The tub will plumb the same, the waste & overflow will be exposed of course.
Most old style w&o use a 1-3/8" tailpiece instead of the standard 1-1/2".
They make a slip-joint washer that goes from 1-1/2" to 1-3/8" for that purpose.
The flooring should be fine.

: Is there any special plumbing required in putting in a claw foot tub. We have purchased an old one and will have it sand blasted and painted. Will any extra floor support be needed also? Thanks so much
