In one of our three bathrooms, we have a slight sewer gas odor.
But, even a slight sewer gas odor is unpleasant, so I need to fix

The odor is not coming through the shower or lavatory drains,

then not using this bathroom for two or three days, but the odor
remains. *The toilet bowl holds the normal level of water, so
I don't think it is coming up through there.

The only thing I can think of is the wax ring must have deteriorated,
although I have not ever heard of this happening. *Our house is
sixteen years old, and we have lived in much older houses, and
never had to replace a wax ring.

I don't think it makes any difference, but we are on a septic system
since we are outside city limits. *The system is working properly, and
has recently been pumped out. *This did not have any effect on the
odor.

I'm too old and stiff to tackle the job of changing the wax ring myself,
but wonder about how long of a job this might be since I'll hire it out.

All comments welcome and appreciated.

I agree, the wax ring could be yout problem. Before going there check
under the sink to make sure you don't have vent valves. Replacing the
wax ring on an old toilet would be an hour at most. It's not so heavy
if you take the tank off first. If you do that get a new tank gasket
too.
