The bathroom is often the most humid room in the house, potentially causing mould and mildew to appear. Mould not only looks unsightly, but can be dangerous to your health if left untreated for long periods. So how can you remove and prevent mould in the bathroom? Let’s find out.

Common causes of bathroom mould

Mould thrives in dark and warm conditions, so it’s no wonder that bathrooms are so susceptible to this unwelcome house guest. Here are the most common causes for mould in your bathroom: 

  • Lingering moisture caused by lack of ventilation 
  • Leaky pipes, taps and toilets seeping into plasterboard and wood
  • Damp cellulose materials such as grout, plasterboard and fabric provide the ideal breeding ground for bathroom mould

How to prevent mould in the bathroom

You can take a few simple precautions to stop mould from appearing in the bathroom. While these suggestions aren’t guaranteed to eradicate existing mould, they may help prevent mould from appearing in the future.

Open the window after a shower

Opening the window in your bathroom after you’ve had a shower will allow any excess moisture in the air to disperse naturally. Good ventilation can reduce the chance of condensation settling on the walls, ceiling, or around the windows, which can eventually cause mould.

If you don’t have any windows in your bathroom, consider investing in a ventilator fan or dehumidifier. This will have a similar effect to an open window, getting rid of excess humidity in the air after your shower.

Wipe around the shower

To help stop mould setting into your shower, wipe down the area (including  shower trays and wall panels) to remove any excess condensation that could turn into mould.

Add purifying plants

Some house plants can lower the humidity in the air, which can help break down existing mould and prevent more developing. Invest in one of these plants to improve air quality and reduce humidity in your bathroom:

  • English Ivy: English Ivy is a great choice for smaller bathrooms, as it can remove airborne mould from humid spaces. Plant it in a hanging pot or place it on top of a cabinet if you’re short on space.
  • Peace Lily: These purifying plants need very little sunlight to survive, so they’re an excellent choice for bathrooms without windows. However, peace lilies can be toxic to animals if consumed, so keep them out of reach from pets.
  • Boston Fern: Another great choice for humid bathrooms, the Boston Fern is an attractive, evergreen plant that thrives in indirect sunlight and moist soil.
  • Reed Palms: Found in some of the most tropical regions on earth, palms can keep humidity at bay in your bathroom by absorbing moisture through their leaves. Unlike other palms, the Reed Palm can survive in low light, so it’s perfect for keeping inside the home. 
  • Tillandsia: If your bathroom has a bright window, this is the damp-eating plant for you. Tillandsia plants thrive in filtered sunlight and absorb moisture through their leaves, so they’re great for combatting persistent humidity problems in the home.

Stick to a regular cleaning routine

Without a regular bathroom cleaning routine, bacteria, limescale and mould can become a real problem. Clean and dry your bathroom regularly, including grout and hard-to-reach corners that are prone to mould. 

Wash your towels and bathmats frequently, and hang wet towels and bathmats in dry, well-ventilated areas.

To further aid ease of cleaning and maintenance, our Wall Panel and Shower Tray ranges feature BioCote® technology to reduce bacteria and mould growth by up to 99.9%.

How to get rid of mould in the bathroom

Getting rid of mould in the bathroom is notoriously tricky, especially if you don’t want to use harsh chemicals. Firstly, you should identify what kind of mould you have, then assess how severe the problem is. This will help you choose the right products to remove bathroom mould effectively.

Black mould is one of the most common bathroom moulds and is usually the hardest to eradicate. It often appears in spots or clusters and can give off a musty smell.

Although unsightly, black mould is no more dangerous to your health than other types of mould unless you are allergic or asthmatic. Regardless of this, you should always wear rubber gloves and a face mask when tackling any mould in the home.

How to stop black mould in the bathroom

You can keep your bathroom mould-free by following preventative measures such as good ventilation, regular cleaning and introducing purifying plants to your space. But when black mould has already set in, there are a few things you can try to remove it:

  • Undiluted white vinegar is a simple and affordable home remedy for black mould. Pour vinegar directly onto the affected area or use a spray bottle to apply as soon as you notice black mould forming. However, vinegar isn’t as strong as bleach or specialist mould remover products, so it might not banish stubborn black mould areas.
  • Wondering how to remove black mould from silicone sealant or grout? Apply bleach to a cloth or old toothbrush and scrub these hard-to-reach areas. Be sure to wear rubber gloves and keep the bathroom well ventilated when using bleach.
  • If the first two methods haven’t worked, buy a specialist bathroom mould remover. These products contain strong chemicals, so it’s important to wear a face mask and keep a window open to avoid breathing in any harmful fumes. We strongly recommend wearing rubber gloves throughout the entire cleaning process to protect your hands.
If you opt for a specialist mould remover, take the following steps to remove mould from your bathroom safely and effectively: 
  1. Test the product in a small area first.
  2. Apply the mould remover as directed on the bottle. Many products need to be left for a certain amount of time to achieve optimal results, so it’s worth setting a timer to ensure the product works fully before scrubbing off.
  3. Rinse thoroughly and wipe with a damp cloth or sponge
  4. Repeat if needed until all the mould is gone.
