  • Concrete indoor pool.Precast concrete pools are typically smaller than 8ft by 15ft due to the need to transport and place on site, while custom sizes are cast on site. Several pool shapes and designs are available from this material, as well as different finishes such as paint, aggregate, plaster or special coating. A rectangular pool shape is popular with pre-made models, but they can also be made in circles or squares. Homeowners can expect to pay $20,000 to $50,000 for a precast concrete indoor pool and $29,000 to $90,000 for a custom option, depending on size and customization.
  • Vinyl-Hallenbad.The vinyl coated pools are manufactured on site and are available in various sizes and shapes such as round, lagoon, full-L and rectangular. Vinyl pools require the liner to be replaced every 10 years. Installation prices for a vinyl indoor pool can range from $35,000 to $65,000.
  • Fiberglass indoor pool.Fiberglass pool covers can be installed quickly and come in many designs and styles. Because this pool material needs to be transported, there are limited depths and sizes for this type of indoor pool. They are typically no more than 6 feet deep, no more than 40 feet, and no more than 16 feet wide. Installing this pre-built option can cost anywhere from $45,000 to $85,000.

Larger pools require more labor than smaller pools, and inground pools take longer to install than above-ground options. Depending on the type of installation, pool material and size, labor costs can vary from site to site. Higher living costs in densely populated urban areas lead to a higher employment rate.


Type of dehumidification system

An essential element that should be part of any indoor pool installation project is a dehumidification system. Homes with indoor pools need a system that removes moisture from the air to prevent mold and mildew problems throughout the structure. There are different types of dehumidification systems at different prices. Below are average prices for individual systems for a 12' by 24' pool with an enclosure measuring 22' by 36' or 792 square feet. Whole house dehumidification system prices are based on a 2,500 square foot house.

Type of dehumidification systemAverage installation price
whole house system2.400 US-Dollar bis 8.000 US-Dollar
Ventilation based system4.000 US-Dollar bis 10.000 US-Dollar
mechanical cooling systemUS$ 4.000 bis US$ 20.000
  • Dehumidification system for the whole house.This type of dehumidification system can be installed into the existing HVAC unit to ensure an even decrease in humidity throughout the home. Because these systems are designed for an indoor pool area, they have superior humidity control compared to the average HVAC system or individual dehumidifiers placed in a home. Installing a whole-home dehumidification system can cost anywhere from $2,400 to $8,000.
  • Ventilation based dehumidification system.A ventilation-based system uses outside air to balance the temperature in the bathing area and remove excess moisture in the colder months. A disadvantage of this type of system is that there is no cooling in the indoor pool area during the hot summer months. A cooling coil can be added to the system but has limited dehumidification capabilities. A vent-based system costs between $4,000 and $10,000.
  • Mechanical cooling system.This type of dehumidification system is often the most popular. These systems work by drawing in warm, moist air, extracting the moisture and passing it through cooling coils before releasing the air back into the pool area. Depending on the type and size of the unit, a mechanical cooling system can cost an owner anywhere from $4,000 to $20,000.

Installation of filters and pumps

Pool water filters come in many sizes and shapes, and filters are essential to keeping your pool clean and functioning properly. The average filter andCost of installing a pool pumpranges from $500 to $2,000.

Additional Costs and Considerations

When budgeting for the cost of an indoor pool, homeowners often come across additional pricing factors and considerations. Some factors that can affect the final cost can include the difference between a prefabricated and custom indoor pool, an above ground pool and an inground pool, excavation, installing a heat pump, adjustments, maintenance, property taxes and premiums.

Prefab vs Custom

When a homeowner decides to install an indoor pool, they must choose between a prebuilt option or a custom pool. A prefabricated pool is fabricated off-site and shipped to the installation site as a complete structure, and a custom indoor pool is built on-site. Below are the average prices for prebuilt and custom pool models.

Pool typeinstallation costs
prefab indoor pool$ 20.000 bis $ 85.000
individual indoor pool$ 29.000 bis $ 90.000
  • Prefabricated indoor pool.Prefab indoor pools come in various sizes and shapes such as square, rectangular, L-shaped, kidney-shaped and circular. They lack more extensive customization due to their limited build limitations. Typically constructed from precast concrete or fiberglass, prefabricated indoor pools are more cost-effective than custom options. Building your outdoor pool enclosure will not take as long as building a custom pool on site. Because prefabricated pools require shipping and installation, they must be no longer than 40 feet and no wider than 16 feet. Precast concrete pools are made from concrete slabs that are fabricated off-site and then coated on-site. Prefab indoor pools range in price from $20,000 to $85,000.
  • Custom indoor pool.A custom indoor pool is the shape, size, color, finish, and design that is customized to the owner's personal preferences. Materials, construction equipment and machinery are brought indoors and the pool is built on site rather than being shipped from a factory. Building a pool on site can cause damage to the yard or landscape, and additional landscaping work may be required after the pool is installed. Homeowners should also keep in mind that dust and debris from the construction of an indoor pool can get into the home and lead to extra cleaning. Although,A custom pool can be much more luxuriousthan a prefabricated and custom built indoor pool can cost anywhere from $29,000 to $90,000.

Available in pre-built or custom models, above-ground indoor pools are limited to 48", 52" and 54" deep, but considering they can cost 20% less than an in-ground option, these limitations are worth it for many owners. .
    • Inground Hallenbad.Built-in indoor pools can also be prefabricated or custom built. Due to the wide variety of styles and designs available, it is common for this type of indoor pool to be customized. Installation prices may vary due to labor involved in excavation, site construction, drainage and grading.


    Excavation, site preparation and civil works are required in the area where the indoor pool will be installed. If a structure already exists, the costs are lower than if a structure has to be built for the indoor pool. Average excavation costs range from $4,000 to $10,000 including labor.

    Installation of the heat pump

    Heat pumps keep pool water at a comfortable temperature for year-round swimming. Because electric heat pumps use less energy and are more efficient than resistance heaters, they are the most common type of heat pump for indoor pools. They can heat water between 78 and 86 degrees Fahrenheit and cost between $2,250 and $7,000 to install.


    Additional upgrades or customizations will increase the cost of the indoor pool. Below are some common indoor pool customizations and average installation prices.

    • Automatic pool cover.Automatic pool covers use ratchet gears to open and close the cover over the pool. These handy covers protect against dirt and debris getting into the pool and add extra security when you have pets or children around the house. Installing an automatic pool cover costs between $5,000 and $15,000.
    • pool coverThe pool deck is an area where people can walk or sit around the pool and relax. Prices may vary based on the materials selected, with concrete or a composite material being the most popular. The average cost ranges from $6,750 to $8,000 but can go as high as $26,000 for custom designs or a large platform.
    • pool lighting.Lighting in the pool and around the swimming area can reduce the need for bright overhead lighting. Lighting installation can cost anywhere from $450 to $1,200, with a variety of design and style options available.
    • pool steps.Many prefabricated pool enclosures have steps for easy entry and exit from the water. If steps are required, they can cost anywhere from $1,400 to $1,900.
    • Water games in the pool.Custom water features like waterfalls or fountains provide soothing sounds and add special features to an indoor pool area. They can range from $100 to $3,500.
    • vapor barrier.In order to avoid excessive moisture in the walls, which can lead to mold growth, it is necessary to install a vapor barrier in the walls surrounding the indoor pool. Installation costs for vapor barriers range from $1,200 to $4,000, or $0.50 to $0.75 per square foot.
