An indoor pool is a fantastic luxury, but having one of your own isn’t as out of reach as it used to be. Today’s indoor pools cost between $40,000 and $200,000, with an average cost of $95,000 (compared to $63,715 for typical outdoor in-ground pools).* If you love swimming and hosting pool parties year-round, the cost may be worth it.

The right indoor pool will enhance your home’s value, allow for swimming in all seasons, and let you swim in privacy. Use this guide to learn more about different types of indoor pools, their benefits, and features to consider before purchasing.

Benefits of an Indoor Pool

An outdoor pool can be lovely, but if you live in an area with hot summers, long winters, or close quarters between neighboring homes, an indoor pool could be a better investment. Consider these unique benefits of installing your own indoor pool:

• Health and wellness: Swimming is a low-impact cardio exercise. Incorporating it into your routine more frequently can improve heart health and fitness. Indoor pools improve wellness by letting you keep a routine schedule.
• Potential to increase home value: Unique home features can fetch your home a higher selling price. While it’s not common for pools to get 100% ROI upon resale, boosting your home’s value is an added perk.
• Privacy and convenience: Indoor pools give you more privacy than traditional outdoor pools, which is great if you’re living in an area with small or crowded backyards. Residential indoor pools are also more convenient since you only have to travel to a different area of your house.
• Year-round swimming and recreation: An indoor pool’s main advantage is that seasons and weather won’t interrupt your swimming routines. You can enjoy the pool all winter long, go swimming when it’s raining, and invite guests over even when the temperatures are too high to be outdoors.

Types of Indoor Pools

If you’re imagining your ideal indoor pool, you likely have a specific vision. However, there’s a wide variety of indoor pool options. Each one offers advantages based on your size constraints, preferred swimming pool activities and functionality, and home aesthetic.

Common indoor pool types include the following: 

• Endless pools: Endless pools have adjustable currents that push the water and provide resistance for swimmers. This gives the pool a very small footprint, which can be as small as 8-by-15 feet.
• Hot tubs: Hot tubs are small heated pools meant for relaxing and soaking. They have an average size of 7-by-7 feet or 8-by-8 feet.
• Lap pools: Indoor lap pools are often preferred by serious swimmers and people training for specific lane swimming goals. They consist of a single lane and are between 50 and 75 feet long. This design mimics the feel of a conventional rec center or competitive pool.
• Plunge pools: This pool capitalizes on wellness trends surrounding cold water plunges. Homeowners can fill a very small pool, such as a hot tub, with cold water for plunges after exercises or steam room sessions.

These pool options offer diverse advantages for different lifestyles and fitness goals.

Indoor Pool Designs and Features

You can choose different features and amenities to enhance your pool and surrounding space, as well as the pool itself. We recommend working with an experienced pool designer to create a cohesive, long-lasting, and well-designed space. 

Consider these different aspects.

Lighting

Good lighting is essential for safety. To ensure good visibility around the pool, you can use overhead, underwater, and motion-activated lighting. Additional overhead and accent lighting can improve the ambiance. 

LED lights are a popular, energy-efficient option, and you can easily upgrade it to smart lighting as part of a smart home system.

Heating and Ventilation

Part of the joy of having an indoor pool is that you get to control the environment of the water and the surrounding area. Depending on the type of pool you select, you’ll likely need heating and ventilation systems. 

Indoor pools should also have robust dehumidification systems to prevent mold, mildew, and dampness. We recommend working with an experienced HVAC expert who can properly install and service the system’s units. 

Indoor pool HVAC should include dehumidifiers that don’t evaporate pool water, vent systems to eliminate chemical smells and concentrations, and coolant systems for the air that are separate from the water systems.

Decking and Surrounds

Install your pool in an environment that can handle the moisture and equipment requirements. Detached structures or hybrid indoor-outdoor rooms along the exterior of your home are ideal. You can further prepare the space by installing a concrete floor or covering the foundation with non-porous tile or stone flooring.

To make the pool space more enjoyable for your family and guests (including non-swimmers), consider adding seating, beautiful plants, poolside water features, nearby changing rooms, and a sauna. Smaller investments include inflatable toys, loungers, and floating armbands for helping children learn to swim.

Water Features

Depending on the available space and the primary objective of the pool, you can add aesthetic water features. For a relaxing, spa-like environment, you can add bubblers and fountains. For a resort-like feel for relaxing and hosting guests, consider waterfall features or hot tubs with a wide range of water settings.

Indoor Maintenance

Just like with an outdoor swimming pool, indoor pools require maintenance. However, maintaining a clean pool with balanced, treated water can be easier indoors. Two important aspects of maintenance are keeping the water clean and caring for the equipment.

Cleaning and Water Chemistry

Two main factors impact the clarity and quality of pool water:

1. Chlorine: Chlorine disinfects pool water. Very low traces of chlorine can kill bacteria, but it needs frequent monitoring. 
2. pH: Water should be slightly acidic or neutral. If it’s too caustic (above a pH of approximately 7.6),  it’s basic and alkaline. If it’s below 7, it’s an acidic skin irritant.

To maintain properly chlorinated, neutral water, owners must skim the water and vacuum and brush the sides to remove waste. The water should be frequently tested (and corrected) for imbalances.

Equipment Maintenance

Pools have several pieces of equipment. Pumps and filters circulate the water to automatically skim out large impurities. Heaters condition the water to keep it at preset water temperature controls. Dehumidifiers pull moisture out of the surrounding air to mitigate the risk of mold and mildew. 

Homeowners can conduct routine maintenance and inspections on this equipment, such as checking for error codes, replacing dirty filters, and noticing when the equipment isn’t running as smoothly as it should. Investing in robotic pool cleaners or vacuums and choosing high-quality pool cleaning chemicals can help with these tasks. 

Professional pool technicians should manage the annual servicing, repairs, and modifications because of the technical difficulty and safety hazards of electrical equipment near water.

Another important aspect of owning a pool is pool safety. Teach children and guests about how to safely use and enjoy the pool to minimize risk and maximize family fun.
