How should water pipes be laid

There are no rigid rules like with electrical wiring regarding how water pipes must be laid. Therefore, one takes the opportunity to take photos during house construction in case they are needed for renovation and extension work. These would then also be passed on when selling the house. However, any horizontal method of laying the water supply lines in a shower would surprise me ;) That means: I would have expected vertical installation as well.

What did you want to do there with the drill?

As Sebastian already said, that is installed vertically, what is wrong with you? The fact that the cables are bent in the last 20cm is state of the art and saves unnecessary angles, which represent potential weak points

Not only that, the breakthrough in the ceiling must be kept as small as possible in order not to weaken the statics of the ceiling.

Normally, I can assume that pipes are laid vertically, at least that was always the case in older apartments, but that is exactly the problem with today's house construction: fast and cheap, cheap labor or those who don't want to chisel two grooves. Unfortunately, I couldn't take any pictures because I took over the house turnkey from the developer. The shower panel we wanted to install is from Hans Grohe, and the holes are just below the outlets.

Which shower panel is this?
