Window directly at the shower, parapet height?

Hi,

does "by chance" any of you have an idea how high (above the shower tray floor) a parapet must be at minimum if the window is directly at the shower (Fe-bench approx. 12 cm)? And does the window have to be made of special glass (due to risk of falling through, uh, risk of falling [why does my keyboard suggest 'sturzbetrunken' (totally drunk on a fall)???])?

In my childhood we had to put extra bars in front of the shower window (outside) so that a possible faller would get stuck in the shards and not plummet 5m onto the asphalt...

If it matters: it’s about Hamburg, and an old building (but the regulations are the same, right?).

Thanks,

For floor-to-ceiling windows, there are two options for security. The "streben" you mentioned (French balcony) or the lower part of the window is fixed and laminated safety glass.

No, not floor-to-ceiling, rather "normal" window height. But since the shower is built on the floor, everything comes higher ...

Are there any measurements anywhere that are still allowed?

A drawing would explain a lot ;)
Do I understand this correctly: a window in the shower?
Why would the risk of falling be greater there than elsewhere?
