... and then brushing teeth with four people in front of the door - oh nooo....
So we currently have a similar layout and everyone can brush their teeth. In winter/autumn with and spring/summer without lights. But it is also intended as an alternative for the builders, since they a) gain a lot of space for storage (cabinets) or luxury (sauna) b) the toilet is hidden and well ventilated c) when entering the bathroom the sinks are immediately at hand (washing hands is a frequent concern, right?) and you see a large mirror surface, which I personally find more pleasant than a shower cabin d) daylight comes anyway only through the two side windows. Whether it shines all the way to the sink by the door, I would leave open in all designs. ;-)
