I've seen several coaches that have had hardwood flooring installed and so far have been less than impressed with the finished product. Not that the jobs weren't well done...they were. I's the visual effect that doesn't look as good as nice tile work. The hardwood is just too "linear" with all the strips running fore and aft and no geometric pattern to add interest. Also most are too dark for such a small area.
I think the hardwood could be done well and have a "WOW" factor but all I've see so far are boring and needs more imagination.
