How Much Does an Indoor Pool Cost?

An indoor pool can be an attractive addition to any home. But how much does an indoor pool cost, exactly? The costs can vary greatly depending on multiple factors, ranging from $20,000 to over $500,000.

This article explains the types of pools and their cost factors to help you get a better idea of how to finance the cost of building an indoor pool.

Highlights/Key Takeaways

• Indoor pool installation costs differ according to the size, shape, and type of pool installed. For example, saltwater pools may cost more than regular pools.
• Outside of installation costs, you should consider cleaning and maintenance expenses as well, as pools need to be maintained on a bi-monthly or monthly basis.
• You should also consider accessories and other costs, like permits, insurance, or energy-efficiency systems.

Indoor Pool Cost by Type

Common types of swimming pools include:

• Concrete
• Vinyl
• Fiberglass

The cost of indoor pool construction varies depending on the type of pool you want to build.

Concrete Indoor Pools

Concrete is one of the most common indoor pool materials. Concrete pools are a popular choice because they offer a lot of flexibility with regard to shape and design.

Concrete pools can cost anywhere from $29,000 to $60,000, though they can run for upward of $100,000, depending on their size.

Fiberglass Indoor Pools

Fiberglass pools are much easier to install than concrete pools. Some fiberglass pools have pre-made options that can be put in place in a few short days.

Fiberglass tends to be more affordable than concrete, though it can still cost upwards of $60,000.

Vinyl Indoor Pools

One of the more affordable options for an indoor pool is a vinyl pool, which typically costs $20,000–$50,000 to install. Vinyl pools take a bit longer to install than fiberglass, but not as long as concrete. The average installation time for an indoor vinyl pool is two to four weeks.

Above-Ground Pools

Above-ground indoor pools are not only some of the most affordable options but also some of the easiest pools to install. Above-ground indoor pools can be up and running within about three days and usually cost around $10,000–$20,0000.

Cocktail Pools

A cocktail pool is a shallow, small indoor pool. Cocktail pools aren’t designed for sports or games but for kicking back, relaxing, and socializing. On average, they cost $20,000–$40,000 to install.

Endless Pools

An endless pool is a fun and unique type of pool that generates a propulsive current so you can swim without actually moving (think of it as an aquatic treadmill). These pools are particularly useful for:

• Swimming
• Water aerobics
• Aqua jogging

These pools are customizable and tend to be rather expensive, usually starting around $30,000 to install and going up from there.

Hot Tubs

Hot tubs are accessible, relatively inexpensive indoor pools for socializing, relaxation, and hydrotherapy. Hot tubs average $5,000–$15,000.

Indoor Pool Cost by Size

The type of pool you install dictates the cost, as does the indoor pool size.

Some of the common pool sizes include:

• 8’ x 15’
• 10’ x 16’
• 10’ x 20’
• 10’ x 30’
• 12’ x 16’
• 12’ x 20’
• 12’ x 24’

These sizes also depend on the shape of the pool. Indoor pools can cost anywhere from $50 to $125 per square foot.

Small pools are pools less than 200 square feet. These pools range from $20,000 to $50,000, depending on the type of pool. Medium pools, which are between 200 and 500 square feet, cost an average of $50,000–$100,000. Large pools are pools greater than 500 square feet. They can cost upwards of $100,000–$250,000.

Indoor Pool Maintenance and Running Cost

The costs of an indoor pool don’t stop at installation. Once the pool is installed, you have to consider how much it costs to maintain it and keep it running, which requires services like water treatment, cleaning, and dehumidifying.

These are all important costs to keep in mind when you're considering installing an indoor pool.

Dehumidification System

A dehumidification system is a critical part of having an indoor pool. Without a proper dehumidification system, there will be high humidity levels in the pool room, which can lead to damage and the growth of mold and bacteria.

These systems vary widely in cost. Smaller units can cost a few thousand, while industrial-sized units can go for more than $50,000.

Heating System

If you want the added luxury of a heated pool, you must also consider the cost of a heating system. The average pool heating system costs around $3,000, though it may be less or more depending on the size of your pool.

Lighting

If you want to use your pool at night, you’ll need to install pool lighting. Low-cost lighting systems are as little as $20 (but are very limited), while high-cost systems can be $1,700. On average, pool lights tend to cost $625.

Pool Covers

Pool covers are a wise investment for indoor pool owners. They help you save money on your energy and water bills because they reduce water evaporation and heat loss.

Pool covers tend to be one of the less expensive accessories, with basic products only costing around $70. If you have a custom-shaped or particularly large pool, however, you’ll likely pay more.

