I've just started remodeling a tiled shower. According to a video I saw on line, once the tiles have been removed the screws holding the backer board to the studs should be visible and can be removed, thus allowing the backer board to be removed.
I've removed the tiles from one section, but there is no sign of any screws. I was able to get a pry bar under an edge and pry it off, revealing nails whose heads were tight up against the mesh and driven into the wood, but with no hole on the surface and no evidence of a hole having been filled after the nails were driven in..
Further, either the backer board was somehow wrapped around an outside corner -- and with good clean straight edges -- or someone had managed to cut a clean straight edge in the cement part, leaving the mesh to be wrapped around the corner and nailed under the backer board on the adjacent surface. I don't know which, as I haven't yet removed the backer board from that second surface.
