Hello
Should I have construction plastic in the wall in the bathroom behind the OSB board, or can I skip it since there will be a moisture barrier on the gyproc board?
I have underfloor heating milled into the chipboard in the bedroom and have purchased Pergo click flooring. The salesperson says I need construction plastic under the click flooring, could that be correct, especially as it's on the upper floor?
Thankful for advice!

You can skip the plastic in the bathroom walls just as you say. However, it doesn't hurt if you do add plastic, especially if the waterproofing layer is a membrane.
I don't understand what function plastic under the floor would have in a joist between floors.

Mmm, but why would there be more condensation from below than from above? The underfloor heating pipe itself does not emit condensation.
Edit: however, I have not done a doctorate in this subject, there might be a good explanation...

The reason for having plastic under the floor is that there are different temperatures on the top and underside of the floor. Without plastic, there will be different RH on the two sides, hence the plastic. However, I've personally gone 8 years without plastic and haven't had any problems. So plastic or not is a matter of preference.
