Mushroom growing in the bathroom

Is mushroom growing in bathroom enough reason to worry? Many people find it absurd to see a mushroom grow in such a strange place. Of course, it’s weird because no plant can survive in such a strange environment.

In this article, I will provide answers to why mushrooms grow in the bathroom, the risks and way forward. Please read.

Reason Mushrooms Grow In A Bathroom

I have a unique way of solving problems. It involves knowing the root cause of the problem. That way, you can nip it in the bud and prevent a reoccurrence of that problem, which is what we will be doing with regards to this subject.

But first, is there any risk finding mushrooms grow out of your bathroom?

Trust me, there is a risk, and it’s more severe than you think. There is a reason for you to act before things get out of hand. You might claim most mushrooms are harmless, so what’s there to worry about when one grows in the bathroom?

But there is a ton of reasons you should worry. Having mushrooms grow in your bathroom is a clear indication of the possible moisture issue. And if not tackled earlier, it may lead to severe mold infestations. 

So, is there cause for alarm? Yes, there is. 

Here is also why mushroom is growing indoors, in your bathroom even when you didn’t plant one there.

First, know that fungal spores form the mushrooms growing in your bathroom. And these spores are microscopic. In other words, they are small and light. Our naked eyes cannot see them because of their sizes.

Reason Mushrooms Grow In A Bathroom

However, being light makes it super easy to transport these spores. They are easily carried by small wind to any location. Plus they are also present in our window screens, clothing and even on plants.

So now you know how mushrooms find their way into your bathroom. It was either unknowingly carried by you or via the wind to your home.

But there’s one point you should know. Mushroom does not just grow. Two single-celled spores have to come together before it can start growing.

Now here is another thing. And it’s also the reason mushrooms have the power to invade your bathroom.

Low light, high heat and high humidity are conditions mushrooms require to thrive. Your living room can’t guarantee this condition, and that’s why mushrooms don’t grow there. 

Now, what about the bathroom? Hmmm, perfect for mushrooms to thrive. The bathroom has an adequate condition such as excess moisture, high heat and low light condition, which are things mushrooms need to grow on bathroom floors, walls and ceilings.

Just take a quick look at areas where moisture gathers. You might find something growing there.

The Risk Factor Of Having Mushrooms Grow In Your Bathroom

Before we go deeper into discussing the risk of having mushrooms grow in your bathroom, let’s consider a common safety concern.

You might be eating mushrooms and feel the one growing in your bathroom would be safe too. Well, I hate to be a carrier of bad news. But please, for the sake of your health, never consume any mushroom that grows in your bathroom.

The Risk Factor Of Having Mushrooms Grow In Your Bathroom

Also, even if you have a poisonous mushroom growing in your bathroom, know that’s not the main underlying issue. In other words, the mushroom is not the threat. It’s just there because the environment is conducive and it happens to be transported there by you or the wind.

In short, many mushrooms don’t cause harm. I mean a plethora of them out there, but those that grow indoor and outdoor.

Now, what’s the real danger when mushroom starts growing in your bathroom?

Well, we talked about this before but let me repeat it. The real danger is that your bathroom has a severe moisture problem. And if you don’t act, then don’t be surprised when the more severe and threatening problem occurs.

The thing is excess moisture that gave rise to the growth of mushrooms in your bathroom can also support the growth of mildew and black mold.

“Black mold also called Stachybotrys chartarum, is a type of microfungus known to produce its conidia in slime heads. This mold mushroom is devastating. It can cause sneezing, chronic coughing, chronic fatigue, eye irritation, persistent headache and mucous membranes of the throat and nose.”

So, you can see that mildew and mold can be dangerous. And for the records, both flourish under the same condition where the mushroom grows.

Mold mushrooms cause shortness of breath, including asthma-like symptoms. But these upper respiratory problems are not the only conditions that it causes.

One can also experience lower respiratory problem too. These include tightness of one’s chest, which can be very discomforting. Mold mushroom growing in the home might also cause an individual to develop asthma, even if he or she doesn’t have.

Another scary thing about black mold spores is death. When an individual is exposed to it for too long, the spores can shut down one’s organs, damage the brain or incapacitate the immune system. And all of these can result in sudden death.

