can you get a pick of the drain from above and below?
ok do you have access to the underside of the shower?
Well, unfortunately to solve the leak, the drain will have to be taken apart from underneath and re-installed.
lol, no sir. I don't think my wife would appreciate that much.
Sorry for the bad news, I just don't want to tell you "maybe this could work" ideas, when I know the only real fix is a re-installation. The problem with anything you could apply to it at this point is that there is no way to get the surfaces clean enough to properly adhere.
You can try marine grade caulking, its sold at home depot. it takes about 3 days to properly cure, but its made for boats. You need to be very careful with cleaning the joint. Thats the best I can tell you.
But once again, a re-installation is the only "real" fix
