Why is There a Ring of Mold at the Base of My Toilet?

We’ve all seen it at one point in our lives: the dreaded ring of mold around the base of the toilet. Where did it come from? When did it first appear? And what the hell caused it in the first place? If you’ve just discovered a ring of mold at the base of your toilet, then we’re here to help. And we’ve got some answers. Here are a few things you can do to determine the cause of mold at the base of your toilet – and to prevent it from happening again.

1.    Check the wax ring

More likely than not, if you see mold where your toilet meets the floor, it’s due to a bad wax ring and seal. If the wax ring is cracked or was improperly sealed, it allows mold, bacteria, and even sewage (yuck) to escape from beneath the toilet. To solve the problem, you (or preferably a professional plumber) will have to lift up the toilet, remove the old wax ring, and install a brand new assembly. This isn’t terribly expensive, but it’s important to get the job done properly to avoid a repeat experience.

2.    Clear the drain line

While you’ve got the toilet up, you might as well have the drain line checked and cleared. If the drain line is blocked in any way, the toilet won’t be able to flush right. This also leads to an increase in pressure on the wax ring, which will just cause it to crack or burst again. Have a plumber clear any drain clogs while the toilet is disassembled.

3.    Keep the area clean

Proper cleanup is important to keep mold and bacteria away from your toilet. Make sure to regularly clean and disinfect your bathroom area to avoid nasty mold and mildew growth at the base of your toilet, the toilet bowl, and the toilet seat. You and your guests will appreciate having a clean, sanitary bathroom experience.
