shower drain odor

Hi Terry: We have had an ongoing problem with what seems like sewer odors coming from our upstairs shower stall. They are noticeable only after warm water has been running in the shower for 5-10 minutes; the drainage is fine and no sign of backup. I have been putting chlorox in the line in the past to clear it up but it always returns; this may have done damage to the line since we recently had a bad leak from the drain trap. The plumber who repaired it said the line was made of copper and it was badly corroded with many small holes. He replaced it with a PVC U-trap. In any case, the sewer odor is still strong whenever the shower is used--any ideas?
