What should I do with my wobbly toilet?

It don't matter if the ring is put on the flange or the toilet. To me, it sounds like the flange is to high. The only way to fix this now, is to shim it. Buy some tapered shims, and apply an adhesive silicone to both sides. tap the shims in place around the base of the toilet. After the silicone dries, you can trim them. Then put a continuous bead of silicone around the base to fill in any gaps.

Ok suellenh has the right idea but the wrong method...lol IF it is just a case of loose bolt that need tightening and after tightening the plastic caps won't snap back down bc the bolt is to high.Then you need to cut the bolt short enough with a hack saw for allow it to snap back on.

However I don't think its just a matter of loose bolts from your descirption. And i dont think it's what wing1500 says either however its a valid solution that's worth looking into.

IMHO the problem is that when he put down the new floor He failed to make it level where the toilet sets.Hence the need for the shim under it.

So You can either put the shim back & caulk the gap(not the best solution if the gap is at the front of the toilet where its going to show.

The other unfortunately is remove the toilet, tear up the tile, and make it right as he should have done in the first place!!!

My question to you is, is the bottom of the flange sitting tight on the linoleum or is it elevated some? If it's tight to the floor, the toilet should seat. If the floor is out of level, sometimes placing a shim or 2 as required will fix that. If the flange is elevated some, do this; cut the flange off flush with the floor with a sawzall. Go to Home Depot in the plumbing section where the flanges are. There is one type that slides right inside the pipe. It has a rubber gasket on the outside. You just push it in. I would also drill and put anchors into the slab at screw mounting holes in the flange. Do this before you set the flange. Another option is to just remove the linoleum and tile the floor and that takes care of the problem. The issue with placing plywood, is it will look shabby, or you will have a large amounts of caulk to hide the plywood, and that looks shabby too. caulk

If he took up the old floor and put down an underlayment then the tiles. And if the floor he took out was thicker then what he put back.

The floor toilet plumbing flange is to high and not allowing the toilet to sit on the new floor properly.

If that's the case the toilet will have to be removed and the floor flange lowered to it correct height. then the toilet installed.

Th guy did not do it right.

Ether way with the wax gasket is fine.

Wobbly toilets are unsettling to sit on and can eventually leak from the wax ring. So, on each side of the toilet base is a bolt that is covered with a little plastic bubble. These are generally applied with a glob of caulk, which is supposed to hold them on forever; however, nothing is forever and they'll eventually pop off. However, you can use a knife blade or a thin screw driver blade to pop both of these off so you can tighten the bolts. Tighten them gently as toilets are ceramic or something and can be broken or cracked. When both bolts are tightened so the toilet isn't wobbly any longer, dig out most of the caulk and put a bit more inside the bubble, then smash it onto the bolt and let it dry in place. If removing these bubbles ruined them, take one to the hardware store and buy some new ones.
