  • Is this what you do after every shower? Then you need a new exhaust fan.

  • And since we're renovating everything else in this bathroom, there's no better time for

  • us to replace the old one.

  • The latest fans are so cool. Some have lights, some have heaters, and for the ultimate fight

  • against mold, some have automatic humidity sensors like this one. It turns on when it

  • senses too much moisture.

  • When you're picking out a new fan for your bathroom, there are a few things you need

  • to check out before you buy. Pay attention to sones and CFMS.

  • Sones will tell you how loud a fan isthe higher the number the louder the fan. 2 is

  • considered quiet. And CFMswhich means cubic feet per minuteis a measure of airflow.

  • The larger the room, the larger the CFM number. For a powder room, 50 to 60 CFM should be

  • enough. For a medium-size bath, 70 to 90, and for a large master bath go with 100-plus

  • CFM.

  • Also, if you want to make life a little easier, make sure your new fan will fit where your

  • old one already is. Remember, you can always pull out your old one and take it with you

  • to the store.

  • So to do that, first cover the work area with a drop cloth. Then turn the power off to the

  • old fan, pop off the cover, and double check that the electric is off. Next, remove the

  • motor, and take out the mounting screws. Slide the housing to the side and disconnect the

  • vent duct. Then, pull down the housing, disconnect the wires, and remove it.

  • Once you have your new fan, be sure to read the directions. Now, if your new one is not

  • the exact size of your old fan, it's ok. You can make some adjustments.If the new fan is

  • smaller, you can patch the ceiling. You can see how patch drywall at Lowes.com/HowTo.

  • If the fan is too big for the ceiling, hold it up to the hole, mark it, and cut with a

  • drywall knife.

  • With the hole squared away you can start hooking up the new fan.

  • Set the duct connector in the ceiling, hold the housing up and slide the connector into

  • the slots. With the housing level and perpendicular with the joists, drive screws into the joists.

  • Now head up to the attic.

  • If you need to, you can lay a board across the joists so you can kneel down. Attach the

  • brackets to the joists. Then connect the brackets to the body with a screw. And then attach

  • the ducts to the connector with HVAC tape.

  • On to the wiring. First take off the junction box cover. Then connect the house wires to

  • the fan wires.

  • Replace the junction box cover, and turn on the power. If it sounds loud like something's

  • not right, turn off the power and make sure everything's mounted securely in place.

  • When it's all good, add the mounting springs and push the cover into place.

  • Another project off the list. For more videos from this bath remodel series, visit Lowes.com/HowTo.
