Experts and BHG readers answer.
It seems to me that a quarry tile would be in keeping with the décor and the environment. It would be durable, though kind of hard to keep clean in my opinion. I may suggest you take a look at some of the new hardwood flooring. There are a lot of wider plank styles that may give you the architectural look you want but already come pre-finished with up to 7 coats of urethane. These can be very durable as well.
