Problem with bathroom odors

[gmc444]

Hello,

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 correctly.

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.

Thanks,

Greg

This may have many causes. I suggest you go to a company that specializes in
plumbing and odor detection. Many companies have it and deal with it. If you
do not know much about odor detection, check the National Institute of Health
(NIH) right here: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3231359/ and
check out a local plumber like this one:
http://www.jwoodsplumbing.com/odor-detectionsmoke-testing.html . These are
just a couple examples. If you just google "city + odor detection" or "city +
smoke detection", because sometimes "smoke detection" is similar to "odor
detection", you should find the results you need to solve your problem. It
seems like your problem may take too much time to solve on your own, so you
should seek professional help.

Why don't you make use of some refreshing odor spray?
