home improvement Help with bathroom fan install
Hey, looking for recommendations on how to fix my current DIY slog.
I needed to replace my bathroom vent fan/light combo, so, I purchased a new one of the appropriate strength for our small/medium bathroom.
Then I found out how much of a nightmare it is to get an old fan housing out without access from above (there’s no attic - the bathroom is in the converted attic, so the only “above” is the roof)
But, the hard part is done & the old fan & enclosure are out.
But now I find out that the old opening is 12” square, which is quite a bit larger than the new enclosure - that’s supposed to attach to the drywall. It’s even bigger than the cover.
I’m happy to exchange the fan I bought, but I don’t think there are many that are this large.
So, what do you recommend? Plywood frame set into the large opening? Patch the drywall and then cut a new opening? Recommendation for a fan/light that takes a jumbo opening?
Thanks so much for your help!
