What to Do If the Toilet Flange Is Too High

There is one exception: waxless sealing rings may be able to bridge the gap between the floor and toilet for you. This product also has a higher risk of leaking.

Option #1: Raising the Floor

Tile is an effective way to raise the floor around your toilet, especially if it is set on concrete or vinyl. Depending on the amount of height that is required, backing board could be placed underneath the tile to provide the amount of support that is required.

For small height problems, something as simple as grout and be added around the toilet to help secure it and prevent it from leaking. If you use this method, make sure that you have the weight of the toilet supported where it is off the floor so the grout will harden in a supportive way.

You can also build risers with the flooring materials you used, such as a hardwood flooring option, to allow the toilet to sit properly.

Option #2: Cutting the Pipe

Cutting the top of the pipe should be your last option, but it may be the only option you have. Many pipes use PVC, so a simple cable saw outfitted with a proper blade can do the cutting. You will need to remove the flange first, which means you’ll need to replace it once you’ve finished with this job.

Cut it so that your pipe is flush with the floor. Many floors are not properly square, so you’ll need to check what the angle of the floor happens to be to create the flush cut.

Then attach the new flange.

If your toilet flange is too high, do not use the toilet until you’ve corrected the problem. These fixes may not be simple, but they can get the job done for far cheaper than alternative repair methods.
