With autumn now well on its way, a bathroom expert has shed light on how to stop mould and moisture from building up in bathrooms – including at what temperature you should keep this room.

During cold spells, people tend to warm their houses artificially to maintain a comfortable environment for the family, with bathrooms being one room that is typically kept especially warm.

However, they are also occasionally ventilated by briefly opening windows – which can introduce cold air and increase moisture levels.

While warmth may be preferred, one expert is warning that keeping bathrooms too warm in the cold season can also lead to mould growth, posing risks to health.

Henry Maia, Vice President of Mineral Tiles and a home interior expert, has stressed the importance of setting the right temperature in bathrooms to prevent mould. 

He said: “Mould thrives in damp and humid environments. By maintaining a consistent and appropriate temperature, homeowners can make life tough for mould spores, protecting both their health, and the quality of their homes.”

Henry argues that the ideal temperature range for bathrooms is between 68°F and 72°F (20°C to 22°C).

He said: “Keeping your bathroom within this temperature range can help reduce the chances of mould growth. A consistently ventilated bathroom will minimise moisture accumulation, too, and that’s essential in combating mould.

“So instead of opening the window wide for a short while, it’s better to ventilate more subtly with small air vents or a window left open a crack for several hours – perhaps during the day when the bathroom is used less.”

Henry Maia’s top tips for warm and mould-free bathrooms in winter:

• Use exhaust fans during and after showers to reduce moisture
• Seal cracks and gaps around bathtubs, sinks, and windows
• Use space heaters wisely, making sure it’s placed away from water sources and has safety features turned on
• Use a hygrometer to monitor humidity levels – aim to keep these below 50%
• Use towel warmers
• Keep the bathroom door open when it’s not in use as this will allow fresh air to circulate.

He added: “Protecting your home against mould is not just about aesthetics – though that’s important; it’s about family health and safety.

“By taking proactive steps to manage temperature and moisture, homeowners can maintain a clean and comfortable living environment throughout the winter months.”
