We have good news and bad news. The bad news is your sink style is no longer manufactured. The good news is swapping it for a new model probably will improve kitchen working conditions. Be flexible, and your story will have a happy ending. Look for a sink which is at least large enough to cover the existing hole in your kitchen counter. This will save the cost of counter replacement. A larger sink will require enlargement of the hole left by the old sink, but that cost is minimal. Even ceramic tile can be trimmed back without too much effort.

As you shop, remember that length and width are not the only washbowl dimensions that vary. An inch or two or three in added depth can convert a typical kitchen basin to one almost as versatile as a janitorial-type deep sink.

Apparently you are concerned about drain size and placement, but we can advise that your new sink will look terrible with the old drain outlet reinstalled. The very best and most expensive ones run in the $30 price range and will last another 50 years. Drain location can be altered with a new P-trap configuration for under $20.
