Hello, my friend, hello again; today we come together to talk about How Much Does an Indoor Pool Cost? and hope the blog can help you.
Investing in an indoor pool means the therapeutic benefits of swimming can be enjoyed year-round. Indoor pool cost ranges from $40,000 to $200,000, with the national average at $95,000.
- Typical Range: $40,000 to $200,000
- National Average: $95,000
Installing an indoor pool is an excellent option for many homeowners who want to enjoy the therapeutic benefits of swimming year-round. For those who live in colder climates, an indoor heated pool is a great way to exercise and relax without the hassle of closing up the pool after a few short months of warm weather. An indoor house pool can be installed in a basement, screened-in porch, sunroom, or inside a structure that is built specifically for a residential indoor pool. How much does an indoor pool cost? The average cost of indoor pool installation ranges from $40,000 to $200,000, with many homeowners spending approximately $95,000 for a 40-inch deep, 12-foot by 24-foot fiberglass pool with concrete decking inside an existing structure. An indoor above-ground pool that measures 12 feet by 24 feet that’s added to an existing space can cost $10,000 to build, while the price to build an indoor lap pool and a new structure to house it in can run upwards of $350,000.
The minimized maintenance, reduced chemical use, and year-round swimming outweigh the installation costs for many homeowners. Some important factors that influence indoor pool cost are installation method; pool size, type, material, and shape; dehumidification system costs; and permit fees. Local labor costs can vary, but it’s common for an inground indoor pool to cost considerably more in labor than an above-ground indoor pool. This is due to the extra time and effort that is needed to break through a home’s foundation for installation. This guide will examine the factors that affect indoor pool cost, the types of indoor pools, indoor pool designs, the benefits of having an indoor pool, and the important questions to ask a professional before deciding on such a big purchase.

Factors in Calculating Indoor Pool Cost
How much is an indoor pool? That depends on several factors. Indoor pool installation price can vary based on pool size, material, type, and shape; local labor prices; dehumidification system type; filter and pump installation; and permit fees.
Pool Size
The cost to build an indoor pool depends on the size and whether the pool is prefabricated or custom made. For those looking for a tiny, small indoor pool, the smallest option is usually 8 feet by 15 feet, or 120 square feet. Prefabricated indoor pools cost from $69.50 to $295 per square foot, and custom models run from $100.50 to $312.50 per square foot. A 12-foot by 24-foot indoor pool is the most common size, but there are smaller and larger options available. Below are installation price ranges for prefabricated and custom indoor pools based on size.
| Pool Size | Prefab Cost | Custom Cost |
| 8 feet by 15 feet (120 square feet) | $8,350 to $35,400 | $12,060 to $37,500 |
| 12 feet by 16 feet (192 square feet) | $13,350 to $56,640 | $19,296 to $60,000 |
| 12 feet by 20 feet (240 square feet) | $16,680 to $70,800 | $24,120 to $75,000 |
| 12 feet by 24 feet (288 square feet) | $20,000 to $84,960 | $28,944 to $90,000 |
| 15 feet by 20 feet (300 square feet) | $20,850 to $88,500 | $30,150 to $93,750 |
| 14 feet by 28 feet (392 square feet) | $27,250 to $115,640 | $39,396 to $122,500 |
| 16 feet by 32 feet (512 square feet) | $35,550 to $151,040 | $51,456 to $160,000 |
| 16 feet by 36 feet (576 square feet) | $40,000 to $169,920 | $57,888 to $180,000 |
| 20 feet by 40 feet (800 square feet) | $55,600 to $236,000 | $80,400 to $250,000 |
| 20 feet by 60 feet (1,200 square feet) | $83,400 to $354,000 | $120,600 to $375,000 |
| 30 feet by 50 feet (1,500 square feet) | $104,250 to $442,500 | $150,750 to $468,750 |
Pool Material
The pool material influences the overall installation price. The most common materials are vinyl, fiberglass, and concrete. Vinyl is used for custom indoor pools, fiberglass is used for prefabricated options, and concrete can be used for both. Below are price ranges for both prefab and custom indoor pools based on the construction material and not including the cost of separate items, such as a dehumidifier, heater, or enclosure.
| Pool Material | Prefab Cost | Custom Cost |
| Concrete | $20,000 to $50,000 | $29,000 to $90,000 |
| Vinyl | N/A | $35,000 to $65,000 |
| Fiberglass | $45,000 to $85,000 | N/A |
- Concrete indoor pool. Precast concrete pools are typically less than 8 feet by 15 feet in size since they need to be shipped and craned into place, while custom sizes are poured on-site. There are various pool shapes and designs available in this material, as well as various finishes, such as paint, aggregate, plaster, or a specialty coating. A rectangular pool shape is popular for precast models, but they can also be made in circles or squares. Homeowners can expect to pay between $20,000 and $50,000 for a prefabricated concrete indoor pool and between $29,000 to $90,000 for a custom option, depending on size and customizations.
