Standard fixtures: the bolt holes of your existing toilet must be between 5¼–8” apart. You will also need at least ¾” clearance from the center of the bolt holes to the back of your toilet tank.
French curve toilets: to ensure the attachment will fit your toilet, please follow these steps.
- Measure 2¼” in a straight line from the center of either bolt hole to the edge of the toilet fixture (shown as “A” in the diagram above.)
- Measure from Point “A” (established in the step above) towards the toilet tank. You will need at least ¾” of clearance (shown as “B” in the diagram below) for the attachment to fit on your toilet.
