The gage of steel is in reference to its thickness, and thereby inferring added strength and longevity. There's nothing wrong with 18gage stainless in my opinion, especially in light of selling the home within a year. Blanco and Franke are respectable options based on the information you're providing.

Was told to get 18 gauge blanco stellar sink
When I called company told made in china
Now is that bad?
Also called kohler said their products made all over USA or Mexico or china
Need to look on box to see where made
How can I order online to get discount and know I am getting made In USA?
So very confused at this point
What have people been ordering and does it really matter?

What kind of bowl configuration and installation type are you looking for? double bowl, single bowl, self rimming, undermount, etc.

Undermount single stainless
Cabinet under sink 36"
Sink in front of window 34x34

I would check out the Vault or Strive sink from Kohler.

Here is a pic of the Strive.

The strive I really do not want zero radius chart corners
Heard harder to keep clean
Will look at other kohler
My issue is u have no idea where made could be china
