Plunge Pools vs Spas: Which Fits Your Yard?

Not every backyard has room for a full-size pool, and not every homeowner wants one. If you’re working with a smaller space or looking for something that fits a different lifestyle, plunge pools and spas are two popular alternatives worth comparing. While they might seem similar at a glance, they serve different purposes and fit different types of yards. Here’s how to figure out which one is right for you.

What Is a Plunge Pool?

A plunge pool is a smaller, compact pool designed primarily for cooling off, light swimming, and relaxing rather than lap swimming or hosting large groups. They’re typically deeper than a spa but significantly smaller than a traditional inground pool, making them a popular option for homeowners who want the feel of a pool without dedicating a large portion of their yard to one.

Plunge pools work well for homeowners who want a refreshing dip during hot summer months, a stylish water feature that elevates their outdoor space, or a pool option that fits a smaller or oddly shaped lot.

What Is a Spa?

A spa, often referred to as a hot tub, is designed around warm water immersion for relaxation and therapeutic benefits rather than swimming or cooling off. Spas typically include jets for hydrotherapy and are used year-round, since the heated water makes them just as enjoyable in cooler months as they are in summer.

Spas come in a range of sizes, from compact plug-and-play models designed for two to four people to larger units that comfortably seat five to ten. This makes them a flexible option regardless of how much space you’re working with.

Comparing Space Requirements

This is often the deciding factor for homeowners choosing between the two. Plunge pools generally require more space than a spa since they’re built for movement and light swimming, even in a compact footprint. A spa, on the other hand, can fit into much smaller areas, including patios, decks, and even indoor spaces in some cases, since it doesn’t require room for swimming.

If your yard is on the smaller side or has an irregular shape, a spa may be the more practical fit. If you have a bit more room to work with but still can’t accommodate a full-size pool, a plunge pool offers a middle ground between a spa and a traditional pool.

Comparing Use Case and Lifestyle Fit

Plunge pools are best suited for homeowners who want a refreshing way to cool off during the summer, along with the visual appeal of a built-in water feature. They function more like a scaled-down pool than a therapeutic tub.

Spas are better suited for homeowners focused on relaxation, muscle recovery, or year-round use regardless of season. Because they’re designed specifically for heated-water use, spas are a natural fit for year-round relaxation, while heating capabilities for plunge pools vary by model and system.

Comparing Installation and Long-Term Use

Plunge pools are usually installed as a permanent inground feature, similar to a full-size pool, which means the installation process and long-term maintenance considerations mirror what you’d expect from any inground pool project. Our installation team can walk you through what that looks like for your specific yard.

Spas, particularly plug-and-play models, tend to have simpler installation requirements and more flexibility if you ever want to relocate or upgrade the unit down the road. Larger built-in spa models fall somewhere in between, offering more permanence while still requiring less space than a plunge pool.

Which One Should You Choose?

If your priority is a refreshing way to cool off and a stylish, space-conscious water feature, a plunge pool is likely the better fit. If your priority is year-round relaxation, hydrotherapy, and flexibility for a smaller or unconventional space, a spa is probably the smarter choice.

Some homeowners find that a spa complements a larger pool project perfectly, offering a warm-water option alongside a cooler swimming pool. Our spa lineup includes options for a range of yard sizes and group sizes, so there’s likely a fit regardless of your space constraints.

How much yard space do I need for a plunge pool?
