Should I get rid of the original cast iron tub?

[Mehgan Moore]

We are currently living in a triplex and renovating our units bathroom. The original cast iron tub is in place and would look great with the classic retro reno we are doing. However the tub has already been resurfaced once and is peeling. My question is, would it be worth looking into a bath liner and keeping the existing original cast iron tub or replace it with a cheaper option such as steel or fiberglass? We plan on doing white subway tile all the way around the tub.

Thanks for any feedback!
