Beneath The Bathroom Sink
Mold growth can occur under a bathroom sink in 3 common scenarios. First, mold growth can appear after a leak from the water supply lines or the drain pipe. Typically a leak in the supply lines will cause mold growth and water damage to the bottom of the vanity/cabinet. A leak in the drain line is less common, but can occur in the cabinet or in the adjacent wall.
Second, mold can occur due to condensation. Typically this happens in a home with poorly or completely uninsulated exterior walls. These walls remain cool, while the interior of the home is heated. This temperature differential creates a surface below the dew point, and thus, condensation occurs. A moisture meter is helpful for differentiating condensation based mold growth from leaky plumbing. Except for extreme circumstances, the condensation based mold growth will not exhibit a measurable level of increased moisture in the wall. However, mold growth from a leaky pipe certainly will.
But looks can be deceiving. Damage from old leaks can leave stains that can appear actively wet. In the image below a moisture meter shows the moisture content of the cabinet is normal.
Notice the damage to the plywood beneath the countertop.
Hydrogen Peroxide And Baking Soda
- EC3 mold solution spray
First, you should apply a thick layer paste made of baking soda and a little water over the mold. Then, pour 3% hydrogen peroxide over it. You will see that it begins to fizz, which means that destroying the old and stubborn mold starts.
Accelerate the process by scraping the deposits with a scrub brush. Once you have removed all the mold, you should dry the area and add the EC3 mold solution spray over it.
See The Stain Then The Mold Is Still There
About three months later the mold reappeared and seemed to have spread across a larger area of the bathroom ceiling. I realized that the ceiling was not stained but rather the mold was not fully removed. Apparently the Clorox bleach did not remove the mold but merely scraped the surface spores off leaving the roots behind. The ceiling did not need a paint job but needed for the mold to be removed completely.
When I saw the cathedral ceiling decorated in mold I was thinking of doing a complete bathroom makeover. I was trying to justify it but still was not happy about the presence of mold in my bathroom. Every time the bathroom would steam up, the moisture would gather on the splotches of mold and drip back into the shower stall. This did not sit well with me and I decided to give it one more shot to get rid of the mold.

Remove Mold From Drywall/painted Walls
Mold can often grow on drywall and painted interior walls, especially in areas where moisture and humidity are a factor, such as kitchens and bathrooms. Walls can also be affected if your roof or exterior walls are infiltrated by water. If the drywall remains wet, mold can begin to grow and penetrate the drywall throughout. When this happens, the drywall must be removed and replaced, as you will not be able to get rid of all mold under these circumstances.

Mold Growth On The Wall Behind The Toilet
The same interactions that cause moisture and mold growth on toilets can also lead to mold growth on the adjacent wall. Typically this occurs when the cold surface temperature of the toilet cools the temperature of the wall directly behind the toilet. Once the wall temperature drops below the dew point, moisture condenses and mold growth ensues.
Not easy. If mold growth occurs on the wall, it is because the distance between the wall and the toilet is very small. Often the distance is less than 1, leaving little room to insert a scrub brush, rag or other cleaning utensil. A tooth brush can work well, but as one can imagine, the work is tedious. In cases with severe mold, the toilet must be removed to provide access.
Bathroom Mold Prevention And Remediation
After you learn how to remove mold, youll want to prevent mold in the future. The key to stopping most mold is to control dampness. The worst infestations usually occur in damp crawlspaces, in attics and walls where water has leaked in from the outside, and in basements with poor foundation drainage. Stopping leaks, ensuring good ventilation in attics, keeping crawlspaces dry and routing water away from the foundation are the best defenses on how to get rid of mold.
Almost every home gets mold, and that means theres a need for mold remediation. Well show you how to remove major mold infestations.
Mildewcide in paint is usually effective for controlling surface mold in damp rooms like bathrooms and outside in shady areas. Many paints already have mildewcide in them.

Best Paint For Bathroom Mold And Mildew
- Benjamin Moore Aura Bath and Spa Paint
- Benjamin Moore Regular Aura Interior Semi-gloss
- Sherwin Williams Duration Home Interior Satin, or Semi-gloss
- Zinsser Perma-White Paint
All of the recommended products above are effective at preventing mold and mildew growth. These paints are formulated for that specific purpose. You can certainly buy an anti-fungicidal additive and mix it with paint you already have, but improper mixing can cause problems with the paint.
I would definitely choose a semi-gloss paint, or at least satin, when painting your bathroom walls, especially the walls surrounding the shower. The shinier the paint, the more it’s going to resist water instead of absorbing it. Apply one coat of primer and two coats of paint.

Remove The Source Of The Mold
As mentioned before, mold or mildew on ceiling grows on a dark and humid area. If the black spots are present on the visible part of the ceiling, the root of the problem may start from behind it. You need to check the ceiling and create the inappropriate environment for the mold.
Give the area enough sunlight or bright heat to inactivate the mold. Once the colonies died, it would be easier to clean, and there should be less possibility for the mold to grow back.

What Happened & Where Did The Mold Come From
The primary reason as to why mold issues appear in ones bathroom is primarily due to poor ventilation of high levels of moisture. Keep in mind that bathrooms are the perfect setting for mold spores to grow. There is always plenty of water and unless you live in an upscale home there is typically not so much air space. This makes it very difficult for humidity levels to regulate after a normal shower let alone a ten plus minute shower. Thats why its very important for your bathroom to have proper venting both during and after bathing. Sometimes contractors will skimp on a window and install a bathroom fan that is supposed to exhaust outside the home. In my case, it does not exhaust outside the home but rather into the attic which is why its so difficult to keep the humidity down.
In most cases mold is found in places like under the sink, behind the refrigerator, dirty air conditioner vents, and other crowded space with high moisture levels. The key is to make sure that areas where there is greater chances for increased levels of moisture get vented properly. The ventilation allows for the moisture to escape and leaves the space dry even where high levels of moisture exist.

The main reason black mold infests your bathroom is due to the humidity and plentiful supply of water. Such condition provides the perfect ground for mold development.
Water coming out from basin, bathtub, and shower will create wet surfaces that are claimed by black mold as the place for it to live in.
In addition to water supply, another cause of black mold infestation in the bathroom is related to the steam evaporation. If you like using warm or hot water in the shower, the chance of black mold growing in your bathroom increases.
The bathroom does not have well ventilation system compared to other rooms in the house. It also becomes the cause that can increase humidity from the steam and water circulation inside the bathroom.
Removing Mold From Different Surfaces
Once the root cause of the mold has been dealt with, its time to address the visible mold itself. Often the infestation is worse than can be seen with the naked eye, so its important to do more than wipe mold off surfaces and hope for the best. The mold you see is the spores or fruiting body of the fungus, but often the hidden roots survive a first attempt at removal and the mold comes back. Heres how to remove mold for good, wherever you find it in your property.
Before you start: Make sure to ventilate the work area properly, and wear appropriate personal protective equipment to protect against mold spores that will be disturbed when you begin working. Gloves, safety glasses, and an N95 or better mask are all essential. Wear a long sleeved shirt and pants to avoid getting spores on your skin. Try to close off the area from other rooms to prevent spores from spreading throughout your home, and consider renting a HEPA air filter.
Pro Tip: The EPA recommends only removing mold yourself if it covers an area less than 10 square feet. Any larger than that and you need to call in the pros.
