WASHLET BIDET SEATS FIT MOST NORTH AMERICAN TOILETS. SEE IF IT FITS YOURS.

Good news! WASHLETs will fit most standard North American toilets. To see if a WASHLET will fit on your toilet, follow these simple steps:

First, determine if you have an elongated or round-front toilet. An elongated toilet’s bowl is 18.5 inches from the mounting holes to the front of the bowl, while a round front is 16.5 inches.

You need an elongated style WASHLET for an elongated bowl and a round-front WASHLET for a round-front bowl.

Next, for an elongated toilet, you need at least 2-1/2 inches of space from the toilet tank’s front to the mounting holes’ center for a WASHLET to fit correctly. On a round-front toilet, you need at least 2-1/2 inches for a WASHLET C5 or C2 and at least 1-3/4 inches for the WASHLET S550e and S500e.

Please note, if you have a French-curve toilet, it may prevent WASHLET installation. Check to make sure you have adequate space across the width of the tank so that a WASHLET will fit correctly.

Next, measure the distance between the mounting holes. You need approximately 5-1/2 inches from the centers of the seat mounting holes.

You will need a minimum of 8 inches of open space from the toilet’s center to the edge of the bowl’s flat surface.

Finally, remember, you need a GFCI outlet within 3 feet of the toilet.
