We compare published specs, MaP flush-test scores, certifications and aggregated owner reviews. We do not physically test units in a lab. Our goal is to surface the data that actually predicts a strong, clean, reliable flush, then present it clearly.
MaP (Maximum Performance) is an independent flush test measured in grams of solid waste cleared in a single flush. A score of 1000 grams is the top tier most premium toilets aim for; 600 to 800 grams is still a strong, reliable flush for typical household use. We list the exact MaP score for every toilet we rank, sourced from the same published test data, so the numbers stay consistent across every page on this site.
Rough-in is the distance from the wall behind the toilet to the center of the floor drain bolts, and it is the single most common return reason. Most homes use a 12-inch rough-in, but 10-inch and 14-inch exist too. Measure yours before ordering; the wrong rough-in means the toilet will not sit against the wall correctly.
A strong flush combines bowl design, a wide glazed trapway and an efficient flush valve. A high MaP score signals it can clear more waste in a single flush with less water.
MaP (Maximum Performance) is an independent flush test measured in grams of waste cleared in one flush. Higher is better. Scores of 800 to 1000 grams indicate a very strong flush.
For many homes, yes. A dual-flush lets you use a lighter flush for liquid waste, which can meaningfully lower water use over a year while keeping full power available when needed.
Rough-in is the distance from the wall to the center of the floor drain bolts. Measure it before buying; 12-inch is standard, but 10-inch and 14-inch models exist for non-standard bathrooms.
Comfort-height (ADA height) bowls sit about 17 to 19 inches tall, closer to standard chair height, which makes sitting and standing easier for taller adults, older adults and anyone with joint or mobility concerns.
