Toilet wobbly after repair

Was it rocking before the repair?

Did you see any shims when you replaced the seal?

Sounds like an uneven floor and the previous installer used the plastic shim and caulk to hold in place.

I would recheck to make sure the bolts are secure, and shim and caulk the shite out of it. As long as you are certain the new ring is properly in place.

Slide a penny under it, once you fix the wobble. Use a Dap bathroom caulk, the one you wipe clean with a wet towel.

If you didn't do anything to your floor during all this, it's not your floor. Toilet could either be misaligned or there was previously some type of shim underneath that you had that got removed.

Either way, just get some plastic toilet shims and you'll be good.

Put the shims where they do the most good, not protruding, then caulk to hide the shims. Just caulk the sides and the front, leaving the back open.

If you do have to pull the toilet again verify the flange from the floor that stand up the bolts is not cracked.

In addition to using a shim, one trick my plumber uses to help avoid leaks from the toilet ring is that he actually places two new wax rings (one on top of the other) before seating the toilet on top of the ring. You get twice the wax and height of the wax to squish down when you place the toilet. I'm not a plumber but it seemed like a good idea when he told me he was doing that. The toilet is seated nice and solid on the extra wax, and no floor leaks.

Friend,

It sounds most likely like an uneven floor. What does your base look like? We were having a leaky toilet based on a wet spot in the ceiling last year. Our house is quite old.

We called a plumber. Like you, he assumed it was the wax ring, so he replaced it, and caulked around the toilet’s base, charging us $200. The leak persisted.

Mother was upset and was going to call him back, but my thinking was you do not call back a person to finish a job he could not get right the first time. I went to the second floor and took the toilet off its mount. The toilet flange was no longer resting on solid subflooring and was listing. Shims were not going to fix this imbalance. Surely, the plumber saw this uneven situation, but either was too lazy or unimaginative to find a real fix.

Uncertain what to do, I looked in the garage and could find nothing but an old bag of self leveling underlay. After removing the phalange, and prepping the area, I carefully mixed small portions of the underlay in an old Hansen’s snoball cup. I installed in a new phalange, as the old one’s screw hole had cracked, and poured the wet underlay around it in small batches.

Sure enough, that ended up working. We were most disappointed in the lack of insight and industry in the plumber in whom we placed our trust. Even more disappointing to me was that the dried underlay bonded to the sides of my Hansen’s cup, rendering it useless for drinking. Mother says that I am in charge of our plumbing problems from now.

Yours,
