If your toilet bubbles while taking a shower, it sounds like a line problem. You will need to snake from your clean out pipe. If this does not work a professional needs to be called in. Your sewage may be clogged at the street which means calling the city sewage plant. If you need to call a professional and you are on city sewage you should call the plant to see if you need to call a specific company to help. My city's sewage insurance only covers certain companies. Good luck. :)
