I would like to do a Talavera Tile as part of our kitchen remodel on one wall which will include the area behind the stove. I have never had tile in a kitchen before and I am wondering if there is anything special that has to be done to it - especially the grout - to keep it looking nice and clean. Does it have to be sealed? I am a real novice with tile but I love the colors and patterns of the Talavera Tile. I would also like to put it on the area between the tiers of the island. What are your suggestions? Are there any good places online to buy the tiles? Any to avoid? Thanks for any of your suggestions or input!
