Help replacing bathroom exhaust fan on plaster wall
Hello everyone,
I'm replacing my bathroom fan on a plaster wall for a slightly bigger one so I have to open the hole up maybe another half inch all around.
Can I get this done without getting into plaster work? Are there fasteners I could use on the existing plaster to hold the new housing in to make this work?
Thanks in advance!

Welcome to the forums.
I'm not understanding - you need a bigger hole, how is some kind of fastener going to solve that problem for you?

Sorry stickshift. I wasn't clear. It's 2 separate things. First I have to open the hole a bit. Then I have to get the housing to sit in there. The fastener question has to do with fixing the housing in there after the hole is big enough.

Is that fan even rated to be wall mounted, looks like a ceiling mount to me.
That style is made to be nailed or screwed to soild wood.
What's the plan on connecting it up to the exhaust hose?
A Roto Zip with a tile bit or a 4-1/2" right angle grinder with a diamond wheel will open it up 1/4 on each side.

Thanks joecaption.
The fan is designed for wall or ceiling. There is a duct inside the wall that connects to the shaft that vents out the top of the building. The fan comes with a plastic duct that will connect to that.
I don't know how to fix the fan to the wall opening. I think previsously someone just plastered the previous fan into place. I don't know if I need to build a wood frame in there somehow or if I can use special fasteners to hold it to the plaster that is there already.

After you make you hole the size you need, take some 2x material and screw/glue it to the back side of the plaster on the edges where you want to attach the fan. (power grab or some other construction adhesive works well) Remove the fan from the housing, make your electric and venting connections and put the box in the hole. Screw the housing to the 2x material through the side. You may need to make your own holes.
