I have a floor drain in a shower stall that I can't remove. I can't tell (see pictures) how the drain was attached. scrapeing away the grim around the drain pipe shows something metal, but it's very soft, and not un-screwable. I can't find any gaskets. How do I get this thing out? This is a very old shower stall (sheetmetal) and looks like it was installed as one piece, base and all. I don't think there is access to this part of the crawl space. What are my removal options. I do not plan on putting a shower back in, but I wouldn't mind a floor drain here.
Looks like a lead joint. See if that gray stuff around the edges is lead. It should scrape very easially with a screw driver or anything sharp and hard. The whole shower pan is probably lead.
If it is lead grab a drill and drill a bunch of big holes in it. You should then be able to dig out the lead and oakum with a screwdriver. You can then either cap the line below the floor or install a floor drain (so long as the pipe has a trap). If you install a drain you will need to periodically add water to the trap to prevent sewer gasess from coming up through it.
