Ok, you’ve convinced me to do this the right way and relocate drain to center and complete a mud shower pan. I do have a couple more questions...
I have the old tub drain which has a p-trap below. Do I need to remove old p-trap and install new p-trap below centered drain location rather than just straight line pipe to existing location?
Also, to cut concrete, I have 4” angle grinder and porter cable circular saw. I see conflicting instructions on best way to cut through slab.
Any suggestions? Here is my existing drain line...
