Your Toilet Shouldn’t Wobble (And Other Things I Say for a Living)
Loose toilets are one thing I write up a lot. Almost every house has at least one, and almost every homeowner already knows about it. They’ve felt it shift when they sit down and just decided to live with it. (Sometimes with a little heart attack thinking the toilet is about to break beneath you!)
I get it. I’m still going to rock it. I straddle the toilet, grab both sides with my legs, and push. If it moves, it goes in the report. I do this in every house, and it’s every bit as weird as it sounds when you’re standing in someone’s bathroom watching me do it.
Ok, so why do inspectors check? Your toilet sits on a wax ring that seals it to the drain. When the toilet wobbles, that seal breaks down, and every flush can push a little water out the bottom. Not enough to see, just enough to slowly soak the floor underneath. By the time anyone notices, the subfloor is soft and you’re paying for a lot more than a wax ring. It can also let sewer smell into the bathroom, so if you’ve ever wondered about that, there you go.
The cause is usually boring. The bolts at the base worked loose. Or someone put in new flooring and never reset the toilet. Or it was never installed right and has been wobbling since 1998.
You can check yours in about ten seconds. Stand over it and try to rock it side to side. It shouldn’t budge.
If it does, pop the little caps off the base and you’ll see two bolts. Snug them up a bit at a time, switching sides, the way you’d tighten lug nuts on a tire. Don’t go full gorilla on them. Porcelain cracks, and then you’re shopping for a new toilet.
If it’s still loose after that, the wax ring probably needs replacing. That’s a doable DIY job or a quick visit from a plumber. But if the floor around it feels soft or spongy, there are stains, or the base is damp, stop and call someone. At that point it’s not about the toilet anymore.
If you’re buying and this is in my report, don’t freak out. It’s usually a cheap fix. If you’re selling, tighten it up before the inspection. It takes five minutes and it’s one less thing on the list.
