Why an Indoor Lap Pool for Home is Gaining Popularity
Having an indoor lap pool at home isn’t just a luxury; for many, it’s a smart investment in health, wellness, and lifestyle. The convenience of having a pool just steps away from your door means you can swim laps whenever you please – early morning, late at night, or during a sudden downpour. It eliminates the need for travel to a gym or public pool, saving you time and hassle. Plus, swimming is a fantastic low-impact exercise that’s great for all ages and fitness levels.
The popularity of indoor lap pools has surged because they offer a consistent, private place for exercise and relaxation. Unlike outdoor pools, they are protected from the elements, meaning no leaves, no snow, and no need to close for the season. This continuous usability makes them a practical choice for serious swimmers, those undergoing physical therapy, or families looking for a healthy activity that everyone can enjoy year-round.
Key Considerations Before You Start
Before you dive into the exciting world of indoor lap pools, there are a few important things to think about. Planning is key to a smooth and successful project. Let’s explore the crucial factors:
1. Space and Location
This is often the first hurdle. How much space do you actually need? For a lap pool, the general rule is a minimum length of 30 feet (about 9 meters) to allow for a decent number of strokes. The width typically ranges from 6 to 8 feet (about 1.8 to 2.4 meters).
- Indoor vs. Outdoor: While this guide focuses on indoor pools, consider if a covered outdoor space or a fully enclosed room within your home is more feasible.
- Structural Support: A significant amount of water weighs a lot. You’ll need to ensure your home’s structure—whether it’s a basement, a ground-floor extension, or a custom-built space—can support the weight of the pool and water. Consulting a structural engineer is highly recommended.
- Ventilation: Indoor pools produce moisture. Excellent ventilation is crucial to prevent humidity issues, mold, and damage to your home. Dehumidification systems are often a necessary component.
- Access and Utilities: Consider easy access for construction and maintenance. You’ll also need access to electricity for pumps and heating, and a water source for filling.
2. Pool Type and Construction
There are several ways to build an indoor lap pool, each with its own pros and cons:
- Inground Concrete Pools: These are custom-built and highly durable. They offer the most flexibility in terms of size and shape but are also the most expensive and time-consuming to construct.
- Vinyl Liner Pools: A pre-formed liner is installed within a frame. These are generally less expensive than concrete but may require liner replacement over time.
- Fiberglass Pools: These are pre-molded shells delivered and installed. They offer a smoother surface and quicker installation than concrete but come in fixed shapes and sizes.
- Endless Pools or Swim Spas: These are a popular and often more space-efficient option for home lap pools. They use a powerful current to allow you to swim in place, requiring less swimming space. Many come as self-contained units that can be easier to install. You can learn more about their innovative system on the Endless Pools website.
3. Budget and Cost Factors
The cost of an indoor lap pool can vary significantly. Here’s a breakdown of what influences the price:
- Size and Depth: Larger and deeper pools require more materials and labor.
- Construction Method: Concrete is typically the most expensive, followed by fiberglass, then vinyl liners. Swim spa units can range from mid-tier to high, depending on features.
- Features: Heating systems, lighting, covers, water treatment systems (like salt chlorinators or UV systems), decking, and enclosure construction all add to the cost.
- Site Preparation: Excavation, structural reinforcement, and plumbing/electrical work are significant expenses.
- Permits and Professional Fees: You’ll likely need permits from your local municipality, and professional fees for designers, engineers, and contractors add up.
A study by the National Association of REALTORS® on home renovations suggests that while pools can add enjoyment, their impact on resale value can be variable and depend heavily on the market and how well the pool integrates with the property. For a rough estimate, an inground lap pool can range from $30,000 to $100,000+, depending heavily on customisation and your location. Self-contained swim spa units typically start in the $15,000 to $30,000 range, plus installation costs.
Step-by-Step Guide to Installing Your Indoor Lap Pool
Installing an indoor lap pool is a project best suited for professionals, but understanding the process will help you communicate effectively with contractors and make informed decisions.
Step 1: Design and Planning
This is where you finalize your vision. Work with a pool designer or builder to determine:
- Exact dimensions and shape.
- Pool material (concrete, fiberglass, shell, swim spa).
- Location within your home or extension.
- Water heating and filtration system requirements.
- Ventilation and dehumidification needs.
- Safety features (fencing, covers, alarms).
- Aesthetics (tile, surrounding deck, lighting).
Step 2: Permits and Approvals
Your pool builder will handle most of this, but you’ll need to be aware of your local building codes. This involves submitting detailed plans to your local municipality for approval. This step ensures safety standards are met and the structure is sound.
Step 3: Site Preparation and Excavation
If you’re building an inground pool, this involves digging the hole for the pool. For above-ground options or swim spas, it might involve preparing a level, reinforced concrete pad. Structural engineers will be key here to ensure your subfloor or existing structure can handle the immense weight.
Step 4: Pool Construction or Installation
- Inground Pools: This is the most complex stage, involving rebar reinforcement, concrete pouring (for concrete pools), or setting the fiberglass shell.
- Vinyl Liner Pools: The frame is erected, and the liner is carefully fitted and filled to prevent wrinkles.
- Swim Spas/Endless Pools: These units are typically delivered and placed in their designated spot, requiring connections for water and power.
Step 5: Plumbing and Electrical Work
This is critical for the pool’s function. It includes connecting the:
- Filtration system (pump, filter).
- Heating system (gas heater, heat pump, or electric heater).
- Sanitization system (chlorinator, salt system, UV sanitizer).
- Any lighting or water features.
Proper electrical grounding and safety measures are paramount, especially in a wet environment. For guidance on electrical safety in damp locations, the National Fire Protection Association (NFPA) provides comprehensive safety standards.
Step 6: Decking and Enclosure
The area around your pool needs to be finished. This could involve tiling, stone, or other waterproof materials for the deck. If the pool is in a new room, this stage involves completing the room construction, including walls, ceiling, and ventilation.
Step 7: Filling and Water Treatment
Once construction is complete, the pool is filled with water. Then, the water chemistry needs to be balanced using chemicals like chlorine, bromine, pH adjusters, and alkalinity increasers. Your builder or a pool professional will guide you through this initial balancing.
Step 8: Ventilation and Dehumidification System Installation
This is unique to indoor pools. A robust HVAC system designed for high humidity is essential. This system will remove moisture from the air, preventing condensation on walls and ceilings and protecting the overall structure of your home. Commercial-grade dehumidifiers designed for natatoriums (indoor pool areas) are often used. Companies like PoolPak specialize in these climate-control systems.
Essential Features for Your Indoor Lap Pool
To make your indoor lap pool experience safe, comfortable, and enjoyable, consider these essential features:
