getting ready to install the fantastic fan into my wet bath. cutting in a 14x14 fantastic fan where my original round fan would be.

Any advice? what is best tool for cutting the hole? I have a nice bosch jig saw that usually makes easy work in these types of situations, but just wanting to hear about all the other options. I do not want to crack out break out the bath module plastic.

thanks,

Jon

Howdy Jon, I used a jigsaw, bath module cut first then drilled holes from inside thru the roof at the corners to get roof hole located. There are ribs up there so you have to miss them. I located ribs after taking the original fan out and poked the wires out of the way. One of our curtain rails needed moved over too. You will be a hero when the family sees how much light comes in. I glued wood strips on top the bath module so the trim would have something to screw to.

Here is how I did it.

my wife's FAVORITE upgrade. Her first sentence when she looked at our new Kingsley's bath was "You'll be putting a Fantastic fan in here won't you?"

I first used the trim piece to mark the location of the corners on the ceiling after pulling the round fan to watch for any obstructions or ribs. Then, drilling holes in the four corners that were marked made simple work of finding the appropriate spots to mark and cut the roof aluminum. I also used a small jigsaw with a metal blade to cut through the roof. I'm not sure if I cut the fiberglass with the jigsaw or if I used the Harbor Freight oscillating saw (aka the GMC tool) .

As with other's experiences, it makes all the difference in making the bath module much more inviting to enter.

It's scary work BUT it's easy enough to do (in hindsight) !

Put a couple of layers of tape on the flat bottom of the jig saw to prevent
scratching of your roof paintwork and the interiour fiberglass in the
bathroom.
That plus measure twice and cut once is my advice.

Good luck

Hello,

While I don't know if its any better then a jig saw, I used one of those double cut saws from harbor freight. It made quick and easy work of enlarging the holes for my fantastic fans. One note is that my 78 already had a 14inch opening in the bathroom so I just had to trim the corners. Just another option.

The HF oscillating saw would work fine. I used my hand snips because I had them. The top of the GMC is .063 aluminum.
