Toilet Flange is Crooked

I built a new house that is a slab on grade with no basement. All the 4 inch plumbing is in the concrete. When I set the toilet flange it some how got moved or I didn't set it level. So after the concrete was finished I noticed that one end of the flange is sticking up 3/8 of an inch off the concrete,while the other end is sitting on the concrete. What can I do to not make my toilet wabble and yet be secure, if anything? THANK YOU!

Toilet Flange not level

I have a toilet flange that is not flush with the concrete. It is a pvc flange and sticks up about 3/8 of an inch one one side causing the toilet to not sit level and want to wabble. What can I do. Thanks.

I would trim the plastic flange with a saw.

If you need something to hold the bolts down, you can always use a repair flange rotohammered into the concrete.

You could either shim it on the other side or replace the flange.

The problem did not occur when you installed the flange, it happened when the pipe was installed, because it was not vertical.
