8 × 3.5 m Roman
pool plan
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 Roman pool pairs a rectangular body with semicircular ends, a silhouette borrowed from classical baths. You keep an honest swim lane down the middle while the ends soften the geometry and make natural places for steps — a Roman staircase flowing out of the curved end is the signature move.

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 8 × 3.5 m pool hold?
- About 37.6 m³ (37.6 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 25 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 25.4 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.
