How can I effectively address the excess gap in my bathroom fan replacement project?

Hey there, smart folks,
I’m currently in the middle of swapping out my bathroom fan. The old fan was 10 1/4 by 10 1/4, but the opening is actually 12 1/4 by 12 1/4. I ended up buying a new fan that’s the same size as the old one. Now I’m just brainstorming how to handle the extra space around the edges. Any suggestions?
You have the option to enclose it with drywall and attempt to match the paint, but it might be simpler to find a new fan or at least a different cover for the fan you purchased. Alternatively, look for an escutcheon that fits the size(s) you require.
Frame the interior shorter and use a type of window molding to frame it.
Enlarge the area to reattach the drywall to the studs. Replace it with new drywall and cut a new opening for the fan. Apply texture (knock down) before installing the fan. Lastly, prime and paint the area.
Based on the pictures, it seems like the fan cover will indeed cover the gap. The dimensions are 13 by 13 inches.
Add lattice material as a frame for the cover to lay on if it doesn’t cover the gap. Use spray foam to fill the gap. It’s best not to patch the skip trowel ceiling. Before installing, paint the strips and secure with liquid nails. Remember to caulk the sides of the skip trowel.
Measuring 13”x13”, the cover is big enough to conceal the opening.
Fill in the gap with foam, place the plate over the entire thing, and you’re all set!
‘t worry, the cap will be covered by the cover and everything will be okay.