Water Treatment

Water treatment is a critical part of keeping pool water clean. It involves the removal of dirt, bacteria, and other contaminants to prevent harmful microorganisms from breeding and growing.

You should have your pool water treated every month. Depending on the size of the pool, this service can cost anywhere from $50 to $200 per treatment.

Maintenance and Cleaning

Keeping your pool clean and sparkling is another important responsibility to consider. Depending on how often you get your pool cleaned and what’s included with the service, you may pay between $30 and $150 per month.

Indoor Pool Costs by Design and Shape

Design and shape are two additional factors affecting total pool cost. Consider these popular shapes:

• Rectangular pools: This is the most common shape for indoor pools. They might cost between $20,000 and $100,000, depending on the size and materials used.
• Round pools: These offer a classic look but can be more expensive than rectangular pools, costing somewhere in the neighborhood of $30,000–$120,000.
• Kidney-shaped pools: These unique pools provide enhanced aesthetic value to your indoor pool space, making them more expensive. They can cost $40,000–$150,000.
• Figure-8 pools: Figure-8 pools have an offbeat visual appeal similar to kidney-shaped pools. They can cost anywhere from $50,000 to $200,000.
• Multi-sided pools: These variable-shaped pools tend to be on the pricier side, costing an average of $60,000–$250,000.
• Custom-shaped pools: Custom-shaped pools are the most expensive since they’re designed to be totally unique. They can cost as much as $500,000.
• L-shaped pools: This is a common pool type that offers dual functionality for both swimming and socializing. These pools run between $50,000 and $200,000.
• Roman pools: Roman pools feature a classic design that harkens back to classical Western architecture. They can cost $50,000–$200,000.

It’s hard to give a definitive price point for indoor pools, even when they’re the same shape, as pool cost is partially dictated by the size of the pool and what material the pool is made from.

Additional Indoor Pool Costs

In addition to building and maintaining your indoor pool, you’ll also need to consider additional costs, such as:

• Permits: $25 to $3,000. Some local governments require permits before you can construct a new indoor pool. Depending on your location, permits may cost up to $3,000.
• Insurance: $115/month. You should also purchase insurance when you build an indoor pool, which can help protect you and your property if there’s a pool-related accident. Insurance costs depend on the pool’s size, location, and other factors, but the average is $1,383 a year.
• Energy Efficiency: $2,500 to $4,000. Investing in energy efficiency is also worth the upfront expense because it can save you considerable money on water and electric bills in the future.
• Pool Accessories: $10,000. You may want to incorporate diving boards, pool slides, or some poolside furniture.
• Additional Ventilation: $2,400 to $20,000. You may want to install additional ventilation systems in your pool room to prevent mold and mildew growth.

Indoor Pool Financing Options

It should be clear by now that indoor pool prices are no small investment. Here are some financing options that can help install the pool of your dreams:

• Home equity loans: A type of loan where you use your home as collateral.
• Personal loans: These offer more flexibility, allowing you to compare pool loan rates and lenders. Some of the best pool loan providers include Upgrade, Best Egg, Discover, and OneMain Financial.
• Financing through a pool contractor: You can often work directly with the pool contracting company to discuss financing and payment plans.

If taking out a loan isn’t a feasible option, you can discuss financing directly through the pool contractor you want to work with.

How to Save Money on Indoor Pool Costs

By implementing these money-saving tips, you can get an indoor pool without paying an arm and a leg.

• Do Your Research: Learn more about different pool types before moving forward with a decision. Consider the space of your pool room, how the pool will be used, and what the maintenance costs are for each type of indoor pool.
• Look for Discounts: Some suppliers and pool builders offer deals or discounts for new clients.
• Be Energy-Efficient: Being more energy-efficient isn’t just the latest trend. It’s also a valuable way to save money long-term on energy bills.
• Smaller Pools: Smaller pools cost less than larger pools. Opting for a smaller pool can help you save on indoor pool construction costs.
• Financing: Seeking financing via a pool loan can help you spread out the cost of building the pool over time.
• Know the Legal Requirements: Before you make up your mind to put in an indoor pool, find out whether there are any potential permits or legal requirements enforced in your area so you can factor in those costs.
• Get Smart Accessories: Self-regulating smart accessories, such as pool covers, energy-efficient lighting, and pool automation systems, can also save you money over the long term.
• Work with a Pool Designer: A pool designer can help you come up with a detailed design for your indoor pool and provide a cost estimate to help you plan better.

Final Word

Indoor pools cost thousands of dollars to install, depending on the size, shape, design, and type of pool. Beyond installation, there are also cleaning, maintenance, and repair costs to think about.

If you’re in the market for an indoor pool, carefully consider any and all potential costs and find a smart financing plan to help you build the pool of your dreams.
