18 × 4 m Rectangular
pool plan
A lap-class pool: long, narrow and uniformly deep, built for exercise. The constant depth makes flip turns predictable and halves the excavation surprises; the narrow width keeps volume — and therefore heating — in check for the length you get.
The rectangle is the default for a reason: it gives you the most swimmable water for a given footprint, plays well with modern architecture and lap swimming, and makes covers, solar blankets and automatic cleaners simple. Straight walls also keep formwork and tiling straightforward, which builders appreciate.

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 18 × 4 m pool hold?
- About 97.2 m³ (97.2 tonnes of water) at 1.4–1.4 m depth — computed from the actual pool outline, not a rule of thumb.
- How long does it take to fill?
- Roughly 3 days 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 72.0 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.
