Research updated June 2026.
Quick Answer
For a two-person home, the TOTO Drake II 1G stands out for its unmatched 1000g MaP score, 1.0 GPF efficiency, and quiet dual-flush performance. If budget is a priority, the American Standard Champion 4 offers a 2-3/8-inch trapway and proven clog resistance at a lower cost. Both models are WaterSense certified and sized for a standard bathroom.
What Makes a Toilet Ideal for a Two Person Home?
A two-person household typically generates moderate daily use, so the ideal toilet balances strong flushing power with water conservation. Models with a MaP score of at least 600g ensure reliable waste removal, while a 1.0 to 1.28 GPF rating keeps water bills low. Comfort height and a quiet flush are also important for shared bathrooms.
Expert Take
Small households often overlook trapway diameter. A 2-1/8 inch trapway (common in budget models) clogs more easily with paper volume. For two people, a 2-3/8 inch or larger trapway like the Champion 4's 4-inch flush valve provides a much better experience.
How Do MaP Scores Affect Performance for Two People?
MaP (Maximum Performance) scores measure the mass of waste a toilet can flush in a single cycle. For a two-person home, a minimum MaP score of 600g is recommended to handle occasional heavy loads. Scores above 800g, like those from TOTO and American Standard, provide a significant margin of safety against clogs.

Best Overall
TOTO Drake II 1G (CST454CEFG)
The TOTO Drake II 1G delivers the highest MaP score in its class while using only 1.0 GPF, making it the smartest choice for a two-person home.
Flush TypeDual flush (1.0/0.9 GPF)
GPF1.0 / 0.9
MaP Score1000g
Trapway2-1/8 in
Height16-1/8 in
WarrantyLifetime
- Exceptional 1000g MaP score
- Ultra-low 1.0 GPF saves water
- Quiet, powerful dual flush
- Lifetime warranty
- Higher upfront cost
- Requires specific TOTO bowl
- Not ideal for very tall users
Owner reviews consistently praise the Drake II for its quiet, powerful flush that rarely requires a second attempt. The 1.0 GPF setting handles typical two-person household waste easily, while the 0.9 GPF option is sufficient for liquid waste. Some users note the seat height is slightly lower than comfort height models, but most find it comfortable for daily use.
The TOTO Drake II uses the company's Tornado Flush system, which spins water through two nozzles to clean the bowl without siphoning. This design reduces noise and prevents clogging. The 2-1/8 inch trapway is standard, but the 1000g MaP score proves the flush is powerful enough to compensate.
Expert Take

The Drake II 1G is the most water-efficient toilet that still achieves a perfect MaP score. For a two-person home, this means lower water bills without sacrificing performance. The dual flush adds flexibility for different waste types.
Bottom Line: The TOTO Drake II 1G is the top performer for two-person homes, offering unmatched efficiency and flushing power.
American Standard Champion 4 (246AA)
The Champion 4 matches the Drake II's 1000g MaP score at a lower price, thanks to its massive 2-3/8-inch trapway that resists clogs.
Flush TypeSingle flush
GPF1.28
MaP Score1000g
Trapway2-3/8-inch fully glazed
Height16-1/2 in
WarrantyLifetime
- 2-3/8-inch trapway prevents clogs
- 1000g MaP score
- Affordable price point
- Lifetime warranty
- Single flush only
- Slightly louder flush
- Not as water-efficient as 1.0 GPF
The Champion 4 uses a 4-inch flush valve and a 2-3/8-inch trapway, the largest in its class. This design allows waste and paper to pass through easily, reducing the risk of clogs. Owner reviews highlight its reliability even with heavy use, though some note the single flush is louder than dual-flush alternatives.
At 1.28 GPF, the Champion 4 is WaterSense certified and uses slightly more water than the Drake II, but the trade-off is a simpler, more robust flushing mechanism. For a two-person home, the difference in water cost is minimal, and the lower purchase price makes it an attractive option.
