There’s no better way to relax from the comfort of your home than with the best hot tubs. Top hot tubs can cost anywhere from $3000 to even $20,000 if you opt for one with all the bells and whistles. Because they’re such an investment, choosing the right hot tub for sale at a suitable price for you is important. You should consider how important the size and shape of your hot tub is when buying, as well as the optional smart features you can find such as Bluetooth speakers and app compatibility.
Many of the top rated hot tub companies in our guide are made in the USA, including Cal Spas and Master Spas. Some of these brands also feature in our guide to the best swim spas, which use powerful jets to create a current to swim against. When used in hot tubs though, these jets are perfect for hydrotherapy and massage therapy, and many hot tubs come with customization options, meaning you can choose the perfect amount and type of jets for your tub.
Hot tub prices are complicated because there are so many factors that determine the cost of buying, customizing, and installing them. Because of this, most hot tub companies split their tubs into price tiers as opposed to disclosing an up-front price. If you want a large hot tub on a budget, you can opt for one in a more entry-level tier. Alternatively, if you’re willing to invest in a luxury tub, you can head straight to the top tier models, which feature extras such as waterfall features and plenty of in-built jets. We partnered with BuyerZone to make the buying process easier - all you have to do is fill out the details you’re looking for, and the custom survey will match you with the best hot tub for you. For our reviews of the best hot tub brands though, keep reading.
1. Sundance Spa: Best hot tub overall
Sundance Spas offers the best hot tub features, from standard built-in smart capabilities to its adjustable Fluidix jets. Though most of Sundance’s models fall in the premium and luxury price ranges, the brand does offer a good variety of spas
across the entry- and mid-level price ranges in small, medium and large tubs. Even the less expensive models come with multiple shell, cabinet and cover color options, as well as premium features such as UV-C water sanitation and waterfalls that many other companies charge as upgrades. All Sundance hot tubs are compatible with the SmartTub mobile app, though this requires a paid subscription after the first year - a bit of a bummer.

3. Bullfrog Spa: Best hot tubs for massages
Bullfrog Spas’ unique JetPak Therapy System lets you customize your massage with 18 options that each target a different type of massage therapy. Though most hot tubs offer some degree of customization when it comes to color options and even upgradeable features, Bullfrog Spas lets you pick exactly what kind of jets and massage therapy to put in each seat.
The interchangeable JetPaks, available for most models of Bullfrog Spas, give you sixteen seat back options for each seat in your spa that require less tubing and are more energy efficient than many spas on the market. Though Bullfrog does sell hot tub models without the JetPak system, the interchangeable jets and customization options are really the big selling point of this brand. Aside from the pre-set models, Bullfrog also allows you to design your own completely custom spa, as well.

4. Hot Springs: Best hot tubs for compact areas
Hot Spring has 20 hot tub models, five of which are built for two or three people. Most of the hot tub manufacturers we evaluated have only three models, so Hot Spring offers a better selection of small spas. Three of these spas are part of the brand’s Hot Spot collection, which fall into the value price range and have 10-17 jets.
The other two are premium-priced spas from Hot Spring’s top tier Highlife collection and have 14 or 22 jets. Hot Spring also has 10 medium spas and five large spas with various price ranges, all of which come equipped with energy-saving features and are certified by the California Energy Commission.

5. PDC Spas: Best large capacity hot tubs
PDC Spas has a great selection of hot tub and swim spa combos, but it also creates some of the best large capacity hot tubs we reviewed. There's 16 hot tubs in total. The company has two three-person hot tubs, but it has eight models which fit either six or seven people. Each of these come with different features and feature in a different range of PDC's hot tub series.
There's three ranges of hot tubs to choose from. The LifeStyle Series is the most affordable of the group, with the Premium Series bridging the gap to the most premium Luxury Series. These tubs come with a 35 year warranty, but the LifeStyle models get a comparably weaker 10 year coverage.

6. Cal Spas: Biggest range of hot tubs
With so many options, the website is difficult to navigate, and Cal Spas does not have pricing guidelines for its products, which makes narrowing down your options without speaking to a dealer inconvenient. However, Cal Spas has the most hot tub models available across its six hot tub product lines. The manufacturer has 51 hot tub models and several color and upgrade options as well.
Cal Spas is one of the only spa companies we evaluated with a salt water sanitation option, as well as UV-C and ozone options. This spa brand is a great option for different hot tub shapes as it offers oval and triangle spas in addition to the usual square options. All models are made in the U.S. which makes any necessary repairs super convenient.

