4 × 2.5 m Rounded rectangle
pool plan
This is a plunge-class pool: sized for cooling off, soaking and small-garden luxury rather than swimming laps. A uniform depth keeps the whole basin usable, heating it is quick and cheap, and it pairs beautifully with a deck-level overflow edge for a reflecting-pool look.
A rounded rectangle keeps almost all of the rectangle's swimmable water but rounds the corners into generous fillets. The result reads softer in a garden, is gentler on swimmers, and the corners no longer trap debris the way sharp ones do. It's the shape we default to in the designer.

The numbers, computed
- Water surface
- 9.8 m²
- Water volume
- 12.7 m³ (12,682 L)
- Perimeter
- 12.1 m
- Depth
- 1.3–1.3 m
- Excavation approx.
- 20 m³
- Fill time (garden tap)
- 8 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 4 × 2.5 m pool hold?
- About 12.7 m³ (12.7 tonnes of water) at 1.3–1.3 m depth — computed from the actual pool outline, not a rule of thumb.
- How long does it take to fill?
- Roughly 8 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 9.8 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.
