Snap a photo of your toilet — AI finds your seat
Not sure which toilet seat fits your toilet? Take one photo of it. This free AI tool looks at the bowl, tells you whether it's round or elongated, and shows you three seats that fit — in about 10 seconds.
No measuring tape, no squinting at the hardware-store wall. Bowl shape is the one spec that makes or breaks the fit, and it's exactly what the AI is trained to spot. Once it has your shape, we match it to seats we've already researched in our buying guides — a top-of-the-line pick, a best-value pick, and a budget pick.
Private by design — your photo is analyzed in memory and never stored. And to be straight with you: AI gives a fast best-guess; confirm with a 30-second measurement before you buy.
Skip the photo — pick your shape
Round bowls look circular from above; elongated bowls are oval and stick out about 2 inches more. Pick one and you'll get the same recommendations.
Frequently asked questions
How does the toilet seat scanner work?
You take one photo of your toilet. Your browser shrinks the image, sends it to an AI vision model, and the model reads the bowl's proportions — elongated bowls are oval and about 2 inches longer than they are wide, round bowls look circular. We then match that shape to seats from our buying guides at three price points.
Is my photo saved anywhere?
No. Your photo is analyzed in memory to answer one question — round or elongated — and it is never stored on our servers. We don't keep it, log it, or use it for anything else.
How accurate is the AI?
It's a fast best-guess, and camera angle matters — a photo taken from straight above the open bowl is the most reliable. Treat the result as a strong hint, then confirm with a 30-second measurement before you order: about 16.5 inches from the seat bolts to the front rim means round, about 18.5 inches means elongated.
Will a round seat fit an elongated toilet?
No. An elongated bowl is roughly 2 inches longer than a round one, so the wrong seat either overhangs the rim or leaves bare porcelain exposed at the front. Shape is the one spec you have to get right — the mounting bolt spacing is standard on almost every toilet.
What if I already know my bowl shape?
Skip the photo. Use the Round and Elongated buttons on this page and you'll get the exact same three recommendations, plus the bidet upgrade option.
Why only three seat recommendations per shape?
Because fifty options don't help you decide. We show one top-of-the-line pick, one best-value pick, and one budget pick per shape, pulled from our full research. If you want the longer lists, start with our best toilet seats guide.
