If a tub has already been glazed and now it's chipping a bit, can it be reglazed? Or will it have to be sanded and then glazed? How much does this type of thing cost?

You can have a pro come in and do a reglaze but it is more of an epoxy paint than a true glaze which is fired. You can try with a kit from the paint store but I have never met anyone who was very happy with the result. Etching not sanding is how the prep starts. A pro may charge you around $200. You can do it yourself for about $40 and then call the pro when you don't like what you see.
