I would use wood flooring and would go somewhat lighter than your island (but not into golds or reds). A stain such as provential or special walnut.

For a huge room like that, I would go with the Tile, Actually I would use a Travertine or real stone 16" x 16" on a diagonal. Here is a job I did in Tri Cities where we actually did a floor break following the line of the island mixing wood and stone. What are you using in the sunroom?

Here is another job we did a huge travertine on a diagonal.

Thanks what color is this tile and where did u purchase

Oh my, on the Bar? That project was completed 8+ years ago. I could actually
still find out however. I find that on these major home's you end up spending so much time with the Client that in the end your friends for life. I will call and find out. Stand by.
