Look for a 'bar' sink.

Sharp corners are very hard to form in drawn sinks.

For sharp corers you must weld up, and then deal with heat treat issue to restore the 'stainless' property.

Not cheap.

And sharp corners are harder to keep clan.

I have a 30" Krauss sink in my kitchen with small radius corners that I really love. If Krauss made a small square version, I would buy that, but their smallest is 20"x23". There must be something.

I am getting the Kraus farmhouse 33" sink and was looking for a prep sink with the near Zero radius corners to fit in a 21 " cabinet. So far I am between a Nantucket 15"x 18" or Lavello 15"x 20".... but both are the zero radius corners. Haven't found anything to work for me with the near zero corners.

Would love to hear what you find!

Maybe something like the Ruvati RVH7110? Not exactly square (18"x14" exterior/16"x12" interior).

There have been several recent posts regarding the Ruvati brand.
