Walking into your bathroom to see a mushroom sure is a disgusting sight! It is also very confusing.

Extensive moisture or possible mold infestation are the reasons for mushrooms growing in bathrooms.

It can and has happened to many others before you! It would be best if you were concerned because mold can grow in moisture-prone areas and allow the fungus to spread in your home.

Mushrooms Growing in Bathrooms: What Causes Them?

Mushrooms are fungi that grow in warm and humid areas, making your bathroom a very comfortable target.

You have extensive moisture or possible mold infestation when you encounter such growth. Mold is usually black or dark green and has a fuzzy texture.

They are usually the primary cause of mushroom growth because they thrive in damp environments.

So any leaky sink or incorrectly sealed bathtub or shower unit in your bathroom would quickly cause the spread of mold and, soon, tiny blooming mushrooms.

Can Mushroom Mold Be Dangerous?

Yes! Although not all mushroom mold is black mold, it is a massive problem if it is. Black mold (Stachybotrys Chartarnum) is very toxic.

It has a musty odor but could be mistaken for dirt because it spreads on the floors and walls, so you have to look closely.

The mushrooms themselves are not the problem, but the mold that breeds them. If you have children or pets at home, they could go sniffing or touching it, and it could hurt them.

They can start sneezing or dry coughing or wheezing …or all three! Sometimes even without contact because fungus releases pore into the air that can aggravate allergies and cause health problems.

Best Cleaners to Use for Mushroom Mould

Though it can seem like a stubborn substance, you can get rid of all types of bathroom fungi and prevent them from coming back for good with the right approach and cleaning materials!

Remember that some of these cleaning products can harm the skin, so wear protective rubber gloves and a mask and clean the mold in a well-ventilated area. The best cleaners to use are;

1. Baking Soda and Water

 Starting with an organic route, mix 1 teaspoon of baking soda and 2 cups of hot water into a spray bottle for your disinfecting. Spray on the areas and wipe.

2. Bleach and Warm Water

You can always produce your cleaners if you don’t want any store-bought products.

Combine 1 part of bleach and 3 parts of warm water and put it into a spray bottle. Spray on the infected area and let it sit before scrubbing it away. Dry once thoroughly.

3. RMR–86

This is a fungicide that can be bought in stores. This may be temporary in some situations, mind you.

However, it takes away the nasty color on the walls and can help prevent mold growth from coming back. 

How to Remove Mushrooms in Your Bathroom

Method One

 This is a temporary method, but it helps get rid of the mushrooms and start the cleaning process.

  • As we’ve previously advised, using gloves, pluck them out of the walls or floors or doors, they reside in. Remember, do not make direct contact with it.
  • Take a fungicide or homemade cleaner as suggested above and spray on the areas thoroughly. Then, let it rest for thirty minutes. 
  • Once the thirty minutes are over, use a brush to scrub the areas properly until they’re clean. Then, disinfect all the parts of the bathrooms because, as I’ve said before, their spores float around. They can find another base to continue growth.

Method 2

This method is required if you have a mushroom mold. Then, your problem is bigger.

The mushroom is formed from a very damp and adaptive environment, and you need to nip it at the bud by fixing the environment.

  • Remove all items that contain mold. Shower curtains, rotten doors, moldy furnishing, all of it, toss it away! Whether you pluck out the mushroom and clean the surface, these parts will revive the mold.
  • Then, if you leak somewhere, you should call a professional to check it out before it escalates. If your apartment is rented, call the rental office to check it out.
