Hello house building forum,
we are currently planning a semi-detached house. The building plot is very small, and the footprint is accordingly limited. To achieve a reasonably usable living area, we want to keep non-living spaces small and allocate the saved space to the living rooms.
On the ground floor, we are planning a guest toilet without a shower—that is, only a toilet and a washbasin. Recently, I have been carrying a laser measuring device when visiting friends and have measured several guest toilets. Conclusion: 1 meter (3.3 feet) in width and 2 meters (6.6 feet) in length are more than sufficient. In our case, the door would be on the short wall, the toilet opposite the door, and the washbasin on the long wall.
We are currently looking for a builder and have roughly presented our plans. One potential builder mentioned that according to the DIN standard, a guest toilet must be at least 1.24 meters (4 feet) wide.
My online research so far hasn’t been enough to find the relevant regulation or DIN. The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.
Is anyone familiar with this requirement? Is it not allowed to plan a 1 meter (3.3 feet) wide guest toilet in a new build?

With multiple people, someone can always randomly enter the house while someone else is coming out of the toilet. And during warmer seasons, the front door might be left open for a longer time. This means you always have to be very careful when opening both doors.
I wouldn't do it that way. Actually, despite having a very small guest toilet, we have the door opening inward.

We thought about the door arrangement for a long time and ultimately decided on it despite the possible clash, because it allowed us to fit a shower into the guest bathroom, and made the toilet more practical and comfortable to use. In over 10 years, nothing ever happened, not even with children. In any case, regardless of the door situation, our front door is never left wide open for a long time.
@Yaso2.0 if it was actually constructed exactly as shown in post #42 – that is, with insulation and cladding carried seamlessly over the separating joint – then your house joint within the essentially "party wall" would be flawed, and there would still be effective sound bridges (?)
