I am hoping some smart person can help me with ideas for identifying odor
problems in my master bathroom.
There are two subtle odors involved, one comes from near the two sinks, the
other from near the toilet. Both are subtle. The one from near the sinks is a
kind of fermenting smell. The one from around the toilet is a sharp smell. They
do not smell like a sewer odor. Both odors are stronger when the weather gets
cooler and damp, and if one of the windows is open a bit.
Sinks first: it doesn't appear to be coming from the drain or the overflow. I've
cleaned both with several types of chemicals and cleaners. The p-traps function
The smell from near the toilet could be from the bowl, but it is hard to
pinpoint. We had it reseated last year, and there's a silicon seal around the
base that is intact.
I tested the all the roof vents using peppermint oil. No peppermint smell came
into the bathroom. I've checked the crawlspace under the bathroom. There is no
sign of leaks, and no unusual odors are present there. I checked outside the
house. There's a compost pile about 30 feet away, the odor is not coming from
there. Nor can I find any other likely source outside the house. Ive also
checked the attic above the bedroom. There's no unusual odor up there either.
The bathroom is new construction, completed about two years ago.
