Hi. Thanks for asking. That is a custom trough sink made by our countertop fabricator. So the best way do this would be to find a solid surface countertop fabricator who has experience doing such things. As far as color, it can be whatever you select. That was a quartz material.

MRF construction - do you have to know the quartz manufacturer and color?

Caesarstone, Concrete. It's been a couple of years so I am not sure if that is still an available color. Good Luck!
