Toilet Shims

[Mikesr]

Anyone ever use residential toilet shims in an RV to fix a rocking toilet? It’s a porcelain toilet in a 3 year old travel trailer. Flange is new and mounted with additional screws into the floor and flange bolts are tight. It just rocked and fearful it will break the flange bolts. Any suggestions welcome.
TIA

Toilets have two bolts, one on left and one on right. Is it rocking front to back? First thing I would do is pull the toilet up and check to see that the flange is screwed securely to the floor. Should also check to see if there's something going on with the sub-floor itself.

Toilet bolts tighten the bowl to the flange, not to the floor and if the flange isn't tight against the floor, the toilet could move. If it still rocks, I see no reason why you couldn't use toilet shims if the floor or the toilet bottom aren't flat. Note that any time you pull a toilet up you need to replace the foam gasket. Just don't use any type of caulk between toilet and floor.

Is this true???

This is a need to know question as I have just pulled up the toilet to do some plumbing repairs. The foam gasket looks fine and fluffy.

Is the toilet rocking on top of the floor surface, or is the floor itself flexing? Shims will only fix a poor fit to the floor surface, if the floor is weak, then it needs reinforced.

Use 8lb sheet lead.Used it many times in houses even on concrete.

A rockin’ convenience might be of assistance to some RVers IMO.
