Best Hot Tub Brands

Types of hot tubs

In-ground hot tubs are generally referred to as spas, though many in the hot tub industry use the terms interchangeably. Some of the most common types of residential hot tubs and spas include:

Inflatable hot tubs are great for renters or those with limited outdoor space since they can be deflated and stored when not in use.

• Inflatable hot tubs: Inflatable hot tubs are compact and affordable but come with fewer features than sturdier portable spas made of acrylic or unicast tubs. Inflatable hot tubs are usually made out of latex or vinyl.
• Portable hot tubs: Unlike inflatable hot tubs, portable hot tubs are usually made out of durable acrylic and have a more extensive selection of available features. Though portable hot tubs are movable, they can be difficult to relocate without the help of a professional hot tub service technician.
• Plug-and-play hot tubs: Plug-and-play hot tubs are portable hot tubs that operate at 110 volts. They draw between 500 and 1,500 watts and can be plugged into a standard outlet. Plug-and-play hot tubs are popular because they are easy to install and great for relaxing or entertaining.
• Rotomolded hot tubs: A rotomolded tub and its surrounding cabinet are manufactured as a single functional unit. Also known as unicast hot tubs, rotomolded hot tubs are durable and can have features like molded seating and decorative lighting. However, they usually don’t have as many jets as higher-end hot tubs.
• Swim spas: Most swim spas come with most standard hot tub features, such as heated jets, but can also be used for exercise. 

How does a hot tub work?

Some consumers are surprised to learn that filling a hot tub doesn’t require any plumbing — all hot tubs can simply be filled with an outdoor water hose. Once a hot tub is filled with water, electrical resistance heaters warm the water to between 100 and 104 degrees. A pump forces water through an intake hose to circulate. A valve diverter then directs the heated water through the jets.

Water pumps power the hot tub jets. Like car motors, spa pump motors have horsepower, which describes how much power the motor can provide. Hot tub spa pump motors range from 110 to 240 volts. The type and number of pumps you need depend on the jet power, the speed you want and the energy you expect to consume.

Some hot tubs have more than one pump to deliver various functions, such as controlling jet power to particular seats. Circulation pumps continuously circulate water to clean and heat the hot tub. No-bypass filtration with circulation pumps sucks unfiltered water back through the pump and then redistributes it through the jets.

Hot tub costs

Depending on what type of tub you get and whether you opt for any add-ons, your hot tub cost can range from as little as $300 (for inflatable models) up to around $25,000 for the tub itself. If the tub requires installation, budget a few hundred to a few thousand for this labor.

And then there’s the ongoing cost of hot tub ownership. Though these costs can vary, you can expect to spend anywhere from $700 to $1,600 a year on required maintenance and repairs.

Long-term hot tub costs

Beyond the initial investment of the hot tub and installation, there are other long-term expenses to consider when owning a hot tub:

• Energy costs: Even energy-efficient hot tubs consume electricity to maintain temperature and run jets. Over time, these costs can add up, depending on your usage patterns and electricity rates in your area.
• Repair costs: Parts like pumps, heaters and control panels may need repairs or replacement over the years. High-quality models often require fewer repairs, but it’s wise to budget for unexpected fixes.
• Filter replacements: Filters typically need to be replaced annually or more frequently, depending on usage and water quality.
• Upgrades: Over time, you might want to upgrade features like lighting, covers, or spa steps to enhance functionality or appearance.

Understanding these additional costs can help you make a more informed decision when choosing a hot tub, ensuring you’re prepared for the full scope of ownership expenses.

Is a hot tub worth the cost?

Hot tubs can be very pricey, but many reviews on our site say shelling out the money for a hot tub was worth it — like Juan from Washington, who wanted a hot tub because it “really helps decompress some of the muscles that tightened up and contribute to nerve compression.” He said having a hot tub at home was “very convenient” for him — and that it saved him trips to the gym just to use the hot tub there.

Hot tub installation

Most hot tubs are fairly easy to get up and running with professional installation. Above-ground hot tubs are commonly placed on a concrete slab or reinforced deck. The location just needs to have enough structural strength to support the tub when full of water and people.

