Key Considerations for Small Indoor Pool Designs

Before you start picturing yourself doing laps, there are several important factors to consider when planning a small indoor swimming pool. These considerations will help ensure your pool is not only beautiful but also functional, safe, and cost-effective to maintain. Think of these as the essential ingredients for a successful indoor aquatic oasis.

Space and Location

The most crucial aspect is choosing the right space. Will it be in a dedicated room, part of a larger open-plan area, or perhaps a converted sunroom or basement? Measure your potential space carefully. Even a small pool needs enough room for the pool itself, plus some surrounding deck space for entry, exit, and lounging. Consider ceiling height, as this impacts the feeling of spaciousness and can be important for certain pool types like plunge pools or those with diving features (though diving is generally not recommended for small indoor pools). Basements can be excellent, offering insulation and privacy, but require good ventilation. Ground floor additions or sunrooms offer natural light but might require more structural work.

Budget

Indoor pools are a significant investment. Costs include construction, the pool itself (materials, filtration system, heating), ventilation, dehumidification, lighting, and ongoing maintenance (chemicals, electricity, water). Be realistic about your budget and get detailed quotes from pool builders specializing in indoor installations. Remember to factor in potential structural modifications to your home, such as reinforcing floors or creating new wall structures.

Ventilation and Dehumidification

This is perhaps the most critical, yet often overlooked, aspect of indoor pools. The constant evaporation from the water creates high humidity. Without proper ventilation and a robust dehumidification system, this moisture can damage your home’s structure, cause mold and mildew growth, and create an uncomfortable environment. A good ventilation system removes moist air and brings in fresh air, while a dehumidifier actively extracts moisture from the air. Look for systems specifically designed for indoor pool environments. According to the U.S. Environmental Protection Agency (EPA), managing indoor air quality is crucial for health and comfort, and this applies doubly to spaces with large bodies of water like indoor pools.

Heating and Water Quality

Maintaining a comfortable water temperature year-round is essential for an indoor pool. This requires an energy-efficient heating system, such as a heat pump or gas heater. The choice depends on your climate and energy costs. Water quality is also paramount. You’ll need a reliable filtration system and a method for sanitizing the water (e.g., chlorine, bromine, or salt systems). Regular testing and balancing of water chemistry are vital for health and to prevent damage to the pool and its equipment.

Safety Features

Safety is non-negotiable, especially when children or pets are around. Options include pool fencing (even indoors, this can be aesthetically integrated), non-slip surfaces around the pool, depth markers, and securely locking doors to the pool area. Consider the overall depth of the pool, keeping it manageable for its intended use. For a small indoor pool, often a shallower depth is most practical.

The Endless Pools brand is a well-known innovator in this category, offering various models and installation options. You can find more information about their designs on their official website, EndlessPools.com.

3. The Compact Lap Pool (Vertical Style)

If lap swimming is a priority, a more vertical (deep and narrow) lap pool design can work exceptionally well indoors. These aren’t wide, but they are long enough to allow for a few strokes before you turn. This design minimizes the overall width needed, making it feasible for long, narrower spaces often found in basements or converted garages.

Design Elements: Typically rectangular, focused on length, with a depth suitable for swimming.
Ideal Location: Long, narrow rooms, basements, or garages.
Pros: Allows for proper swimming strokes, efficient use of linear space.
Cons: Requires a significant length, can feel less spacious than a wider pool.

4. Integrated Wet Room/Pool Area

For a truly seamless look, consider integrating your small pool into a larger “wet room” concept. This could be an extension of a bathroom, a dedicated spa room, or a covered patio area. The pool itself can be smaller, perhaps a plunge pool or a bench-seated design, surrounded by water-resistant finishes, a sauna, or a steam shower.

Design Elements: Focus on high-quality, waterproof finishes on floors and walls, good drainage, and aesthetic integration with other spa-like features.
Ideal Location: Expansions of bathrooms, dedicated spa rooms, or enclosed sunrooms.
Pros: Creates a cohesive, luxurious spa-like experience, maximizes function in a limited footprint.
Cons: Requires careful waterproofing and drainage planning, can be expensive.

5. The Convertible Pool Concept

A more advanced and often custom-built solution involves a pool that can be partially or fully covered, effectively turning the space into usable room when the pool isn’t in use. This can be achieved with retractable covers or even sub-flooring systems. While these are typically for larger pools, smaller versions are emerging.

