Hi, I am remodeling my bathroom, I removed the 40 year old tile shower and want to install a jetted tub.
The Drain is located in the center and need it move forward.
Do you think I will find a threaded joint just below the old shower drain? I want to add a street 90 and plum it forward.
I have removed everything down to the foundation and before I separate the 2 halves of the old shower drain thought I might be better off putting a monkey wrench on it to see if there is a threaded joint underneath.

What do you think?
