Compact gunite pools and pool-and-spa combos, designed for the tract lots and awkward yards a full-size pool does not fit. Planning range from about $60,000.

Scope
Process
Pick the plunge or spool type in the calculator. It scales the base by 0.72 and shows its work.
Free visit. The design session works around setbacks, slopes, and odd lot lines first, finishes second.
Same permit package and HOA submission as a full pool. Small pools are still pools to the building department.
Typically 8–12 weeks of construction after permits, with a named project manager and stage updates.
Market ranges
| Tier | What it describes | Planning range |
|---|---|---|
| Spool | Pool and spa in one compact body of water, heated, with jets and bench seating | $60,000–$90,000 |
| Plunge pool | Compact swimming pool, flat depth profile, bench seating, no spa function | $62,000–$95,000 |
| Plunge pool with spa | Compact pool plus a separate spa body, two volumes of water | $80,000–$110,000 |
| Full-size custom gunite | For comparison: the standard 14 x 28 to 16 x 32 ft family pool | $90,000–$165,000 |
Planning ranges for the Conejo Valley market, updated October 2026, consistent with the tier table on the cost guide. Hillside access, narrow gates, and rock move a small pool the same way they move a big one.
Cost drivers
Small yards often mean narrow side-yard gates. The calculator prices narrow access at $5,000–$12,000 because excavation gets smaller, slower, and more manual. It is the classic small-lot line item, named up front.
A spool heats like a spa, so the heater and controls are specified for spa duty, not shrunk with the shell. It is why a spool costs 0.72 times a full pool and not half.
Small pool questions
Most local spools and plunge pools land between 8 x 16 ft and 12 x 24 ft of water. A spool is the pool and spa in one body of water, heated like a spa. A plunge pool is a compact swimming pool, usually with a bench and a flat depth profile for soaking, games, and a quick swim.
Yes. Health and Safety Code §115922 does not have a small-pool exemption: a new pool or spa at a single-family home needs at least two of the seven approved drowning prevention safety features, verified before final inspection. The enclosure rules at §115923 apply the same way.
Permitting runs the same 4–8 weeks as a full-size pool; the permit office does not discount for size. Construction runs shorter, typically 8–12 weeks, because excavation, steel, and gunite volumes shrink while the equipment set stays similar.
It feels like a small one, because it is one. You soak, you cool off, kids play, nobody swims laps. For a lot of Conejo yards, the trade is right: a spool leaves room for deck, planting, and the rest of the yard, at roughly 0.72 times the cost of the same footprint built as a full pool in the calculator's math.
