I got my tiles from Negros Builders and liked the quality, selection and cost. Definitely use tile adhesive and not cement. If your floor is low or uneven I would recommend a mud bed first to save on the adhesive. Shawn
What he means is to use a layer of concrete to level the unevenness of the floor and then use a thin layer of tile adhesive to adhere the tiles to the concrete. I agree with this recommendation. "Mud" is a layman's term for concrete because it has the consistency of mud when poured.