Decide where you want the tub to go before the delivery day. When picking a spot, consider your comfort and convenience. For instance, if you live in an area with cold, snowy winters, try to put the spa close to a door for easy access. If you have long stretches of warm months, under a gazebo might be a better place.

If your tub is going to be installed by a professional, here are a few tips to make the process a bit easier:

• Check the width of sidewalks, doors or gates that could cause obstruction.
• Check for overhead issues, including rain gutters or overhanging branches.
• Remove obstacles like plants, outdoor furniture or outdoor grills.

You might also need electrical access, depending on how much voltage the tub requires. Check your local building codes and zoning laws to be sure they allow for the installation of hot tubs without a permit.

How to choose a hot tub

Start by figuring out your budget so you know where to start looking. Next, think about what you want out of your hot tub experience — how you intend to use the tub will determine the features you want to look for.

1. Determine your budget

Upfront costs to purchase and install a hard-shell hot tub range anywhere from $2,000 to $18,000. If your budget is under $2,000, start by looking online for hard-shell portable or inflatable tubs, sometimes referred to as soft tubs. (You don’t need to hire an installer for either of these types of hot tubs.)

Typically, it costs around $1 a day to operate a hot tub. Some of the new energy-efficient hot tubs only cost about $20 per month to run.

Bargain hot tubs have a cheaper price tag, but energy-efficient models are a better investment because they are less expensive to run and require less ongoing maintenance. If you plan to enjoy the tub for many years, paying a little more upfront might be worth it to you.

Keep in mind that you can negotiate hot tub prices — the first price you see online or in a showroom isn’t always the best you can get. Dealers also offer financing specials and promotions, such as 0% financing or low interest rates. Additional low-cost options include purchasing a used or refurbished hot tub, though doing this requires a bit more research and caution to ensure you’re getting a legitimate product.

Don’t forget to factor in ongoing costs, such as chemicals and maintenance, to your budget. 

2. Select your hot tub size and features

Choose the size of your hot tub based on the number of people who will use it. Large hot tubs are better for entertaining, but smaller tubs are better for relaxing or intimate experiences.

Hot tubs designed to accommodate two to three people are considered “small.” Most small hot tubs are approximately 3 feet high, 6 feet wide and 5 feet long, holding about 300 gallons of water. Large hot tubs, which can fit up to eight people or more, are usually about 4.5 feet high with a diameter of 6 feet and hold up to 850 gallons of water.

Consider which hot tub benefits are most important to you when choosing features. For example, hydrotherapy massage jets are great for reducing pain and inflammation. If you’re more interested in entertainment, look into LED lighting packages, stereo setups and lounge seating.

Different hot tub styles can complement the environment and set the tone for bathers. For instance, exterior cabinets (the part that everybody sees) are available in a variety of materials, colors, patterns and textures. Remember, a hot tub is meant to be a seamless addition to your home decor, and the style and design of the shell and cabinet should reflect your personality and aesthetic.

Something to keep in mind

A brand might say a hot tub is made for five or six people, but pay attention to the dimensions. In general, an 83-inch by 83-inch model can comfortably fit about four adults — three if someone is using the “lounger.”

3. Compare hot tub models and reviews

As with most big purchases, it’s smart to make a list of three or four brands that appeal to you. Make notes of options that stand out, such as particular cabinet designs, styles of jets or seating arrangements.

Once you have your short list, you can learn a lot by reading reviews. Look out for red flags related to installation, warranty or customer service. With a hot tub, you don’t usually have to communicate with customer service unless something goes wrong.

To get the best deal, compare prices from multiple dealers and keep an eye out for promotional discounts. Retailers typically host sales each season, so you might wait to see if the price on a particular model you like goes down. You can also sometimes find great hot tub deals at state fairs or home and garden shows. Usually you will find the best pricing in fall and winter.

Look for companies that offer a warranty in case something goes wrong. It’s even better to “try it before you buy it.” If possible, visit a hot tub showroom and schedule a test soak.

