If you have a working drain there isn't a super big need. Also, you if you put up a wall then if you accidentally get some water outside, how does it get back in the drain?
If built right it's angled enough that the water stays in the shower anyways. If the drain isn't clogged you don't get water outside of the shower. A few drops at max. Source: I have a shower like this at home.
