How Much Does an Indoor Swimming Pool Cost: A Comprehensive Guide
Having an indoor swimming pool is a dream for many homeowners. It provides year-round enjoyment and adds significant value to your property. However, one question that often arises is, “How much does an indoor swimming pool cost?” In this detailed guide, we will break down the various factors that influence the cost of building an indoor pool and provide you with valuable insights to help you make an informed decision.
The cost of installing an indoor pool can range significantly, spanning from $10,000 to $200,000. This wide price range is influenced by various factors, particularly whether you are constructing a new enclosure or utilizing an existing structure. On average, you can expect to invest around $95,000 for this upgrade, with the final cost depending on the specific features of the pool and the architectural characteristics of your home. It’s important to note that indoor swimming pool costs differ substantially from those associated with installing a traditional backyard pool.

Here’s a breakdown of the cost spectrum:
- Low Cost: $10,000
- Average Cost: $95,000
- High Cost: $200,000
Breaking Down the Costs of Indoor Pool Installation
When it comes to installing an indoor pool, understanding the cost breakdown is crucial. Here, we’ll delve into the key components that make up the expenses associated with indoor pool installation:
Inground vs. Above Ground
Comparing the costs of different pool types is essential. Semi-inground or above ground indoor pools tend to be more budget-friendly than their inground counterparts. Above ground indoor pools typically range from $10,000 to $36,000, while inground indoor pools can vary significantly, from $20,000 to $200,000. Keep in mind that the latter price range doesn’t include the construction of an enclosure if you don’t already have one.
The higher costs of inground pools are attributed to excavation and the potential for custom design elements. Above ground pools, when placed indoors, are often prefabricated, making them more cost-effective.
Prefab vs. Custom
Your choice between prefab and custom pool designs will also impact the cost. Prefabricated pools, delivered in one or several pieces, typically cost between $20,000 and $90,000. While some parts may have higher shipping costs due to their size, opting for prefabrication can save you money in design fees.
Custom pool designs, on the other hand, offer limitless possibilities but come at a higher price. Expect to pay anywhere from $30,000 to $110,000 or more for custom pools. Customization options include unique pool shapes, varying depths, and additional features such as steps, ladders, and currents.
Materials
The choice of pool material plays a significant role in the overall cost. There are three main types of pool liners: vinyl, concrete, and fiberglass. Here’s a breakdown of each material and its associated costs:
- Concrete: Concrete indoor pools generally range from $20,000 to $90,000. They are available in both custom and prefabricated designs, often shipped as precast shapes. With proper maintenance, concrete pools can last up to 75 years.
- Vinyl: A vinyl pool will typically cost between $30,000 and $65,000. These pools are constructed on-site due to the nature of the material. While they are relatively easy to maintain, you’ll need to budget for periodic replacement of the vinyl pool liner, which costs around $2,300 and occurs approximately every 10 years.
- Fiberglass: Fiberglass indoor swimming pools, a popular choice, range from $40,000 to $85,000. They often come in prefabricated designs that, while less customizable than concrete, offer quicker and easier installation. Fiberglass pools have an average lifespan of 25 years, making them a durable and relatively low-maintenance option.
Size Matters
The size of your indoor pool significantly affects the overall cost. On average, indoor pools are priced between $70 and $315 per square foot. However, this cost can vary depending on whether you opt for a prefabricated or custom-made pool. Standard pool sizes are generally more cost-effective per square foot compared to unique shapes and depths. Here are some common indoor pool sizes and their estimated costs:
- 12 by 20 ft.: $16,700–$75,000
- 12 by 24 ft.: $20,000–$90,000
- 16 by 32 ft.: $35,600–$160,000
- 20 by 40 ft.: $55,600–$250,000
- 30 by 50 ft.: $104,000–$470,000
Understanding these cost components will help you plan and budget effectively for your indoor pool installation project. Keep in mind that your choices in terms of pool type, customization, materials, and size will ultimately determine the final price tag.
Dehumidification Systems for Indoor Pools
Maintaining the ideal humidity level of 30% to 50% in your home can be quite challenging when you have a large indoor pool. All indoor swimming pools require a reliable dehumidification system, even if your pool is situated within a separate enclosure.

Whole-Home Dehumidifier
If your indoor pool shares space with your home, such as in the basement, an enclosed patio, or a designated room, a whole-house dehumidifier is a suitable choice. These systems typically range from $1,300 to $2,800 on average. However, for larger pools and enclosures, the cost can extend to as much as $8,000.
Ventilation-Based System
Ventilation dehumidifiers, priced between $4,000 and $10,000, operate by using outside air to regulate the environment within the pool enclosure. This method helps in maintaining balanced humidity levels. It’s worth noting that this system may not be ideal for regions with hot and humid summers unless you incorporate a refrigeration component.
Mechanical Refrigeration
Mechanical refrigeration stands as the traditional and most effective dehumidification system for indoor pools, even though it is the most costly. These systems typically range from $4,000 to $20,000. Similar to ventilation-based systems, mechanical refrigeration units draw in external air, which is then passed over a refrigeration coil to cool it down and eliminate excess humidity. This method ensures a comfortable and controlled pool environment.
Electrical and Plumbing Requirements
Ensuring your pool enclosure has adequate electrical and plumbing provisions is crucial for its proper functioning. The expenses in this category can vary based on factors such as your pool’s size, its proximity to existing plumbing and electrical outlets in your home, and any unique pool features. Here’s a breakdown of associated costs:
- Filter and Pump Installation: The cost for installing filters and pumps typically falls within the range of $500 to $2,000.
- Relocating Pipes: If there’s a need to relocate pipes to accommodate your pool, you can expect to incur expenses ranging from $360 to $2,000.
- Dedicated Circuit: Establishing a dedicated electrical circuit for your indoor pool can cost anywhere from $600 to $11,000.
- Electrical Subpanel: Installing an electrical subpanel for the pool area may require an investment of approximately $400 to $1,800.
- Bonding and Grounding (Above Ground Pool): For above ground pools, ensuring proper bonding and grounding may entail costs in the range of $200 to $300.
Permits
The cost of obtaining construction permits for your indoor pool construction project can vary significantly, ranging from $200 to $2,000. The specific amount hinges on factors such as whether you’re extending your existing home and incorporating additional features like a patio.
Labor
Labor costs play a significant role in the overall budget for pool installation, typically accounting for 25% to 50% of the total project expenditure. On average, this translates to a cost range of $23,000 to $60,000. The expenses associated with hiring a local inground pool installation company will fluctuate based on several factors, including whether excavation is required, the need for additional plumbing and electrical work, and any customization preferences you may have.
