Two questions about existing cast iron tub in remodel
We are gutting and replacing our 1960's 5x7 "master" bath in 2 weeks. The only thing we've been planning to keep is the cast iron tub because it's really in good shape in the interior.
However, there is a line of rust between the apron and the ledge (I included a photo below - it's difficult to see but you can tell there's a dark link on the side of the tub - that's the rusted area).
I bought Bar Keeper's Friend, but the rust is more than a stain, it's built up. Does anyone have an idea of how I can try to remove the rust in this tight spot?
My second question is about the drain and overflow - can I or should I replace these since the walls will be out?
We are buying all materials and the contractor is doing the labor. I haven't asked him this question and don't know if it might be a code requirement as well???
Any advice is appreciated.
