Some indoor pools are attached to the main living space by a sliding glass door or glass walls. Indoor pools in city apartments or town homes may be located on the basement level. And large residential properties may feature standalone pool houses located adjacent to the main home that may include extras like showers, a spa, or a bar and entertainment area. Whether you dream of converting a room in your home to house an indoor swimming pool, adding an indoor pool extension to your home, or building a dedicated freestanding indoor pool house in your backyard, having an indoor swimming pool means that you can design and decorate it to harmonize with the style of your home. This may mean seamlessly integrating an indoor swimming pool with the rest of your interior design, so that the pool room looks as stylish as any other room in the house. Or it may mean adding contrast by mixing materials, finishes, and styles, or adding a modern pool house on a historic property to complement the marriage between old and new. Check out these indoor swimming pool ideas in a range of sizes and styles to help you plan your own all-weather indoor poolside oasis.
