Bathroom window: frosted glass or clear glass?

another question: with frosted glass, one side of the window glass is treated and thus rough. That can't be cleaned as easily as a normal smooth window, right? So frosted glass would be better (where both sides are smooth), right?

For us, both outside surfaces are smooth.

Maybe with triple-glazed windows the inner pane is frosted, so the outside is clear and thus smooth?

Quite possible. We have triple glazing.

That's how it was explained to us. However, we decided against it because we couldn't definitively judge the appearance from the outside and wanted to remain flexible.

On the ground floor next to the front door we have a small bathroom with a shower, or is the window completely frosted glass. On the upper floor the floor-to-ceiling window is divided into two parts: bottom frosted glass (fixed), top with a pleated blind ([Flügelfenster]).

We have the Satinato patterned glass in the bathroom, the guest bathroom, and the pantry, and we are very satisfied with it. The additional cost for four windows was a total of €460. In the picture, you can see the four windows on the north side of the house. They are the four windows positioned one above the other.
