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 The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.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?

I don’t understand why there is so much discussion about the direction of the bathroom door opening. For us, when building our first house, it was never really a question.
What’s the disadvantage if it opens into the hallway? Aside from the obvious emergency services issue, there’s also the fact that if it opens inward in such a small space, you basically have to pull the door open right in front of your face or risk falling backward onto the toilet. Why would anyone want that?
This issue happens every time you use the bathroom, while the problem of the door swinging into another door in the hallway is usually just a rare coincidence.

hanghaus202313 Dec 2022 12:28I haven’t read everything yet. But 1 meter (3.3 feet) width should always be enough. With a 60 cm (24 inch) door, the issue with the washbasin— which is also available in narrow versions—relaxes. Is there no possibility to place the toilet under the stairs?
81 posts just about the guest toilet. 🙄
@T-i-m-m Is there a final decision yet?

I had expected at most 2-3 replies like "There is no standard, just make it as wide as you want," and then the thread would fade away 😳
The conclusion is that 1 meter (3.3 feet) is sufficient, and the general contractor agrees to build it that way.
However, there are still a few other factors to consider. Almost everything is interconnected in this kind of house planning. The plan is to make the guest toilet as narrow as possible. But there is a dependency on the staircase. It only works if we can position the stairs so that the attic has an exit point with enough headroom. At least one design did not allow for that. The building height depends on the required setback distance from the neighbor. However, there is still some room for adjustment upwards.
Long story short: If the stair position allows it, the guest toilet will be 1 meter (3.3 feet) wide. The door swing direction has not been decided yet.

hanghaus202313 Dec 2022 13:22I made the following changes.
The left wall of the WC was reduced from 17cm (7 inches) to 11cm (4.3 inches).
A smaller door (60cm / 24 inches) was installed to avoid conflicts with the main entrance door.
The door opens outwards.
A narrower washbasin.
A window in the WC.
The door to the living room was moved to allow the entrance area to be used as a cloakroom.
Your questions show that your floor plans are not yet fully functional. As others have already suggested, you should share them.
Preferably along with the completed questionnaire.

Seven years should have been more than enough to verify my suspicion about the thermal bridges – in any case, the original poster should not build as shown in the drawing (we have several threads here about party wall thermal bridges, although I no longer provide my extensive linking service for them). To be honest, I didn’t understand what you were getting at, so I didn’t comment on it 😀
I’ve never heard anything from my neighbors, if that’s what you meant by sound.
