What's the Difference Between Jacuzzis, Hot Tubs, and Spas?

When it comes to relaxation and rejuvenation, there are few things as enticing as a dip in a spa or hot tub. These water-based treatments have been popular for centuries and continue to be sought after for their therapeutic benefits. However, many people use the terms “spa” and “hot tub” interchangeably, not realizing that there are subtle differences between the two. In this article, we will explore the distinctions between a spa and a hot tub, and help you decide which one is right for you.

What is a Spa?

A spa is typically a larger, more luxurious version of a hot tub. It is designed to offer a complete relaxation experience, combining hydrotherapy, massage, and other wellness treatments. Spas often have multiple seating areas, allowing for socializing or enjoying a private retreat. They are also equipped with additional features like built-in jets, aromatherapy systems, and mood lighting. Spas can be found in both indoor and outdoor settings, and are commonly seen in resorts, hotels, and wellness centers.

What is a Hot Tub?

A hot tub, on the other hand, is a smaller and more basic version of a spa. It is primarily designed for soaking and relaxation, with fewer additional features compared to a spa. Hot tubs are typically made of wood or acrylic and are filled with heated water. While they may have jets for a soothing massage, they generally lack the advanced features found in spas. Hot tubs are commonly found in residential settings, such as backyards or private decks, and are a popular choice for homeowners looking to unwind and enjoy hydrotherapy benefits.

Key Differences

Size and Capacity

One of the main differences between a spa and a hot tub is their size and capacity. Spas are larger and can accommodate more people, making them ideal for social gatherings or sharing the experience with friends and family. Hot tubs, on the other hand, are smaller and typically designed for two to six people, making them perfect for intimate relaxation or quality time with a loved one.

Features and Accessories

Spas offer a wide range of features and accessories that enhance the overall experience. These can include advanced jet systems for targeted massage, adjustable water temperature and pressure, built-in sound systems, and even waterfalls or fountains for added ambiance. Hot tubs, while still offering a relaxing soak, usually have fewer features and accessories. They may have basic jet systems, simple temperature controls, and limited or no additional entertainment options.

Cost and Maintenance

Since spas are larger and come with more features, they tend to be more expensive both in terms of purchase price and maintenance costs. Hot tubs, on the other hand, are generally more affordable and easier to maintain. They require regular cleaning, water treatment, and occasional filter replacement, but the overall costs are usually lower compared to spas.

Which One Should You Choose?

Choosing between a spa and a hot tub ultimately depends on your personal preferences, budget, and available space. If you enjoy hosting social gatherings, have a larger outdoor area, and want a luxurious experience with advanced features, a spa might be the right choice for you. On the other hand, if you prefer a more intimate setting, have limited space or a smaller budget, and are primarily looking for a relaxing soak, a hot tub could be the perfect fit.

Both spas and hot tubs offer numerous health benefits, including stress relief, improved blood circulation, muscle relaxation, and reduced joint pain. Whichever option you choose, remember to consider factors such as energy efficiency, durability, warranty, and reputable brands to ensure you make a wise investment that will bring you years of enjoyment and relaxation.


While the terms “spa” and “hot tub” are often used interchangeably, there are important distinctions between the two. Spas are larger, more luxurious, and offer advanced features, making them ideal for socializing and enjoying a variety of wellness treatments. Hot tubs, on the other hand, are smaller, more basic, and designed primarily for relaxation and hydrotherapy. Consider your personal preferences, budget, and available space when deciding between a spa and a hot tub, and choose the option that best suits your needs for a blissful and rejuvenating experience.
