If your idea of relaxing at home is soaking in warm water on a comfy seat, you've probably thought about getting a hot tub. That said, a standard jacuzzi is a substantial investment, and you'll need a designated place for it. But with an inflatable hot tub, you can blow it up when you want to use it, and store it when you don't. Plus, blow-up tubs are portable, allowing you to set them up almost anywhere and move them around as you please.

Aside from providing flexibility, inflatable jacuzzis typically come at a fraction of the price of their standard counterparts. Whether you're looking for an alternative to a regular hot tub or want to dip your toes into the world of at-home jacuzzis before committing to one, an inflatable model is a great option.

We've rounded up the best inflatable hot tubs below.

Best for Indoor Use: Intex SimpleSpa 4-Person Inflatable Hot Tub

What We Like
  • Simple water treatment

  • Ground cloth included

  • Smaller footprint

What We Don't Like
  • No additional padding

Just about any inflatable hot tub can be used indoors as long as you have the right power available, but the SimpleSpa from Intex is a good choice due to its simple water treatment method. The hot tub itself takes around 20 minutes to set up, plus additional time to heat the water. All you need to do is adjust the chemicals using the included test strip and floating dispenser. It also includes a thermal ground cloth to minimize water damage to your indoor floors. This hot tub does not include the padded headrests that come with other Intex models, but they can be purchased later as an add-on.

Remember that any time you use a hot tub indoors, you should make sure that the space is adequately ventilated to prevent yourself from breathing in the chemicals involved in treating your hot tub's water.

Final Verdict

Our top pick is the Intex PureSpa 4-Person Inflatable Hot Tub (view at Amazon). It has plenty of space for four people, massaging water jets, and even includes cushioned headrests. The built-in water softener will please people who want the most luxurious spa experience. For a high-end option, we recommend the Bestway SaluSpa Helsinki AirJet 7 Person Inflatable Hot Tub (view at Amazon). With easy access controls, you don't have to leave the tub to change the jet settings.

What to Look for in an Inflatable Hot Tub

Size

One of the key factors to consider when buying an inflatable hot tub is how many people the tub is suitable for. Some hot tubs are designed to accommodate just two people, while others will comfortably fit four or more. While a larger hot tub means increased capacity, keep in mind that it will also require more water to fill, more electricity to heat, and a larger footprint in your patio or backyard. 

Jets

A hot tub does more than just provide warm water immersion—it also offers bubble jets to massage your muscles. If this feature is important to you, compare the number of jets when shopping for an inflatable hot tub, keeping in mind that the number of jets will also vary based on the size of the hot tub. On average, most models have between 80 and 140 jets. 

Other Features

Additional features can improve the energy efficiency, convenience, or ambiance of your hot tub. For example, some inflatable hot tubs come with an insulated cover and ground cloth to reduce energy loss. If you live in a cool climate and plan to use your hot tub outdoors, these add-ons can be an effective way to maintain comfortable water temperatures. 

Other inflatable hot tub options include a digital control panel or even smartphone controls to make adjusting temperature settings or operating the jets as easy as pushing a button. Lights are also available on some portable hot tubs, adding a fun or relaxing ambiance to your set-up.

FAQs

What can you put under your inflatable hot tub? 

While your inflatable hot tub can sit directly on grass or concrete—assuming you’ve cleared all objects that pose a puncture risk, like sharp rocks, twigs, or broken glass, you might want to consider an additional layer of protection and insulation. 

The most basic solution is to use a heavy-duty tarp, folded or cut to fit the footprint of your tub. Keep in mind that the tarp will become slippery when wet. Foam or rubber tiles can also be purchased online or from the home improvement store to create a smooth foundation for the hot tub. A more solid and long-term solution that also provides insulation is a hot tub pad. These interlocking tiles can be filled with gravel to keep them in place and raise your hot tub off the ground. 

What chemicals do you put in an inflatable hot tub?

Just like a permanent hot tub, you’ll need to monitor the water quality in your inflatable spa. It’s important to test the pH level regularly and also use additives to eliminate bacteria and prevent algae growth. If the pH of your hot tub is too alkaline or too acidic, you’ll need to use a pH increaser or decreaser. Either chlorine or bromine will need to be added to the water, and a periodic shock treatment is necessary to maintain safe water quality.

Can you use an inflatable hot tub indoors? 

If you have the space and the electrical requirements, an inflatable hot tub can be placed in both indoor and outdoor locations. If you’re thinking of using your hot tub inside, then pay special attention to the flooring in the room where you want to put it. If it’s carpet or wood, you may choose to lay a plastic barrier down or have plenty of towels on hand to protect your floor from moisture when getting in or out of the tub.

Also, you should keep in mind that the hot tub when full will be very heavy, so be sure that your floor can support the weight. For this reason, a room on the ground floor of your home is usually a better choice—and also avoids the risk of water damage to your ceiling in the event of a leak.
