Should I build a pool or a spool?
Pick by how you actually use water. A spool wins on cost, footprint, year-round use, and warm soaks. A pool wins on swimming, multiple swimmers, and the social/visual center of a yard.

Pick a spool when
- You want hot soaks most of the year, plus a cool-off in summer.
- Yard space is tight or the budget needs to land lower.
- You won't actually swim laps and don't host swim parties.
- You want heat-up time measured in minutes, not hours.
Pick a pool when
- Multiple swimmers, kids who'll grow up swimming, regular summer use.
- You want the pool to be the visual anchor of the yard.
- You need depth or length for play, fitness, or training.
Arizona context
- Spools run 95–104°F efficiently in Phoenix winters; full pools cost more to heat through cold snaps.
- Both require ARS 36-1681 / IRC barrier compliance — design accordingly.
When the answer changes
- Resale: in some neighborhoods a full pool is the expectation; in others a spool is a feature, not a compromise.
- Lot constraints (setbacks, easements, utilities) may force the answer.
