@coolboymew It's not complicated to have such a shower, you just need a bunch of those little showerheads and either some copper or easymode PEX. Showers are pretty simple, though to make a waterproof tiled shower like that one is a bit more work to get perfect, especially on your first attempt. Still not that hard.
Assuming you are a homeowner, you could convert pretty much any shower into this for no more than $1000, and depending on the solution you choose, possibly half that.
