Why Is There Moisture at the Base of My Toilet? - Executive Plumbing
Answer from Blake - Executive Plumbing in Lincoln, CA
Moisture or puddling around the base of a toilet usually indicates a problem with the wax ring or toilet flange. The wax ring is the seal between your toilet and the waste pipe beneath it. If the wax ring is damaged, too old, or wasn’t seated correctly, small amounts of water will escape every time you flush. Another possibility is that the toilet flange (the fitting that connects the toilet to the floor) is installed at the wrong height, or the toilet itself is slightly unstable and rocking, which can compromise the seal. To fix the issue, the toilet needs to be pulled up so the wax ring and flange can be inspected and replaced or reset as needed. Ignoring this problem can lead to water damage to your subfloor and unpleasant odors.
Summary:
Moisture at the toilet base usually means a failed wax ring or a flange issue. The only fix is to pull the toilet and inspect the seal underneath. Repairing it quickly prevents leaks from damaging your floors and keeps your bathroom sanitary.
