Warning: This is Why You Have Mold in Your Bathroom

Do any of the bathrooms in your home contain a terribly ugly blue, green, or black crust around plumbing fixtures and walls?

This is mold and mildew.

If you have mold in your bathroom, it’s because something went wrong and that something needs to be corrected. Because if there’s one thing you don’t want in your bathroom — it’s mold.

What Causes Bathroom Mold?

Lack of Ventilation

During hot showers and running the sink with the hot water faucet turned on, steam can buildup within the bathroom. This steam needs a place to go, otherwise, it will build up onto the walls and surrounding surfaces. Over time, this condensed moisture will promote the growth of mold and mildew.

This is why every bathroom should be equipped with an exhaust fan that can remove the moisture from this room (it should be turned on every time hot water is used).


Between the sink, toilet, shower, tub, and all of the plumbing pipes running to and from these fixtures, it’s possible for a leak to occur from time to time.

These leaks can burst onto the scene and cause maximal damage in an instant, or they can be slow-dripping leaks that go unnoticed until mold slowly starts to appear. Mold can even exist underneath fixtures and behind walls, staying hidden for months — even years!

Damp Supporting Cast

Inside each of your bathrooms there’s going to be rugs, towels, wallpaper, grout, drywall, etc. All of these materials can trap in moisture, which can cause mold to grow if they’re left unattended.

Make sure all rugs, rags, and towels are washed every couple of days. You should also ensure that the envelope of your bathroom is properly sealed — there are no holes that expose drywall, grout is always maintained, and that wallpaper is never peeling.

It’s easy for mold to start growing (especially in the bathroom), which makes it all the more dangerous. If you’re sick of mold, focus on repairing leaks and removing moisture. Whether it’s adding an exhaust fan or repairing a leak — you can count on us!
