Curve PEX around niche?

[TheGewp]

Are there any drawbacks to running a pex line from the mixer to the shower head like the picture below? What size pex should I use, 1/2 or 3/4? I am redoing the shower on this side of the wall and want to put a niche in where the current shower line runs. Thanks!

Not a problem. 1/2 is good, but you have to figure out what goes at the elbow. A drop-ear elbow screwed into some wood, that you would add, is the common way.

Thanks! Yeah planning to add a 2x4 and a drop ear for the shower arm. I would likely come straight across the top too and eliminate a bend.

I'm assuming you'll be changing out that old 3-handle tub/shower valve to meet current building codes of anti-scald tech?!

Yup! That bathroom is next, gotta keep it functional until this one is finished though.

This drop ear makes that installation a lot easier with backing.

I was actually looking at one of these, as I replumbed with PEX-A a few years ago. I don't mind sweating in an adapter to the one you suggest though if it will fit better and be more stable.

you could mount the 90 to the block and attach the PEX prior to mounting the block to the studs.. otherwise you have no access to the tabs.
