ᐅ Planning a Guest Bathroom in a New Build – What Is the Minimum Size? (Building Standards?)

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 The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.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

Maybe this helps, maybe not. Technical equipment can sometimes be relocated to an external technical room built on the boundary outside the thermal envelope (in our region of NRW this was possible if there is no gas, oil, or pellet heating). This does incur additional costs but provides more free space to use the few remaining square meters.

There are things that are nice to have, and things that just are the way they are if not realized. Yes, a door opening outward shouldn’t be a problem, but for now, it’s best to wait for the facts regarding the site plan and orientation. Who knows, maybe a side entrance would be more suitable? That could again change the dimensions for that tricky guest bathroom...kbt09 schrieb:
That may be fine if you have no other choice. In my first tiny apartment, I only had a 75 x 75cm (30 x 30 inch) table, but that’s not really a dream for a house of your own.Well, 32 square meters (approximately 344 square feet) for three people is hardly a choice anyone makes. I’d also go for a small fold-out dining table. It’s possible that the family ends up eating together on the sofa, and hey: when there are parties, in Hamburg you can easily have them at Andro or Wai in the private room. Other countries set an example here. They always meet in public dining areas. That way, your own home stays private and compact. So, let’s wait for the site plan and so on.M

Sorry, I haven’t read everything, so I’m not sure if the topic is settled, but here is the guest toilet as shown in the floor plan from our previous semi-detached house. The size was fully adequate. Did you really go ahead and build it with the doors like that? Didn’t it cause any problems in everyday use?

The technical equipment can sometimes (at least here in NRW, it was possible if there is no gas, oil, or pellet heating) be moved to an external utility room built on the property boundary outside the thermal envelope. It does cost extra, but it gives more freedom to use the few remaining square meters. We had also considered a technical basement. However, it was beyond our budget. And given the house dimensions compared to the price, it wasn’t much cheaper than a full basement. Inflation and the global situation have unfortunately made the project considerably more expensive than originally expected.
