How do I cover this hole in bathroom ceiling? Pic included
DH had to cut this hole to install this ceiling fan in the bathroom in this 1940s home. How do we cover it up? DH just wants to put floor trim around the vent but I won't allow this. It needs to be done right. He says there's no way to wedge a piece of ceiling tile up in there but I'm not sure. What would you do?
Is it possible to buy these ceiling tiles (they aren't tile, they are some type of very lightweight material) in hardware stores or were they been phased out decades ago?
I was thinking that if we could get one, we could remove the vent fan's grate, then remove the tile that is there, and cut a new tile to fit and put it around the vent fan, then re-install the vent fan's grate.
Sorry if I'm using incorrect terminology. This is my first remodeling experience and I'm a total newbie.
