Pool shape

Kidney

The free-form classic — a pool that looks grown, not built

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.

Trade-offs

No straight swim lane
Curved formwork and coping raise build cost
Rectangular covers don't fit — custom only
