water through a wide 3-inch flush valve and a fully glazed 2 1/8-inch trapway. The result is a consistent, powerful flush that owner reviews frequently describe as reliable across years of daily use. CeFiONtect is an ion-barrier glaze that fills in micro-pores in the vitreous china, preventing waste and mineral deposits from adhering to the bowl surface. Independent plumbers in consumer surveys consistently rate TOTO Drake models as their first recommendation for residential replacement.

The Drake II is available in Cotton White, Colonial White, and Sedona Beige, with round and elongated bowl options. For most buyers the elongated CST454CEFG is the appropriate choice. Rough-in is standard 12 inches, and a 10-inch rough-in version is available as the CST454CEFGT40 for older homes with non-standard plumbing configurations. This model pairs well with TOTO's own SoftClose seat, though any standard elongated seat fits correctly.

The American Standard Champion 4 holds a 1,000-gram MaP score built around a 4-inch accelerator flush valve and a 2 3/8-inch fully glazed trapway, the largest in its class, designed specifically to reduce clogging frequency.

The Champion 4's engineering philosophy prioritizes waste-removal volume over water efficiency. The 4-inch flush valve is physically larger than any other residential toilet valve on the market, opening quickly and releasing a large water volume that generates sufficient hydraulic force to clear the oversized trapway in a single flush. American Standard's EverClean glaze is an antimicrobial surface treatment that inhibits the growth of mold, mildew, and bacteria on the bowl surface. While it differs from TOTO's CeFiONtect in mechanism, owner reviews consistently report easier cleaning and less frequent staining over long ownership periods.

The trade-off is water consumption. At 1.6 GPF, the Champion 4 uses more water per flush than WaterSense-certified models, which matters in drought-prone states or households where the water bill is a consideration. For households with frequent clogging problems, children, or large families where reliability is paramount, the Champion 4's physical design advantages justify the higher water use. See our full best flushing toilets guide for a broader breakdown of how flush system design affects clog risk.

The TOTO UltraMax II delivers the same 1,000-gram MaP score and CeFiONtect bowl glaze as the Drake II in a seamless one-piece form factor that eliminates the tank-to-bowl joint, simplifying cleaning and removing a common leak point.

The UltraMax II's one-piece construction means there is no seam between tank and bowl, removing the rubber gasket joint that is a long-term failure point in two-piece designs. Cleaning is faster because there is no recessed ledge around the tank base to collect moisture and debris. The unit ships heavier than a comparable two-piece system, which is worth planning for at installation time. TOTO includes a SoftClose seat in the MS604114CEFG configuration, which is not true of all TOTO models.

The comfort height of 17.25 inches is slightly taller than the Drake II's 16.5-inch seat height, which some owners with shorter stature find less comfortable. For most adults this distinction is minor. The UltraMax II's quieter flush characteristic compared to the Drake II comes from a slightly different valve geometry that reduces turbulence noise. For master bathrooms, guest bathrooms, or any space where aesthetics and ease of cleaning are a priority, the UltraMax II is the appropriate TOTO selection.

The Kohler Highline Classic is Kohler's entry-level workhorse, widely available, straightforward to install, and backed by Kohler's one-year limited warranty, making it a reliable choice for rental properties and secondary bathrooms where cost is a primary constraint.

The Highline Classic uses Kohler's canister-style flush valve, which opens fully to release water uniformly around the bowl rim. This design is mechanically simple and produces consistent results, though the MaP scores for the Highline line are generally in the 800-gram range rather than the 1,000-gram maximum. For moderate household use this is entirely adequate. Performance gaps are noticeable only under high-demand conditions with unusually large waste loads.

Kohler's parts ecosystem is a genuine advantage. Highline repair kits, replacement flappers, and fill valves are stocked at virtually every hardware store. When a component fails, repair is a hardware-store trip, not a special-order delay. For rental property owners managing multiple units, this parts accessibility justifies the Highline's position over less-common brands.

The TOTO Aquia IV is the manufacturer's dedicated dual-flush offering, with a 1.0 GPF partial flush and 1.28 GPF full flush both qualifying for EPA WaterSense certification as a combined average, alongside a 1,000-gram MaP score on the full flush cycle.

