Trying to get a cause and remedy.. I have a stall shower in a bathroom, after each use there is an odor that can be best described as sewer gas, this odor leaves the bathroom and permeates the entire lower level of my home, I have tried clorox, which helps for a short while, then it returns... Should I have this drain professionaly cleaned, try a specific product, or what... There is no odor when the shower is not in use. What can the reason be for this situation,
Thanks very much in advance for your assistance.