Design Elements: Requires sophisticated engineering for safety and water protection when covered. Automated covers are common.
Ideal Location: Versatile, but usually requires significant customisation.
Pros: Maximizes the utility of the space, can be safer when not in use.
Cons: Very high cost, complex engineering, maintenance of the cover system.

Essential Systems for Indoor Pools Explained

Building an indoor pool isn’t just about digging a hole and filling it with water. The magic lies in the supporting systems that keep it running smoothly, safely, and comfortably. For an indoor environment, some of these systems are even more critical than for their outdoor counterparts.

1. Ventilation and Dehumidification Systems

As mentioned, this is crucial. An effective system removes humid air from the pool enclosure and replaces it with fresh, dry air. This prevents condensation, protects your home’s structure, and maintains air quality. Heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) are often used in conjunction with dedicated dehumidifiers to not only manage moisture but also manage energy efficiency by pre-heating incoming air with outgoing air. The ENERGY STAR program offers guidance on selecting efficient dehumidifiers for your home’s needs, which can be adapted for a pool environment for better energy savings.

2. Heating Systems

Indoor pools benefit from consistent temperatures. Common heating methods include:

Electric Heat Pumps: Efficient but can be slower to heat, ideal for moderate climates.
Gas Heaters: Heat water quickly, making them good for rapid heating needs or colder climates, but can be more expensive to run.
Solar Heaters: Can supplement other heating systems, reducing running costs, though less predictable indoors without direct sunlight.

The size of your pool and your local climate will dictate the best heating solution. Proper insulation of the pool and the room itself will significantly reduce heating costs.

3. Filtration and Sanitization

Clean water is healthy water. Every pool needs a robust filtration system to remove debris and particles. Sanitization prevents the growth of bacteria and algae. Common methods include:

Chlorine: A traditional and effective sanitizer, requires careful balancing.
Bromine: Similar to chlorine but often preferred in warmer water and for those sensitive to chlorine.
Saltwater Systems: Use a salt chlorine generator to produce chlorine from salt, leading to softer water and less odor.
Ozone or UV Systems: Can be used as secondary sanitizers alongside chlorine or bromine to reduce chemical usage.

Regular water testing kits are essential for maintaining proper chemical levels and ensuring the water is safe and enjoyable.

Design and Material Choices for Small Indoor Pools

The aesthetic of your indoor pool space is as important as its functionality. Choosing the right materials can enhance the atmosphere, durability, and ease of maintenance.

Pool Shell Materials

The material of the pool itself impacts durability, cost, and appearance:

Fiberglass: Smooth, non-porous surface, quick to install, and low maintenance.
Vinyl Liner: Cost-effective for simple shapes, but liners may need replacement over time.
Concrete (Gunite/Shotcrete): Highly customizable shapes and sizes, durable, but requires a longer construction time and more specialized finishing.
Tile: Can be used as a finish for concrete pools or as accents for other materials, offering a high-end look but can be costly and require grout maintenance.

For small indoor pools, fiberglass and custom concrete with tile finishes are popular for their durability and aesthetic potential. The National Swimming Pool Foundation (now part of the Pool & Hot Tub Alliance) offers guidelines on pool construction standards and materials.

Surrounding Decking and Finishes

The area around your pool needs to be safe, water-resistant, and attractive. Consider:

Non-slip Tiles: Offer excellent traction and are easy to clean. Porcelain or ceramic tiles with textured finishes are good options.
Natural Stone: Like travertine or slate, these provide a luxurious look but require sealing and can be porous.
Waterproof Wood Alternatives: Composite decking materials designed for wet environments can be used.
Epoxy or Resin Coatings: Can be applied to concrete floors for a seamless, durable, and attractive finish.

Ensure all materials are designed to withstand high humidity and potential splashes.

Lighting and Ambiance

Lighting plays a huge role in the mood of your indoor pool area. Consider a combination of:

Underwater LED Lights: Energy-efficient and long-lasting, they create a beautiful glow.
Ambient Room Lighting: Dimmable fixtures that can adjust the mood from bright and energetic to soft and relaxing.
Natural Light: If your space allows for skylights or ample windows, it can make the area feel more open and airy.

Smart lighting systems can allow you to control brightness and color, enhancing the experience.
