Ø 4 m Round
pool plan
A compact family size: big enough for proper swimming strokes and games, small enough that heating, covering and chemistry stay cheap. In most gardens this class hits the sweet spot between water you use daily and garden you keep.
A round pool is the most social shape there is: everyone faces everyone, there's no deep-end hierarchy, and it drops into a small garden or courtyard without dominating it. It's the natural choice for cooling off, kids' play and spa-like plunge pools rather than lap swimming.

The numbers, computed
- Water surface
- 12.5 m²
- Water volume
- 17.2 m³ (17,224 L)
- Perimeter
- 12.6 m
- Depth
- 1.2–1.6 m
- Excavation approx.
- 27 m³
- Fill time (garden tap)
- 11 hours

Figures are computed from the sampled pool outline and the plan's depths — the same geometry the 3D designer uses. Excavation includes shell and working allowance; your site conditions may differ.
Questions about this plan
- How much water does a Ø 4 m pool hold?
- About 17.2 m³ (17.2 tonnes of water) at 1.2–1.6 m depth — computed from the actual pool outline, not a rule of thumb.
- How long does it take to fill?
- Roughly 11 hours from a standard garden tap (~1.5 m³/h). A water delivery service fills it in a few hours.
- Is this size right for my garden?
- The water surface is 12.5 m²; plan roughly 1.5–2× that footprint including the surrounding deck. Open the plan in the designer and set your own deck margins to see the full footprint.
- Can I change the depth or edge type?
- Yes — open the plan in the designer and adjust depths, edge system (skimmer, deck-level overflow or raised), finishes and accessories freely.
