A toilet that rocks when you sit down almost always has a worn-out wax ring. It's not a reason to buy a new toilet. The fix costs $15-$30. A lot of service calls cost $100 to $150 just for the guy to show up.
Someone once replaced an entire toilet because it wobbled. The real problem was a ten-dollar wax ring that had gone flat after fifteen years. The toilet they threw out was fine. People overpay for this one, and it's a Saturday-morning project.
The full step-by-step is in the Fire the Guy playbook. Grab the free list below to get started.
Tightening one bolt all the way before starting the other can crack the porcelain base. Go a little at a time on each side, alternating.
Turn off the water valve behind the toilet first. No permit needed for this. The main physical risk is your back. Lift with your legs, and get help if the toilet feels too heavy to manage alone.
If the flange on the floor is cracked, sitting below the floor level, or rusted through, that's beyond a wax ring swap. That's a flange repair, and it's worth having a plumber look at it.
