Kitchen countertops are Chinese granite slabs, which come in any size you like so long as it's 8' by 25½"; your choice of front side bullnose or three sides bullnosed. I borrowed a little wet/dry circular saw w/diamond blade from a tile setter friend to cut the slabs, and hired a helper for a half day to do the job—those slabs are heavy!. The countertops sit on ¾" plywood underlayment, and are bedded in silicone, a continuous bead along the edges and blobs spaced about 3" in the field. On the sink side, the 12' length is made of two 6' sections epoxied together; the sink cutout is done after the silicon and epoxy have set up, since the skinny bits would be very fragile otherwise and there's a good chance of breaking them.
