Hi there. In the middle of a new build. The builder asked me to look over the rough plumbing and I have no idea what I’m looking at to be honest.

One thing that caught my eye though is the body sprays in the shower. This looks different than the pressure balance loops I see online. Those look more like a ladder that a big circle.

I want this to be right - is the way it’s done right? Should I ask for it to be done differently? Want to be reasonable but I honestly am not in my element here.

Any advice is appreciated.
