Bathrooms with showers are prime candidates for bathroom exhaust fans.
Bathroom exhaust fans are very important pieces of equipment for maintaining a happy and healthy bathroom environment. These fans help evacuate unwanted odors from the bathroom more quickly than just relying on the normal flow of air within the home. Bathroom fans also help keep those odors localized inside the bathroom. Another benefit of bathroom exhaust fans is mold reduction. Bathroom fans help to keep the humidity inside the bathroom under control so that mold growth is minimized.
Instructions
1. Locate and mark the proposed location of the new bathroom exhaust fan on the bathroom ceiling. The fan should sit between two of the ceiling joists and adjacent to at least one ceiling joist. Some manufacturers include a template for positioning and cutting the hole for the fan.
2. Use the drywall saw to cut the exhaust fan hole in the bathroom ceiling. Take the exhaust fan up into the attic. Using screws, mount the exhaust fan to the ceiling joist adjacent to the hole so that the fan intake is directly over the hole.
3. Shut off the power to the circuit feeding the bathroom at the main power panel. Find an electrical box on that circuit to take power from. A good option is to extend the circuit that handles the bathroom lighting. This would put the fan on the same circuit as the light switch. Extend a piece of Romex 12-2 wire from the exhaust fan to the lighting fixture electrical box. Strip 1/2 of an inch of insulation off of the black and white wires.
4. Connect the black and white wires of one end of the Romex cable to the corresponding black and white wires in the exhaust fan. If there is a ground wire, connect it too. Add plastic splice caps to secure the connections.
5. Connect the black wire and white wire of the Romex cable to the black wire and white wire of the light fixture.
6. Turn the power back on and test the fan operation. Install and secure the bathroom vent cover.
