Will a Bidet Fit My Toilet?

How Can I Tell If My Toilet Is A One-Piece Or Two-Piece Toilet?

I’m happy to hear that you are ready to take the next step.  By using a Bidet, you will experience a cleaner and healthy feeling.  As you can see in the photo below, there are two types of toilets: one-piece where the tank is part of the bowl and two-piece where the tank is separate from the bowl but attached with bolts. You can also download the printable PDF of this page so you can have it with you when checking your toilet, here is the link Will a Bidet Fit my Toilet

Will A Bidet Fit My One Or Two-Piece Toilet?

If you have a two-piece toilet, good news… the short answer is yes.  It will fit most standard two-piece toilets. There are a few exceptions, so please check the measurements below to make sure the area around the bolt holes which hold the toilet seat are flat and level.

If you have a one-piece toilet, your options are more limited. For example, the one-piece toilet above could be a Kohler San Raphael Elongated Toilet or the Rialto Round Toilet (they look the same but one has a round seat and other has a elongated seat). The COCO 6035R Bidet, Coway BA13 Bidet and the Clean Sense DIB-1500R Bidet will fit these two toilets but not some of the older ones. Make sure you check the measurements regardless of what toilet you have and please call me if you have any concerns about your one-piece or two-piece toilet.

How Can I Tell If My Toilet Is Round Or Elongated?

Above are actual photos of an elongated and round toilets, You think it should be easy to tell the difference, but not always.  I sometimes have customers call me thinking that their “round” toilet is actually elongated and the best way to tell is always by measuring them.

If line C is 16.5 inches or 42cm, you have a round toilet, like the one on the right.

If line C is 18.5 inches or 47cm, your toilet is elongated, like the one on the left.

To determine line C you will need to measure from the center of the two bolt holes to the outside front of the toilet bowl. If the measurement turns out to be about 17 ¾" or 45cm , your best fit would be an elongated Bidet.  If the dimension is different for your toilet, you can always call me and it would be delighted to help you.

Line B should be 5.5 inches or 14cm, center to center of the bolt holes and most Bidets will accommodate up to 7.5 inches or 19cm.

For line A, that is the distance from the center of the bolt holes to the tank. In most cases, you will need 1.5 inches or 3.8cm for the Bidet Toilet Seat to fit. This area should be flat and not have any curvature or sloping up. Most two-piece toilets will have 3 to 4 inches or 7.6cm to 10cm, while some one-piece toilets will have less than 1.5 inches or 3.8cm. If your dimension is smaller than 1.5 or 3.8cm inches, please call me.

If you have any questions and need help determining if your toilet will accommodate a Bidet Seat, please contact me.  I love talking to my customers and enjoy helping you get the Bidet which will best suit you needs.
