I'm trying to take out a shower pan. I have the drain cover off but am having trouble with the drain itself. Everything online suggests that I need to drill some holes and shimmy the gasket out to free the pan from the floor.
But my drain has no such gasket. It seems like instead there is a soft metal, I can drill into it but have not had much luck loosening.
Does anyone know what this is or how I can remove it? The home Was built in the mid 80s and I believe the shower is original.
