I am constructing a new kitchen and some people are suggesting, first make partitions using marble and then you may fix up the fittings, whereas others are saying that, place the wooden box directly, and then you may use the fittings easily. Few are also suggesting to put a concrete slab and then below that fix the wooden boxes. In first two cases, granite will be placed directly on the top. I am planning to use, Waterproof board with 1 mm thick sunmica, Please advise what to follow for durability and long usage. In any case, we are putting tiles at the bottom and back of the wall to protect it from termites.
