The 7 Best Inflatable Hot Tubs of 2021

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.
