Precast concrete plunge pools: cost, sizes and makers
By the Renology editorial team · Reviewed by Dror Gigi, Co-Founder · Facts checked
The short answer
A precast plunge pool is a small concrete pool poured, finished and fitted in a factory, then delivered in one piece and set by crane. As of October 2026, Soake lists its models at $25,000 to $33,500 with equipment, and Plungie's own guide puts precast shells at $20,000 to $35,000 and installed projects at $40,000 to $54,000 and up. A Soake partner in Texas reports finished projects at $65,000 to $95,000. Most are 4 to 5 ft deep and 7 to 20 ft long.

What a precast plunge pool is
The pool is cast in steel-reinforced concrete at a factory, finished with tile or a coating, and fitted with its light, returns and skimmer before it ships. It arrives on a flatbed and a crane sets it, partly in the ground, flush with a patio or fully above ground. Plunge pools are made for cooling off, soaking and, with a heater or chiller, hot or cold plunging, not for swimming laps.
What it costs
Soake publishes a price for each model: $33,500 for its 13 x 7 ft Full Plunge, $31,000 for the Medium, $32,500 for the Square and $25,000 for a cold plunge, including a salt system, pump, filter, light and automation. Delivery, a heater, the crane, site work and permits are extra.
Plungie's own guide lists the add-ons: a crane at $3,000 to $10,000, permits at $450 to $1,800 and electrical at $1,500 to $4,000 or more. A Soake partner in the Dallas area puts finished projects at $65,000 to $95,000, with excavation and an engineered base at $9,000 to $14,000.
Weight decides the crane
These pools are heavy. Plungie's models weigh 14,600 to 25,600 lb dry, and Dirigo's larger pools can reach about 45,000 lb. The crane has to reach the spot from the street, so the distance and whether the pool must go over the house drive the crane bill. Ask the maker for the weight and a lifting plan before you get crane quotes.
Heating and cold plunging
Most makers offer a gas heater or an electric heat pump, and some offer a chiller for cold plunging. Soake says its panel typically needs a 50 amp circuit, and more with a heat pump, so include an electrician in your budget.
Permits and safety
A plunge pool is still a pool. California counts any structure holding water over 18 inches deep as a pool, so a new one at a home needs at least two of seven drowning-prevention features under the rules in force since 2025, such as a 60 inch enclosure, a safety cover or alarms. Other states and towns set their own rules; some treat a small plunge pool like a spa. Ask your building department before you order.
Precast concrete vs a fiberglass plunge pool
Several fiberglass makers sell plunge models too, usually 8 x 14 to 8 x 16 ft, installed by their dealers. Precast concrete gives a tiled, heavier, more architectural pool that can sit above ground; fiberglass is lighter and is usually set in the ground with a dealer handling the whole job.

The part a pool price leaves out
Get your yard checked by a local pool contractor
Crane access, excavation, the pad, electrical, fencing and permits decide most of the gap between a pool price and a finished backyard. In Southern California, the Bay Area and Greater Seattle, we can introduce you to 2 to 3 licensed pool contractors who can walk your yard and price that part.

Frequently asked questions
How much does a plunge pool cost?
Precast concrete plunge pools list at about $25,000 to $34,000 for the pool and equipment (Soake, October 2026). With delivery, crane, site work and permits, finished projects commonly run $40,000 to $95,000 depending on access and finish.
What are the disadvantages of a plunge pool?
It is too small for laps, a precast one needs a crane, and heating it adds running cost. Permits and fencing rules usually still apply.
How long does a precast plunge pool last?
Concrete shells are built to last decades. Published structural warranties in this category run 10 to 15 years where makers publish them.
Can a plunge pool be above ground?
Yes. Precast pools such as Soake's can sit fully above ground, partly in the ground or flush with the patio.
