 Cannot unthread shower drain.
Author: jaredneumann (UT)

Hi there, I am expieriencing a leak coming from below a standing shower, I know its coming from a bad seal between the two halves of the drain. Unfortunately the upper half of the drain has absolutely no place to grip to remove it. Its completely smooth inside. I may be able to loosen and tighten it from the bottom but its in a difficult to reach place so figured I'd ask here and see if anyone had any insight to this. I've included a link to some pictures of the drain, both top and bottom. Any help would be great!

Thanks for your time

The pictures of the bottom of the stall are the important ones, but they appear to be so dark, or confused, that they are useless. The drains typically do NOT "unscrew from the top". They normally fit through the base and the nut on the bottom makes them seal.

there is no such thing as a leak between the halves of a shower drain.
the leak comes from the top where the flange of the drain set ontop of the shower floor.
i can see a 6 or 8 sided nut in one of your pictures. that must be loosened so that hopefully the flange will lift upwards about 1/2 inch. you then need to cleanout all the putty from beneath the flange, dry it all up, put a good bead of 100% silicone caulk under the flange and tighten the nut below..
if you had clear access this is a semi-diffucult job. given the very limited access you do have i don't think it can be done without removing a bunch of stuff..
