This house had marine ply under laminate (3/4") that held up well, the cabinets weren't backed & let every critter imaginable in, so we got rid of the cabinets, but are still using just the counter top while we think of what to have next... but think the marine ply is the way to go to support the finish counter surface.. (granite tiles usually have the 1/2 tilebacker like hardibacker)
