My friend has an outhouse attached to her house and is currently in the process of knocking a hole through the kitchen wall direct to the outhouse and turning this into a toilet/bathroom.
This will mean that when finished she can open one door from the kitchen directly into the bathroom. Are there not health and hygiene regulations that state two doors should be between the kitchen and the new bathroom?
What the Rules Actually Say
There is no outright ban on having a door that opens directly from a bathroom into a kitchen. The building regulations for England and Wales do touch on hygiene, but they are less prescriptive than many people assume.
It was once common practice to require two doors between a toilet and a kitchen. Some believe this was a formal requirement in older versions of the building regulations. Others think it was simply a widespread interpretation that became accepted as fact. Current guidance does not demand two doors.

Part G of the building regulations covers sanitation, hot water safety and water efficiency. It sets out requirements for bathrooms, toilets and wash basins, but it does not specifically prohibit a direct door between a bathroom and a kitchen in a domestic property. Part G focuses on the provision of facilities rather than door placement between rooms.
The key practical point is that any room containing a toilet should have a wash basin. This can help address hygiene concerns by allowing handwashing before moving into other parts of the home. As long as a basin is provided within the bathroom, most building control officers will consider the arrangement acceptable.
Commercial kitchens and food premises follow stricter rules under food safety legislation, but these do not apply to ordinary homes.

Local Authority Interpretation
Building control officers apply the regulations as written, though they may have flexibility in how compliance is achieved. What one authority accepts without question may prompt a conversation in another. If you are planning an extension or conversion that would create a direct door between a bathroom and kitchen, check with your local building control team early on.
They can confirm whether your proposed layout will meet approval or whether you may need to adjust the design. Most extensions and internal alterations require building regulations approval, so this step is usually necessary regardless.
Practical Considerations
Even where regulations allow it, a direct opening from bathroom to kitchen may not be ideal. Smells, moisture and noise can all transfer more easily without a buffer zone. Some homeowners find that a short corridor or lobby makes the layout feel more comfortable.
If space is tight, a pocket door, improved ventilation or careful positioning of fittings may reduce practical drawbacks.
When selling a property, an unusual layout could raise questions from buyers or surveyors. Consider how the arrangement will be perceived in the longer term.
Building regulations are updated periodically, so always verify current requirements before starting work. For the latest wording of Part G and other approved documents, visit GOV.UK and search for "building regulations approved documents." Your local authority building control service can also confirm how the regulations apply to your specific project.

To block up! Is this possible? Could the kitchen sinks be connected to the toilets in any way?
