House code in Finland requires mechanical ventilation with vents in the bathroom. I only see brief condensation on my bathroom windows when I leave the sauna door open in the winter (approx. 100 celsius, 80%RH).
With good building codes, you won't have condensation issues.
- hkt 4y agoAlas, the UK has the twin problems of poor building codes and lots of old housing stock that nobody puts much thought into maintaining. In the latter case, people will take single skin brick buildings and apply "vapour control" materials outside the building, thus ensuring moisture is locked into the bricks. Then they wonder why they have damp, etc. Alas, we are a very silly country.

- hkt 4y agoSand and cement in my house's case. Rubbish insulation, utterly impermeable - combined that means the dew point (where water vapour condenses) is within the brick. The freezing point is too, and bricks are not exactly flexible when saturated with expanding and contracting substances. Some insulating panels are also dreadful, but on the whole a semi-competent installer will do the thing right. The problem is, some aren't even that good - we're talking a minimum bar of an NVQ level 2, and that's if people don't decide to just.. go self employed and do it without training. No regulation at all, and there can't really be any until it is a licensed occupation.
