It's true that you shouldn't attach wood directly to concrete. It can absorb moisture from the slab. For the same reason, you should also leave both plywood/OSB and drywall about 10 mm from the floor when you attach it.
Oh right. Then there are U-profiles with ready-made underlay attached on the underside. Buy those so you can skip the sill paper. Sill paper is significantly more expensive.

Sufficient with a plastic sheet under the joist against concrete, age-resistant. 45 cc is more than enough since you use 15 mm plywood in the bathroom. I've never experienced anyone using 30 cc for joisting; that measurement is usually used in the floor structure in bathrooms.
Fun to be able to help

If you attach a wall directly to the slab, it becomes really stable. Use a bolt gun or drill and secure with proper nail plugs. Be careful not to use ones that are too long if you don't know what's underneath and at what height.

You can certainly choose a wooden stud for the wall as well if you want. But as mentioned, you must then have, for example, Syllpapp underneath. Also, you have to be more precise when cutting the studs so they are straight and fit well in length. With metal tracks, it doesn't matter if the stud is a few cm shorter or a bit crooked when cut. So you can easily rough cut with a circular saw, instead of having to measure precisely and cut completely straight. If you have access to a miter saw, it is certainly even faster and does come out straight. But the measurement doesn't have to be exact. It's not a load-bearing wall you are building. Additionally, a steel track is straight and doesn't move. A wooden stud that comes into the warmth from outside can easily bend or twist.
Aha! Then I have also learned something new Never heard "granab-reglar" before.
