1. Perfume
It’s convenient to keep your perfume in the bathroom, but this is a big mistake. Even the most expensive fragrances can turn sour if exposed to the heat and humidity from your shower.
High temperatures alter the perfume’s chemical structure, resulting in a sharp, acidic smell. Instead, store your perfume in a box, away from direct sunlight and humidity, especially not in the bathroom. Keep it in a drawer instead.
2. Mop
Many people leave their mop on the bathroom floor after cleaning, which is often a damp and poorly lit place. This provides an ideal environment for bacteria and mold to thrive, turning your mop into a health hazard over time.
Suggestion: Always wring out your mop after use and let it dry in the sun or hang it in a well-ventilated, dry area.
3. Toilet Cleaners
Storing toilet cleaning products, such as bowl cleaners, floor cleaners, and air fresheners, in the bathroom can be detrimental to your health. In a humid and enclosed space, these chemicals can release toxic fumes, affecting your respiratory system and skin.

4. Face Towels
It’s common to hang face towels in the bathroom for convenience. However, the high humidity, lack of sunlight, and constant exposure to wastewater and its bacteria can make this a less-than-ideal practice.
Used towels are often still damp, and if left in such an environment, they become a breeding ground for bacteria. Using these towels then transfers bacteria to your skin, increasing the risk of skin issues such as inflammation, rashes, and acne.
