Mould in the bathroom is a problem that many homeowners face – or worry about. From unsightly stains on grout to the potential health risks of mould spores, the issue really does keep people up at nights. Bathrooms are particularly vulnerable because they’re constantly exposed to moisture, making them the perfect breeding ground for mould and mildew.
Is there any good news here? Luckily, yes. You can take some simple steps to combat bathroom mould and prevent it from coming back. In our exclusive guide, we’ll explore how to stop mould in bathroom spaces with actionable tips and long-term solutions.
1. Improve ventilation with an exhaust fan
Poor ventilation is probably the main reason mould thrives in bathrooms. Installing an exhaust fan is a game-changer for reducing humidity and preventing mould growth.
Why it works: Exhaust fans help remove excess moisture from the air after showers and baths, creating a less hospitable environment for mould.
Quick tip: Make sure the fan is vented outside, so that moisture doesn’t just accumulate elsewhere.
If you’re wondering how to tackle poor ventilation, contact a professional electrician to install an exhaust fan professionally.
2. Wipe down wet surfaces after use
An even simpler way to at least start to prevent mould is to remove excess water from surfaces in the bathroom.
What to do: Use a squeegee or towel to dry your shower walls, glass screens, and countertops after every use. It’s a hard habit to get into, but once you start – it can even become a fun post-shower routine!
Why it works: By reducing surface moisture, you deprive mould of the damp environment it needs to grow.
This step is particularly effective in preventing bathroom mildew on tiles and grout.
3. Use a bathroom dehumidifier
Ventilation alone isn’t really enough. So consider adding a portable dehumidifier to your bathroom.
How it helps: Dehumidifiers pull excess moisture out of the air, making it harder for mould to develop.
Pro tip: Choose a compact, energy-efficient model that fits your bathroom’s size and runs quietly.
A dehumidifier can be an excellent option for those wondering how to keep bathroom dry, especially in areas with poor airflow.
4. Opt for mould-resistant paints & materials
The materials you use in your bathroom can make a big difference in mould prevention.
Paint options: Use mould-resistant bathroom paints on walls and ceilings. These paints contain antimicrobial agents that inhibit mould growth.
Grout & sealants: How to stop mould in shower areas? Choose mould-resistant grout and caulk to protect areas like your shower and sink.
This is a great strategy for people asking how to prevent mould in bathroom spaces, as it provides long-term protection.
5. How to prevent mould in shower areas
Showers are one of the most common places for mould to form due to constant exposure to water.
Tip 1: Leave the shower door or curtain open after use to allow airflow.
Tip 2: Use mould-killing sprays weekly on tiles and glass.
Tip 3: Clean the drain regularly to prevent clogs that can cause standing water.
Dealing with mould in bathrooms? Focusing on your shower is a great place to start.
6. Focus on grout & shower seals
Grout and seals are highly porous and can trap water, making them prime spots for mould.
Preventive measures: Apply a grout sealer annually to create a barrier against moisture.
Regular maintenance: Scrub grout lines with a baking soda paste to remove existing mould and mildew.
For those wondering how to prevent mould in shower grout, sealing and cleaning are the most effective strategies.
7. How to prevent mould in bathrooms without windows
Bathrooms without windows can feel like a losing battle when it comes to mould, because simply opening up that window can do wonders for getting rid of the damp. But: there are effective solutions.
Install adequate lighting: UV light can help kill mould spores, so ensure your bathroom is well-lit.
Use plants: Certain houseplants, like Boston ferns, can absorb moisture from the air naturally.
Ventilation alternatives: If an exhaust fan isn’t an option, a dehumidifier is an excellent substitute.
This advice is perfect for addressing how to prevent mould in bathroom without window challenges.
8. Keep your bathroom dry, but also clean
Consistent drying, but also regular cleaning, are key to mould prevention.
Weekly routine: Clean all surfaces with a mould-inhibiting cleaner, focusing on high-risk areas like sinks, showers, and tiles.
Dry towels: Hang wet towels outside or in a well-ventilated space to prevent lingering moisture.
Regular maintenance is essential for reducing bathroom mould and preventing a mouldy bathroom.
9. Inspect & repair leaks
Leaks are a major contributor to mould problems.
Common areas: Check under sinks, around the toilet base, and behind the shower for any signs of a water leak.
What to do: Fix any leaks immediately to stop water from seeping into walls or floors.
If you’re dealing with recurring mould, hidden leaks could be the culprit, especially in cases of stubborn bathroom mildew. Contact your friendly local plumbers for help as they have the tools and expertise to detect hidden water leaks.
10. Upgrade to ventilated storage solutions
Even bathroom storage can contribute to mould if not properly ventilated.
Better options: Use open shelving or wire baskets to improve airflow around your toiletries.
Avoid plastic bins: Opt for breathable fabric organisers instead of sealed plastic containers.
Proper storage helps reduce moisture build-up and ensures your bathroom stays fresh and mould-free.
