I have a toilet that rocks (wobbles) when I sit on it. According to one plumber it's because the floor is uneven.
1) One plumber recommended I use grout to set the toilet onto the floor so it will no longer rock.
2) Another plumber recommended I use plastic shims and caulk around the base of the toilet so it will no longer rock.
What do other people think? Does it make sense to grout or should I go with caulk? Which method is better? If I go with grout, how would I ever get the toilet off the floor (eventually I assume all toilets need to be replaced)?
