Small Underground Pool Ideas for Modern Backyards

Small underground pools are gaining popularity as homeowners seek to maximize their outdoor spaces without compromising on luxury or style. These compact aquatic features offer a refreshing retreat while complementing modern landscape designs. This article explores creative ideas for small underground pools, their feasibility in various backyard sizes, and techniques to enhance their visual appeal.

Small Underground Pool Ideas for Modern Backyards

Can a small underground pool fit in any backyard?

The feasibility of installing a small underground pool depends on several factors, including the size and layout of your backyard, local zoning regulations, and soil conditions. While many properties can accommodate a compact pool, it’s essential to consider:

  1. Minimum space requirements: Most small underground pools require at least 150-200 square feet of space, including the pool area and surrounding deck or patio.

  2. Setback regulations: Local building codes often dictate minimum distances between pools and property lines, structures, and utilities.

  3. Access for construction: Ensure there’s sufficient space for excavation equipment to enter your property and maneuver during installation.

  4. Soil stability: A geotechnical survey may be necessary to determine if your soil can support an underground pool structure.

  5. Existing landscaping: Consider how the pool will impact established trees, gardens, or hardscaping elements.

While not every backyard can accommodate an underground pool, many homeowners find creative solutions to integrate these features into their outdoor spaces.

Modern backyards benefit from sleek, minimalist pool designs that complement contemporary architecture and landscaping. Consider these innovative ideas for small underground pools:

  1. Infinity edge pools: Create the illusion of endless water by incorporating an infinity edge, even in compact spaces.

  2. Plunge pools: These deep, narrow pools are perfect for cooling off and add a touch of luxury to small yards.

  3. Cocktail pools: Combine a small pool with built-in seating areas for a versatile entertainment space.

  4. Lap pools: Elongated, narrow designs maximize swimming space in limited areas.

  5. Geometric shapes: Angular pool designs, such as rectangles or L-shapes, align well with modern architectural styles.

  6. Glass-walled pools: Transparent walls offer a striking visual element and can make the pool appear larger.

  7. Tiled mosaics: Incorporate intricate tile patterns to add visual interest to the pool floor or walls.

  8. Integrated water features: Incorporate waterfalls, fountains, or bubblers to enhance the sensory experience.

By tailoring these ideas to your specific backyard dimensions and personal preferences, you can create a stunning focal point that elevates your outdoor living space.

How to make a small underground pool look bigger

While compact in size, small underground pools can be designed to appear more spacious through clever visual tricks and landscaping techniques. Consider these strategies to enhance the perceived size of your pool:

  1. Use light-colored materials: Opt for pale pool finishes and surrounding decking to reflect light and create an illusion of depth.

  2. Incorporate reflective surfaces: Install mirrored elements or polished metal accents around the pool area to amplify the sense of space.

  3. Implement strategic lighting: Underwater LED lights and well-placed landscape lighting can make the pool area feel larger at night.

  4. Create visual continuity: Use similar materials for the pool surround and adjacent patio areas to blur boundaries.

  5. Add vertical elements: Tall plants, water features, or sculpture can draw the eye upward, making the space feel more expansive.

  6. Minimize clutter: Keep pool equipment hidden and maintain a clean, uncluttered pool deck to maximize visual space.

  7. Incorporate infinity edges: Even in small pools, an infinity edge can create the illusion of a larger body of water.

  8. Use glass fencing: If safety barriers are required, opt for transparent glass panels to maintain open sightlines.

  9. Implement a vanishing edge: Design one side of the pool to blend seamlessly with the surrounding landscape or view.

  10. Integrate the pool with indoor spaces: For homes with suitable layouts, create a visual connection between interior living areas and the pool to extend the perceived space.

By employing these techniques, homeowners can maximize the impact of their small underground pools and create a more expansive outdoor oasis.


Small underground pools offer a practical and stylish solution for modern backyards with limited space. By carefully considering your property’s constraints, exploring creative design ideas, and implementing visual enhancement techniques, you can transform even the most compact outdoor area into a luxurious aquatic retreat. Whether you opt for a sleek plunge pool or a multifunctional cocktail pool, these compact water features prove that size doesn’t have to limit the impact of your backyard oasis.
