Black Spots on Bathroom Ceiling – Mold on Bathroom Ceiling

You walk into your bathroom and notice black spots on the ceiling.

Is it mold? If so, How should you get rid of it?

In this guide you will learn not only how to Identify these black spots or stains on your bathroom , but also how to Remove them effectively & Prevent them from returning.

Black Spots On Bathroom Ceiling – What Are They?

There can be two types of black spots found on bathroom ceilings. One is mold and this is the more dangerous kind.

Should you notice this, get it removed and treated right away. Pay special attention to the area above the shower because this is one of the more likely places you’ll find it.

Wet air rises from repeated use of the shower, going straight up to the ceiling. Condensation can quickly develop resulting in black mold.

While mold is likely to form on bathroom ceilings due to moisture levels and humidity, there’s another type of black spot that can develop. This is called ghosting.

Ghosting is caused from the following ways:

  • Dust particles
  • Soot
  • Burning candles
  • Smoke
  • Lack of insulation

Usually, black spots from ghosting form in a distinct pattern such as straight lines, matching the joists or house frame.

This is one way to tell the difference between mold and ghosting.

If you are uncertain whether you have mold or not, call a professional.

How To Tell If It’s Actually Mold

So, how can you be sure if you have black mold on your bathroom ceiling? One way to tell is in the pattern or how it appears.

For other signs you have mold, look for:

  • Dark circular spots
  • More prominent around the perimeter
  • Musty smell
  • Dark black, green or orange colors
  • Water stains
  • Discoloration on ceiling

What Causes Mold On Bathroom Ceiling?

There can be several causes of mold appearing on bathroom ceilings.

Because of how wet the air in bathrooms can get, it is the ideal place for mold to grow.


This is the most common cause of mold. The substance thrives in humid, wet environments. 

Water from the shower rises with no place to go and it winds up on the ceiling.

Over time this builds up and causes mold — that’s when you can see those visible black spots on your bathroom ceiling

Bathrooms are one of the dampest places in the house and therefore, it’s easy for mold to grow there. 

Lack Of Ventilation

Many bathrooms don’t have windows and in ones that do, they are small. A lot of times people keep these windows closed.

With no place to escape, the moisture and wet air rises, gets trapped and forms into mold.

While many bathrooms have vents or fans, it’s important to make sure these are working properly.

Any dust or blockage can prevent wet air from escaping.

Keep your bathroom fan clean and if it is broken, fix it or replace it right away.

Bad Insulation

If your bathroom is not insulated well, this can be another cause of black mold spots on your bathroom ceiling.

Outside air sneaks in and mixes with the inside wet air creating an environment suitable for mold.

Look for cracks, gaps, thin walls or any place air could be getting through.

It may be worth adding insulation or fixing these holes to prevent moisture and wet air from coming in.

No one wants mold and any steps you can take to prevent it will help in the long run.


Water can often lead to mold growth. If you have a leak, this greatly increases the chances of mold. 

Check your bathroom carefully and repair any leaks or dripping pipes immediately.

Signs you have a leak include water spots, hearing water run/drip when faucets aren’t in use and excess water on the walls or ceiling.

All it takes is a little extra water, wetness or moisture for mold to develop. The last place you want a leak is in the bathroom where water is constantly being used.
