There is a difficult to identify smell in my bathroom. It smells bitter, like paint or off-gassing rubber and is most noticeable in the red area shown in the pic. The smell is unlike sewer gas.



The faint odor is unnoticeable when the ventilation fan is on.

Check around the bath, could be mold underneath the bath or behind the tiles if there is a leak somewhere

Does it smell bad all the time or only when you pull your trousers and pants down?

Find the source of the smell and solve that then get an ozone generator and kill whatever is remaining.

I had something just like this, it was mold/rot under the bath tub area from a leak around the tub flange (very small leak), the bathroom fan just makes a vacuum in the room with the door shut and there was air being pulled up from under through gaps in the baseboards and floor etc

Check the duct for the vent, I discovered one recently that had a big sag in it inside the attic space, there was literally about a gallon of musty stink water in the bottom of the sag from condensation. Of course I found it by pulling the duct down out of the ceiling, through the hole where the fan was, and received a blast of stink water in my face

Could there be a build up of chemical cleaning product anywhere? Or leaky bleach bottle whatever?
