Types of Indoor Lap Pools

When you think of an indoor lap pool, you might picture a vast, custom-built structure. While those exist, there are several types catering to different needs, spaces, and budgets.

Built-In In-Ground Pools

These are the most traditional and customizable options. They are constructed directly into the ground within an extension of your home or a dedicated pool house. They offer the most seamless integration and a high-end look.

Pros: Fully customizable in size, shape, depth, and materials; high aesthetic appeal; significant value addition to your home.
Cons: Highest cost, longest installation time, requires substantial structural work and space.

Above-Ground Lap Pools

These are more common for outdoor use but can be adapted for indoor settings, especially in homes with sufficient ceiling height and structural support. They are often made from durable materials like steel, aluminum, or composite woods.

Pros: Generally less expensive than in-ground options; quicker installation.
Cons: Can have a less integrated look; requires careful consideration of ceiling height and ventilation; may not be as durable or aesthetically pleasing for an indoor environment.

Swim Spas and Endless Pools

These are compact, self-contained units designed specifically for swimming in place against a current. They are excellent solutions for smaller spaces or when a full-sized lap pool isn’t feasible.

Pros: Space-saving; designed for swimming in place; often include hydrotherapy jets; faster installation; can be more energy-efficient for heating.
Cons: Limited space for actual swimming strokes; less “pool” feel; might be more expensive per square foot than traditional pools.

For the purpose of this guide, we’ll focus primarily on the considerations for a traditional indoor lap pool, whether built-in or adapted above-ground.

Planning Your Indoor Lap Pool Project

Embarking on an indoor lap pool project is a significant undertaking. Careful planning is key to a successful and enjoyable outcome. It involves more than just picking out tiles; it’s about space, structure, and systems.

Space Requirements and Location

This is the first hurdle. You need enough space for the pool itself, plus clearance around it for access, maintenance, and any surrounding features like a deck or seating area. Consider:

Pool Dimensions: Standard lap pools are typically 10-15 feet wide and 30-70 feet long, with a depth of 4-6 feet. Even a shorter length (e.g., 20-30 feet) can be effective for exercise.
Room Size: You’ll need a room significantly larger than the pool itself to accommodate the surrounding area and necessary equipment. A good rule of thumb is to add at least 5-10 feet of clear space on all sides, especially the swimming ends.
Ceiling Height: Crucial for diving, jumping, and avoiding a claustrophobic feel. Aim for a minimum of 8-10 feet, but more is always better, especially if you plan on any acrobatics or simply want an open feel.
Ventilation: Indoor pools produce a lot of moisture. The room needs excellent ventilation to manage humidity, prevent mold, and maintain air quality.
Structural Integrity: A pool filled with water is incredibly heavy (water weighs about 62.4 pounds per cubic foot!). The floor and the house’s structure must be able to support this immense weight. This is a non-negotiable consideration.

Structural Considerations and Permits

This is where professional help becomes essential. An indoor lap pool requires significant structural reinforcement.

Foundation: The existing foundation may need to be strengthened or a new, reinforced concrete slab poured.
Walls and Framing: Support for the pool walls and the house’s overall structure needs careful assessment.
Permitting: Almost certainly, you will need building permits and inspections. Consult your local building department early in the process. Building codes for indoor pools are stringent and cover water, electrical, structural, and ventilation requirements. It’s wise to explore resources like those from the National Park Service on building codes and standards, as they often provide foundational knowledge applicable to various construction projects.

Budgeting for Your Project

Indoor lap pools are a significant investment. Costs can vary wildly based on size, materials, features, and whether it’s a new build or a renovation.

Don’t forget ongoing costs like electricity, water, chemicals, and maintenance.

Key Features and Systems

An indoor lap pool involves several critical systems working together to ensure safe, clean, and comfortable swimming.

Water System: Filtration and Circulation

Clean water is paramount. A robust filtration and circulation system is your first line of defense against contaminants.

Pump: The heart of the system, circulating water through the filter. Variable-speed pumps can save energy.
Filter: Removes debris and impurities. Common types include sand, cartridge, and DE (diatomaceous earth) filters. Regular cleaning and eventual replacement are needed. The EPA provides guidance on water quality, which, while focused on drinking water, highlights general principles of filtration and treatment relevant to maintaining any water body.
Circulation: Ensures water is evenly distributed throughout the pool, preventing stagnant areas where algae can grow and chemicals can become imbalanced.

Water Sanitization

Keeping the water safe to swim in requires effective sanitization.

Chlorine: The most common sanitizer. Can be added manually, via an automatic chlorinator, or through a salt chlorine generator.
Bromine: An alternative to chlorine, often preferred for spas or in situations where chlorine sensitivity is an issue. It’s more stable at higher temperatures.
Ozone Generators: Can supplement traditional sanitizers, reducing the amount of chlorine or bromine needed.
UV Sanitizers: Another supplementary system that uses ultraviolet light to kill microorganisms.

Heating Systems

Maintaining a comfortable water temperature is essential for enjoyable swimming, especially indoors where you control the environment.

