Learn how to fix a rocking toilet on an uneven floor. Get step-by-step instructions on using a plastic wedge and caulk to steady a rocking toilet on an uneven tile floor.
LESLIE: David in Tennessee needs some help with a tiling project. Tell us what’s going on.
DAVID: Yeah, we had new tile put in both bathrooms and the tile is not level.
DAVID: And so when we put the toilets back down they rock a little bit.
DAVID: I went to the home store and they had me put these little plastic wedges in there …
TOM: Yes, mm-hmm.
DAVID: … and that’s not a good answer to the problem. They come out and they – and I really don’t know what to do. I’ve thought about putting two wax seals in there but I don’t really know what else to do.
TOM: Well, that’s probably not going to work either because the wax seal is going to settle down and you’re eventually going to have that movement and, if you do, it’ll break the wax seal. I think you’re on the right track here with those little plastic wedges but what you want to do is actually cut them off and have them slip just under the edge of the toilet and then I want you to caulk  them in place by running a bead of silicone caulk all around the outside. In fact, you can put a little bit of caulk underneath it and over it because it tends to – think of it as sort of gluing them in place, David. And that will hold them there and you’ll be allowed to have a little bit of movement and they won’t come out.
DAVID: OK. Good deal. I appreciate it.
TOM: Well, you’re welcome, David. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
