Dangers of mold in the bathroom

People with weak immune systems are advised to stay away from bathrooms with mold as it could lead to serious health complications. Besides the possible structural damage (in extreme cases) mold can cause to your building, here are ailments that can result from excessive exposure to mold:

  • Breathing issues – people with breathing complications such as asthma can find it hard to breathe inside a mold-ridden bathroom 
  • Skin irritations
  • Stuffy noses
  • Pulmonary hemorrhage
  • Allergic reactions

Molds come in different colors and shapes. Here are the common ones:


According to, most people breathe in the Aspergillus spores without getting sick. However, people with a weak immune system can suffer from Aspergillosis, an infection that results in several breathing complications including allergic reactions and lung infections. The symptoms include wheezing, coughing, and fever. 


The Chaetomium fungus loves dark walls. It thrives in wet soils, plant matter, and poorly ventilated walls. Chaetomium spores can cause serious health issues including severe breathing issues in people with a weak immune system and fatal allergic reactions. 


Acremonium causes numerous skin irritations and inflammations. This mold will appear in shades of pink, grey, white, or orange. 

Why mold loves the Bathroom

Mold thrives in the bathroom because the combination of moisture and heat creates the perfect environment for these spores to grow. They love the humidity inside the bathroom.

How to prevent mold from growing in your bathroom

You can prevent mold from accumulating in your bathroom or other damp areas of your house in several ways:

  • Keep the bathroom dry
  • After taking a shower wipe all the bathroom surfaces with a dry piece of clothing to get rid of the moisture. 
  • Open the windows to allow clean and fresh air to circulate inside the bathroom
  • Place an exhaust fan inside the bathroom to get rid of excess moisture
  • When cleaning pay special attention to hard-to-reach areas, crevices, and corners where mold spores can grow easily. 
  • Apply mold-resistant paint
  • Repair any leaking faucets or water sources inside the bathroom. The goal is to keep the bathroom as dry as possible when not in use. This includes ensuring that the water accumulating at the bottom during a shower drains well.

Mold-resistant paint prevents mold and mildew from building up on your walls. This is normal paint but with certain additives designed to break down mold spores and render them ineffective. Such paints contain mildewcide – a compound that prevents these spores from growing. Using such paint will help reduce the effect these mold spores will have on your bathroom walls. However, using mold-resistant paint is only a temporary solution if the bathroom is always humid.

Mold removal options

There are many options you can use to remove mold from your bathroom. Luckily, many of these options are organic and the products are easily available. Before we go into the step-by-step of removing mold from your bathroom, here are mold removal options you could try at home:


White vinegar is excellent in handling mold spores. Add undiluted white vinegar into a spray bottle and spray on the surface where the mold occurs. Let everything soak in for about 15 minutes before lightly scrubbing the mold off. Be careful while doing this as the goal is to get rid of the mold, not the paint. Allow everything to dry off.

Lemon juice

Squeeze lemon juice into a spray bottle and onto the affected area. Lemons are natural cleaners with a wide range of applications around the house. Once you have sprayed let everything soak for several minutes before scrubbing and wiping the surface with clothing.

Hydrogen peroxide

Hydrogen peroxide is also an important cleaning agent around the house. Put diluted hydrogen peroxide inside a spray bottle and work your magic over the affected surface. Let everything soak for 15 minutes before scrubbing the mold off lightly.

Baking soda

Baking soda and vinegar have a million uses in the bathroom and kitchen. Put 1-2 teaspoonful of baking soda inside a bottle with warm water. Mix well. Spray the mixture onto the affected surface. Let everything soak for several minutes before scrubbing off lightly.

How to remove mold from ceilings using hydrogen peroxide – step by step

  1. Always start with protective gear
  2. Since you will be spraying the ceilings ensure your eyes are well protected. The solution can be irritating if it gets into your eyes
  3. Have the right mix according to the manufacturer’s instructions
  4. Mix hydrogen peroxide solution with water parts as directed by the manufacturer. The standard ratio is 1:3 hydrogen peroxide to water parts
  5. Put this solution into a clean spray bottle and shake well to ensure everything mixes as needed
  6. Spray in the affected areas
  7.  Leave everything to soak for some time (about 15-20 minutes)
  8. Scrub the mold off lightly using a piece of clothing or a soft brush. Take care not to damage the paint underneath.

How to prevent mold from re-occurring

Once you have gotten rid of mold from your bathroom, here’s how to prevent it from re-occurring;


Add proper ventilation inside the bathroom. Bathrooms with poor ventilation do not dry out well. Add windows to bring in natural light and help to prevent humidity build-up.

Add exhaust fans

Exhaust fans can work well where it is impossible to enhance the ventilation. They will get rid of the moisture and keep the bathroom dry.

Paint your walls with mold-resistant paint

If you can’t get rid of humidity in the bathroom paint the walls using mold-resistant paint to discourage the growth of mold spores.

Use ceiling cladding

Ceiling cladding panels are waterproof. This means that they prevent the surface from becoming mold and effectively control mold formation. Ceiling cladding may be expensive at first but it is maintenance-free after installation and rarely tampers with your decor.
