Bars of soap.
Some say bar soap harbors germs. We’re no scientists and wouldn’t like to comment, but we do know that bars of soap make a mess.
Medication.
The humidity and fluctuating temperatures can interfere with some medications, possibly making them less effective. Don’t take that chance.
Jewellery.
If you keep your jewellery in the bathroom it will need cleaning more often to look its best. Some may oxidise and be permanently damaged.
Make up.
Keep your makeup at room temperature and away from humidity.
Towels and linen.
Don’t increase the risk of your towels and linens smelling foisty. Your bathroom is where you are most likely to suffer mildew or mold. Keep them somewhere dry.
