That old enamel-on-steel sink in the main floor "powder room" was showing its age (about 22 years). I touched up one chip (with a different colour as those "standard" colours change over the years) and a couple of weeks later a new chip appeared. So I replaced it with a shiny white porcelain job yesterday. As I had previously replaced the taps and the drain it was just a matter of loosening a few nuts, taking out the old sink, cleaning the vanity cutout and plopping in the new one. It's not "perfectly" aligned with the cutout: to do that would have meant cutting off the old drain pipe and rebuilding a new one. The caulking provided with the sink hides the slight gap anyway. I have gone away from using silicone caulking. Though it seals nicely, it's a tedious job of scraping to clean it off when you replace something. Plumber's putty and mildew-resistant latex caulk are much easier to remove and probably seal just as well.

Sometime in the near future I will have to replace the sink in our ensuite for similar reasons However, I will also need to replace the old taps and drain, too — not just an afternoon's bit of work and a job for another vacation period.
