I think that at least in East Asia and Northen Europe like Scandinavia it's normally naked, just towel to sit on and cover if you want and also quiet in the sauna as a rule, not always no talking at all but kinda like in libraries. Showers naked to get real clean, no bath or sauna allowed before naked shower and cleaning off and normal to walk naked in and from changing rooms to showers and saunas and depending on country and place it might be divided men and womens the baths too and then even naked in the baths. And gay saunas, anywhere, well that's another thing...
The way fadel and bison call their mom is not normal because they call her "Khun Mae" mae is mother and 'Khun' is used in a formal way.
