Good evening,

I would be interested in your experiences regarding the following matter:

Our house is being built by a developer. The construction description specifies that all non-load-bearing walls are to be made of 8 cm thick gypsum boards. This also applies in our case to the wall between the bathroom and the bedroom. The sanitary pipes for the shower and bathtub are installed inside the gypsum board wall. Since it is only 8 cm thick, there is not much wall left in these areas. Here are three photos of a house in the neighborhood; in our case, the pipes have not yet been installed.



From my point of view, I now have three options:
1. Have the installations carried out as they are and accept everything as is.
2. Lay the installations on the wall and have it clad with drywall. This is still possible at the moment. However, a reinforcement for the glass wall of the shower we plan would have to be considered.
3. Have the installations carried out as in option 1. After handover of the house, I could then build a drywall partition (possibly with insulation) myself in the bedroom. The loss of space would be acceptable and we wouldn’t have to make the developer unnecessarily richer. ;-) The painting work will be done by us anyway.

Now I would be interested to know:
A) What is the noise level in the bedroom with the execution as described in option 1? Will I feel like I’m standing in the shower with the bed?
B) Can you estimate by how much (in percent) the noise exposure would be reduced in the second or third version?
C) Are there any other alternatives? Although nothing can be changed about the gypsum board wall and its thickness.

Thanks in advance for your feedback.

Best regards
