Bad smell in the bath room
I am noticing a bad smell in one of my bath room. It is very light during the day time. I feel that the bad smell is getting built up during night and when I open my bathroom door at morning , I feel it immediately. I dont see any leaks in the bathroom. It has a faucet, toilet and bath tub.
I stopped using the bath tub and the smell is far less compared to earlier. When I used the bath tub, I could feel the smell the next morning. The plumber came and looked at the bathroom and said there is no leak. Not sure whether from where this smell is getting built up. Any ideas?