The Aquia IV updated the original Aquia line's flush system to use TOTO's DYNAMAX TORNADO FLUSH technology, which replaced the traditional rim-hole distribution with two nozzle jets that create a centrifugal water motion across the bowl surface. This approach cleans the bowl more completely with less water and eliminates the bacteria-harbouring rim holes found in older toilet designs. The partial flush at 1.0 GPF is sufficient for liquid waste in standard conditions. Owner feedback notes that aggressive use of the partial flush on borderline loads occasionally requires a follow-up flush, but this is characteristic of all dual-flush designs rather than a specific Aquia IV failing.

For households in California, Colorado, Washington, New York, or any municipality offering WaterSense rebate programs, the Aquia IV is one of the highest-qualifying models available. The dual-flush system's average flush volume falls well below the 1.28 GPF WaterSense threshold. Check with your local water utility for rebate eligibility before purchasing, as rebate amounts vary significantly by region. See our best dual flush toilets guide for a full category comparison.

The Kohler Cimarron steps up from the Highline with a larger flush valve, comfort-height bowl, and improved MaP performance in a mid-range package that appeals to buyers who want a better flush than entry-level Kohler without moving to TOTO pricing.

The Cimarron uses a 3-inch canister flush valve that opens more completely and faster than the 2-inch flapper-style valves found in older or entry-level designs. The result is a more forceful initial water surge that improves MaP performance without requiring additional water volume. Kohler publishes the Cimarron with a 1.28 GPF flush and EPA WaterSense certification, meaning it meets the federal efficiency threshold while also qualifying for rebates in WaterSense-participating municipalities.

The Cimarron is available in a wide range of Kohler colors including White, Almond, Biscuit, Dune, and Thunder Grey, which makes it one of the more versatile choices for matching existing bathroom fixtures. The comfort-height bowl at 16.5 inches matches ADA recommended seat height and is consistently better rated for ease of use by older adults in consumer surveys. Our Kohler 2026 roundup has additional detail on how the Cimarron compares to the Santa Rosa and Corbelle.

The Woodbridge T-0001 delivers a skirted concealed-trapway one-piece design at a price point well below comparable TOTO and Kohler skirted models, with dual-flush operation and a soft-close seat included in the box.

Woodbridge is a value-market brand that has grown significantly in online retail channels. The T-0001's appeal is primarily aesthetic and economic: a skirted one-piece design with dual-flush and an included soft-close seat represents significant feature quantity at its price tier. The absence of a published MaP score is a transparency gap that buyers should factor in. Owner reviews in aggregate suggest adequate flush performance for normal residential use, but there is no independent third-party confirmation comparable to the scores published for TOTO, Kohler, or American Standard models.

The skirted exterior conceals the trapway completely, leaving a smooth vertical surface from the bowl base to the floor. This eliminates the difficult-to-clean contoured trapway exterior of traditional exposed designs. For buyers prioritizing a modern aesthetic with easy bathroom cleaning over independently verified flush performance data, the T-0001 is a practical choice. For any buyer in a code-regulated state or eligible for WaterSense rebates, a certified model is a better fit. Check our Woodbridge 2026 guide for additional detail on Woodbridge's catalog.

The American Standard Cadet 3 FloWise combines an accessible 16.5-inch right-height seat with WaterSense-certified 1.28 GPF flushing and a straightforward 3-inch flush valve, making it one of the most accessible affordable options for households with elderly or mobility-limited users.

The Cadet 3 FloWise positions itself squarely between the budget Highline tier and the premium Champion 4. The FloWise designation indicates the WaterSense 1.28 GPF flush volume. At 16.5 inches seat height, it meets ADA comfort height criteria without any modification. The EverClean surface treatment inhibits the growth of bacteria and mold on the bowl surface, which is a meaningful maintenance benefit in bathrooms used by seniors who may find frequent scrubbing difficult.

Owner reviews across thousands of purchases consistently praise the Cadet 3 FloWise for installation simplicity and reliable day-to-day performance. The main limitation relative to the Champion 4 is flush aggression on larger waste loads. For most senior household use cases this distinction rarely arises in practice, but households where the toilet will also see regular use by other family members may find the Champion 4 more appropriate.
