1. What do you actually do to evaluate a toilet?

For each toilet we cover, we synthesize three categories of evidence:

• Manufacturer specifications — the canonical source for dimensions, GPF, rough-in, materials, and certifications. We read the official PDF spec sheet, not the retail listing.
• Independent testing data — primarily MaP (Maximum Performance) toilet testing results, Consumer Reports lab data, EPA WaterSense database listings, and CSA certification records.
• Verified owner sentiment — aggregated reviews 12 months post-purchase, filtered for reliability issues that only emerge after a year. We weight the second-year reviews more than first-week reviews because that’s when flush valves and flappers start failing.

Where we have hands-on experience with a unit, we say so explicitly. Where we don’t, we tell you what our recommendation is based on.

2. What criteria do you judge against?

Every recommendation is judged against the same eight criteria:

1. Flush performance — MaP score, real-world clogging incidents, single-flush solid-waste handling
2. Water efficiency — GPF, WaterSense certification, real consumption (often differs from rated GPF)
3. Bowl shape and seat height — fit for the intended buyer (small bathroom, accessibility, family with kids, tall adults)
4. Build quality — vitreous china thickness, trapway glazing, hardware corrosion-resistance, manufacturer track record
5. Installation difficulty — rough-in compatibility, weight, completeness of the box (seat? supply line? wax ring?)
6. Warranty and parts availability — length of warranty, whether replacement flappers and fill valves are findable five years later
7. Total cost of ownership — purchase price plus realistic install cost plus expected ten-year maintenance
8. Verified owner sentiment — long-term reliability from owners who have lived with it for 12+ months

3. What do you NOT do?

We are not a lab. We do not install every toilet we review in a controlled environment with calibrated equipment. When we make a recommendation, it is the result of synthesizing the sources above against the eight criteria above — not a claim that we have personally flushed 2,000 ping-pong balls down each unit. We do not currently buy our own copies of every product (that would cost ten thousand dollars per round-up and we are not Consumer Reports yet).

What we do have is a tightly held standard for what makes a recommendation: nothing goes into a “best of” list unless we would tell a friend to buy it. The number of recommendations in any guide is whatever passes that bar — not a fixed number padded to look comprehensive.

4. How do you handle conflicts of interest?

We earn affiliate commissions when readers buy through our links to retailers like Home Depot, Lowe’s, Build.com, Wayfair, TUSHY, and others. These commissions never change what we recommend. We have on multiple occasions chosen to feature products from retailers that pay us lower commissions than competitors, because they were the right answer for the buyer.

If a brand pays us for a sponsored article, it is clearly labeled Sponsored at the top and the bottom of the article, and we tell you what was paid for what. We do not accept payment in exchange for positive reviews. Sponsored content has never appeared on this site as of this writing.

5. What happens when you get it wrong?

We fix it on the original page, add a corrections note at the bottom of the article, and update the “Last updated” date at the top. If the error materially changed the recommendation, we say so explicitly. Email us at hello@mybesttoilet.com if you spot one.
