The next step is you have to cut a hole in the ceiling larger than the finished opening, unless if you have access from above at your home, in order to get the fan housing into the ceiling and to attach it to the joist for support. To do this part of project, you can use a rotary cutting tool, like a rotozip or a drywall saw.
Recognize that it is a new installation; you have to find power for the fan. You will need to run one or more switched circuits to the fan location from your switch location. A single circuit is typically all that is needed for the fan, light and heat unit, if equipped. You will need to refer to another reference source for instructions on accomplishing this.
The next step is you have to find an exhaust duct, which is typically vented to the outside through the roof or through the side of the house.

If it has been done, you have to test the fan for proper operation by turning on power at the breaker and testing the switch. Once operation is verified, turn off power until install complete.

The first thing you should do is by cutting back the ceiling material (typically green board or drywall) so that you have a square or rectangle that has at least ½ of the ceiling joist edges on either side of the fan exposed to screw a new piece to.
Then you must cut a new piece of drywall/green board to fit in the enlarged hole and mark the location of the housing flange on the backside of the piece to cut out the opening for the fan. For your information, s simple method of doing this is to use an old lipstick to run on the edge of the fan housing. When you push the drywall against it, it leaves a nice cut line.
After that you must cut out the fan opening and hold up the piece to test the fit. Then, adjust as necessary. The next step is you have to Install the drywall using 1 5/8″ drywall screws along the ceiling joists and either drywall clips and screws or backer boards and screws along the unsupported edges.
The last step is you must tape and mud the joints. Now, install any bulbs in the fan unit, put on the cover and turn on the power at the breaker.
Well, now you have to know that how to install a bathroom fan is not as difficult as you think. What you should do is prepare your time and patience to do the project. Happy installing!
