I have searched all the questions in the odor in bathrooms, but none apply.
The house is 4 years old and ever since we moved in my wife has complained about the stinky bathroom. We have two bathrooms and only the one has this problem.
The smell is like sulfa coming from the toilet. My son was visiting yesterday and he complained of the smell.
I have inspected the tub and sink to make sure water is in the trap, and toilet, all ok. We have a vent in both baths. We have a septic system. The vent over the smelly bath comes streight up from the plumbing and only rises about 18" above the roof. We have a lot of wind in the area where we live.