- Vinyl indoor pool. Vinyl indoor pools are made on-site and are available in various sizes and shapes, such as round, lagoon, full-L, and rectangular. Vinyl pools need liner replacements approximately every 10 years. Installation prices can range from $35,000 to $65,000 for an indoor vinyl pool.
- Fiberglass indoor pool. Fiberglass indoor pool shells can be installed quickly and are available in many designs and styles. Since this pool material needs to be shipped, there are limited depths and sizes for this type of indoor pool. They are typically no deeper than 6 feet, no longer than 40 feet, and no wider than 16 feet. This prefab option can cost from $45,000 to $85,000 to install.
Pool Type
Based on preference and location, indoor pools can be above-ground or inground. The pricing of indoor pools varies due to installation type and project scope. Inground models require excavation and have the ability to be more customized than an above-ground option. Each type of pool is discussed in a section below.

Pool Shape
While many people envision a rectangular shape for an indoor pool, there are many design types available. Below are some popular indoor pool shapes and the prices for an inground option, including labor.
| Indoor Pool Shape | Prefab Cost | Custom Cost |
| Kidney | $20,000 to $35,000 | $30,000 to $65,000 |
| Rectangular | $20,000 to $60,000 | $60,000 to $70,000 |
| Classic | $25,000 to $45,000 | $29,000 to $90,000 |
| Lagoon | $35,000 to $75,000 | $70,000 to $100,000 |
- Kidney-shaped indoor pools. Kidney-shaped indoor pools are available in various sizes and are an excellent option for homeowners who are looking for a visually appealing shape. This indoor pool shape runs from $20,000 to $35,000 for a prefab model and from $30,000 to $65,000 for a custom pool.
- Rectangular indoor pools. This standard pool shape comes in many sizes and can be installed in numerous different enclosures. These are popular with many homeowners due to their price range of $20,000 to $60,000 for a prefab pool and $60,000 to $70,000 for a custom model.
- Classic indoor pools. The classic pool shape is a rectangle with detailed accent curves. The classic Roman design includes half-circles at each end with rounded corners, while Grecian designs have less-structured angles and curves for a flowing layout. These stylish indoor pools can cost from $25,000 to $45,000 for a prefab option and between $29,000 and $90,000 for a custom classic pool.
- Lagoon indoor pools. For those who want an indoor pool to look like a natural body of water, the lagoon shape is the best option. This design allows for extensive customizations with rocks, waterfalls, and grottos for the area to resemble a tropical oasis. Homeowners can expect to pay between $35,000 and $75,000 for a prefab design and from $70,000 to $100,000 for a custom lagoon pool.
Labor
Larger pools require more labor than smaller pools, and inground pools will take more time to install than above-ground options. Depending on installation type, pool material, and size, the price of labor can fluctuate from location to location. A higher cost of living in densely populated urban areas will result in a more expensive labor rate.
Dehumidification System Type
One essential item that needs to be a part of an indoor pool installation project is a dehumidification system. Homes with indoor pools need a system that draws the moisture out of the air to avoid mold and mildew issues throughout the structure. There are different types of dehumidification systems at various price points. Below are the average prices of the individual systems for a 12-foot by 24-foot pool with an enclosed space that measures 22 feet by 36 feet, or 792 square feet. The whole-home dehumidification system price is based on a 2,500-square- foot home.
| Dehumidification System Type | Average Installation Price |
| Whole-home system | $2,400 to $8,000 |
| Ventilation-based system | $4,000 to $10,000 |
| Mechanical refrigeration system | $4,000 to $20,000 |
- Whole-home dehumidification system. This type of dehumidification system can be installed in the existing HVAC unit to ensure an even decrease in humidity throughout a home. Since these systems are designed with an indoor pool area in mind, they have superior humidity control compared to an average HVAC system or individual dehumidifiers placed throughout a home. An indoor whole-home dehumidification system can cost between $2,400 and $8,000 to install.
- Ventilation-based dehumidification system. A ventilation-based system utilizes the outside air to balance the internal temperature of the swimming area to eliminate excess humidity during the colder months. One downside about this type of system is that during the warm summer months, there is no cooling to the indoor pool area. A cooling coil can be added to the system, but it has limited dehumidification properties. A ventilation-based system costs from $4,000 to $10,000.
- Mechanical refrigeration system. This type of dehumidification system is typically the most popular. These systems work by pulling in the humid warm air, drawing out the moisture, and passing it over cooling coils before the air is released back into the pool area. Depending on the type of unit and the size, a mechanical refrigeration system can set a homeowner back between $4,000 and $20,000.
Filter and Pump Installation
Pool water filters are available in many sizes and shapes, and filters are important to keep the pool clean and working properly. The average filter and pool pump installation cost ranges from $500 to $2,000.
Permits
Indoor pool installations typically require a building permit. Many professional pool installation companies will know the local requirements and will acquire the necessary permits, but it’s always helpful for homeowners to check with their local city regulations to budget for permit fees.
