Six Bedrooms, One Bathroom: Why Older Durban Houses Run Short

A great deal of bathroom renovation work in Durban is not really about replacing a bathroom. It is about finding room for another one.

That is not a modern failure of planning. It is the direct result of how substantial houses in Natal were built, and it is visible in the historical record of the houses themselves.

The bedroom count and the bathroom count were never proportional

Descriptions of large Natal houses list their rooms in detail, and the pattern is consistent enough to be worth noticing. One property recorded in the Natalia archive — a substantial house set in several acres — is described as having four large reception rooms, six bedrooms, a kitchen, a larder and a butler’s pantry.

And one bathroom.

That ratio is not an oversight by the standards of the time. A bathroom was a serviced room: it needed a water supply, a means of heating that water, a waste route, and a structure that could tolerate moisture. Every one of those was expensive and awkward to duplicate. Bedrooms could be added by building more rooms. Bathrooms could not.

So the house grew in the direction that was cheap to grow in, and the servicing stayed concentrated in one place.

What that means when you open the walls

If you own one of these houses, the consequences are practical rather than historical.

The original bathroom is usually in the part of the plan where the services were easiest to run, not where you would put it today. It is often adjacent to the kitchen, or backing onto it, because that is where the supply and waste already were. It is frequently one of the smaller rooms in a large house.

That produces the situation we see repeatedly:

• The obvious place for a second bathroom has no services near it. The bedroom that most wants an ensuite is usually the one furthest from the original wet core.
• Waste is the constraint, not water. Getting a supply pipe to a new position is comparatively easy. Getting waste to fall correctly, to an existing stack, through an existing floor structure, is what decides whether a layout is possible.
• The floor build-up varies across the house. A room that was never a wet area may sit on a different structure to the original bathroom, at a different level, with different tolerance for the build-up a modern shower needs.
• The original bathroom is often worth keeping where it is. Moving it to gain a better layout can mean rebuilding the one part of the house that already works.

None of this is a reason not to add a bathroom. It is a reason to establish the waste route before deciding on the layout, rather than after.

The mid-century shift: a bathroom as a stated standard

By the middle of the twentieth century the expectation had changed, and it had changed explicitly. Housing described in Natal periodicals of the early 1950s specifies the bathroom as part of the defined standard of a house: a lounge, two bedrooms, a kitchen, and a bathroom with a bath and hot and cold water.

That is a much smaller house than the six-bedroom example above. But the bathroom is no longer a luxury attached to a large property — it is written into the specification of an ordinary one, with the hot water stated as part of it.

The same period’s writing also shows how a bathroom could still signal wealth at the other end of the scale. One account describes a bathroom with a bath so large it is compared to a miniature swimming pool, with hot and cold water laid on. The language tells you that this was still remarkable enough to be worth describing.

Within a few decades, then, the bathroom moved from a single serviced room in a grand house to a stated minimum — while remaining, at the top of the market, something people wrote about.

Why the history is useful rather than decorative

A renovation brief that begins “we want an ensuite off the main bedroom” is really a question about services. The house will answer it, and the answer was largely determined when the house was built.

Before committing to a layout, it is worth establishing:

• where the existing soil stack runs, and whether it can take another connection;
• what fall is available between a proposed new waste and that stack;
• whether the floor structure in the proposed room is slab, screed or timber;
• whether the wall behind a proposed wall-hung basin or toilet can carry a frame;
• how the new room will be ventilated, and where that air will go;
• whether the hot water system can serve another outlet at usable pressure;
• what the original bathroom’s services will look like once opened.

A house with six bedrooms and one bathroom is telling you something about itself. Reading it early is cheaper than discovering it during demolition.

Thirty-five years of the same conversation

Richard McKie’s work began through Reno Incorporated roughly 35 years ago, and a substantial share of it has always been this: fitting another bathroom into a house that was designed around one.

The materials have changed completely. Large-format porcelain, concealed cisterns, wall-hung frames and modern waterproofing systems did not exist in the houses where this problem started. The underlying constraint has not changed at all. Water is easy to bring. Waste decides the plan.

Research note

This article was informed by historical material in the Natalia archive of the Natal Society Foundation, including descriptions of Natal houses and their room arrangements, and by mid-century Natal periodical material describing housing standards and bathroom provision.

Individual houses are cited as historical examples, not as a universal account of Natal building practice. Room descriptions in the historical record vary in detail and completeness, and a single recorded house does not establish what was typical.

Richard McKie’s practical perspective reflects his work through Reno Incorporated and Signature Bathrooms. It does not replace a property-specific inspection, structural assessment, or professional plumbing and electrical advice where those are required.
