ᐅ Door opening inward or outward? What is the standard?

I would also have the door open inward, just as it is shown there.

I find outward opening impractical. To address the argument in favor of an outward-opening door: think about how often you have visitors who say goodbye, and someone needs to quickly use the restroom. This regularly causes “jamming” issues. I’ve experienced this thousands of times during childhood visits from relatives at my parents’ house, which was quite similar, except the door opened outward.

The safety/rescue argument isn’t fundamentally wrong but, in my opinion, it is much less common (hopefully never). And if someone does collapse and emergency services need to get in, they will manage to get inside anyway—it’s usually not a high-security door.

The only consideration for me would be if the door were to be implemented as a flush-mounted design.

I find a sliding door for a “public” restroom somewhat suboptimal due to sound insulation and locking issues. There may be solutions, but aren’t they comparatively expensive?

Inside - we have similar dimensions. No problem

In our old apartment, there was only a small hook. A strong tug and it would have been ripped off the door. In terms of emergency escape, this shouldn’t really have been an issue. We didn’t have significant problems with sound transmission. On one hand, we had a good toilet that didn’t make much splashing noise, and we filled the gap between the door and the wall with foam seal strips, which I believe are also designed for windows or similar. These strips have simple adhesive tape on the back. You can hear much more through our current solid wood door than we could through the sliding door back then.

Just sharing this from our experience in case anyone is interested.

When I say this is for safety reasons to the outside, I don’t want to cause panic, but my acquaintance’s neighbor supposedly died because the paramedics couldn’t get through the door in time. Someone had to enter through the first-floor window (about 1.5 hours delay). Now, depending on how good the window is, whether it’s on the ground floor or first floor, and how heavy the person behind the door is, this can be somewhat mitigated, but ultimately it remains a risk.
Will it happen to us? Theoretically, you can win the lottery once, or someone can play their whole life and never win. That’s probability. Here, what matters is how severe the situation is and your personal interest.
I was told (in the OR) that it could happen to one in 10,000, and my son was that one in 10,000.
I say no risk ever again if it can be avoided, but everyone has to decide for themselves.

Sorry, that would mean every door would have to open outwards. You can also lose consciousness in another locked room.

Nowadays, bathroom doors are fitted with an internal latch, not a key lock. The door can be easily opened from the outside using a coin, such as a penny, euro, or something similar.

This is not about the lock itself, but about the door. You can get a lock (usually, people even have several doors in the house keyed alike, as there aren’t that many different key types for standard interior doors).

In a sufficiently large room, it’s not a major problem if someone is unconscious inside – you open the door and go in. If the person is lying directly behind the door, you need to push a bit harder to move the door and get past them. However, in a very small room, the door won’t open but will only press against the person, trapping them. Bad luck. The risk of losing consciousness is likely higher in bathrooms because most people go there first when they start feeling unwell.