How to choose the right hot tub
Before buying a hot tub, there are some key considerations you need to make to ensure you choose the right one. It’s a subjective process - everyone’s space, taste and budget is different. Here are the key things to think about to make sure you buy the best hot tub for you…
How big should a hot tub be?
Make sure you choose the right hot tub size by considering, firstly, how many people will be using it, and secondly, the space you have available. Small hot tubs will fit two-three people; larger hot tubs can fit eight or more. Most hot tub manufacturer’s websites list both the dimensions of each hot tub and how many people can sit comfortably within the tub, so you can be sure you're picking the right size.
How much does a hot tub cost?
The cost of a hot tub can be anywhere from $3,000 for a budget-priced tub to over $16,000 for a top-of-the-line spa with custom upgrades. Generally, inflatable hot tubs are the cheapest; above-ground hot tubs are more moderately priced; and in-the-ground hot tubs are the most expensive.
Your budget will dictate which options are available to you, so first consider how much you have to spend on your new hot tub. Also, it's a good idea to research how much a certain hot tub might cost to run and maintain (and make sure you choose an option with a lifetime guarantee).
Hot tub manufacturers rarely list the prices of hot tubs online because there are several factors that affect the price of each sale, including geography, dealer promotions and even the time of year. Of course, this also allows retailers to negotiate a higher price with people who don’t have good bartering skills.
Many hot tub companies will categorise their selections into price ranges: budget, entry-level, mid-level, premium and luxury. However, some won't provide price guidelines unless you enquire. Bear in mind that the final price of your hot tub might differ significantly from the price of the tub itself, after you've included any upgrades or extras, installation and operating costs.
Plan where you want to put your hot tub
Where will you hot tub go? This will be a major factor in deciding which type of hot tube to get and the features you'll need, so plan the location of your hot tub carefully.
If you are placing a hot tub outside, it is best to choose a model that holds heat well, so you’re not wasting energy by constantly reheating it. You might also want to consider the view, the distance from your house, and even how visible you will be to your neighbors. If you are placing your hot tub indoors, you might want to choose an area that is well ventilated so condensation doesn’t damage your home.
Know the features you want
Do your homework. We’d recommend viewing a hot tub in person, if possible, to do a wet test. It is best to try the hot tub out before buying it, as the moulded seats are designed for an average size person and if you are on the smaller or taller size these seat can become uncomfortable.
However, there are lots of features to consider when buying a hot tub, from seating style (do you want lounge-style seating, therapeutic seats or cool-down seats?) to jet type, the water filtration system (salt, ozone or UV-C?) and more. Try to choose an energy-efficient hot tub, too. Here are some areas to think about...
Hot tub therapy options
The number of jets in the tub, in addition to the placement and type of hydrotherapy the jets deliver are important features to think about when purchasing a hot tub. Hot tub manufacturers use different techniques to imitate a variety of massage types from deep tissue to light caress. Some use a combination of water and air, some use high-pressure and others use high-flow jets. If you want a full-body massage, look for a hot tub with lounge seats and leg or feet jets. Some spa models combine hydrotherapy and aromatherapy for a more relaxing experience.
Hot tub filtration & sanitation
The filtration and water sanitation systems in your hot tub keep the water sparking and clean. Spa models use different combinations of chemicals, filters, ozone and UV-C light to make sure your water stays clean. Most of the models we evaluated use multiple filters to remove dirt and small debris from the water. Many also offer ozone or UV-C sanitation options as standard installation or upgrades. These systems eliminate or neutralize bacteria as well.
Hot tub build quality
When shopping, look into the materials used in the hot tub’s construction. Most hot tubs use an acrylic interior shell supported by a frame made of either treated wood or metal and surrounded by a wood or synthetic cabinet. As long as it isn’t exposed to elements, the frame should last the lifetime of your hot tub, no matter what it’s made of.
Pay more attention to the hot tub’s insulation, as this directly affects operating costs. A poorly insulated spa costs more to heat because the heater has to run more to keep water at a set temperature, and overworking the components can lead to early malfunction. Getting a well-insulated hot tub is particularly important in locations that reach low temperatures. To this end, look for a full-foam insulated hot tub rather than a model with partial foam insulation or one that just uses a thermal wrap.
Hot tub upgrades and extras
Most hot tub manufacturers offer a variety of upgrades and extra features. In addition to an amazing soak, most manufacturers offer Bluetooth sound systems, mood lighting and waterfall or fountain water features. Many top-tier models also have built-in coolers and external seating. Some also have smart capabilities, such as an optional Wi-Fi module or companion mobile app. These smart tubs make remotely controlling or monitoring your spa easy, and they have the added benefit of making it easy to contact your local hot tub dealer.
Hot tub appearance
Most of the hot tubs we reviewed come in multiple shell and cabinet styles, with manufacturers offering more options for higher-tier product lines. Though not necessarily the most important aspect of your hot tub, appearance does play a role in the relaxing effects of your spa. Choosing a shell and UV-resistant cabinet in colors that blend in with your backyard creates a more laid-back setting, rather than an eye-sore.
