Who makes custom sized BB & granite slabs?

You can check a local Stone and marble shop in your area and any millwork shop also in your area for the butcher block.

Just a 2 ft square slab of 3/4" granite, with plain corners, cost me about $200 each from a local stone shop. Shipping costs, if not local, can be prohibitive. There's a custom door place up here where some of the guys do projects in their own time.

Thanks all. I suppose trying to have something cut locally makes most sense...

You might be able to find something at Grizzly Industrial.
