There are so many reasons that they are a necessary item. Have you ever tried to blow dry your hair in a steamy bathroom? If you could see yourself in the mirror it might help, but with all that moisture in the air it's not likely.
Then there are also those unspeakable bathroom odors that almost anyone would rather not speak of, but they go along with the natural procession of things and the exhaust fan is a marvelous invention, if only to dispel an unpleasantness that remains even after its last occupant is gone!
A bad hair-do will be the least of your worries if the moisture problem is not corrected.
A consistently steamy bathroom can result in shrinking the edges of wallpaper and peeling paint.
These minor complications are bad enough in themselves, but with prolonged exposure, it can actually cause wooden window frames to swell, preventing them from opening easily, or not at all. Other wood, such as door frames, crown molding, and baseboards can swell and be damaged also, and then there is the scary mold that can grow on the ceiling and walls.
It can be much cheaper in the long run to install exhaust fans rather than wait around for more costly repairs to show up later. Rest assured, any unresolved water problems in a home will not result in any thing good.
The exhaust fan is something that is rarely overlooked in newer homes, but not so in older ones. If you are a do it yourselfer, this could be a project you can handle.
However, it does involve some electrical wiring, cutting holes through your ceiling and possibly through your outer wall in the attic. Home improvement stores have them with or without lights. If there is any existing light fixture in the ceiling of your bathroom, it is an advantage. If not, it will be a little more involved.
In any case, if you are not familiar with electrical wiring and reciprocating saws, then hiring someone to install it for you might be the easiest and safest option. Saving money doing it yourself is great if your work is done properly. Just remember it is only home improvement if you are fixing old problems and not creating new ones!
