The Number One cause of returned bidet seats is incorrect toilet seat size (shape). Basically toilets come in two shapes, round or elongated (oval). Generally if the distance from the bolts that hold the seat to the bowl to the front of the bowl is around 16 1/2 inches, the bowl is ROUND. If the distance is closer to 18 1/2 inches, the bowl is ELONGATED.
When you look at the picture here, it seems obvious which is which, but in the real world, it’s not always so easy to tell.
Grab a tape measure and do a quick check. Measure from the center of the bolts that hold the toilet seat to the outer, front edge of the bowl. NOTE: do not measure your existing SEAT, you need to measure the porcelain bowl. We found this video that lays out just how to do this very nicely.
The bottom line (pun intended) is no matter what shape toilet you have, we can fit it. All of our seats come in round or elongated sizes. If you have any questions please feel free to call us toll free at 888-670-9389
