You’d think that, after having had the caulking professionally removed, I wouldn’t need to worry about it again. But I did! You see, after a little over a year, the mold came back and I found myself in the same predicament. No matter how much bleach I used, it only temporarily cleared it up!
But, the caulking is not the only place that black mold grows in a shower. It also grows on the shower ceiling, around the shower drain, and even on a shower curtain. Mold growth is aided by areas with high humidity such as the grout.
I wanted to explore with you today these other areas that grow black mold in a shower! I know it seems fun and harmless, but I’m sure you’re aware of the potential health risks. Let’s talk about how to remove that black mold in your shower for good!

First, let’s talk a little bit more about why black mold grows in showers and why black mold in showers is dangerous and the health risks associated with black mold in the shower.
What Causes Black Mold in Shower?
Mold loves to grow in humid places, and the damp conditions in the shower may just be the most perfect environment it’s ever found. The bathroom surfaces provide absolutely optimal breeding ground for various types of mold that love to thrive on warm surfaces.
If there’s mold in your home, you need to eliminate both the mold and the cause of it – a water problem. That’s why it’s important to control the humidity in your home. You should always use a bathroom ventilation fan and leave the door to the bathroom open if you can. Leave the window open if there is a screen on it or if you can close the bottom part of the window (opposite of how most windows are opened).
Black Mold in Shower Health Risks
Luckily, today’s bathrooms and showers are constructed in such a way as to minimize the risk of getting Stachybotrys chartarum—the toxic black mold or “deadly mold” known as black mold.
This bacteria feeds on cellulose, which isn’t found in shower surfaces or zones. That’s why these areas don’t allow for the really bad types of mold to grow.
Stachybotrys is less likely to grow in tile, ceramics, and cement-fiber backer board.
But, it doesn’t mean the black mold that you see in your shower is safe for you either!
Some people prefer to request laboratory testing for mold, but it really isn’t necessary and can be pretty expensive.
What are health issues associated with exposure to mold?
Many people experience no physical symptoms from being exposed to black mold in showers, but those who have asthma, weakened immune systems, or sensitivities or allergies to mold can experience some physical symptoms from the exposure. These include things like:
- itchy eyes
- scratchy throat
- trouble breathing/respitory issues
- skin irritation
- yeast infection
- athlete’s foot
Even if you don’t show symptoms now, repeated and prolonged exposure can lead to a mold sensitivity over time and affect your health. Bathroom mold isn’t something to ignore at all.
How to Get Rid of Black Mold in Shower Caulking
While it is effective at removing the mold’s color and stains, many people found that it only prevents the growth of more black mold in the future, and did not actually remove the mold. Unfortunately this was what happened to me— 6-9 months after bleaching my walls, new black mold started to grow.
But bleach is really good for removing mold stains – which is good, because it does kill the mold. If you want to get rid of the possibility of future mold growth, you need to add an oxidizer to the bleach.
To remove mold stains from your clothes, try using white vinegar, baking soda, ammonia, oxygen bleach, borax or hydrogen peroxide.
One of the best things you can do to remove black mold in caulking is to just remove the caulking altogether. And no, that’s not difficult or time-intensive either. Just use new high-quality caulking and let it dry properly before using your shower again. This is important because after removing the moldy caulking, a good caulk will also help prevent water damage and future outbreaks of black mold on your tile and shower walls!
Adding new caulk is a great way to spruce up that moldy shower.
But, if your grout still looks like it’s in good shape, then try one of the following methods:
- Bleach (unless grout is colored or the tile is too brittle). Rub bleach into the grout using a stiff bristle brush and let it sit for 30 minutes and then wash with warm water, repeating the process as needed.
- Distilled white vinegar. Spray it on and let it rest for 30 minutes, and then scrub the vinegar through the grout, spray it again and let it sit for 30 minutes. Rinse the grout using warm water. Repeat the process as needed.
- Baking Paste. Use the method I followed to wash grout using baking soda, but allow it to sit for 10 minutes prior to rinsing and repeating as needed.
- Baking soda as well as hydrogen peroxide blend. Use the above baking soda paste, and apply it and then spray or sprinkle hydrogen peroxide on it, and rub the fluid paste. Rinse the area with water, and repeat as needed.
When you’ve removed black from grout in your shower, make sure to use a squeegee take out any water and moisture from your grout and tiles after showering to keep it from resurfacing.
