I'm removing a fiberglass shower stall and the only thing holding it in at this point is the drain. It's a plastic assembly and it appears to attach by screwing in (I can lift the stall enough to see the underside of the assembly). How do I remove this type of drain assembly? The obvious answer is to unscrew it, but there is no way to get a hold of it.
Many of these pvc shower drains come with some type of key to screw it together. By key I mean a piece of metal that fits in a slot or between protrusions within the drain that you then use channel locks to turn and unscrew. They usually get tossed after a few years as no one remembers what it was. With the chrome cover off look for this. You can make a key out of an L bracket from lowes.