How To Prevent Mushroom Growing In A Bathroom

We have spoken about the dangers of letting a mushroom grow in a bathroom. The problem is not the mushroom but what having it grow in such a place signifies.

But there are ways you can prevent this from happening. And that I am going to reveal to you. You also have to take proactive measures to ensure it doesn’t happen.

Now let’s take about the things you need to do when a mushroom is already growing in your bathroom.

Many people would consider using a fungicide. It’s a regular thing. The fungicide might help to tackle the problem, but it would only be a temporary fix.

How To Prevent Mushroom Growing In A Bathroom

Yea, I said this because it’s a waste of time and effort trying to fix a problem temporarily. Know that the issue isn’t mushrooms there. It’s the mold and mildew that are growing, which might be spreading faster than you think.

When you take a bath and spend a couple of minutes every day under this condition, you are already putting yourself at risk.

So, using a fungicide to treat mushrooms already growing in your bathroom isn’t enough. It won’t put an end to the fungal problem you might experience in the future.

Below are steps you need to take to prevent mushrooms from growing in your bathroom.

Consider humidity levels

The first thing to consider is the level of humidity your bathroom has. If it’s high, then nothing will ever prevent mushrooms from taking their spots in your bathroom.

Even toxic mold can develop under high humidity. High humidity can also destroy your bathroom’s underlying wooden structures too.

So what can you do in this kind of situation? Make sure there is proper ventilation, simple!

You can install a suitable ventilation fan in your bathroom. This fan helps remove humidity.

 Keep your towels dry

Your towel needs to dry as quickly as possible after use. It can serve as a breeding ground for mushroom or mold. So keep it in an area with proper ventilation. That way, it would dry faster and ensure you don’t give room for mold to develop.

You should also consider washing it properly often. Don’t wait for when it’s dirty before taking action. Always keep your towel clean.

 Fix leakages

Your bathroom should not remain wet always. When not in use for some time, bathrooms become dry. However, if yours isn’t this way, then there is a problem. It could be that the seals around your bathtub or toilet are leaking.

If this is the case, then have them fixed as quickly as possible. Don’t wait for mushrooms or mold to the buildup before you take action. Have them repaired by a plumber. And if there is are cracks on the flooring, then ensure they are fixed so that water won’t stay there for long.

How To Get Rid Of Mushrooms Growing Out Of A Wall And Other Areas In Your Bathroom

Now let’s discuss ways to get rid of mushrooms that are already growing in your bathroom. How can you tackle this condition?

Pick mushroom from the floor

The first step is to wear rubber gloves on both hands and pick the unsightly fungi from the floor, ceiling, or wall. Then after removing the fungi, mix the bleach in water and clean the area thoroughly.

What happens if the mushroom returns after a while?

Ensure the affected area is properly cleaned with a powerful household disinfectant, particularly one that contains benzalkonium chloride. This chemical will help to destroy any mushroom spore that is remaining. You can also apply a fungicide if you feel there is a need to apply it.

Remove mushrooms from tiled walls

Remove mushrooms from tiled walls

If your bathroom has a tiled wall, then you can use bleach chloride. But ensure there is no color grout to prevent it from fading. Now spray the cleaner into the affected area and allow it to remain there for at least 35-40 minutes. After that, you can scrub with a hard brush and rinse off with warm water.

However, if you don’t like the idea of using chemicals, you can go with a more natural product. Distilled vinegar can help tackle mold growth in your bathroom, and is the same process as when you are using a cleaner with bleach only that you have to apply the distilled vinegar and rinse off with warm water twice.

The reason most people prefer vinegar is not just because it is natural. It will also ensure you don’t experience grout discoloration or any form of deterioration.

A natural cleanser will also make sense when you are dealing with a mushroom that is growing on a painted wall.


I hope you now understand why making sure that mushroom growing in the bathroom does not happen. The thing is mushroom growing is not the problem. But the conditions in which a mushroom grows, particularly indoors, also favors the growth of mold and mildew. So make the right decision today to protect your health. Ensure you don’t have mushrooms growing anywhere on your bathroom. If you do, then refer to the tips on this post to fix them.