Additional Costs and Considerations
When budgeting for indoor pool cost, homeowners will often come across additional price factors and considerations. Some factors that can impact the final cost can include the difference between a prefabricated and a custom indoor pool, above-ground versus an inground pool, excavation, heat pump installation, customizations, maintenance, property taxes, and homeowners insurance premiums.
Prefabricated vs. Custom Indoor Pool
When a homeowner decides to install an indoor pool, they must choose between a prefabricated option or a custom-made pool. A prefab pool is made off-site and transported to the installation location as a complete shell, and a custom indoor pool is constructed on-site. Below are price averages for prefab and custom pool models.
| Pool Type | Installation Cost |
| Prefabricated indoor pool | $20,000 to $85,000 |
| Custom-made indoor pool | $29,000 to $90,000 |
- Prefabricated indoor pool. Prefabricated indoor pools can come in various sizes and shapes, such as square, rectangular, L-shaped, kidney, and circle. They do lack more extensive customizations because of their limited construction restraints. Usually made of precast concrete or fiberglass, prefab indoor pools are less expensive than custom options. It doesn’t take as long to construct the pool shell off-site as it does to make a custom pool at the installation space. Since prefab pools need to be transported and craned into place, they cannot be longer than 40 feet or wider than 16 feet. Concrete prefab pools are made of concrete panels that are made off-site and then aligned on-site. Prefab indoor swimming pools range in price from $20,000 to $85,000.
- Custom-made indoor pool. For a custom-made indoor pool, the shape, size, color, finish, and design are made according to the homeowner’s personal vision. The materials, construction equipment, and machinery are brought to the house, and the pool is built on-site rather than transported from a factory. Building a pool on-site can result in a damaged yard or landscaping, and additional landscaping services may be needed after the pool installation. Homeowners will also want to consider that the construction dust and debris that results from building an indoor pool can permeate into the home and result in extra cleaning. However, a custom pool can be much more luxurious than a prefabricated one, and a custom-made indoor swimming pool can cost from $29,000 to $90,000.
Above-Ground vs. Inground
Based on construction type, the installation price for an indoor pool can vary considerably. Below are the average price ranges for both above-ground and inground indoor pools.
| Pool Construction Type | Installation Price with Labor |
| Above-ground | $10,000 to $36,000 |
| Inground | $40,000 to $200,000 |
- Above-ground indoor pool. Homeowners who are interested in saving money on indoor pool installation costs typically choose an above-ground pool for their space. Available as prefab or custom-made models, above-ground indoor pools are limited to 48 inches, 52 inches, and 54 inches in depth, but considering they can cost 20 percent less than an inground option, these limitations are worth it to many homeowners.
- Inground indoor pool. Inground indoor pools can also be prefab or custom made. It’s common for this type of indoor pool to be custom due to the wide variety of available styles and designs. Installation pricing can vary because of labor involved for excavation, on-site construction, drainage, and leveling services.
Excavation
Excavation, site prep, and construction will need to be done on the area where the indoor pool will be installed. If there is a structure already in place, the costs will be lower than if a structure needs to be constructed to house the indoor pool. The average cost for excavation runs from $4,000 to $10,000, including labor.
Heat Pump Installation
Heat pumps keep the pool water at a comfortable temperature for year-round swimming activities. Since electric heat pumps use less energy and are more efficient than resistance heaters, they’re the most common type of indoor pool heat pump. They can heat the water between to 78 and 86 degrees Fahrenheit, and they cost between $2,250 and $7,000 to install.
Customizations
Additional enhancements or customizations will drive up indoor pool cost. Below are some common indoor pool customizations and the average installation prices.
- Automatic pool cover. Automatic pool covers use interlocking gears to open and close the cover over the pool. These convenient covers protect against debris and dirt getting into the pool and add peace of mind if there are pets or children in the home. An automatic pool cover costs from $5,000 and $15,000 to install.
- Pool deck. A pool deck is a space where people can walk around the pool or sit and relax. The pricing can vary due to the selected materials, with concrete or a composite material being the most popular. The average cost runs between $6,750 to $8,000, but it can cost as much as $26,000 for custom designs or a large deck.
- Pool lighting. Lighting in the pool and around the swimming area can decrease the need for harsh overhead lighting. Lighting installation can cost from $450 to $1,200, with a multitude of design and style options available.
- Pool steps. Many prefabricated pool shells include steps for easy access in and out of the water. If steps are needed, they can cost between $1,400 and $1,900.
- Pool water features. Custom water features, such as waterfalls or fountains, provide relaxing sounds and add specialized features to an indoor pool space. They can range in cost from $100 to $3,500.
- Vapor barrier. To prevent excess moisture on the walls that can lead to mold and mildew growth, a vapor barrier needs to be installed on the walls surrounding the indoor pool. Vapor barrier installation cost ranges from $1,200 to $4,000, or $0.50 to $0.75 per square foot.
