re: Sewer gas smell from Bathtub drain

I had that problem in a half bath. Turned out to be a cracked flange on the toilet. Was allowing gas to escape. Replaced it and new wax ring and all good.

We had a similar problem in our hall bathroom area. Some days the smell was in the bathroom, other days it was in the hall area.
We put water in the sink and bath tub, but still had the smell some days. This went on for a couple of weeks. About 10 years ago, I had put in a new wax seal on the toilet. After a close inspection of the floor around the toilet, I saw a little brown on floor.
When I pulled the toilet to check the seal, I found about 1/2 of the wax was missing. Installed new seal and no more leaking gas smell.
