Fixing bath tap shower mixer to wall

[Matt0029]

If have the below shower/bath tap mixer to fit. The finish wall won't be tiles but plastic sheeting. That isn't too strong. So I want a way of fixing the shower to the wall before it's sheeted. Do I use the offset connectors supplied and a back plate elbow or buy shower mounting kit? It's on to a solid wall, well it's a thermal block wall.

You could use backplates and nipple or maybe this ?

Thanks shaun do they do the nipple as a straight? I have never understood the advantage of it being offset.

Yes it’s called a running nipple if straight fully threaded or barrel nipple if you don’t want it fully threaded

Stick two 15mm pipes out that are properly secured in the wall then use a fast fix kit? Usually do bar showers like this with plastic paneling and don't have any issues, can't see a bath/shower mixer being much different?

That's what I wanted to do but the shower bath mixer is heavy. I'd worry that it may pierce the plastic. That is hollow on the inside.
