Backyards are getting smarter—and smaller—which is why compact luxury features like plunge pools are quickly becoming the go-to choice for modern outdoor spaces. A plunge pool is a small, deep pool designed more for relaxation, cooling off, or hydrotherapy than for swimming laps. It delivers the aesthetic and therapeutic appeal of a full-sized pool without requiring the same footprint or upkeep. Whether you’re a homeowner looking to elevate your outdoor living, a renovator planning a tight-space transformation, or simply a pool enthusiast exploring your options, this guide will walk you through everything you need to know about plunge pools.
A plunge pool is a small, deep pool designed primarily for relaxation, cooling off, or low-impact exercise rather than swimming laps. Typically ranging from 4 to 8 feet deep and much shorter in length than traditional pools, plunge pools offer the benefits of water therapy in a compact form. They can be installed in-ground or above-ground and are often used as a stylish focal point in smaller backyards, patios, or courtyards. While they may not replace the functionality of a full-size swimming pool, plunge pools are ideal for those seeking a refreshing dip, a place to unwind, or a modern, space-efficient water feature.
Plunge pools are characterized by their compact size and depth, making them an ideal fit for small yards or tight outdoor spaces. Typically measuring between 6 to 12 feet long and 4 to 8 feet deep, they’re deeper than they are wide, allowing for full-body immersion while minimizing the overall footprint. Most plunge pools are built for soaking, cooling off, or light water exercise like resistance training. They can be installed in-ground or above-ground and often feature sleek, modern designs. Many include optional spa-like features such as jets, heating systems, or integrated seating. Their minimalist size also makes them more energy-efficient and easier to maintain than traditional pools.
Plunge pools come in a variety of sizes, but they’re generally designed to be compact while still deep enough for full-body immersion. Standard plunge pool dimensions typically range from 6 to 12 feet in length, 6 to 8 feet in width, and 4 to 7 feet in depth. A common size is approximately 8 feet by 8 feet, providing a square shape that suits small backyards or patios well. While custom sizes are available, most plunge pools are intentionally kept small to conserve space, reduce water usage, and maintain energy efficiency, making them an ideal solution for urban homes or properties with limited outdoor space.
The minimum size for a plunge pool typically starts at around 6 feet by 6 feet with a depth of 4 to 5 feet. This compact footprint allows for full-body submersion while still fitting comfortably into tight backyard spaces, courtyards, or even side yards. While you won’t be doing laps in a pool this size, it’s perfect for cooling off, relaxing, or enjoying hydrotherapy. These smaller models are especially popular in urban environments where outdoor space is limited but homeowners still want the benefits of a water feature or spa-like retreat.
Plunge pools are known for their depth relative to their compact size, typically ranging from 4 to 7 feet deep. Most standard models fall around the 5- to 6-foot mark, which is deep enough for full-body immersion and allows for comfortable soaking or therapeutic use. Some custom plunge pools can be built even deeper, depending on design preferences and local regulations. This added depth enhances their cooling and hydrotherapy benefits, making them ideal for those seeking relaxation or recovery without needing the space or maintenance of a traditional swimming pool.
The cost of a plunge pool can vary widely depending on size, materials, installation type (in-ground or above-ground), and added features like heating, jets, or custom finishes. On average, you can expect to pay between $15,000 and $35,000 for a standard in-ground plunge pool. Above-ground or prefabricated models may start around $10,000, while fully custom-designed pools with high-end features can exceed $40,000 or more. Compared to full-sized swimming pools, plunge pools are significantly more affordable, not just in initial cost, but also in long-term maintenance, water usage, and energy consumption.
The main difference between a plunge pool and a traditional swimming pool lies in their size, depth, and purpose. A plunge pool is much smaller in length and width but often deeper relative to its size, typically designed for soaking, cooling off, or hydrotherapy rather than for swimming laps. Traditional pools are usually larger and shallower, offering ample space for recreation, exercise, and group activities. Plunge pools are more suited to compact spaces and require less maintenance, less water, and lower energy costs, making them an attractive option for urban homes or those focused on relaxation rather than activity.
Plunge pools offer a wide range of benefits, especially for homeowners with limited space or those seeking a low-maintenance water feature. Their compact size makes them ideal for small backyards or patios, while still providing enough depth for relaxation, hydrotherapy, and cooling off during hot weather. They’re also more energy-efficient and use less water than traditional pools, which can result in lower utility bills and reduced environmental impact. With customizable designs, optional spa features, and faster installation times, plunge pools combine luxury and practicality in one sleek package.
While plunge pools have many advantages, they’re not ideal for everyone. The limited size means they’re not suited for swimming laps or large-scale pool parties. Families with active kids or individuals seeking recreational play space may find them too restrictive. Additionally, custom features such as heating systems, jets, or high-end finishes can significantly add to the total cost. Because they’re less common than traditional pools, permits or installation expertise may vary depending on your area. Overall, they’re an excellent fit for relaxation, but not for high-energy water activities.
Plunge pools are generally easier and less expensive to maintain than full-sized pools due to their smaller water volume and reduced surface area. Routine tasks, such as cleaning, balancing chemicals, and inspecting equipment, still apply, but they typically require less time and fewer resources. Optional features, such as covers and automated systems, can further simplify maintenance. However, like any pool, regular maintenance is essential to ensure water quality and prolong the system’s lifespan.
It’s possible to install a plunge pool yourself—especially prefabricated or above-ground models—but it requires a fair amount of planning, tools, and labor. You’ll need to consider factors like site preparation, plumbing, electrical work, drainage, and permits. DIY installation can save money upfront but comes with potential risks if not done correctly. For in-ground or custom plunge pools, hiring a professional installer is highly recommended to ensure safety, compliance with local codes, and long-term durability.
Plunge pools are a smart choice for urban homeowners, retirees, busy professionals, or anyone wanting a low-maintenance way to enjoy water therapy or relaxation at home. They’re especially ideal for those with limited yard space, people recovering from physical strain, or anyone looking to enhance their backyard with a modern, spa-like feature. If you want the benefits of a pool without the size, cost, and upkeep of a traditional one, a plunge pool might be exactly what your outdoor space needs.
