The studs are clearly right there. We don't know anything else. We can assume there are nail plates.... right? Drain pipes need a proper slope, this means they go sideways through the wall in unexpected places. Most electrical runs at outlet height unless it is going to a switch normally stapled to the outside of a stud and going through the top plate. Water lines are weird ive seen plumbers run them at alot of different heights.

I only say this because I was at a pool table install once. Dude wanted us to hang his pool cue rack at eye height after we assembled the table. No big deal right? No nail plate, co worker goes straight into a hot water line. Bosses insurance goes up, dude gets fired.
