Hi Sinkology, I need to order the Rockwell this week and would like to order a grid with it. Can you tell me when in March it they will be available? Thank you!

We don't have them yet, but we'll have them by the end of March.

We just got them in today! It'll take a few days to upload them, but we've got Rockwell bottom grids now!

Can you post the link please?

what are the dimensions of each opening?

This sink will fit any 3.5 inch drain and the bottom grids are 1 inch squares with a 5 inch square that rests over the drain. Hope that helps!

Sorry, I meant the bowls. Thanks for your reply

No problem, each bowl is 14 x 19 inches.

I am having trouble keeping my sink from getting black spots. Is there a certain cleaner I should be using?

Nope, just a bit of warm water with a few drops of soft dish soap such as Dawn or Palmolive and a soft cloth or sponge is all you need. You can remove the black spots with a dish scouring pad, like the rough side of a dish sponge, and let the living finish heal over the bright spots.
