Review updated June 2026.
Quick Verdict
The TOTO Drake Two-Piece is the best overall flushing toilet for most homes because of its proven 1000g MaP flush power, reliable G-Max siphon jet system, and universal height design. It is not the cheapest option and does not include a seat, but its consistent performance across millions of installations makes it a safe, long-term choice.
The TOTO Drake Two-Piece flush is exceptionally powerful, earning a MaP score of 1000g. This means it can clear 1000 grams of solid waste in a single flush, which is the highest possible score in the MaP testing program and indicates outstanding performance for a 1.28 GPF toilet.
The MaP (Maximum Performance) score is the industry standard for measuring toilet flush effectiveness. A score of 1000g means the TOTO Drake can handle the heaviest waste loads without clogging. The G-Max siphon jet system uses a 3-inch fully glazed trapway, which is wider than standard 2-inch trapways. This wider passage allows waste to pass through more easily while the glazed surface reduces friction. The siphon jet action creates a strong suction that pulls waste out of the bowl rather than pushing it, resulting in a clean bowl with minimal streaks. Owners consistently report that the Drake rarely requires a second flush, even with large waste volumes. The flush is also relatively quiet compared to pressure-assisted toilets, making it suitable for bathrooms near bedrooms.
Editorial Take
The 1000g MaP score combined with the 3-inch glazed trapway makes the TOTO Drake one of the most reliable performers on the market. It delivers commercial-grade flush power in a residential package.
How water-efficient is the TOTO Drake Two-Piece?
The TOTO Drake Two-Piece uses 1.28 gallons per flush (GPF), which is 20 percent less water than the federal standard of 1.6 GPF. It is WaterSense certified, meaning it meets EPA criteria for both water efficiency and performance.
Using 1.28 GPF saves approximately 2,900 gallons of water per year for an average household compared to older 3.5 GPF toilets. The WaterSense label requires toilets to pass a rigorous flush test that simulates real-world use, so efficiency does not come at the cost of performance. The Drake achieves this low water consumption without using dual-flush technology, relying instead on the optimized G-Max siphon jet design. Some owners note that the 1.28 GPF flush can leave light residue on the bowl occasionally, but this is typical for low-flow toilets and does not affect waste removal. The absence of CEFIONTECT (TOTO's glaze technology) on this model means the bowl may require more frequent cleaning than higher-end TOTO models, but the basic vitreous china surface is still durable and easy to wipe down.
Editorial Take
The 1.28 GPF water usage is excellent for a toilet with a 1000g MaP score. Many toilets with similar water savings struggle to clear 600g, so the Drake's efficiency-to-power ratio is outstanding.
What do owners say about the TOTO Drake Two-Piece?
Owners consistently praise the TOTO Drake Two-Piece for its reliable flush power, easy installation, and comfortable universal height. Common complaints include the lack of a seat, the plain aesthetic, and occasional reports of bowl residue.
Aggregated reviews from major retailers show an average rating of 4.5 out of 5 stars across thousands of reviews. The most frequent positive themes are the flush power (owners often say "it flushes everything in one go"), the quiet operation, and the ease of cleaning due to the smooth bowl design. Many owners appreciate that the two-piece design is lighter and easier to maneuver through doorways and up stairs compared to one-piece toilets. The universal height (16.5 inches) is frequently mentioned as comfortable for both tall and average-sized adults. Negative feedback focuses on the seat not being included (owners must purchase separately), the basic appearance lacking modern styling, and occasional reports of the flush leaving light marks on the bowl. A small number of owners mention that the fill valve can be noisy after a few years, but replacement parts are widely available and inexpensive. Overall, the Drake has a reputation as a "set it and forget it" toilet that performs reliably for decades.
Editorial Take
Owner feedback confirms the Drake's reputation as a low-maintenance workhorse. The most common complaints are minor and easily addressed, while the flush performance is universally praised.
How does the TOTO Drake Two-Piece compare to similar toilets?
Compared to the American Standard Champion 4, the TOTO Drake matches its MaP score (both 1000g) but uses less water (1.28 GPF vs 1.6 GPF). The Champion 4 includes a seat and sits at a similar 16.5-inch chair height, but the Drake offers better water efficiency for the same flush power.
The TOTO Drake and American Standard Champion 4 are both popular two-piece toilets designed for heavy use, and both post a perfect 1000g MaP score. The Drake's G-Max system uses a wider 3-inch trapway, compared to the Champion 4's narrower 2-3/8-inch trapway, though the Champion 4 compensates with a 4-inch flush valve that empties the tank in a faster surge. The Champion 4 uses 1.6 GPF, which is 25 percent more water per flush, making it less efficient. However, the Champion 4 includes a seat and sits at a comparable chair height (16.5 in) to the Drake's universal height. The Champion 4 also has a limited lifetime warranty compared to the Drake's 1-year warranty, which is a meaningful difference. In terms of price, the Drake is typically more expensive than the Champion 4, but many buyers prefer its lower water use for the same flush power. For those prioritizing water efficiency, the Drake is the better choice. For those wanting a seat included, a longer warranty, and the widest possible flush valve, the Champion 4 is worth considering.
Editorial Take
The TOTO Drake and American Standard Champion 4 are tied at a perfect 1000g MaP score, so this comparison comes down to water use and extras, not flush power. The Drake wins on water efficiency, while the Champion 4 offers better value with its included seat and longer warranty. Choose based on your priorities.

Is This Toilet Right For You?
Best for: Households that want proven, no-frills flush power at a mid-range price, including larger families and anyone replacing an older toilet that clogs often.
Avoid if: You want CEFIONTECT-style stain resistance or the newer Double Cyclone flush, since this is the standard-glaze original Drake rather than the Drake II, and it does not include a seat.
Check before buying: Confirm a 12-inch rough-in, which is standard for most homes, plan to buy a seat separately since none is included, and know that the 16.5-inch universal height suits most adult users.
Why we picked it: A 1000g MaP score on just 1.28 GPF with a 3-inch fully glazed trapway and G-Max siphon jet flush is rare, especially at this price point. As one of TOTO's most widely sold toilets, replacement parts and seats are easy to find at major retailers, though TOTO parts can cost more than mainstream American brands.
Our Verdict
The TOTO Drake Two-Piece is the best overall flushing toilet for most homes. With a 1000g MaP score, 1.28 GPF water efficiency, and proven G-Max flush system, it delivers reliable performance that owners trust for years.
