Yes, you can install an acrylic liner, but it's still costly and it only covers up your bathroom problems.
Compared to all that, refinishing your tub looks pretty good.
Refinishing Your Bathtub
Refinishing is either a do-it-yourself project or a hire-the-pro project. Porcelain, fiberglass, and cast-iron tubs can all be refinished. The tub does not need to be removed and taken to a shop. It can be done on-site and with a minimum of mess. The tub is primed, sealed, and painted with a highly durable, glossy top-coat of any color you choose.It is not a duplication of the tub's original dip-coat. The tub was originally dip-coated at the factory (But if you don't care about costs, it is possible to send the tub out for dip-coating).
What makes this such a valuable service, though, is the fact that it really does work. And when it's done, it looks nothing short of magnificent.
