Mold, Laundry Hampers, and Bathroom Vents
Something that has been popular in the past and even in a few homes now is putting carpet in the bathroom. This is a very bad idea, because no matter how careful you might be, your toilet, sink, or bathtub is going to overflow eventually and leave you with a mess of soaked carpet and padding. Carpet needs to be dried as soon as possible when it comes into contact with water. Once the water dries naturally, the carpet will smell, especially if you are unlucky enough to have to live with only well water.
If you live in an older home and your bathroom does not have a vent to release the hot air and steam outside so that it does not attach itself to the sheetrock and become absorbed by it. This is a worthy investment to make and it should not cost more than $50 to $70 and maybe half a day of time to install if you do it yourself.
Whatever you do, do not leave damp towels, rags, or clothing in the bathroom closet or on the floor, especially if you have carpet in the bathroom. Your best bet is to use a plastic laundry hamper and put the dirty laundry in that and only in that so that even if the clothes do become moldy, it is not likely to infect the floor or the wall because of the plastic barrier.
