Natural swimming pool styles compared
| Style | What it looks like | What to know |
|---|---|---|
| Swimming pond | Large, curved, irregular water with a planted shallow zone and a gravel or rock beach | Needs the most space, because the planted zone takes up part of the area; suits a larger yard or a country plot |
| Plunge pool | Small, often round or oval, stone-edged water you cool off in rather than swim laps | Works in a small yard; sits well near the house or a deck |
| Converted pool | An existing pool changed to run on plants instead of chemicals, with the edge softened | A builder has to check the shell, the pump and the plant zone; the AI only shows the new look |
| Formal natural pool | Straight or geometric edges with paving, and plants held in a neat band | A crisp look that fits modern houses; the plants still do the cleaning |
| Pool with timber deck | A wood deck or platform at the edge for sitting and stepping in | The natural look of timber suits an organic pond; see our deck pages for materials |
| Pool with rock and waterfall | Boulders, a stacked stone wall or a small waterfall at one end | Moving water helps keep the pond fresh; pumps and electrics need a qualified installer |
These are the layouts the guides ranking for this search keep showing. The table says what each one looks like and the main thing to know before you pick it. Many yards end up combining two of them.
How a natural swimming pool keeps the water clean
The guides describe the same idea: the water is split into a swimming zone and a planted regeneration zone. Plants and the bacteria on their roots and on gravel take up the nutrients that algae would otherwise feed on, and a pump moves the water through the planted zone and back. There is no chlorine.
- Swimming zone: The open, deeper part you swim in. Its edge is usually stone, gravel or timber.
- Regeneration zone: A shallower area full of aquatic plants and gravel that filters the water. Builders quote different sizes for it, from about a third of the swimming area up to the same size, so ask a pool builder who has built natural pools in your climate.
- Pump and skimmer: They move the water through the plants and take leaves off the surface. Some designs add a small waterfall for extra movement.
- No fish: Poolscape, quoted by Gardeningetc, advises against keeping fish in a natural pool because their waste is high in nutrients.
