Reply to comment by Yummy-Beetle-Juice in Ceiling too short for exhaust fan by fancypanting

Another possibility is to install joists and bring the entire ceiling down.

If I want to go with the 5.25 inch tall fan, that would be too much right? Lowering by over 2 inches below the ceiling? Actually the hole isn't big enough for me to test placing the fan in place, but I'll enlarge it tomorrow (for the 4 inch tall fan).

The electrical I have managed to run through the hole along the joist to the other side of the bathroom.

Can you cut a hole through the sheathing that is nailed on top of the rafters? Is it the roof deck? If it is the roof deck, do not disturb it. Look in the attic before doing any work.

the bathroom is below another floor. I am not too confident to cut through the sheathing, fearing that it is the heating vent or something else important.

Probably not a good idea then. If the bathroom is on the first story, how are you going to run the fan exhaust duct to the outside? How are you going to run electrical?

the fan exhaust duct is already in place, it's outside the drywall so I have to later fix them in place and cover them up with plywood.

what do you mean how to run the electrical? I just take it from the living room?
