If your toilet wobbles, the solution is easier than you might imagine. As you can see in the Illustration, the toilet sits on a flange that’s connected to the drain pipe. Bolts attached to the flange pass through the holes in the toilet base.
If the nuts are loose, tighten them by hand, and then use a small wrench to snug them about a quarter-turn beyond hand tight. Don’t overtighten the nuts, or you can crack the toilet base and create a bigger problem.
If tightening the nuts doesn’t stop the wobble, then pick up plastic toilet shims, which are available in the plumbing department. Slip a shim in under each side of the toilet, preferably near the back of the toilet, so they won’t show. Don’t force the shims under the toilet. Just push them under gently. Then retighten the mounting nuts. Once the toilet is secured, cut off any excess shim material using a utility knife.
Have a nice weekend,
