Four answers, one straight verdict. Tell the checker what you measured — bolt holes to front edge, bolt spread, toilet style, and outlet distance — and it will tell you which seat shape to buy, which problems to expect, and whether an electric seat is even on the table. Not sure how to measure? The fit guide walks through each one.
How the checker decides
It uses the same four checks as the fit guide: bowl shape from the bolt-to-front measurement, the 5.5-inch bolt standard, whether the seat’s back can sit flat (the French-curve problem), and whether a GFCI outlet is within a roughly 4-foot cord. Any one of the four can change the verdict — that’s the point of checking before you buy.
Three picks that cover most verdicts
Whichever way your answers landed, one of these three is the usual starting point — the full scoring is in our electric bidet seats comparison.
LUXE Bidet NEO 120
The no-outlet answer: a non-electric attachment that fits nearly any two-piece toilet and needs nothing but the water line.
Alpha JX2
The one-piece answer: a slim, low body that sits flat on some French-curve toilets the other seats rock on — 87/100 in our comparison.
Bio Bidet BB-2000 Bliss
The standard-fit answer: our top pick at 88/100 — the strongest wash in the group and a full 3-year warranty, if your measurements give it room.
