Do you know how they seal the joints on the cement or hardie board ? I see videos for tile showers and they tape the joints with something same as you would do drywall , some time it is red color . The 2 big home improvement places have all the tile and cement boards and grout but dont have a clue what to use to tape and seal the joints .I've seen thin plywood or hardboard used behind fiberglass tub/showers with integral walls. I'd be nervous about using it behind a tub with tiled walls above. If there were any leaks the plywood or hardboard would disintegrate pretty fast. I'd feel better using cement or Hardie backer board.
