Walk-in shower, splashing water, do I need a door?

Hello everyone,

I need your advice :). We are currently planning the bathroom in a new build. I have attached the bathroom layout.
The shower area is L-shaped, dimensions 160x100cm. The "open wall" is 80cm long, and the entrance area to the shower is also 80cm.

Question: Is the 80cm wall length sufficient to prevent splashing water from escaping the shower area? Or should we rather use a door?

According to a consultant at the sanitary trade, that should be enough. On the internet, I read about a minimum length of 120-140cm.

PS: The supply shaft is certainly located in the thick wall between the WC and the shower.

No, that is definitely not enough. I have 120cm of wall and 60cm passage and it just barely doesn’t splash outside. And I don’t have a rain shower or anything like that. At least 100cm would be necessary and then only with a bath mat. But that would probably work, I think.

I almost thought so, then a glass door after all.

Do you also have an L-shaped shower?

You can try it out first. It works for us. However, I had to install a splash guard due to non-compliant slope, maybe that will help too.

L-shaped shower? No, I have a rectangular shower as shown here measuring 90x180. I find the 80cm a bit narrow and would widen it to 90 if possible. My shower control is "in front" inside the shower. I chose the length so that nothing sticks out and I don't have a door that I have to maintain. :D

If I were you, I wouldn't put the toilet in the back corner either. You use the toilet most often, maybe sometimes at night half-asleep. ;)
