Can I put hot cold pipes for sink in exterior wall

[lost_diyer]

I’m hoping to move my sink hot cold pipes into an exterior wall. They’re currently coming up through the floor but we’d like a floating vanity so the pipes need to be routed into the wall.

Is putting these pipes through an exterior wall a bad idea? I’m using plastic pipes.

Do you mean you’re putting them in the cavity?
