If you are thinking to do Corian yourself, when looking for a 2'x2' piece of Corian a few years back for my boat, I found that distribution is tightly restricted by the manufacturer to authorized dealers, who generally only supply to the trade. As an individual consumer I could not find a source. Eventually, I was able to get a lead from a local kitchen remodel showroom/contracter about their Corian supplier/fabricator. When I showed up at their door, then they were happy to let me take a look at their remnant area (which was over-flowing). When I did buy I was amazed at how subtle differences in color/tone/pattern affected the appearance once in the boat. Eventually, I unscrewed a piece of fiberglass gelcoat from the boat's interior and brought it with me for color matching. If you find a piece you like, be sure that the shop will let you exchange if the color doesn't work.
