          In my experience the main cause of the septic odors you describe is a failure in the waste pipe venting system. You need to ascertain that the vents are working correctly. It is significant that your bathroom is on the second floor, since septic odors there really do implicate the vents.

            Maybe the work you had done on the drain was done in corectly and the person did not put in trap, can you see water in bottom of pipe when you shine light in it. If you have atrap there then the smell should be comming from the piece of pipe from top of shower to top of water in trap. Try some CLR and a brush and swab out pipe best you can.
