How much weight can a plaster/ceiling aupport
Drew

I am having my bathroom remodeled on a house that was built in 1928.  The last time the bathroom was done (30 years ago ?) they dropped the ceiling in order to add more insulation and left the plaster ceiling. I did not own the home but this is the best my contractor and I could figure.   I am having them raise the ceiling back up but they are leaving the plaster ceiling in place and putting drywall over it.  I have some shelves that I would like to hang from the ceiling and I was hoping they could add some type of wood backing or something for me to mount the hardware that the shelves would hang from. They are telling me I can just get some toggle bolts and go through the dry wall plaster and lathe and it will be supported just fine. The total weight if the items shelves and hardware will top out around 30 pounds. Will the ceiling be able to support this weight with two toggle bolts?

Drew,

Not sure why you would want to cover plaster. That is much better than sheetrock, especially in a wet environment. I would never cover plaster.

The ceiling covering is not supporting any weight, or better not be. The structure and sub-structure behind the plaster will be supporting all the weight. You may use a toggle bolt, they will hold just fine. Better if you use a lag screw and fasten it into a ceiling joist. What you may experience is that if you use a toggle bolt and break off some of the keys that the plaster use, it will no longer be properly supported and will crack. If that happens, you can drill small holes in the plaster and use some Plaster Magic products to secure it to the lathe behind the plaster.

Unfortunately there are parts where the plaster was taken out.  I attached a picture.  The framing that is showing is from the drywall ceiling that was ripped down and will be removed. I am just assuming that there will not be a joist Where I need to put them. If I get lucky and can use a joist I definitely will. I just wanted to plan for the worse or see if I would need them to add some sort of backing.  I also posted a pic of what they recommended I use if I do need to go the toggle bolt route.  If anybody recommends something different or agrees with what they said I should use it would be appreciated.

Drew, that is only a very small area, that can be easily repaired. It will be a shame, but you may also be money ahead if you tear it all out and start fresh. That way you will have a level area to fasten the sheetrock. I would leave the lathe strips to give the sheetrock something more to adhear to. Then you would have more than enough backing to install a lag screw or a toggle. Yes, we know what a toggle bolt looks like. I would not use the plastick toggle, I would use a metal one.
