How We Rate Toilets
The exact criteria and weighting behind every score and ranking on this site.
Each toilet earns an overall rating built from five weighted criteria. We score every model on the same scale so our comparisons are consistent and fair.
| Criteria | Weight | What we look at |
|---|---|---|
| Flush Power | 30% | MaP flush-test score, flush system, flush valve size |
| Clog Resistance | 25% | Trapway width, glaze, owner-reported clog rate |
| Water Efficiency | 20% | GPF, EPA WaterSense, dual-flush options |
| Value | 15% | Features and durability relative to typical cost tier |
| Reliability | 10% | Brand track record, warranty, parts availability |
Why we weight flush power highest
A toilet exists to clear the bowl cleanly in one flush, so flush power and clog resistance together make up 55 percent of every score. A toilet that looks good but needs a second flush fails the one job that matters most.
How the final score is set
We combine the five weighted criteria into a single rating from 0 to 5. The badges you see (Best Overall, Best Power, Best Budget and so on) reflect where each toilet leads its category, not just its raw score.
If you only compare one specification across models, compare the MaP score. It is the clearest single predictor of a strong, reliable flush.
