We are in the process of designing our kitchen. We ran into a snag with the island. The island is currently 136 inches long and we would like to finish it with a granite or quartz counter top. We informed ourselves with several stone manufacturers that the average standard size is 120 inches. What do we do? Do we keep the island at 136 inches and live with a joint across the counter top? Do we modify the island to accommodate the 120 inch slab? Or, keep the original 136 inches and combine another material with the stone?
