Sewage odor coming from only master bathroom but is strong. No basement and on city water. No smell coming from any drains in master bath. We poured bleach down each drain, cleaned traps, ran water and can't remedy the situation. I smell the odor outside sometimes which makes me worried about cracked pipes. We live in hot climate so no risk of freezing or anything. Any ideas? Thanks.

Does your toilet rock a bit on the floor side to side? Could be a bad wax ring.
