When installing tile on the wall around a Jacuzzi tub will sheetrock hold up as a backer for the tile. The tub will be approx 6" away from the wall all the way around and there is no shower. The wall should get no more water than a kitchen back splash. If I need to use cement backer board what is the best way to transition from the cement board to the sheetrock. The tiled portion will be less than 2' high around the tub. Robert
