Average spool pool cost

A spool pool costs $20,000 to $40,000, including delivery and installation. A budget backyard spool pool for family enjoyment costs $10,000 to $15,000. High-end spool pools cost $35,000+ with stronger swim currents for athletes and serious swimmers. Above-ground spool pools cost less than inground installations.

Average spool pool cost
Level Average installed cost Best for
Budget models $10,000 – $15,000 Family enjoyment and occasional water exercise
Mid-range models $20,000 – $40,000 Swimming and aquatic fitness
High-end models $35,000 – $65,000 Athletes and serious swimmers

Budget spools

Budget-friendly spools range from $10,000 to $15,000 for a swim spa with basic designs and limited features. They are typically smaller, ranging from 10 to 15 feet in length. Most offer one or two swim jets for resistance and often rely on cheaper materials and components, resulting in a shorter lifespan.

Mid-range spools

Mid-range spools cost $20,000 to $40,000 for a swim spa with a more spacious swim area and enhanced features. Ranging in size from 15 to 18 feet in length, mid-range spools offer a wider variety of features such as hydrotherapy jets, LED lighting, and improved energy efficiency.

High-end spools

The most expensive spool models, costing $35,000 to $65,000+, are usually larger and offer a better swimming experience. High-end spools feature a large swimming area, often 20 to 30 feet in length, with top-of-the-line materials and craftsmanship. Other luxury features include:

  • Superior insulation and energy efficiency for reduced running costs

  • Advanced hydrotherapy jets for better hydro massage functionality

  • High-end LED lighting and audio-visual systems

  • Better ergonomics

  • Extended warranties

Spool pool cost by type

Depending on your budget and preferences, you can choose between an above-ground or an inground spool installation. Above-ground swim spas are cheaper and easier to install, while inground spools appear more luxurious, and aesthetically pleasing.

Spool pool cost by type
Spool type Average installed cost
Above-ground $10,000 – $40,000


$25,000 – $75,000

Inground spool

Inground spools are more expensive and difficult to install, costing $25,000 to $75,000. They are typically made of concrete or fiberglass and are installed in the ground, just like a traditional swimming pool. This gives them a more permanent and finished look that lasts longer.

Inground spools can range in size from 15 to 30 feet long and 4 to 5 feet deep. They typically use a jetted pump system to circulate water through the pool, creating a more powerful swim current than a jet propulsion system.

Above-ground spool

An above-ground spool, or swim spa, costs $10,000 to $40,000 to install on top of the ground. Installation is affordable since no excavation is required. However, above ground spools are not as durable or as aesthetically pleasing as inground spool installations.

Above-ground spools are typically made of fiberglass or acrylic and sit on top of a concrete slab which costs extra. Above-ground swim spas are usually 10 to 20 feet long and 4 to 5 feet deep. They typically use powerful jets to push water through the pool, creating a strong swim current.

Endless Pool

An Endless Pool costs $26,000 to $75,000 with delivery and installation. Endless Pools manufacture a variety of swim spas that can be installed above ground, partially inground, or completely inground. This well-known brand costs more than other lesser-known brands, but their solid reputation and high-quality products are worth the price.

Spool pool cost by material

The cost of a spool varies significantly based on the materials used. Concrete spools are the most durable and customizable but cost more than other common spool materials. Molded acrylic is the most common material using jet propulsion, while steel and fiberglass spools use a motor for current.

Spool pool cot by material
Material Average installed cost Overview
Concrete (Gunite) $25,000 – $75,000
  • Most durable
  • Highly customizable
Acrylic $10,000 – $30,000
  • Easily installed prefab options
  • The least expensive but least durable choice
Fiberglass $15,000 – $40,000
  • Less expensive and easier to install than concrete
  • Not as durable as concrete
Steel $20,000 – $50,000
  • Expensive option
  • Often used for commercial applications, such as hotels or resorts
Cedar $5,000 – $10,000
  • Low cost but high maintenance
  • Often used in DIY installations
Copper $50,000+
  • Durable and luxurious materials
  • Used for high-end residential spools

Spool pool installation cost factors

The cost of installing a spool can vary widely, depending on several factors, including:

  • Size – Larger swim spas cost more for the materials and take longer to install, increasing costs.

  • Location – Above-ground spools are cheaper to install since no excavation is required.

  • Features – High-end features like LED lighting, sound systems, and mobile app functions cost more.

  • Materials – Concrete and steel are more durable and costly. Fiberglass and acrylic are more common and affordable.

  • Swim current – Jet propelled currents are the most common and inexpensive. Propeller propulsion systems are more expensive and produce a smoother, more consistent current for advanced swimmers and athletes. Paddlewheel systems are the most expensive but provide a smooth, stable, and quiet current.

  • Insulation:

    • Full foam insulation – A more expensive insulation method that fills the entire cavity between the spa’s shell and cabinet to create a tight seal and minimize heat loss

    • Partial foam insulation – A cheaper approach that insulates only specific areas of the spa with foam, rather than the entire cavity, which costs less

    • Reflective insulation – A supplemental material used along with other insulation methods to further improve energy efficiency

    • Cover insulation – While not part of the spa itself, a well-insulated cover is essential for energy efficiency. A high-quality cover with foam insulation costs more but retains heat better.

Delivery & installation

Spool delivery costs $100 to $1,500, depending on the size and location. The highest costs are for deliveries that require an overhead crane or for inground installations that require excavation. Common installation costs include:

  • Monthly energy costs to run a swim spa average $20 to $80+ per month, depending on the size and how often the swim spa is used.

  • Ongoing spool maintenance costs $50 to $300 per month on average, depending on the quality of your spa. High-end spas often have better purification systems and require less maintenance.

Spool pros and cons

Spools offer a small, compact footprint with a lot of features. The current allows you to swim for exercise, while the heated soaking and hydrotherapy jets are perfect for relaxation. The small spool is also easier and cheaper to maintain than a larger traditional swimming pool.

Spool vs. pool cost

A small spool is not for everyone. A spool usually has just enough space for one or two people to swim comfortably.

If you have a larger yard and family, you may prefer a full-sized inground pool costing $25,000 to $100,000. Nearly twice the size of a spool, a traditional pool gives you more space for large parties and pool games.

Spool pool FAQs

What is a spool pool?

A spool pool is a hybrid between a spa and a pool designed for both swimming and hydrotherapy. A spool is smaller than a traditional swimming pool, but large enough to swim in thanks to the water current you can swim against.

How deep is a spool or swim spa?

A swim spa, or spool, is 4 to 5 feet deep. This depth is ideal for swimming, water exercise, and aqua therapy. Deeper pools up to 6 feet deep are available at a higher cost for more serious swimmers and athletes.

How long does a spool last?

A spool lasts between 8 to 15 years on average. The quality of the spa, how well it is maintained, and how frequently it is used can all affect the lifespan of your spool.

Where can you put a spool?

You can put a spool in your backyard, on your patio, in your garage, in a basement, or in a sun room. You may be able to put a spool on your deck, if the deck is large enough and can support the weight of the 2,000 gallons of water.

Where can you buy a spool or swim spa?

You can buy a spool at online retailers, local swim spa dealers, hot tub stores, or directly from swim spa manufacturers.

Getting estimates from spool pool installers

Here are some guidelines to help you choose a spool installer near you:

  • Look for a spool installer that’s been in business for 5+ years.
