Common Causes of Mould in Bathrooms

Poor Ventilation

When there is little to no airflow in a bathroom, moisture can easily become trapped. This moist environment is the perfect breeding ground for mould spores, which can quickly lead to the growth of ventilation mould.

Consistent Moisture

Often linked with poor venitlation, other features such as wet towels, bathroom surfaces, shower screens and more that are left without being properly dried or ventilated can make for a perfect space where mould feeds and grows.


Another common cause of mould in bathrooms is the presence of leaks. Even small leaks from taps or showers can create an environment that is conducive to mould growth. If you notice any leaks in your bathroom, be sure to fix them as soon as possible to help prevent mould from forming.

Problems Caused by Bathroom Mould

Allergies and Asthma

Mould can cause a number of respiratory problems, especially for people who suffer from allergies or asthma. Inhaling mould spores can trigger asthma attacks and cause a variety of other respiratory problems.

Structural Damage

In addition to causing health problems, mould can also damage your property. It can cause stains and discolouration on walls, ceilings, and floors. In severe cases, mould growth can even lead to structural damage.

Methods for Cleaning Bathroom Mould

Allergies and Asthma

There are a number of products on the market specifically designed for mould removal. Be sure to follow the instructions carefully when using these products, as some can be harmful if used incorrectly.

It can be good practice to test a removal product to see if it can get rid of mould in a small area before spending a lot of time applying it to bigger areas.

Use Mould Removing Home Remedies

There are some common household items that can help remove mould. One such item is bleach, which can clean mould off surfaces. However, it is important to use caution when doing this, as bleach can be corrosive and damage some surfaces. 

Vinegar is another effective mould removal solution. Like bleach, it is important to use vinegar with caution, as it can also damage some surfaces.

How to Prevent Mould from Forming

Keep Your Bathroom Clean and Dry

Mould thrives in wet and humid environments, so it is important to keep your bathroom clean and dry. Wipe up any water spills immediately and perform cleaning regularly. This includes taking a scrubbing brush to your shower floor and bathroom ceiling where necessary.

Use Mould Resistant Products in Your Bathroom

When painting or caulking around your bathroom, be sure to use products such as mould-resistant paint. These products will help prevent mould from growing in bathroom surfaces where they are applied.

Make Use of Bathroom Windows and Exhaust Fans After Showers

As previously mentioned, having poor ventilation can create an environment capable of rapid mould growth. The best way to counter this is by keeping airflow high with proper bathroom exhaust fan usage and opening bathroom windows, letting steam and hot air escape and reducing moisture on bathroom walls.
