We have tried twisting both ways, pulling etc. No screws visiable. Sorry for awful photo, it's pitch black in the bathroom now!

I see what appears to be threads at the top of the cover/diffuser. A counter-clockwise turn should remove it. I also see paint and drywall mud that MAY be preventing you from turning the diffuser.

  • Also, I would try to heat it a bit with hair dry fan - this could help against paint (by softening it) which could be on the thread as well.

The glass part should screw off from the metal part.

If it's stuck, try tapping the glass sharply (as hard as you dare!) with the handle of a large screwdriver, or something similar, while you try to twist it.

It might help to wrap something like a leather belt tightly round the glass, to get a grip on it all the way round.

Be careful if it seems like you are unscrewing the metal part from the ceiling. If that starts to happen, there is a chance you will short circuit the wiring inside and trip the breaker on your house lights when you try to switch this one on.

    Better yet, switch the breaker off before starting... and hope a second branch circuit isn't along for a ride in the box.

  • Be sure you're wearing good fitting safety glasses/goggles before striking the glass cover or putting a lot of force on it either by hand or with a strap -- wear leather or other protective gloves if you're going to apply a lot of force with your hands just in case the glass breaks.

Try turning it counter-clockwise instead of clockwise like someone suggested before. Also, try to get the glass of first, and then the rest. It seems like you're just having issues with the ceiling :( If it's stuck, maybe try to push it out with something flat and sharp. Maybe a knife would get it moving?

  • Sorry, I should've read alephzero's comment more thoroughly, I didn't realize that I was saying pretty much the exact same thing as him.