Electric Resistance Heaters: Simple and relatively inexpensive to purchase but can be costly to operate due to high electricity consumption.
Heat Pumps: More energy-efficient than resistance heaters, as they transfer heat from the surrounding air. They work best in moderate to warm climates.
Gas Heaters: The fastest way to heat water, but often the most expensive to run depending on gas prices.
Solar Heaters: Can significantly reduce heating costs by using the sun’s energy, but rely on sufficient sunlight and may require a backup system.

Dehumidification and Ventilation

This is perhaps the most CRITICAL system for an indoor pool. Without proper dehumidification and ventilation, you risk serious problems.

Dehumidifiers: Specialized, heavy-duty dehumidifiers are designed for pool environments. They remove moisture from the air, preventing condensation, mold, mildew, and damage to building materials.
Ventilation: Fresh air exchange is vital for air quality and to remove stale, humid air. This often involves an HVAC system designed for indoor pools, which can include air exchangers and specialized ductwork. Consult with HVAC professionals experienced in indoor pool design.

Installation Process: What to Expect

Installing an indoor lap pool is a complex process best handled by experienced professionals. Here’s a general overview of the steps involved:

Planning and Design: This stage involves detailed architectural and structural plans, selecting materials, and choosing all systems (filtration, heating, etc.). You’ll work with architects, pool designers, and structural engineers.
Permitting: The plans are submitted to the local building department for approval. This can take time, so start early.
Site Preparation: This includes excavating (if in-ground), reinforcing the floor, and preparing the space. If it’s an above-ground pool, it involves ensuring the subfloor can handle the weight and installing the pool structure.
Plumbing and Electrical: The intricate network of pipes for filtration and heating, along with the electrical wiring for pumps and lights, is installed.
Pool Shell Installation: For fiberglass or vinyl liner pools, the shell is placed or the liner is installed. For concrete pools, the structure is formed and poured, then given adequate curing time.
Tiling and Finishing: The interior surface of the pool is finished with tiles, plaster, or other suitable materials. Coping and deck surfaces are installed.
Equipment Installation: Pumps, filters, heaters, and dehumidification systems are installed and connected.
Water Filling and Balancing: The pool is filled, and water chemistry is carefully balanced.
System Testing and Commissioning: All systems are turned on, tested, and adjusted to ensure optimal performance.
Final Inspections: The building department conducts final inspections to ensure all work meets code.

The timeline can range from several weeks for a pre-fabricated swim spa installation to six months or even a year for a full custom in-ground pool and enclosure project.

Maintenance: Keeping Your Pool Pristine

Consistent maintenance is key to a healthy, safe, and long-lasting indoor lap pool. While it’s less affected by outdoor debris, indoor pools have unique humidity and air quality considerations.

Water Chemistry

Regular testing and balancing of water chemistry prevent algae, bacteria, and equipment corrosion.

pH: Aim for 7.2-7.6. This affects sanitizer effectiveness and swimmer comfort.
Total Alkalinity: Generally 80-120 ppm. It helps stabilize pH.
Sanitizer Levels: Maintain appropriate chlorine or bromine levels for safety.
Calcium Hardness: Protects pool surfaces from corrosion or scaling.

What to test: Use a good quality test kit (strips or liquid) regularly (daily or weekly for sanitizer/pH, monthly for others).

Cleaning the Pool

Regular cleaning prevents buildup and keeps water clear.

Skimming: Remove any surface debris (though less common indoors).
Brushing: Brush the pool walls and floor weekly to prevent algae growth.
Vacuuming: Vacuum the pool floor as needed, either manually or with an automatic pool cleaner.

Maintaining Equipment

Your pool’s machinery needs care too.

Filter Maintenance: Clean sand filters, empty cartridge filters, or backwash as recommended by the manufacturer.
Pump and Heater Checks: Inspect for any unusual noise or performance issues.
Skimmer and Pump Baskets: Clean these regularly to ensure good water flow.

Managing Humidity and Air Quality

This is where indoor pool maintenance differs significantly from outdoor ones.

Run the Dehumidifier: Ensure your dehumidification system is running as programmed to maintain optimal humidity levels (typically 50-60%).
Ventilation: Ensure pool room ventilation is functioning properly to exchange air and remove moisture.
Air Filter Cleaning: Clean or replace air filters in your HVAC and dehumidification systems regularly, as they can quickly become saturated in a pool environment.

Aesthetics and Comfort

Beyond the functional aspects, creating a pleasant environment is key to enjoying your indoor pool.

Flooring and Decking

Surrounding materials need to be water-resistant, slip-resistant, and durable.

Ceramic or Porcelain Tiles: Excellent durability, water resistance, and a huge variety of styles. Ensure they are rated for wet areas.
Natural Stone: Such as travertine or slate, can offer a luxurious look but require proper sealing and may be more prone to staining.
Concrete (Sealed/Stamped): A durable and customizable option, but can be very slippery if not properly treated.
Treated Wood: Can be used but requires regular sealing and maintenance and may not hold up as well in a high-humidity environment.

Lighting

Proper lighting enhances safety and ambiance.

Underwater Lighting: LED options are energy-efficient and provide beautiful illumination.
Ambient Lighting: Incorporate sconces or ceiling lights for general illumination.
Natural Light: If possible, large windows or skylights can make the space feel more open and airy, but be mindful of potential heat loss or gain and increased humidity.

Temperature Control

It’s not just about the water temperature; the air temperature is important too.
