Installed in Brentwood, a fiberglass plunge pool typically runs $33,500–$57,000 and a custom gunite plunge or spool $47,500–$85,500 — the small footprint saves on excavation and finish, but the equipment pad costs about the same as a full-size pool:
| Job | Typical Brentwood price |
|---|---|
| Precast concrete plunge pool, installed | $28,500–$52,500 |
| Fiberglass plunge pool, installed | $33,500–$57,000 |
| Custom gunite plunge pool | $47,500–$85,500 |
| Spool (spa + pool) with jets and heater | $57,000–$104,500 |
| Heater (year-round use) | $2,900–$7,600 |
| Chiller (cold plunge) | $3,800–$8,600 |
| Swim jets or resistance current | $5,000–$11,500 |
| Decking and coping | $4,000–$11,500 |
| Permits and inspections | $500–$2,900 |
Tennessee pricing is close to the national baseline used for these estimates. A plunge pool is not half the price of a full pool — the pump, filter, heater, electrical and permits are the same — but it fits where nothing else will and costs far less to heat and maintain.
A heater on a 4,000-gallon pool costs little to run — it is the difference between a plunge pool used eight months a year and one used eight weeks.

Gunite with sun shelves and spas leads new Nashville-area builds; vinyl liner remains the value king statewide, and fiberglass is growing fast for its quick spring installs. Covered outdoor living — fireplaces, kitchens — pairs with pools more here than almost anywhere. Smaller lots and higher construction costs have made plunge pools, cocktail pools and spools the fastest-growing pool type — a heated 8×16 pool costs a fraction to run and fits a courtyard.

Measure the access route first — a crane over the house changes the budget. Decide on heat, jets and a bench up front, since they drive the equipment. Then compare a fiberglass model against a custom gunite price for the same footprint. Tennessee requires a state contractor license for larger residential projects — most full pool builds qualify, so verify the license and its monetary limit along with insurance. Local codes govern pool permits and barrier fencing, and Nashville-area HOAs frequently add architectural review.
Installed in Brentwood, TN, a fiberglass plunge pool typically runs $33,500–$57,000, a precast concrete plunge $28,500–$52,500 and a custom gunite plunge $47,500–$85,500. A spool with jets and a heater runs $57,000–$104,500. Decking adds $4,000–$11,500 and a heater $2,900–$7,600. Tennessee pricing is close to the national baseline used for these estimates.
Most are 7 to 10 feet wide, 12 to 20 feet long and 4 to 6 feet deep with a flat floor — about 2,000 to 6,000 gallons versus 15,000 to 25,000 for a typical family pool. Cocktail pools add benches and a tanning shelf; spools are often 8×14 to 10×20 with spa jets.
You can cool off, float, soak and exercise in place; laps need a swim-jet or resistance-current system, which many plunge and spool builders install. For actual lap swimming a narrow lap pool of 30 feet or more is the better fit.
Much cheaper: a third or less of the water means a smaller pump, far less chemical use and a heater that brings the pool to temperature in an hour or two. Many owners here keep a plunge pool heated through the shoulder seasons and close it only in deep winter.
The outdoor season in Brentwood runs May through September — about 5 months unheated, with a heater adding several weeks on each end. Winters are mild enough that many owners idle equipment with a partial close instead of a full winterization. Tennessee swims May through September, with humid 90° summers and high algae pressure. Colder weather sends most pools into a full or partial close by early November, and spring storms add debris cleanup to the opening schedule.
Nashville Dip Pools has the highest customer rating on this Brentwood list at 5 stars across 11 reviews. Clearwater Pools has the largest review count (210 reviews at 3.9 stars). PoolPad orders the list with a weighted score that combines customer rating and review count, so a long track record counts for more than a handful of scores.
In most cities yes — any pool more than 18 to 24 inches deep needs a permit, electrical inspection and a barrier, regardless of footprint. Setbacks from property lines and the house decide where a small pool can go. Tennessee requires a state contractor license for larger residential projects — most full pool builds qualify, so verify the license and its monetary limit along with insurance. Local codes govern pool permits and barrier fencing, and Nashville-area HOAs frequently add architectural review.
A fiberglass or precast plunge pool is often swimmable one to three weeks after excavation; a custom gunite plunge takes six to ten weeks because the shell has to cure before the finish. Permits add time up front, and the deck follows the pool.
