We are in the process of designing an outdoor kitchen. Anyone out there have an outdoor wood fired pizza oven? Can you share your recommendations on what dimensions/materials or design specfics we should consider/recommend to our contractor? We're probably looking for a small one 54x52 but we definitely want it built into the grill/bar island that will be constructed. Also if you've owned an outdoor wood fired pizza oven - can you share feedback on how often you use it and how's the upkeep?
