Pool type
Lap pool
Long, narrow, swim-fitness focused — almost always concrete.
12–25 metres long, 2.5–3.5 metres wide, depth set for proper freestyle stroke. Lap pools are concrete by default — fibreglass shells don't extend to lap lengths, and the linear shape works architecturally with side gardens or terrace runs. Most NZ lap pools are heated to 28°C year-round so the swim-fitness use-case actually works.
