Should I Get My Bathtub Refinished?
I give mixed reviews to tub refinishing.  I have had many tubs and surrounds refinished as opposed to replacing the units. Even though a good refinishing job is not cheap, usually around $300-$400, it certainly is less expensive than the labor involved in removing, framing and installing a new tub and surround. I have found a good sub-contractor for these jobs and the difference between a good long lasting job and a so-so job is in the prep. One sub I used years back did not take the time to really clean, sand and prep the surfaces before spraying the epoxy finish, had some problems and call backs within 2 years. I have a few jobs out there over 5 years old now, with no problems or complaints that my current sub has done, and done well. So I guess the moral of the story is, a refinish job can be a good long lasting solution if done properly with good materials. Side note: Don't wait until the original finish is worn to the cast iron. When rust is present, it makes refinishing more difficult and expensive.
