Roller shutters in the guest bathroom, yes or no?

the question is whether we even need a roller blind in our bathrooms or not

Is that a shower bathroom? Is the window small? Is the parapet set higher? Is the window directly opposite the shower or where you can be seen? Those would all be points upon which one would decide. If it’s a 50 x 50 window with a parapet of 150, then you probably don’t need roller shutters... if you have a floor-to-ceiling window opposite the shower, then privacy protection would be advantageous...

For example, we have nothing in front, no frosted glass either, the window faces the street – no one has ever complained ;)

why is a roller blind not burglary protection?

Not protection, but a deterrent. It also depends on whether the window is visually shielded by a hedge. If you have a townhouse front garden on a street with the mentioned window, then a criminal would certainly not break in there, but rather on the terrace/garden side without street frontage.

I would probably also let the appearance decide: if the other windows also have roller shutters... however, it may be that the window stands out from the frame anyway, so a roller shutter wouldn’t work due to uniformity.

Is there actually a thread from you where the whole house is presented?

I also think it looks totally lame when individual windows don’t have shutters. In my opinion, saving money in the wrong place. But that’s just my opinion.

I think it looks lame when on nice days all the shutters go down around 8 to 9 pm, creating a cage and total rejection towards the outside. The house opposite my apartment has such a program and in the evening you look at the house and think, what a cage ;) ;) ;).

and create a cage and a total rejection to the outside.

Most people create the cage very well even without roller shutters. Using hedges, fences, etc. Behind such a "nice" 2m privet, the neighbor sees nothing 365 days a year. I don't necessarily find that better, rather worse.

Curtains, pleated blinds, Venetian blinds have the same purpose by the way. The cage is there anyway.

The thing with lowering them in the evening. We are no longer in the previous century, even though most people still install and set it up according to grandpa’s scheme. Of course, in modern houses the roller shutters only go down when they have to (when they have to is, of course, different every day) and not punctually and daily at time x/y.

I don’t understand this dispute that is currently running through various threads. Privacy screen yes/no, roller shutters yes/no. Everyone should do as they wish. I also don’t stand there and say that I can’t understand how someone wouldn’t want privacy or wouldn’t close up at 9 p.m. Why? Because a) it’s none of my business what others want and b) I honestly don’t care. My quality of life doesn’t increase because my neighbors fully open their property or because I can see what they’re doing in the living room until 10 p.m. Conversely, it doesn’t decrease either if I could. So why should it concern me? I don’t understand this discussion.

Electric aluminum shutters offer more than just privacy. In summer, they really keep the heat out very well, and in winter, they insulate very well due to the filling material. Our shutters cannot be easily pushed up from the outside, and the aluminum armor cannot be cut. Therefore, they are not completely ineffective in terms of burglar protection.

and the aluminum armor cannot be cut either. Therefore, they are not completely ineffective in terms of burglary protection.

Did you install something special there? You don't even have to cut or push up the shutters. Without additional protection, they can be pushed out of the guide rails in seconds and then lie on the lawn, and the wider the window, the easier it is.
