My husband installed a jaccuzie tub and built the surround for the tub which sits on a built platform. Now we need to tile the surround. The surround is built with pressure treateat lumber. Can I use any type of tile. I would love to use a marblized look tile. Do I need to use a certain thickness and size tile? Which tile type is the best to use for the surround. What do I need to have before starting this project?
