ᐅ Wall thickness for children’s bedroom / bathroom

Good evening,

has anyone had experience with how wall thickness affects sound transmission?

Currently, the shower is planned directly adjacent to the wall of the children's room. In the children's room, a wardrobe is planned along the wall facing the bathroom (a desk is drawn here for now; the children's room window will be moved so the wardrobe fits against the wall). At the moment, a 17.5cm (7 inch) thick masonry wall is planned. If a 10cm (4 inch) masonry wall would be sufficient without making the children's room too noisy, we could reallocate those 7.5cm (3 inch) to increase the shower size. Any experiences?

Recommended course of action for me?

Minimum 17.5 cm (7 inches) wall or lightweight construction

We don’t hear any noise coming from the bathroom, whether it’s the shower, hairdryer, or radio. Therefore, we are satisfied with the wall thickness in that area.

By the way: The noise level of teenagers cannot be compared to the sound of the shower or other noises. Teenagers are always louder!

I don’t mind the children's noise in the bathroom. Here, the concern is the noise from the shower that might carry into the children’s room and potentially wake the child.

Phew... do you already have children?
A baby won’t be woken up by anything at all... and then comes the phase where the baby needs to get used to noise in order to cope with sounds.
And if everything is done wrong, the toddler can’t sleep because they suddenly hear a pin drop

You can, of course, follow Sebastian Lexmaul’s approach and focus on a) the wall thickness, b) the quality of the door, and c) then the wall material.
Maybe also leave out the cupboard, the sounding body... that was a joke

Personally, I would focus on good doors; that should be done anyway... Bathrooms are usually double-layered on stud walls, and the other options are also walls that have their valid purpose.

Now you’re getting strange ... Yvonne’s answer (personal experience) carries as much or as little weight as yours (personal experience), a few replies earlier

Nothing strange – if I don’t know how loud a washing machine is, it’s hard to use it as an example. My parents’ new Miele is incredibly quiet; I never thought these machines could be that silent.

So, I wasn’t questioning the experience itself in terms of reliability, but rather the statement, “I don’t know the decibel level of our washing machine, but I’ll just use it as an example to refute Sebastian’s point.”

Besides, at no point in the order Yvonne claims did I ever guess anything...

I am not disproving anything, and certainly not you, lexmaul; I am simply sharing an experience, just like you.
