The drain pipe from bathroom sink and shower is leaking through the ceiling into the kitchen below. Can this pipe be replaced without breaking through bathroom floor?

If the faulty pipe's located inside a wall then the wall must be opened up. Since you've failed to identify the pipe in question or its location I can't answer your question but the chances are very good that something's going to have to be opened up to fix the leak. Good luck, Tom
