Replaced a ceiling mounted one that made the plasterboard vibrate with an inline fan. The inline fan is up in the attic and ducts through the roof. The new fan extracts 3x as much air and is much quieter.
Still need to make good the ceiling, but that’s tomorrow*'s job.
*Tomorrow in this case may not actually be tomorrow.
Reminds me of when I moved into my house. The bathroom ceiling fan in the master ensuite was so noisy and grindy I just hated being in there. I took the fan out and wiped off all the dust. Can’t remember if I greased anything but I probably tried something. Dropped the noise level so much and no more grinding.
If I ever replace it, there are some fans that have Bluetooth speakers built in. I might do that for some shower music.
The main issue for mine was that it resonated with the ceiling panels, meaning there was a loud vibration that could be heard in other rooms. The noise from the new fan is just the whooshing of the air, no vibrations at all, and when the door is closed it’s almost inaudible.
