Bathroom floor above kitchen

[tullemannen]

Sitting and sketching on a future house and floor plan.
2-story house. How does the company view having a bathroom (WC, shower, bathtub) above the kitchen?
Do you have personal experience?
I'm thinking about the noise from the plumbing.
Is it possible to "build away" the noise in the intermediate floor? The floor will be built in wood.

There's probably not a big risk of it being full in the kitchen and bathroom at the same time?

It is probably not a big risk that it is crowded in the kitchen and bathroom at the same time?

Yes, unfortunately it can be. 3 children with friends, guests, etc...
I'm not really that sensitive. But if I have the chance to influence the new build, I want to do it.

Unfortunately, that can be the case. 3 kids with friends, guests, etc...
I'm not really that sensitive. But if I have the chance to influence during the new construction, I want to do it.

Insulate the sewer pipes and there shouldn't be any major issues. It usually makes noise as it flows down. That pipe should end up in some shaft that can be insulated quite heavily.

Insulate the drain pipes and there shouldn't be any major issues. It usually makes noise when it flows downward. That pipe should end up in some compartment which can be insulated quite effectively.

Depending on the thickness of the joists (which I don't know yet), I'm considering placing noggins under the drain pipes (not in contact with each other) and then putting several layers of plasterboard between the joists. That way, there could be 4-5 layers of plasterboard in total under the drain pipes (including the ceiling). I have seen that there are also "soundproof" drain pipes available for purchase. Together with mineral wool, it should be quite silent. But I don't want a lot of gurgling in the kitchen ceiling.

Soundproofed plastic drain pipes are usually not very quiet anyway. Rehau's raupiano plus with rubber suspension is a good start. But you must ensure that it is installed according to the instructions and does not contact the joists.

Since the plastic pipes are quite light, there will be a lot of splashing anyway, so you need to increase their weight with bitumen or something else heavy.

A suspended ceiling with three layers of gypsum should be enough.
