I live on the 2nd floor of a 3 floor co-op. Periodically (and twice in the last 2 weeks) there is a vile, "low tide" smell that eminates from my bathroom area. My bathroom is cleaned once a week, as it has been since I moved in a year and a half ago. I have only experienced this 3 times, 2 of which were very recent.
Not to be gross, but I literally smelled every surface, but can't find from where it is coming. Could it be a leak in the walls or ceiling? From the fan vent? Any suggestions? I am going to call my super, but I don't know if it is from me or elsewhere. Thanks.
