Managed to set the tub in mortar today. I needed to use what's called a direct waste drain set up.... not enough space to rough in the p trap on the new center line, so, direct waste drain shoe. It's not often used in residential, so it isn't readily available locally.
It took a while to find one in stock locally, but we prevailed. Now I'm leak checking and waiting for the water weight te squish the morter.
