Yes! Many of our customers choose to tile their brick Authentic Pizza Ovens after purchasing to give them a more "unique" design or to make them more cohesive with their entertaining area.
You can use any type of tile and choose to decorate however you'd like as long as you are using HIGH HEAT RESISTANT materials to do so. The mortar that you attach the tiles with needs to be high heat resistant to withstand the heat dispersed through the dome of the oven. Tiling your oven DOES NOT make it weather resistant and you will still need to cover your oven after you tile it to make sure you do not void any type of warranties.
