How to Remove & Prevent Bathroom Mould


Have you noticed spots of mould growing on your shower tiles and wet areas? Get rid of mould in your bathroom safely by following our easy step-by-step guide and avoid issues in the future!

Imagine taking a nice warm shower with scented candles lit and a song playing in the background.

Sounds dreamy, doesn’t it? You’re also creating a warm, damp breeding ground for mould to thrive. But don’t worry; you don’t have to give up on your hot showers. All you have to do is take some preventative steps that will eliminate the probability of mould growth. And if you already have a mould infestation, we will show you how it can be cleared up.

Bathroom Mould

Removing mould from your bathroom doesn’t have to be difficult. But before we look at the best ways to clean mould from your bathroom, let’s look at some common causes of mould.

Causes Of Mould In Bathroom

Mould spores and growth are commonly promoted in dark, damp areas, which is exactly what a bathroom is. You may use hot water to shower and relax while creating the perfect environment for this uninvited visitor.

There are several reasons for mould growth, the primary one being humidity from warm showers. Apart from that, a lack of ventilation can contribute to mould formation. This is because the moisture levels and humidity in the bathroom have nowhere to go, leaving the bathroom walls slightly damp and creating moisture that mould feeds on.

Another reason for excessive mould growth is leaky toilets, taps and drain pipes. These leaks are often hidden, giving them more than enough time to seep into the flooring and bathroom walls. Even damp cellulose materials like plasterboard, fabric, and grout are breeding grounds for mould due to their moisture.

Preventing Mould In the Bathroom

Though mould growth is a common problem, there are several ways to avoid it. Note that these tips are not meant to remove bathroom mould but can be used as a preventative measure.

1. Leave The Windows Open

The main culprit for mould growth is the moisture that remains after you shower. To avoid this, leave the windows in your bathroom open after the shower. This will allow all the remaining moisture to escape instead of lingering in the bathroom.

When the bathroom is properly ventilated, it can reduce the chances of condensation seeping into the bathroom walls, windows or bathroom ceiling. This further eliminates the probability of mould growth.

If you do not have windows installed in your bathroom, try using a dehumidifier or a ventilator fan. Both these devices are designed to eliminate any excess moisture, so you do not have to depend on windows for ventilation. If you have a bathroom exhaust fan, switching it on after a shower will help keep your bathroom ventilated.

2. Clean The Shower

Maintenance is critical in mould prevention. To eliminate the probability of mould growth, clean the shower, including shower trays and panels, with a dry cloth. This process, along with proper ventilation, will remove all excess moisture in the room.

3. Add Plants That Purify Air

Certain houseplants have to purify properties that allow them to absorb any moisture in the air. This method can prevent mould growth and dismantle the existing mould.

The English Ivy is a popular purifying plant, typically used in smaller bathrooms. You can hang it in a plant pot and place it on one of the bathroom cabinets, whichever you prefer.

Apart from the English Ivy, plants like Peace Lily, Boston Fern, etc., do an exceptional job of retaining moisture. Peace Lilies are plants that depend on a lot of sunlight, which makes them ideal for bathrooms with windows. If you do not have windows, plants like the Boston Fern and Reed palms will be best as they do not require much sunlight.

4. Clean The Bathroom Regularly

A place you use daily should be cleaned regularly to avoid breeding mould, limescale, and bacteria. Cleaning and drying the bathroom, including hard-to-reach areas such as the grout, will be beneficial in the long run.

Apart from cleaning the surface of the bathroom, be sure to clean your towels and bath mats to prevent mould and the accumulation of bacteria. And if you notice any foul odours coming from the drains, be sure to clean them correctly. There are various DIY methods to do this, or you can call your local plumber.

5. Use Mould-Preventing Paint

Since mould build-up is a common issue, many paint manufacturers have used mould-prevention additives. Deciding on mould-resistant painted walls can be an extra step to prevent mould, and you can take showers without worrying about retaining moisture.

Mould-resistant paint comes in various colours, especially ones made for bathrooms. This way, you won’t have to compromise on your aesthetic, and you can keep your bathroom protected and kill mould.

Assessing The Bathroom Mould

Getting rid of bathroom mould spores is quite a task, especially if you want to refrain from using harmful chemical products. To remove mould, you must first figure out the type of mould you’re dealing with and how severe the problem is. This will enable you to choose the right solution for removing mould.

The most common type of mould found in bathrooms is black mould, which is also the toughest to remove. Black mould forms in clusters or groups in various spots in the bathroom and can emanate a musty, unpleasant smell.

Though it is the most unappealing one visually, black mould is not as much of a threat to your health as other types of mould. Black mould majorly causes a problem if you have either allergic reactions, skin irritation or asthma. Irrespective of your health condition, you must always wear protective gear, rubber gloves and snug-fitting face masks while removing black mould.

How To Remove Mould In Bathroom

If it’s too late for preventative measures, and mould has already been set in your bathroom, here are steps to remove mould in the bathroom.

1. Use White Vinegar

White vinegar is an allrounder for home cleaning. When you spot black mould forming, immediately pour undiluted white vinegar onto the affected area. You can also pour it into a spray bottle and generously spray it on the mould. You can also use hot water or warm water to wash away the vinegar and remove any remaining porous materials.

Since this is a natural remedy, it might not be enough to tackle more severe mould issues. You may depend on bleach or chemical cleaning solution to clean mould in those cases.

2. Use Bleach

If you want to remove bathroom mould that is adamant from silicone sealant or grout, use bleach and scrub with an old toothbrush, dedicated scrubbing brush or cloth. This will allow you to reach farther areas and remove mould from all hard-to-reach, smooth surfaces.

However, ensure that you take safety precautions from the bleach fumes by wearing protective gear and allowing more ventilation.

3. Mould Removing Solution

If you’ve tried white vinegar and bleach, yet the mould remains on the surfaces, you can try a mould-removing solution. These mould removal cleaning solutions contain harsh chemicals that can strip away all the mould from your bathroom.

However, since they contain more than one toxic substance, be sure to protect yourself and wear protective gloves and face masks. Also, keep a window open so that toxic fumes can escape. Gloves are mandatory as coming into contact with these cleaning products as harsh chemicals can result in your skin burning.

Additional steps that you must follow while using a mould removal solution are:

  • Test the solution in a small area initially
  • Follow the instructions on the bottle
  • Set the timer according to the time mentioned in the instructions
  • Wash it off with a sponge or damp cleaning cloth
  • Keep repeating until the mould is completely gone
