Toilet Bowl Mold: What You Need to Know

Do you see mold every time you open the toilet lid? It's a common problem, because toilets are always damp, which is the perfect place for mold to grow. How can you get rid of it? And how harmful could it be? Here's what you need to know about toilet bowl mold.

Why Is Toilet Bowl Mold Harmful?

Mold doesn't just look bad. It can also cause health problems and spread to other surfaces in your bathroom. 


  • Mold can harm you and your family. It can trigger asthma attacks and cause allergic reactions. It can also cause coughs, wheezing, and irritation of your eyes, nose and throat.
  • Mold can spread. Mold spores are lightweight and can be thrown into the air by a toilet flush. Once they land on other damp surfaces in your bathroom, they can take hold in as little as 24 to 48 hours.

When Should I Hire a Professional?

Mold can be persistent. If you just have a little mold in the toilet bowl, you can clean it up with easy home remedies. Three household cleaners you can use to kill mold and clean your toilet bowl include:


  • Hydrogen peroxide
  • Vinegar
  • Bleach


If your mold problem is severe or reoccurs, call in professionals to help. Once mold has escaped the toilet bowl, or if your home remedies aren't getting rid of it, a professional can remove it for good before it spreads. Professional mold remediators contain mold so it doesn't spread during removal, thoroughly clean the mold, and help you fix the cause of the mold.
