What to Consider When Choosing the Best Inflatable Hot Tub

When shopping for an inflatable hot tub, there are some key factors to consider. The following sections detail some of the most important qualities to keep in mind when shopping for the best inflatable hot tub for your backyard.

Size and Shape

Inflatable hot tubs tend to take up less space than traditional, permanently installed models. If you have limited outdoor space, however, it’s important to be mindful of dimensions when shopping for an inflatable tub to make sure it will fit.

Most inflatable hot tubs on the market are meant to accommodate two to four people, while some larger versions can accommodate six or seven. Hot tub capacity is typically measured in gallons, with most products on the market having a capacity that ranges between 175 and 275 gallons. Manufacturers typically measure the capacity at the point where the tub is 80 percent full.

The majority of inflatable hot tubs on the market are round, but square-shaped models are also available. Square-shaped tubs tend to provide more legroom for bathers and fit better if placed against a wall or tucked into a corner on your deck or patio.


The material used in the fabrication of your inflatable hot tub will contribute to its durability and longevity. Inflatable hot tubs typically feature layers of sturdy materials like vinyl and PVC. The more layers it contains, the more durable the product will be. Materials labeled as “TriTech” or “FiberTech” are triple-ply and will ensure that your tub is puncture-resistant. Some models offer reinforced walls which makes them even more long-lasting.


Inflatable hot tubs feature one of two types of jets:

  • Air jets (or bubble jets) are air-powered and provide a gentle massage. They typically use a higher number of jets to achieve a more powerful effect and require minimal maintenance. Air jets are the primary style of jet used in inflatable hot tubs.
  • Hydro jets (or water jets) are water-powered. Fewer jets are required to achieve a powerful massaging effect. Water jets require more frequent maintenance and should not be paired with aromatherapy oil or bath salts because they risk causing damage to the system. They tend to have a higher price point than air jet tubs. Hydro jets are more commonly found in permanent hot tubs than inflatable hot tubs.


While traditional hot tubs come equipped with built-in seats, most inflatable models do not. They are constructed to be comfortable without the use of individual seats. You can, however, purchase additional, removable seating for your inflatable hot tub. These seats can be moved around to create the ideal seating configuration. Shorter adults and children may benefit from a hot tub booster seat.

Filtration and Pumps

Inflatable hot tubs come equipped with filtration systems and pumps for heating the water and powering the jets.

  • Filtration systems are included with all inflatable hot tub models and keep the water clean and free of dirt and debris. The filters need to be cleaned periodically and should be replaced according to the manufacturer’s instructions. Some models are additionally equipped with hard-water filtration systems to reduce calcium buildup.
  • Pumps heat the water and power the jet systems, propelling either air bubbles or water to create a massaging effect. Some multi-functioning pumps also work to inflate the tub.

Additional Features

Most inflatable hot tubs on the market come equipped with an insulating cover, a ground mat, and a digital control panel. Some models have additional features, including:

  • Cupholders
  • Removable headrests
  • Customizable jet settings
  • Adjustable LED lights

How We Chose the Best Inflatable Hot Tubs

After evaluating all the dreamy and relaxing features that many inflatable hot tubs on the market have, we believe that this selection of top picks has the best to offer when it comes to water and seating capacity, water filtration systems, included accessories, and special features.

Each of the inflatable hot tubs has ample water and seating capacity to ensure you are getting a tub that is your preferred size along with built-in water filtration systems for clean, safe water. Many shoppers may also take delight in the generous number of air jets included, with some options having over 114 included.

The above picks also have special features like a rapid heating system, cushioned floors, digital control panels, and even LED lights for the ultimate at-home spa experience. However, it should be noted that many of the products above are not all suited for year-round use, as cold weather may cause these tubs to malfunction.


Q: What chemicals do you need for an inflatable hot tub?

In order to keep the water in your inflatable hot tub clean, look for a sanitizer like chlorine or bromine. Periodically, you might need to oxidize or “shock” your tub. Shocking products typically come in granule form and contain either chlorine or bromine.

The chemical you use for sanitizing should match the product you use for shocking, so a chlorine sanitizer should be paired with a chlorine shock treatment, and vice versa. Additional chemicals may also be needed to balance the pH of the water in your inflatable hot tub.

Q: What should you put under an inflatable hot tub?

It’s important that the ground underneath your inflatable hot tub is level. Many hot tubs come with insulated mats to place under them. When putting your inflatable hot tub on a wooden deck, using anti-microbial multi-use deck tiles can help prevent the growth of mildew and bacteria underneath your tub.

Q: How do you drain an inflatable hot tub?

To drain your inflatable hot tub, ensure the power is turned off, and then use the attached hose that comes with most models to allow the water to drain. Depending on where you live—and the pH level of the water—it may or may not be recommended to drain the water into your lawn or garden. In some locations, water from hot tubs must be drained directly into a sewage system.

Q: How do you clean an inflatable hot tub?

The cleaning instructions for an inflatable hot tub vary slightly from those for permanent hot tubs. The water in your hot tub should be drained and replaced periodically. When the tub is empty, it’s advisable to wipe down all interior surfaces and lid with a cloth or sponge and then rinse with cold water. The filters should be cleaned regularly by running them under cold water.

Q: How long do inflatable hot tubs last?

With proper use and regular maintenance, inflatable hot tubs should last for approximately five years.
