If you’re a dedicated swimmer but tired of crowded lanes or expensive gym memberships, the idea of having a lap pool at home may sound perfect. After all, who wouldn’t want to swim whenever they feel like it — without leaving the house? But before you jump into a costly, time-consuming project, you might want to reconsider. A traditional lap pool requires a significant investment, not just in terms of money but also time and effort. Permits, construction, landscaping … it all adds up.
Offering the benefits of an in-ground pool without all the hassle of excavation, a swim spa is perfect for swimmers who want an efficient, versatile, and year-round solution for lap swimming. Unlike a traditional lap pool, a swim spa can be used by the whole family for fun, relaxation, and exercise — and it can fit in smaller backyards with ease.
Before you commit to a traditional lap pool, let’s compare what each option offers.
What is a lap pool?
A lap pool is a long, narrow pool designed specifically for swimming laps. These pools are typically built for fitness and training purposes, providing a dedicated space for swimmers to get a full-body workout in a controlled environment.
Lap pools can vary in size, but they are usually at least 4 feet wide and can be much longer than a typical backyard pool to accommodate the continuous strokes of lap swimming. They can also be customized to suit specific needs, whether for fitness, relaxation, or both. There are several types of lap pools:
Traditional lap pools
Traditional lap pools are long, narrow pools built specifically for swimming laps. They often range from 40 to 70 feet in length and are designed to provide a dedicated space for uninterrupted swimming. Traditional lap pools are great for fitness-focused individuals with large backyards or access to public swimming facilities.
Swim in place pools
A swim-in-place pool is a compact pool option designed for smaller spaces. These pools allow swimmers to swim in place by using a current that simulates lap swimming. Swim-in-place pools are perfect for those who want the experience of swimming laps but don’t have the space for a traditional, long pool. These pools are usually equipped with a powerful current system that creates a resistance stream, making them ideal for swimmers who want a low-impact workout in a small area.
Swim machine pools
A swim machine pool uses a separate piece of equipment that is added to an existing in-ground pool to generate a current for swimming. The swim machine typically features a mechanical or hydraulic system that creates a consistent, adjustable flow of water, allowing swimmers to swim in place while experiencing a more natural and open-water-like environment.
Lap pool vs swim spa: How do they compare
Both lap pools and swim spas are great options for swimming at home. However, they differ in size, installation, cost, and versatility. Understanding the key differences can help you decide which option is the better fit for your backyard and lifestyle.
Space requirements
Lap Pool: A traditional lap pool requires a significant amount of space. Not only do you need enough room for the pool itself, but you’ll also need additional clearance for safety, maintenance, and deck space. Expect the pool to require 10 extra feet in length and 6 extra feet in width just for clearance. Add in extra patio or decking options, and the space quickly adds up, making it a less viable option for small backyards.
Swim Spa: One of the key advantages of a Michael Phelps Swim Spa is that it requires less space. Michael Phelps models are 8 feet wide and less than 20 feet in length. You only need to budget around 3 feet of clearance on all sides of the spa. Plus, the self-contained unit makes installation easier and quicker. Once your site is ready, it takes less than a day to install. For more details, download our Backyard Planning Guide.
Year-round use
Lap Pool: In most areas, a traditional pool can only be used for part of the year because of weather. While you can install a heated pool, this will increase both the initial and ongoing costs, particularly if you live in colder climates.
Swim Spa: A swim spa is designed for year-round use. Whether you’re dealing with chilly winter mornings or summer heat, you can adjust the water temperature easily. Michael Phelps Swim Spas have a built-in heater and the control panel. Plus, the full-foam insulation helps maintain temperature, making it perfect for any season and any climate.
Pool cost
Lap Pool: While the price of a lap pool varies depending on size and materials, the average cost of installation can be significant. According to Home Advisor, the cost of a lap pool in 2025 is $44,00. For a small pool, this could be a more affordable option, but prices can easily exceed $100,000. Additionally, heating, landscaping, and maintenance can drive up costs.
Swim Spa: When budgeting your backyard project, the cost of a swim spa is typically between $20,000 and $60,000.
Pool design and size
Lap Pool: Lap pools are typically long and narrow, requiring a minimum width of 4 feet for swimming. A traditional pool will often be 8 to 10 feet wide. In addition to the size, you’ll need to plan for how to get in and out of the pool — steps, grab rails, and other design considerations are essential to ensure a safe and accessible swimming experience. You may also want to add a spa to complement your lap pool.
Swim Spa: Michael Phelps Signature Swim Spas offer several models ranging from 17 to 19 feet in length and 8 feet wide. These spas are ideal for smaller backyards and provide ample space for lap swimming. The MP Momentum Deep, for example, features two bodies of water: one for swimming and another for hydrotherapy. If you want even more room, the 18-foot MP Signature Deep offers a spacious swim area along with integrated seating for relaxation. Additionally, you can customize your swim spa with options like lighting packages, a Bluetooth sound system, and a custom raised deck for a more luxurious look.
