I am moving into an old home and the bathroom has a free-standing tub. How can I mount a shower head? - free mount

Currently, there is a "shower head on a hose, I'm not sure what the correct term for it. It reminds me to pass through the nozzle and / or tube wells to spray that can be on dishes.

I think in a vertical or mount that support creates the wall may be the way forward, but I have no idea where to buy something. Any tips?
