How to remove drain from fiberglass shower stall?
 

I'm replacing the stall shower but I can't figure out how to get the drain out. I don't want to pull and potential hurt the drain plumbing but there does seem to be a way to remove it otherwise. Thoughts?

I found this video which looks similar to mine. Do I need that special tool to remove it?

If you don't mind damaging that visible trim ring, make a notch in it with a chisel and then using the chisel at a low angle and a hammer, whack the ring so it wants to turn in a counter clockwise direction.

Thanks, did that with a screwdriver and it worked.

It also can be useful for removing crankshaft nuts that have been torqued to 250 lb-ft. when space is limited.

Sometimes a high impact torque works better than a low steady torque.
And if the ring didn't move I'd say give it only one whack first in a clockwise direction.

Glad it worked. :D
