10 Best Inflatable Hot Tubs 2025 in the United States

The INTEX 28431EP PureSpa Plus Bubble Massage Spa Set is designed to accommodate up to 6 people with its spacious dimensions of 85 inches by 28 inches. It boasts a durable Polyvinyl Chloride (PVC) material with Fiber-Tech Beam Construction that ensures both stability and comfort. This makes the spa feel sturdy while providing a plush surface for relaxation.

One of its notable features is the built-in Hard Water Treatment System, which makes the water gentler on your skin and prolongs the lifespan of the spa by preventing hard water buildup. The heating system utilizes Positive Temperature Coefficient (PTC) technology, which ensures effective heat transfer and safety, allowing users to enjoy warm water consistently.

Additionally, the spa includes an energy-efficient cover that helps retain heat, thus improving energy efficiency by up to 50%. Comfort is further enhanced with the inclusion of two contoured headrests and a mood-setting multi-colored LED light. However, the spa set is quite heavy at 124.52 pounds, which might make it less portable compared to some other options in the market. The setup process, while not overly complex, may still require some assistance due to the size and weight. The control panel is user-friendly, though it might take some getting used to for those unfamiliar with such devices.

The Intex PureSpa 6 Person Bubble Massage Inflatable Hot Tub is a solid choice for those looking for a portable outdoor spa that can comfortably fit up to six people. Its size is quite generous, with an 85-inch diameter and a water capacity of 290 gallons, making it suitable for small groups or families. The tub is made from durable polyvinyl chloride (PVC) with Fiber-Tech beam construction, which helps keep the structure stable and comfortable when in use. This material choice balances durability and comfort fairly well for an inflatable model.

Heating is powered by a Positive Temperature Coefficient (PTC) heater, which quickly warms the water up to 104 degrees Fahrenheit. This system is designed for safety and efficiency, and the included energy-efficient cover with thermal foam helps retain heat, saving some energy costs. With 140 bubble jets, it provides a relaxing massage effect, though these are air jets rather than the more powerful water jets found in higher-end hard tubs.

The spa also features a built-in hard water treatment system, which is a helpful addition to protect the tub and keep water gentle on skin and clothes. Setup requires some assembly but is manageable, and the tub is portable compared to permanent hot tubs, although it weighs over 120 pounds when empty, so moving it around frequently might be challenging. For someone looking for a straightforward, affordable inflatable hot tub that delivers good bubble massage comfort and decent heating, this Intex model is a fitting option; however, those wanting stronger jets or advanced controls might find it somewhat limited.

The Coleman Atlantis AirJet is a spacious inflatable hot tub designed to comfortably fit 4 to 6 people, measuring 71 by 71 inches and holding 222 gallons of water. Its square shape offers a roomy feel compared to round models. Made from durable DuraPlus PVC material, it’s built to resist punctures and stretching, which helps it stand up to regular outdoor use.

The heating system can warm water up to 104°F and includes Freeze Shield technology to protect components from cold damage, although it isn’t suitable for use in temperatures below 39°F. This hot tub features 140 AirJets that create a gentle, bubbling massage experience, which is great for relaxation but won’t match the power of some higher-end models with stronger jets. The EnergySense cover helps improve energy efficiency by reducing heat loss, which can save on electricity.

Setup is fairly simple with the included pump that inflates the tub and activates the heating and jets; portability is good for an inflatable spa, making it easy to move or store when not in use. Filtration is handled with replaceable filter cartridges to keep the water clean, a standard feature for hot tubs in this category. Customer reviews are generally positive, indicating this model is a solid choice, offering comfort and basic massage features without the complexity or cost of permanent hot tubs.
