Installed in Indianapolis, a fiberglass plunge pool typically runs $35,000–$60,000 and a custom gunite plunge or spool $50,000–$90,000 — the small footprint saves on excavation and finish, but the equipment pad costs about the same as a full-size pool:
| Job | Typical Indianapolis price |
|---|---|
| Precast concrete plunge pool, installed | $30,000–$55,000 |
| Fiberglass plunge pool, installed | $35,000–$60,000 |
| Custom gunite plunge pool | $50,000–$90,000 |
| Spool (spa + pool) with jets and heater | $60,000–$110,000 |
| Heater (year-round use) | $3,000–$8,000 |
| Chiller (cold plunge) | $4,000–$9,000 |
| Swim jets or resistance current | $5,000–$12,000 |
| Decking and coping | $4,000–$12,000 |
| Permits and inspections | $500–$3,000 |
Indiana 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.

Vinyl liner rules, fiberglass is the fast-growing second, and gunite holds the Carmel-and-Zionsville end of the market. Simple rectangles with tanning ledges and big patios fit the entertaining culture. 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. Indiana handles residential contractor licensing locally, so check insurance certificates and references and confirm a licensed electrician pulls the equipment permit. Pool permits and residential-code barrier requirements, including fencing and self-latching gates, run through the county or municipal building department.
Installed in Indianapolis, IN, a fiberglass plunge pool typically runs $35,000–$60,000, a precast concrete plunge $30,000–$55,000 and a custom gunite plunge $50,000–$90,000. A spool with jets and a heater runs $60,000–$110,000. Decking adds $4,000–$12,000 and a heater $3,000–$8,000. Indiana 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 Indianapolis runs late May through mid-September — about 4 months unheated. A full professional winterization each fall protects plumbing and equipment through the freeze, and spring openings cluster into the same few weeks. Late May through mid-September, hot and humid at the peak. Winters freeze hard; October closings and April openings bookend every year.

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. Indiana handles residential contractor licensing locally, so check insurance certificates and references and confirm a licensed electrician pulls the equipment permit. Pool permits and residential-code barrier requirements, including fencing and self-latching gates, run through the county or municipal building department.
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.
