Oh I have to chime in on loads of things now.
Windows used to open out here in Sweden too. Then they made it standard to have them open in so people wouldn’t fall out and die when washing them. Now I never wash them anyway because I have to clear everything off the windowsill and clear a metre into the room to do it. 
And I can never just open a window quickly. I love windows that open out.
If I had only one sink I’d probably use a bowl too, very sensible. Swedish standard used to be two fairly big sinks. Sadly in these days of freedom and choice and liberation from big brother standardisation they are disappearing. Stupidity I say. Two sinks is the civilised option!
Schools start at 8.15-8.30 normally. A normal bedtime is 20.00 I’d say. Families eat together, I think there’s been a shift so people eat at say 18.30, when I was little people ate at 17.00. Parents in Sweden might take turns in starting work very early so they can finish earlier and vice versa.
Since we’re veering into the more controversial differences, I have to tell you that Swedes are convinced that British homes are poorly built and of a poor standard. You cannot sway them on this - they will admit exceptions but that’s it. If you asked a swede they would say that’s why you don’t have plugs in bathrooms. (They conveniently forget that it wasn’t long ago that building regs here didn’t allow them either haha)
I’ve read interior design articles from the UK with tips like “to spruce up your bathroom, cut a nice linoleum to size and put it over the flooring” - Swedes think this is the maddest thing. All the dirt and wet being able to get in between the old floor and this new loose bit of lino. I can quite like the UK (and Irish for that matter) easier approach to renovations. In Sweden it’s very much do it properly and expensively.
