Odor from bathroom whenever upstair neighbor takes a bath
I posted the same msg in Bathroom Forum, but figured this is probably a better forum for this question. I'm living in the second floor of three floor building. Whenever my upstair neighbor took a bath, I can smell the odor from the bathroom. I can't really pin-point where it is from, and the odor isn't bad, but smell like soapy water. There was a leak about 6 months ago from their bathtub, but since then they had fixed the issue. Do you think it's from my bathtub drainage, trap issue or there is a potential leak?
