Shower to cast iron tub drain swap

[Austinthies]

Howdy, I recently took on a job doing a house renovation and the owner had already taken the shower out and all I had to work with is the 2” threaded steel pipe with no floor around it.

My question is What may be needed to put a kholer cast iron tub back in the same spot the shower was?

The tub has no drain on it
The steel pipe connects to cast iron
The drain location cannot move
House was built in 1942 no basement no slab

so, crawl space? You would need a plumber, or send pics and you might get some off the cuff responses.
Steel pipe for drainage is totally obsolete, so the first thing to do is remove all steel piping completely and start over.

You need an opening to work from this would be on the other side of the wall the contains the faucet. There's no way to do it from above later. If they go with a claw for tub with integral overflow then it can be done from above later, but a standard tub need access from either below or from the end through the wall.

2" is the wrong size. The trap needs replaced.
