Bathtub dilemma

[LiberalEsto]

We have a 1967 pink bathtub that has seen better days. The surface has worn off in one spot.
My son-in-law is going to remodel the bathroom, including removing old tile and drywall, and putting up new water-resistant drywall.
We're hoping to find tile at the Habitat ReStore. We have limited finances.

I am not sure whether to replace the tub, have it painted with tub paint, or something else.

I've heard that tub paint smells horrible for days. But moving the old tub out sounds like a very hard job and I'm not sure if the plumbing connections will match up with the new tub..

I'd be grateful for any suggestions.
