We purchased our house about a year ago and since we have moved in we have had a sulfur "rotten egg" smell in the shower of one bathroom. All other areas are fine. We turned up the hot water heater temperature and that helped although it is still there.

In the last few weeks I have noticed on several occasions a methane smell in the bedroom cedar closet that is on the other side of the shower. Do you think these smells are connected? Any ideas as to what they might be?
