plumbing question

[Airbrush art]

The bathroom toilet rocks on the floor, the flange bolts are not broken and are as tight as possible, I'm thinking I need to replace the wax seal and replace the flange bolts, any thing else I need to check?

[Paté]

Maybe the flange is too high? Has it always been loose? You could shim it and seal around the perimeter.

Floor is not level flange is too high. Shims under edge or go old school plaster

i had a toilet a little two high. put double stacked nickels at 12 3 6 9 oclocks. then plaster if paris aeound the seam

Need to make sure your closet flange hasn't sheared off of the waste pipe. That can make the toilet rock too. Ask me how I know. Depending on how old the set up is, it could be lead.

The flange is supposed to be screwed to the floor so its solid then the wax and bowl bolts... once reset on the secured flange you should use plaster or sanded floor grout to fill it in and sure it up. You can caulk around it after to seal the plaster or grout

I use sanded floor grout, and set the bowl into the grout. It will never rock for life.

Pull the toilet check to see if the flange is broken or not securely connected to the floor. If the flange is broken pick up a repair fla be and a deep cone wax ring. Set the toilet in a sanded grout bed, wipe away the excess and you are back to pooping without the rocking.

I just did this in my master bath. Toilet rocked pretty bad when you sat on it. Pulled it off, cleaned everything up, and when I when to test fit it back down, it sat flat and didnt wobble. I did have to cut a loose flange bolt off so I think maybe there was the problem. there was also one tile that was a little lower so instead of plastering the whole thing, I put a couple of shims in, and then caulked the whole thing around. Rock solid now.

Bad advice!
More fiber. So it comes out easier and he stops rocking back and forth to get that last piece!

As to really answering the OP's question, as others have said,
Make sure flange is secure to floor. use shims or plaster if necessary.
Grout is not strong enough.
I like Durabound 90 better than plaster.
it's basically plaster with glues and hardeners in it so it's tougher than plaster.
If using plaster I'd use patching plaster.

Durabound 90 is in the sheetrock supply aisle of Homer Depot. Anbouut $10 a bag. You mix it just like plaster.
The 90 you have about 90 minutes to work with it, hence the name

I typically would recommend not sealing around the entire bowl. I like to leave at the least the back unsealed just in case there is a leak down the road, you know about it before it rots the structure and leaks to the floor below if there is one. Basement or toilet on a slab, by all means, seal it up.

That's what most plumbers will tell you. Also don't put a band aid on it, pull the toilet and find the real problem.

OK problem solved, after removing the toilet I found the flange was loose , removed all the screws replaced everything flange mounting screws, flange bolts & seal, everything is nice and tight no more rocking around. Thanks everybody for your input.
