Two white metal frames for sanitary installation with pipes, hoses, and cables in a construction environment.

Base structure with open drain pipes, PVC pipes, black hoses, and metal frame.

Good morning.
We are currently building a prefab house with Allkauf Haus and have the Freetime package.
On Monday, the rough-in plumbing was installed and completed yesterday afternoon.
Unfortunately, all the pipes were laid exactly where a drywall partition for the shower needs to be. I wasn’t allowed to oversee this earlier because the company did not want me to. Someone mentioned that the pipes were incorrectly installed.
Their comment was:
I would also criticize the installation of the wastewater pipe. The 87-degree bends on the floor for the washbasins are completely wrong. This is not standard practice. The reducer for the shower is also installed the wrong way around. Was this done by a professional company? If so, that’s disappointing!

Can anyone confirm these statements? If so, I can address this this afternoon!

Best regards,
Sven

What does the room below look like? You could install the pipes on the ceiling there and then create a 50mm (2 inch) branch at the wall. The 50mm (2 inch) pipe fits inside your drywall partition.

The utility room is located on the ground floor, but the ceiling space is almost fully occupied due to the ventilation system. The pipes could still be easily extended further to the left, couldn’t they?

It depends on your shower and floor construction whether they fit underneath. With a level-access shower, it could be difficult.

pipes and I have no space for them. The pipes are located exactly at the 1-meter (3.3 feet) boundary, which is also the width of our WEDI panel.
If I move the drywall further to the left next to the pipes, I only have 80cm (31.5 inches) left, which is clearly too little!

Then the only option is partial demolition and repositioning of the installation frames by exactly the distance you are missing.

As mentioned before, you also need space to securely fasten the waterproofing frames...

Then everything has to be shifted to the right… You have enough space on the right anyway.

I agree with that.
I told them that from the start… but they thought the wall would fit there without any problems.

To be honest, I still don’t quite understand how the installation frames are supposed to be properly secured. Will the drywall partition reach all the way to the ceiling?
