7.5 × 4.2 m Kidney
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 kidney is the archetypal free-form pool: one flowing bean-shaped curve with a waist that invites planting, a boulder or a slide. It blends into naturalistic landscapes better than any straight-walled shape and makes small gardens feel bigger because the eye never finds a hard boundary.

Questions about this plan
- How much water does a 7.5 × 4.2 m pool hold?
- About 27.1 m³ (27.1 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 18 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 17.9 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.