4. Shop for hot tub accessories and upgrades

Picking the right hot tub is only half the game — the other half includes outfitting the tub with the right accessories and safety measures for guests. Accessories like covers, spa pillows and steps improve the functionality and appearance of your hot tub. Accessories can be purchased at any time, so you don’t have to get everything all at once.

• Hot tub cover: Hot tubs usually come with a standard cover, but for tubs that are left unattended for long periods, such as those in a second home, a coverall can significantly increase the life of the hot tub and the tub surround. Spa covers help lock in the hot tub’s heat to reduce water evaporation, which lowers owners’ energy costs. Consider a solar-powered cover for possible additional savings on energy costs.
• Cover lifter: Hot tub covers can be heavy and difficult to put on and take off. A cover lifter makes it easy to lift heavy hot tub covers.
• Spa pillows: Spa pillows, headrests and cushions are an inexpensive way to make your hot tub even more comfortable. Hot tub pillows are usually made of rubberized plastic, with suction cups to hold them in place.
• Spa steps: Being submerged in a bubbling hot tub is a relaxing way to end the day, but getting into the hot tub can be a challenge. Hot tub steps with anti-slip material reduce the danger of accidental falls. Spa steps are portable stairs that make getting in and out of your hot tub easier. Most of the top hot tub brands also sell spa steps that seamlessly blend into the exterior.
• Hot tub surrounds: Many companies sell modular components so you can add benches, seating, tables and storage around your hot tub. Surrounds are a smart alternative if you don’t already have a deck for your hot tub.
• Cup holders: Hot tub cup holders are waterproof and inflatable. If your hot tub doesn’t come with standard cup holders, aftermarket cup holders are a smart way to prevent spills.
• Spa lighting: Even if you opt out of built-in lighting features, you can add aftermarket light strips that create a colorful environment. Many lighting accessories for hot tubs are solar-powered and float.
• Gazebo or pergola: A gazebo or pergola increases your hot tub’s privacy. A gazebo is a free-standing structure with a roof. Pergolas are open structures with vertical posts and open-lattice roofing.

Saltwater vs. chlorine hot tubs

When comparing saltwater and chlorine hot tubs, it’s important to understand the key differences in how each system works and impacts users. Saltwater hot tubs use a salt chlorine generator to convert salt into chlorine through electrolysis, releasing the sanitizer gradually over time. This often results in a more stable and gentler water chemistry.

In contrast, traditional chlorine systems require users to manually add chlorine tablets or granules to the water to maintain cleanliness. These systems are typically more affordable up front, but they require more frequent maintenance and chemical balancing.

Ultimately, your choice between saltwater and chlorine hot tubs will depend on your personal preferences, sensitivity to chemicals and how much time you want to spend on maintenance.

How long do hot tubs last?

A quality hot tub lasts anywhere from 10 to 20 years if properly maintained. Bargain and inflatable hot tubs have a shorter life span of five to 15 years. Overall, how long your hot tub lasts depends on the quality of its materials, the construction and how well it is taken care of.

A good water filtration system helps keep your hot tub water clean, healthy and safe. Still, all hot tubs require water care, filter replacements and regular cleaning. Traditional hot tub water care requires you to manually add sanitizers to the tub about once a week.

No matter which approach to hot tub water care you choose, it’s essential to keep your spa covered when not in use. Following a maintenance schedule ensures your hot tub lasts as long as possible:

• Weekly: Test the spa water.
• Monthly: Deep clean the spa’s filter.
• Every two to four months: Drain the spa, deep clean the filter and refill the hot tub with fresh water.
• Yearly: Replace the hot tub filter.

Seasonal hot tub care tips

Even though hot tubs can be enjoyed year-round, there are a few things you should be doing if you live in an area that experiences extreme temperatures. During winter months, consider adding insulation or using a winter cover to retain heat. You can also lower the water temperature if the hot tub won't be used often. If you plan to drain your hot tub at any point during the winter, avoid doing it while temperatures are extremely low as this could cause pipes to freeze, damaging the hot tub.

During summer months, keep an eye on the water chemistry, as higher temperatures can promote bacteria growth. Test the water multiple times a week and adjust as needed.
