Plumbing – How to route the shower plumbing back into the wall

plumbingshower

I have purchased an exposed shower valve similar to this for a ground-floor shower room in my home.

I would like this connected to a ceiling mounted rainfall shower like this.

So I need to be able to route the shower valve outlet back into the wall that the valve is fixed to (and then the pipe will go up behind the wall, into the first-floor floor cavity and then back down through the ground-floor ceiling.

But I am not sure what connector to use to attach to the shower valve outlet to route it back through the wall. Any advice?

I have found this but I'm not sure if this is what I need.

Otherwise you would need a control intended for all the plumbing to be inside the wall like this:

There are a number of accessory finishes for the handle and trim.
