This one simple storage mistake is causing toxic mould in your bathroom

-an uninvited intruder that flourishes in steam and low light. More than just an eyesore, it can also spark allergies and aggravate respiratory problems if ignored.

An expert has suggested a common habit that could be breeding toxic mould. Although it might appear convenient, storing toilet paper in the same warm, humid space where you shower can actually compromise hygiene and potentially impact your home's condition, the experts have warned. Toilet rolls are naturally highly absorbent, making them prone to soaking up moisture in the air-especially in steamy bathrooms after a hot shower or bath.

The issue is even more pronounced in poorly ventilated spaces, such as bathrooms without windows.

Sarah Day, Storage Expert at said: "For many of us it might seem the most practical and logical space to store spare toilet rolls is in the bathroom, after all, no one wants to be caught short at the end of the roll."

Over time, this lingering dampness can cause spare rolls to become soggy and, more concerningly, develop mould spores.

The risk is greater when toilet paper is stored in bulk on the floor or tucked away in enclosed cabinets that trap humidity.

Once mould sets in, the toilet paper is no longer sanitary to use and may even release allergens into the air, potentially affecting indoor air quality.

However contrary to popular belief the bathroom is actually one of the worst places for long-term storage for additional rolls of paper other than the one currently in use.

She explained: "This is because damp and enclosed environments can quickly ruin tissue-based products not only making them unusable but also contributing to hidden mould build-up.

"If you don't have a bathroom with proper ventilation or at the very least storage off the floor, you're actually far better off keeping spare toilet rolls in a dry airing cupboard or hallway cabinet and restocking the bathroom as needed."
