Steam, humidity, and condensation in a bathroom can cause a
number of issues such as warping fixtures, blistering paint, and allowing mold
and mildew to flourish. The best way to prevent these issues is to aerate the
room with a bathroom ventilation system.
Bathroom ceiling fans are the most effective ventilation
system, but it is important to choose the right one for your home. Bathroom
fans are rated by CFM – how many cubic feet of air they can move in one minute.
To determine which size is right for you bathroom, simply multiply your room’s
square footage by 1.1. A fan’s CFM rating will be printed on its outside box.
The best place to install a bathroom fan is in between the
toilet and shower. To ensure you are not harming pipes or wire, first drill a
reference hole with a small drill bit. If you are installing in a lower-level
bathroom, gradually make the hole larger until you can see what’s above. For
upper level restrooms, crawl into the attic to remove insulation and ensure you
are not too close to pipes or wiring.
Once you are sure you’re clear of obstructions, measure the
fan’s intake port to determine what size hole to cut in the ceiling. Using a layout
or framing square, draw the outline of the intake vent onto the ceiling. Be
sure to use the reference hole as a centering point. Using a jigsaw, drywall
saw, or reciprocating saw, cut the section out of the ceiling. Be sure to wear
goggles and a facemask to prevent injury, and always support the waste piece
before making final cuts to ensure smooth lines.
Once the hole is cut, your bathroom fan is ready to be
installed. Instructions for proper installation and wiring should be included
with your fan.
Please note: To prevent moisture-related problems such as
mold, your bathroom ventilation system must vent outdoors. Pushing moisture
into your attic or an upper level may clear the bathroom, but can cause rotting
of support beams and other structural issues.
