One thing to keep in mind when selecting a secondary sink is the size of the sink you choose. I say no one has ever complained that a secondary sink is too large, but you will definitely notice if it is too small. That said, there is a limit to the sizes available for this kind of sink that comes off the shelf. You also are limited by the interior size of the cabinet. On the other hand when Bucks County Soapstone makes the template for your countertop we can measure the inside of your cabinet and make a sink that will fit, I am saying we can make the sink any size, using the whole interior of that cabinet. Look at the photo with our soapstone secondary sink, this sink is under-mounted just like any other sink.
