How much do swim spa enclosures cost?
Do the costs vary? Let’s find out.

Typically, a Swim Spa Enclosure costs around $5 to $15 per square foot. The total average cost of installing the enclosure ranges from $4,000 to $15,000. In some cases, it may add up to $70,000 or more. The cost might vary due to many factors, such as size, design, frame material, etc.

However, these are just estimations. It is necessary to know the exact costs of building a swim spa enclosure. So, we’ve done some extensive research to add enough information about it.

Average Cost of Swim Spa Enclosures

On average, the cost of a swim spa enclosure is around $10,000. It ranges from $4,000 to $15,000, including the frame costs. On the other hand, the average cost of premium swim spa enclosures are around $35,000 to $70,000. The premium ones include enclosures made of glass and other expensive materials.

There are six types of swim spa enclosures, and they have significant differences in their average costs. Generally, we can find screen, inflatable, polycarbonate, glass, retractable, and custom swim spa enclosures.

Inflatable dome kit and screen swim spa enclosures cost around $10,750. Usually, their price ranges between $7,500 and $14,000. They are quite affordable relative to other enclosures.

Secondly, purchasing a polycarbonate will cost you above $11,000. It ranges between $8,000 and $30,000. The fact that polycarbonate enclosures are much more durable than other enclosures justifies their price. It costs $15 to $45 per square foot, depending on other factors.

Glass enclosures average price range starts from $15,000 to $50,000, costing $30 to $65 per square foot. Due to their high setup costs, they can barely cost lower than $15,000.

Lastly, the average cost of custom or retractable is about $90,000. Due to its price, people rarely purchase them. Usually, stores charge $40 to $100 per square foot for customized enclosures, while they charge $20 to $200 per square foot for retractable enclosures.

Factors Influencing the Cost

Several factors influence the cost of swim spas enclosures. These include its size, material, and height.


Sizes or measurements are necessary when calculating swim spa enclosure costs. A swim spa of 15 inches wide by 30 inches long will cost less than an enclosure of 30 inches wide by 50 inches long. Stores calculate their cost as per square foot. For instance, screen swim spa enclosures of 15 by 30 inches cost around $3,500 to $15,500, while they cost $7,500 to $20,000 or more when they are 30 by 50 inches.

Material of the Swim Spa Enclosure

The cost of the material or transparent sheet of the spa enclosure varies. The average cost of a screen swim spa enclosure per square foot is about $14, while a glass swim spa enclosure is around $55. Another one, the retractable swim spa enclosure will cost more than $100.

Such expensive frames and glazing will only increase its costs. Adding other extra tinted or insulated covers to these frames can add to a further increase in expenses.


The height of the swim spa can make significant changes to its average cost. A regular swim spa of $15,000 may cost above $20,000 due to its extended length. Generally, swim spas have a height of about 7 inches. Building a swim spa taller than 14 feet will add to the cost of purchasing tall frames and glazing.

Are Spa Enclosures Worth It?

Spa enclosures are relatively expensive, but it's a small price to pay for tons of fun. Unlike swimming pools, spas with enclosures can be used for all four seasons. It also protects the swimmers from harmful UV rays.

It's an escape from the stressful schedule of life. Due to the variations in size and features, it's possible to purchase and customize as per requirements. You can either have a tinted or protected sheet with insulation properties to avoid harmful UV rays. Such a cover will also help maintain privacy at the highest levels.

It might also require you to refill the water in the swim spa less often. It's because the spa enclosure reduces evaporation loss. Additionally, during winter, when there's solar radiation attached, it can lower thermal losses to capture heat. It will eventually keep the swim spa warm. Thus, regardless of their price, spa enclosures are worth it.

Building Process of a Salt Water Swim Spa Enclosure

Knowing how your swim spa enclosure will be installed is essential as well. Sure, you might hire a professional to do it. But, understanding how the project will be completed is a must.

So, here’s how the complete building process will go.

  • For building saltwater swim spa enclosures, the exact measurements of the swim spa’s width and length are important. According to the correct measurements, a pool decking using sturdy materials such as concrete, patio bricks, or decking needs to be set up. The structure is set under the swim spa.
  • Next, holes are dug according to the support posts of the swim spa enclosure. They need to be deep enough to support its footers. After digging enough, the footers are inserted to secure it with concrete.
  • Once the footers are secured, the swim spa enclosure is installed. Enclosures that include glass panels need attention while installing; they are very fragile.
  • Lastly, since every enclosure has unique settings, different enclosure kits, and their instructions require a different type of installation.

I can build it, and I can help you get the patio enclosure you want! I got my start in the Florida patio industry back in the 70s as a young general laborer looking for something to make a few bucks. At the time I never thought it would end up as my career. Over the years I grew beyond the laborer position, becoming a foreman, superintendent, and then into executive management for some of the largest patio contractors, and material vendors. Now into retirement and slightly bored, I offer consulting services to new and existing contractors, and publish this website to help the people who love their patio's and screen enclosures the most - YOU!
