Something as simple as a cracked floor tile or a slightly uneven floor can cause a rocking toilet. This is often easily fixed by an adjustment to one of the legs of the toilet. However, any unevenness in the flooring can cause a rocking toilet.
The ring can corrode or break, loosening its grip on the bolts. If the rocking comes back after a while, or if the bolts loosen up and won't retighten, a damaged flange is likely the cause. The solution is to remove the toilet and either replace the old flange or repair it with a flange repair kit.
Flange / Wax Ring
If this develops issues you can have a loose toilet and a new wax ring may be in order. You do not want to reuse an old flange or plastic rings as this can lead to leakage. Another way to eliminate a rocking toilet is to place flexible Wobble Wedges plastic shims underneath the base of the toilet.
If your toilet isn't solidly fastened to the floor, there may be trouble in your future. Any movement of the toilet damages the wax seal. That leads to leaks and major repairs. To steady a rocking toilet, cut plastic shims to fit and slip them underneath (you may have to remove caulk before adding shims).
A loose toilet is a pretty quick and easy problem to solve, but we recommend hiring a professional because an inexperienced DIY-er may make it worse or cause other problems. Expect to pay $50 to $150 to fix a loose toilet.
The flange is damaged
Sometimes, it's not the flange bolts that are causing the rocking issue but the flange itself. When the flange is damaged, a rocking toilet is typically accompanied by other unfortunate symptoms, like leaking at the base of the toilet, and the presence of unpleasant, foul smells.
🚽 Caulking Prevents Water Contamination
It could be water splashing out of a bathtub, mop water, water from a shower and even misguided potty training from your young boys who seem to miss the toilet bowl every single time! Without caulk around the toilet base, water can get under there and sit for a long time.
The wax ring is exactly what it sounds like: a ring made of sticky wax that helps form a watertight seal between the bottom of the toilet and the sewer pipe. It requires no maintenance and can last 30 or more years, often as long as the toilet itself. But sometimes wax rings can dry out, crumble, and fail prematurely.
On average, most toilets will have a lifespan of between 10 and 15 years, even with regular use. The lifespan may vary depending on the toilet model and the wear and tear it experiences over the years. Most toilets will start to give you warning signs indicating the time for replacement is near.
Once a week at least.
Tetro says your bathroom is the ultimate bacteria host; E. coli can be found within six feet of the toilet and in the sink. To keep it at bay, disinfect the toilet and sink at least once weekly, and the bathtub every two weeks — more if you shower often.
Over time stress fractures and hairline cracks may develop that are not visible on the surface. Although it may seem otherwise, household toilets are used and abused far more often than any public restroom facility. A cracked toilet can cause major water damage in a home and it can occur suddenly and without warning.
There are purists out there that may say it must be level, but if it looks good setting there, I would let it set on the floor with no shims. It should not affect the operation of the flapper or valve that flushes the toilet.
The toilet's flush valve will typically last 6-7 years. A toilet fill valve might only last four to five years. In general, you should expect to replace the parts in your toilet every so often while keeping the actual bowl in place.
As a result, having a local plumber replace your toilet's wax ring can be anywhere from $75-250 depending on the cost of the trip charge and whether anything else is discovered in the process that needs fixing.
While a professional plumber can change as much as $200 for a service call to reset a toilet, a DIYer can do it for just $10 to $20, the cost of a new wax ring. It does require careful work, however, to ensure that you don't crack or otherwise damage the toilet as you move it.
Another common sign is a bad odour in your bathroom. A damaged wax ring not only creates a leak every time you flush your toilet, but it can allow gases from the sewer system to leak into your home. This isn't just a sign of a damaged wax ring but also a sign of a serious health risk.
Bad Odors Coming from the Toilet
It's likely that what you're smelling is sewer gas that's made it past the wax ring. Don't mess around with this type of situation. Sewer gases are harmful. Not only do they make people sick, but if there is an open flame, the gases could cause an explosion.
If the wax ring isn't sealed correctly, it can cause wastewater to leak from the bottom. Leaking water can lead to mold around the floor. A poorly sealed wax ring can also cause foul odors to stink up your bathroom. If you smell sewage or see water leaking, then you may need a new wax ring.
