How to fix floor cracks in bathtub (enamel?) coating

bathtub

We just moved into our new home (not a new build) and noticed flaking of the material in the bottom of one of the bathtubs. It appears as though the coating (enamel?) has flaked away in some places. We haven't noticed any leaking, but we're not sure how much of a problem something like this could be and we'd like to fix it before it becomes something bigger. Is there an easy way to repair this?

Most home centers will carry a porcelain touch-up paint. I have used it for chips but not for repairs as large as your photos show. Trying it won't make it any worse. As an alternative you can see if you it is possible to identify the tub manufacturer. It is possible that it still is under warranty. Several full scale repairs options are available with out replacement of the tub. One type involves installation of a specially molded liner that covers the entire tub. The other involves coating the tub with an epoxy like material. Neither of these are do-it yourself projects but generally are less costly than having the tub replaced. A local search for Tub-refitters should yield some results.
