Battening an un even brick bathroom wall

[HannahVanston5]

I am currently trying to batten an extremely un even brick bathroom wall, before cement boarding on top, as this wall is where the shower is going to go.
The shower pipes plus the uneven bricks is creating a nightmare to create a level surface that comes out far enough to clear the pipes.
I have been trying to chisel into the 2x4’s I’m using as battens so they are plumb but it’s still coming up as not level and taking ages.
I have seen people using packers to create the level however if I do this the bottom of the batten won’t be making any contact with the wall.
Any ideas or help would be appreciated.

I use plastic packers, and if the gaps are big, plastic fascia boards cut down to make DIY packers, 90° to the battens. I concrete screw the batten to wall through all the packers.

I then get the foam gun out and back fill the gaps from the batten to wall. Once cured it's rock solid, you can then add more concrete screws (if needed) to hold it all to the wall.

Do one batten at each end of the wall, once you've got it plumb, you can run a string line from one to the other to get them spot on.

Good luck.

OP,
Why not post pics of the wall?
