One perennial question for the consumer: refinish the tub or reline it?
Miracle Method's Don Dominick notes that at one point Miracle Method did consider entering the tub liner market. CEO Chuck Pistor even presented this issue at a Miracle Method conference. The response? Overwhelmingly negative. At that point, Miracle Method decided to table the idea of entering the tub liner market.
Bathtub liners have advantages--no odor, no danger of overspray--but they tend to be more expensive than resurfacing. Also, liners cannot be made for every single type of bathtub out there. What about that circa 1897 castiron tub of yours? Good luck...
But the worst part is the problem of water incursion. Since bathtub liners have a void between the liner and the tub, that void might invite water incursion. As the saying goes, "Water seeks its own level." With bathtub liners, we might change that to say, "Water seeks spaces under tub liners."
