Install a new Bathroom Fan

I bought a bathroom fan at Costco Warehouse at a discounted price.

Dewstop Bathroom Fan and Switch

After installation, it is so quiet that I can barely hear it.

The steps are simple. The work is not easy for me. The old fan is smaller than the new one.  So I need to cut the hole bigger. The pipe behind the ceiling is steel ductwork, not a flex pipe. So I have to move the cutout a little bit off to accommodate the space.

And some tiny jobs, including adding support, drywall patch, mud, painting, and replace the old switch to a new switch with the sensor.

Here are some pictures my wife took or I took during the two-day job.

Here is where I tried to tear down the old fan case. The fan was removed already.

This is the new Dewstop Bathroom Fan. I hold it.

I need to take the fan from the case to install the case. See the switch on the right side. I can choose 80CFM or 110CFM. I tried both settings. Even 110CFM did not make a lot of noise. So, at last I decided to use 110CFM.

The case of the new Bathroom fan is installed. The 1×2 wood is for a supporting purpose only. Oh, I added a vapor barrier sheet inside.

 

It is a test run, I installed the Fan and wires. To test the performance and everything is good.

Then I removed the fan and added the drywall to the ceiling. Fastening everything.

I patched the gap with quick mud.

To change the switch, I bought a new cover.

Removed the old one-gang switch. Install the new Dewstop condensation Fan switch with timer and moisture sensor.

I changed the default setting to 30 30-minute auto-off timer. Change the sensing moisture less sensitive. This switch is over $50 at Home Depot.

I put the cover on it.

Final work. I am happy to see it.

In the last picture above, you can see my effort to make the texture, or the orange peel ceiling. Not perfect, but I believe I tried my best.
