Best Toilets by MaP Score: 1000, 800, and 600 Rankings

The TOTO Drake II is the benchmark that competing brands are measured against, achieving the maximum 1000g MaP score at just 1.28 GPF through TOTO's Double Cyclone flushing system and a full 2 1/8-inch fully glazed trapway.

The TOTO Drake II uses a Double Cyclone flushing mechanism that releases water through two nozzles rather than the rim holes found on traditional toilets. This directs water in a centrifugal pattern that cleans the bowl more thoroughly with each flush. Combined with TOTO's SanaGloss ceramic glaze, the bowl stays cleaner between uses, which aggregated owner reviews consistently highlight as a major practical advantage.

The model is available in Universal Height (roughly 17 inches from floor to seat) making it accessible for a wide range of users including older adults and those with mobility considerations. The elongated bowl version is the most popular, though a round bowl variant exists for smaller bathrooms. TOTO backs this toilet with a one-year warranty on parts and finish.

The American Standard Champion 4 built its reputation on one thing: the industry's largest fully glazed 2-3/8-inch trapway, which combined with a 2 3/8-inch flush valve produces a bulk-clearing flush that earns its 1000g MaP score at 1.6 GPF.

The Champion 4's defining feature is a 2-3/8-inch fully glazed trapway, which is roughly 65% larger than a standard 2-inch trapway. This geometry gives the toilet an exceptional bulk-clearing capacity. The 2 3/8-inch flush valve opens wider and faster than standard valves, creating a powerful rush of water from the outset of each flush. This combination is specifically designed for households where clogging has been a persistent problem.

One trade-off is water consumption: at 1.6 GPF, the Champion 4 uses more water per flush than WaterSense-certified 1.28 GPF models. Over a year of average use, this adds up. Households looking for both power and water savings should consider the Cadet 3 (1.28 GPF, also 1000g MaP) as a more efficient American Standard alternative. See our American Standard vs TOTO comparison for a detailed breakdown.

The TOTO UltraMax II shares the Drake II's Double Cyclone flushing system and 1000g MaP score but wraps it in a seamless one-piece skirted design that eliminates the exposed trapway and makes cleaning dramatically faster.

The UltraMax II is essentially the flagship expression of TOTO's Double Cyclone platform. Because the flushing engine is identical to the Drake II, the performance characteristics are the same: 1000g of verified clearing power at 1.28 gallons per flush. The differentiation is entirely in the housing -- one continuous vitreous china piece means no gap between tank and bowl where bacteria or mineral deposits can accumulate.

TOTO's SanaGloss glaze is an ionized coating that creates a surface so smooth that particles struggle to adhere, which aggregated owner reviews cite as reducing how frequently the bowl needs scrubbing. The UltraMax II is a popular choice for primary bathrooms where aesthetics matter as much as performance.

The American Standard Cadet 3 proves that achieving a 1000g MaP score does not require a premium budget: it pairs a 3-inch flush valve with a 1.28 GPF consumption rate and EPA WaterSense certification, hitting the performance ceiling at a significantly lower price than TOTO equivalents.

The Cadet 3 uses a Speed Connect tank-to-bowl coupling system that American Standard says reduces installation time significantly. The 3-inch flush valve is 125% larger than the standard 2-inch valve, producing a fast, high-volume rush of water. The fully glazed 3-inch trapway allows smooth passage of waste without buildup over time.

Owner reviews consistently praise the Cadet 3 for its combination of affordability and genuine flushing reliability. It is one of the most widely installed toilets in North America and has a deep ecosystem of compatible repair parts, which lowers the lifetime ownership cost. For buyers who want proven 1000g performance without paying TOTO or premium Kohler prices, the Cadet 3 is the most straightforward answer.

The Kohler Cimarron achieves a certified 1000g MaP score using Kohler's AquaPiston canister flush technology, delivering a 360-degree water entry that covers the bowl more evenly than traditional flapper-valve designs at the same 1.28 GPF rate.

Kohler's AquaPiston technology works through a canister-style valve rather than a traditional rubber flapper. The canister lifts to expose a 360-degree opening, allowing water to rush in from all sides rather than from behind the flap. This produces a more even flush profile that covers the entire bowl interior more consistently than a flapper valve at equivalent GPF rates.

The Cimarron is widely available in Kohler's full color range and comes with the brand's one-year limited warranty on vitreous china and flushing mechanism components. For buyers who have existing Kohler fixtures and prefer brand consistency, the Cimarron delivers MaP 1000 performance without requiring a brand switch. Our Kohler vs TOTO comparison covers the broader trade-offs in detail.

The Kohler Highline Classic scores 800g on the MaP test -- strong enough for average family use -- while using just 1.28 GPF and carrying EPA WaterSense certification, making it one of the most widely installed WaterSense toilets in the country.

The Highline Classic uses Kohler's Class Five flushing system, a gravity-feed design optimized around a wide 3-inch trapway and a flush valve engineered to release water rapidly. At 800g, it is well above the 600g minimum threshold and comfortably handles typical family solid waste loads in 3-4 person households.

The Highline is the baseline choice when budget is the primary constraint and 1000g performance is not specifically required. Kohler's national distribution means parts are always available without waiting for online orders, and the simple flapper-valve mechanism is something most homeowners can service themselves.

The Woodbridge T-0001 brings a contemporary skirted one-piece silhouette -- the kind usually associated with premium TOTO or Swiss Madison designs -- to a price point well below those brands, while still achieving a verified 1000g MaP score at 1.28 GPF.

Woodbridge positions the T-0001 as a design-forward alternative for buyers who want the clean lines of a European-style one-piece toilet without the premium price of TOTO or Kohler equivalents. The soft-close seat is included (rather than sold separately), and the skirted base fully conceals the trapway, eliminating the hard-to-reach cleaning areas that frustrate owners of exposed two-piece designs.

The MaP 1000g score is confirmed by published testing data, placing the T-0001 in the same performance tier as the TOTO Drake II and Kohler Cimarron. The practical trade-off is brand maturity: Woodbridge does not yet have the nationwide parts distribution network of the major brands, so repairs may require ordering from the manufacturer. For new-construction bathrooms where long-term serviceability is less of a concern, this is a very strong choice. See also our guide on one-piece vs two-piece toilets for the full comparison.
