Plaster bathroom ceiling missing

Hello,
We have a problem with our bathroom ceiling. The portion that is missing is due to a leak that was happening on the roof around the chimney. The previous owners paid someone to fix it, but it was not fixed properly. It leaked down and eventually ruined the plaster, and I'm assuming the lath that's up there too, which has been exposed for some time. I'm concerned about the steam from all the showers we've taken while it's been exposed. Well, my question is, how would I go about repairing this open space? Do I tear the whole ceiling out and replace with drywall? Can I just patch the hole with drywall then paint over it to conceal the seam? Thanks!

It sounds like the ceiling is shot. I'd remove it and start anew.

If you drywall the bathroom ceiling, you must use regular drywall, not greenboard.

I didn't know that. Why can't you use greenboard?

It has to do with weight when saturated. In bathrooms, the humidity and moisture will make greenboard much heavier than regular drywall, in fact so heavy, that there is a risk of it falling.

For the walls though, greenboard is perfectly fine.

Thank you for the tip! I'll do more research. I've never taken on a project like this!

What kind of material is the lath sitting on? Is it currently sitting on ceiling board (a type of drywall specifically used for ceilings)? Depending on the substrate, you may be able to just remove a portion and patch it.
