One of the things that really help us decide on that question is “How much traffic is in your home?” Sometimes a wood floor can really give a really good continuity between rooms and a nice warm feel to the Kitchen but when there are younger kids or your home is “the place to hang” I usually recommend something more durable like tile. There is a lot of great wood looking tiles today and if the installer does a “random” pattern you can really get the best of both worlds. If you decide to go with an unfinished wood floor I always recommend a few things: 1. Pre-finishing under the cabinets 2. Adding drainage holes behind the Dishwasher and any water source (Ref. Icemaker, Sink…) 3. Adding inexpensive leak detection sensors ($15 @ Home Depot). And last you can always use a Hand-scrapped floor to hide future scuffs.
