To build a sustainable and crack resistant bathwall type one should consider PVC tiles. On another spectrum one may consider wood and metal with caution.
The best solution for bathroom tiles for mobiles structure is PVC tiles. These are easy to install, do not crack and have the look and feel of real tiles.
You can also use wood finish in bathrooms. When using wood finish a sufficient ventilation (fan exhaust) is required to prevent moisture build up and mold. Before applying wood finish we recommend applying a layer of tar paper then the natural wood. The natural wood needs to be coated with some type of sealant/urthene on all sides before installing.
Metal Panels can be considered and are least expensive and easy to install on bathroom & kitchen walls.
There are also other options such as using a water-resistant paint on high impact resistant gypsum board.
