Custom made.

Valspar's Prairie Dance is a similar color.

Thank you

Try Lightology.com - I think they have something similar.

It's tough to tell from the photo, but it looks like a solid surface material like Zodiaq or Caesarstone or Cambria

They aren't trough sinks, they are Ladena sinks from Kohler.

Kohler's Ladena has a definite ridge on the sides. These don't. Can someone confirm?

They sure look like the Kohler sinks to me - but you could always contact the designer...

I looked back to when I questioned the designer 9 month ago. And the designer responded that they are Kohler Ladena k-2215 undermounts. I hope this helps.

Toto also makes a couple sinks like this, both smaller than Ladena K-2215
