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 The DIN 18022 on bathroom planning appears to have been withdrawn without replacement.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

A smaller door (60cm (24 inches)) so it does not interfere with the main entrance door.

To be honest, I didn’t understand what you were getting at, so I didn’t write anything about it 😀The plan shows a continuous wall section extending over the partition wall.The floor plans were presented in post #25. Other drawings are not yet available. However, discussions with potential general contractors are ongoing, and more detailed plans based on our designs will follow shortly. Some points from the questionnaire are no longer relevant to this project. Nevertheless, I will address a few of the questions:
Development Plan / Restrictions
Section 34 of the Building Code
House dimensions per semi-detached unit: 8.50 x 7.61 m (28 x 25 feet)
Maximum height approximately 8.68 m (28.5 feet)
2 full floors
1 attic space
No basement
Gable roof with about 33° pitch
Client Requirements
2 adults, 1 child
2 workstations (1 full-time home office, 1 workstation for a few hours per week)
Occasional overnight guests approximately every 3-5 months for a maximum of 7 days
Open living/dining/kitchen area
No kitchen island
Closed staircase/hallway
Small guest toilet (by now, some of you might have noticed that)
House Design
Planner:
- Construction company
- Ourselves
What do we particularly like? Why?
The small building plot does not leave many options. Under the circumstances, we consider our plans quite good. The attic will serve as a study and guest room. Without the attic, the project would be
What don’t we like? Why?
Anything that takes living space away. The hallway, corridor, guest toilet, and staircase should be designed space-efficiently. The living/kitchen area, Child’s room, and bedroom should be as spacious as possible within the tiny house footprint.
Air source heat pump, underfloor heating
The price is known, it has been compared, financing is secured.

As long as I have 11ant on my side, you can laugh all you want In the many discussions about locking bathroom doors, I have always pointed out that only someone without a paramedic among their friends would do such a thing. A door blocked by an unconscious person behind it is essentially the same as a locked door in this context ;-(

There is a dependency on the stairs. Only if we can place the stairs in such a way that we can still exit the attic at a point with enough headroom. At least in one design, that wasn’t possible. I don’t have any concerns about the one you showed here in post #25.

The plan shows a continuous wall section above the partition wall. Exactly, the drawing does show a gap between the “party walls,” but then both the outer shell and the insulation layer continue without interruption at the facades, which creates acoustic bridges.

The attic will serve as an office and guest room. Without the attic, the project That sentence kind of ends abruptly. I guess it means that the space would only be allowed as a storage room (where, of course, you can theoretically leave enough room around a desk to actually sit at it, and having a nice lamp and internet access is also not forbidden there)—I’ll leave the sentence hanging as well.

The attic will serve as a home office and guest room. Without the attic, the project would be significantly less comfortable and would not meet our requirements for living space. Cheers to the attic.
