When a toilet lifts off the floor, it can be annoying while in use but otherwise forgotten about. However, a rocking toilet can cause serious aesthetic and structural damage if left too long to wobble. A toilet that shims could lead to a slow leak in sewage gas, a wet floor that can cause damage to subfloors from a water leak or a cracked fixture that needs to be replaced entirely. Addressing a shaky throne at the first sign of a shift can save you from having to fix the floor or the fixture, and you will definitely be more at ease each time you rest upon the porcelain perch.
Seat Situations Solved
It may not be the toilet that is making you woozy when you take a seat upon the throne. A loose toilet seat could be the culprit. A shifting toilet seat is a fairly easy fix. At the back of the seat toward the tank are the screws that hold the seat to the toilet. If the screws have a cover, it is easy to pry from its mooring with your fingers or a flathead screwdriver. Tighten the screws to the toilet without overtightening, which can crack the seat or the toilet. If the screws are stripped, you may attempt to replace them or buy a new seat, which is a reasonably inexpensive fix.
What Causes a Toilet to Wobble
If the floor of the bathroom was remodeled recently, this can cause a toilet to be unsettled in its housing. The new flooring may be pressing on the wax ring incorrectly so that it can't get a good seal. The flange can become corroded due to tank leaks that went on too long, a dripping inlet valve connection or condensation that gathers on the tank and compromises the flange eventually. If shims are used to match the toilet to the height of the floor, it will cause an eventual wobble in the fixture and need addressing sooner than later.
Fix A Rocking Toilet
To fix a rocking toilet, check the flange and the mounting bolts first. The metal or plastic ring sits below the toilet and connects it to the floor with mounting bolts. It attaches to the drain pipe and should fit snugly under the base of the toilet so that it is secure and doesn't have wiggle room. You may be able to simply tighten the bolts from each side of the flat edges that extend from the base to fix the wobble. If not, you'll need to remove the toilet and check out the flange. If it is bent, eroded or otherwise compromised, replace the flange and the wax ring, if needed, and return the fixture to its spot.
