Best MaP 800+ Toilets: High Performance at Lower Cost

The TOTO Drake II earns its top position by combining the highest possible MaP score (1,000 grams) with a 1.28 GPF WaterSense rating and TOTO's proven Double Cyclone flushing technology -- all at a price point accessible to most homeowners.

The Drake II uses a larger 3-inch flush valve paired with a fully glazed trapway to generate the water velocity needed to score 1,000 grams. TOTO's Double Cyclone system channels water through two nozzles rather than rim holes, which means the rim stays cleaner and the bowl rinses evenly on every flush. Aggregated owner reviews across major retail platforms consistently rate the Drake II above 4.5 stars with clog resistance and water savings cited as the top reasons for satisfaction.

The comfort height bowl (approximately 16.5 inches to the rim) meets ADA guidelines, making this a practical choice for aging-in-place scenarios or households with users who find standard 15-inch bowls uncomfortable. The elongated bowl adds about 2 inches of seating length compared to round models. See our best comfort height toilets guide for a full comparison of ADA-compliant options at similar performance levels.

The American Standard Cadet 3 delivers a verified MaP score of 1,000 grams and WaterSense-certified 1.28 GPF performance at one of the lowest price points in this category, making it the clear value recommendation.

American Standard's EverClean surface treatment uses a silver-based antimicrobial glaze that inhibits bacterial and mold growth between cleanings. The PowerWash rim design pushes water forcefully along the bowl walls rather than through standard rim holes, contributing to the strong MaP result. The Cadet 3 is available in right-height (approximately 16.5 inches) for ADA compliance and in standard height where lower seating is preferred.

For landlords and property managers, the 5-year limited warranty combined with a 1,000-gram MaP score makes the Cadet 3 a low-maintenance investment. American Standard spare parts -- fill valves, flappers, flush valves -- are widely stocked at hardware chains, reducing repair lead times. See our best toilets for rental properties breakdown for additional context on durability-focused options.

The TOTO UltraMax II brings the same 1,000-gram MaP performance and Double Cyclone flush technology as the Drake II into a seamless one-piece body that is easier to clean and visually cleaner than two-piece alternatives.

One-piece toilets eliminate the rubber gasket that connects tank to bowl in two-piece designs -- that gasket is a common source of slow leaks over time. The UltraMax II's single vitreous china body is also substantially easier to wipe down because there are no crevices between components. TOTO's CeFiONtect ceramic glaze, available on several UltraMax II trim levels, creates an ion-barrier surface that resists biofilm adhesion more effectively than uncoated vitreous china.

Owner reviews frequently highlight the quiet flush as a standout feature. The Double Cyclone's water delivery through two nozzles distributes energy more evenly than a single-jet or rim-hole design, which produces less turbulence noise while still generating the velocity needed for the 1,000-gram MaP result.

The Kohler Cimarron K-6418 achieves a MaP score of 1,000 grams using Kohler's AquaPiston canister flush valve, delivers 1.28 GPF WaterSense performance, and is backed by Kohler's wide parts availability and dealer network.

Kohler's AquaPiston technology replaces the traditional flapper with a canister valve that opens along its entire 360-degree circumference, allowing more water to enter the bowl simultaneously compared to a hinged flapper that opens from one side only. The result is a more forceful initial water delivery that contributes to the 1,000-gram MaP result. The Cimarron is also available in Kohler's elongated Comfort Height configuration, matching the ADA-friendly bowl height standard.

One practical advantage the Cimarron has over TOTO is parts availability. Kohler's AquaPiston canisters, tower seals, and fill valves are stocked at major home improvement retailers in most US markets. TOTO replacement parts are more often special-order items in smaller markets. For owners who prefer to handle minor repairs themselves, this difference is meaningful.

The American Standard Champion 4 uses a massive 4-inch flush valve and 2-3/8 inch fully glazed trapway to achieve a MaP score of 1,000 grams at 1.6 GPF -- a higher water volume than WaterSense models but with trapway geometry that is genuinely difficult to clog.

The 4-inch flush valve on the Champion 4 is approximately 77 percent larger in opening area than a standard 2.25-inch valve. This allows the tank to empty more rapidly, delivering a concentrated surge of water through the 2-3/8 inch glazed trapway. American Standard markets the Champion 4 as capable of flushing a bucket of golf balls -- while that is a marketing claim rather than a certification, the underlying hydraulics that enable it also explain the consistent 1,000-gram MaP results.

The trade-off is water use. At 1.6 GPF compared to 1.28 GPF WaterSense alternatives, the Champion 4 uses an additional 0.32 gallons per flush. In a household averaging 5 flushes per day per person, a family of 4 would use an extra 2,336 gallons per year compared to a WaterSense 1.28 GPF toilet. This is a real cost worth acknowledging, though for households that have spent years dealing with clogged toilets and plumber calls, the math may still favor the Champion 4.

Gerber's Viper 21-302 is an often-overlooked performer that scores 1,000 grams in MaP testing with a 1.28 GPF WaterSense-certified flush, typically at a price well below the TOTO and Kohler entries in this list.

Gerber is a professional-trade brand with strong market penetration through plumbing supply houses rather than big-box retailers, which is why it is underrepresented in consumer reviews despite solid MaP performance. The Viper's 3-inch tower flush valve and fully glazed trapway produce the same 1,000-gram result as more expensive models using conventional gravity-flush mechanics. Owner reviews where available are consistently positive for flush reliability and water efficiency.

The Viper is a particularly strong recommendation for contractors installing multiple units in apartment renovations or new construction, where cost per unit is a significant factor and MaP-verified performance is still required by building standards in many municipalities.

The Woodbridge T-0001 is a skirted one-piece toilet with a published MaP score of 800 grams, 1.28 GPF WaterSense certification, and a fully concealed trapway that gives it a clean-line appearance at a mid-range price well below TOTO one-piece models.

The Woodbridge T-0001 occupies an interesting position: it is not the most powerful toilet on this list, but its skirted one-piece body makes it one of the most maintainable from a cleaning standpoint. The concealed trapway eliminates the exterior grooves and curves of a standard exposed trapway where mineral deposits and biofilm accumulate. For buyers who spend significant time cleaning bathrooms, this functional benefit has real-world value.

At 800 grams MaP, the T-0001 sits at the floor of this list's qualification threshold. In practical terms, 800 grams means the toilet handles normal household solid waste reliably. Issues would only arise under exceptionally heavy loads. For a one or two person household or a guest bathroom, 800 grams is more than adequate.

Swiss Madison's Ivy SM-1T257 offers a refined square-influenced bowl profile, MaP-verified 800-gram performance, and a 1.28 GPF WaterSense flush at a price point accessible to design-forward buyers who do not want to pay for premium Japanese engineering.

Swiss Madison has built a following among homeowners completing design-led bathroom renovations who find standard white vitreous china too generic. The Ivy's elongated bowl and clean slab profile fit well with frameless glass showers and floating vanities. Matte white finish options are nearly unique in this category among gravity-flush toilets at this price tier.

The 800-gram MaP score positions the Ivy appropriately for guest bathrooms and powder rooms where flush loads are lighter and the visual impression of the fixture is more prominent than in a primary household bathroom. For high-traffic family baths, the Woodbridge T-0001 or any of the 1,000-gram options above would be a stronger fit.
