Thank you for all your comments. We have been looking at the black granite composite made by Franke but is triple the price of Blanco. Was concerned the black composite would scratch etc. will probably go two stainless steel, because as previous poster mentioned the blacks are never the same. Sure I will be back for more help or advise.

How about butcher block instead? IKEA and the big box stores sell it for countertops, the price is decent, and you won't have as many issues with buckling, water damage, or what to do with the edge as you would with the ply. If the edges of the ply get wet, or if any seam around a sink gets wet, the plywood will "blow" and you will have to replace it all, anyway.

This is a kitchen going into a dog kennel building so I'm not too worried about resale. My dogs are raw fed and so I spend quite a bit of time prepping food, washing bowls, etc. I'm only 5'6" but I've been doing these tasks in our house... in our current kitchen which has counters at 35 1/2"... and my back is constantly killing me after I get done. I've purchased a long stainless steel counter top for the kennel (with built in sinks) but plan on the cabinets underneath being custom built. Just can't figure out what height. I was wondering... if I'm sitting at a table (which is comfortable for me to work at for hours on end) and I measure where the table top "hits" on my body and then stand and measure the distance to the floor, it's about 41". I'm wondering if that is an indication as to where my counters in the kennel should be! Seems awfully high! I may need to take the counter top I've bought and put it on some saw horses and varying heights and work on it to see what is best before I make the call!
