How much water does a 8 × 4 m pool hold?

About 44.9 m³ (44.9 tonnes of water) at 1.2–1.8 m depth — computed from the actual pool outline, not a rule of thumb.

How long does it take to fill?

Roughly 30 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 30.2 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.

About this pool

A full family pool: a shallow end where kids stand and games happen, a proper deep end for diving-free swimming, and enough length that two people can swim without negotiating. This is the most-built size class in private gardens for a reason.

The Grecian pool clips the rectangle's corners at 45°, giving an octagonal outline that reads formal and deliberate without a single curve. It keeps nearly all the rectangle's swim length, and the angled corners make elegant seats for steps, benches or planters at the pool's edge.

The numbers, computed

Water surface: 30.2 m²
Water volume: 44.9 m³ (44,901 L)
Perimeter: 21.8 m
Depth: 1.2–1.8 m
Excavation approx.: 69 m³
Fill time (garden tap): 30 hours

Heat pump size: 16 kW

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.
