What type of union for wall mounted shower

[nick9one1]

I've just ripped out my bathroom and set to install one of these over the bath.

Its 3 way, so I need to fit a wall mounted bath spout, fixed shower head and handset.

The wall I'm fitting it on is only 2 1/2 inches thick, so I will be building a false wall to hide it all.

My question is what fittings should I be using to allow the shower arm, tap etc to screw into.

this?

Yes that’s a good choice

Depends on the shower arm I guess. Cant go wrong with a wall plate elbow as you are able to screw it up really securely, if the shower arm has a 1/2" threaded end. If you can though use a soldered fitting if it is to be hidden in a wall.

Thanks. Picked up 3 Yorkshire wall plate elbows with the solder ring instead of compression.
