How much water does a 12 × 7 m pool hold?

About 115.1 m³ (115.1 tonnes of water) at 1.2–2.0 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 76.8 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.

About this pool

An estate-class pool: resort presence at home, with room for swimming, play and lounging at the same time. At this size the supporting decisions matter as much as the basin — plan generous decks, a solid heat source and an automatic cover from day one, because every square metre of water is heated, treated and covered.

The lazy L angles the junction between its two legs instead of meeting at 90°, which relaxes the whole composition. You get the L-shape's zoning — swim leg plus shallow leg — with a softer, more organic footprint that sits comfortably in informal gardens and on sloping sites.

The numbers, computed

Water surface: 76.8 m²
Water volume: 115.1 m³ (115,103 L)
Perimeter: 35.4 m
Depth: 1.2–2.0 m
Excavation approx.: 177 m³
Fill time (garden tap): 3 days
