You can install our Slate Flex Tiles - Designer Series over marble or any other hard flat surface. The transition we offer for this product is a ramp, so it may not serve the purpose that one would be looking for. We do offer a wide range of transitions on our trims and molding page that would be more appropriate. You can install out tiles in any room in your home, so these tiles would work great as flooring in a galley kitchen. These tiles feature a unique hidden interlocking design, making the process of finishing the floor quite simple. Essentially, all you would need to do is just install the tile as needed and cut to fit. The finishing sides will have a slight beveled edge giving your floor a finished look.
