If you make a running water device on the outer wall, then you need to set up a water circulation system, because if it is not a mountain villa, you basically need to recycle water. Then, it is best to make such wall suggestions on the outside of the building, that is, choose to make such a layout on the side of the building, or decorate the inner wall. In fact, the mobile wall can also be made indoors, which is an indoor decoration. We can make it ourselves or buy such a mobile wall directly to decorate it.
