Steamy bathroom

[John Brown]

When the steam from the shower hits the cold air from an open window... it instantly turns the water vapor into water. It's why you end up with soaking walls if you leave the window open... a fast extractor fan pulls this moisture out and expels it outside.

In a normal setting without the steam/shower you would be correct. Heating and a trickle of circulating air air from outside will produce low humidity and dry walls... in a bathroom... not at all.

Ah! Thanks for the explanation!

Isn't it a very simple no expense thing to test? "Try having the window closed and tell me if it's better or worse".

If that's directed at me, then it'd be impossible to test, as I don't have a window in my bathroom. I wish I did, but it has no outside wall.

Well I went for a look at the property yesterday and the bathroom was absolutely running with condensation, still no heating on.

The extractor was working but probably not as well as it should so I've organised for a more powerful one to be fitted.

Hopefully heating, more extraction and correct ventilation will sort things out
