I know you’re going to laugh, at least make snide remarks about rookies, but I need to ask anyway. Looking at doing a bathroom remodel, which will include moving the tub. I can take measurements and get the tub drain roughed in purty darn close to where it’s supposed to be, but I don’t see how you place the tub over the pipe and make the connection. First floor slab on grade, so there’s no access from below. Assume there’s no access from the end of the tub either, and it has an integral front apron.

If the slab is not cut away to give you access to piping, i.e. slab was formed with an opening down to the pea gravel, my suggestion is take the tub out, use a compressor and hammer drill and chisel the concrete off and then you can adjust your piping as needed in the pea gravel and rising up. The concrete comes up amazingly fast and controlled with a hammer drill.

Strong friends, shims under the tub you remove to lower it into position, and last of all you have to have an access hole on the drain end.
Otherwise I can't see how you'd ever service this thing. The tub drain alone has a nut on the backside, not to mention the overflow assembly. This needs to be sealed up and secure.
Patching drywall or even cutting block isn't that tough, you need access.
