First and foremost, we made sure each model on our list was capable of performing in extremely cold temperatures. All of them have a freeze-shield setting to keep the pipes from freezing. Each inflatable hot tub also reaches the highest temperature allowed, which is 104 degrees. To make sure these products are worth your time, we spent hours analyzing every factor and feature that matters in all budgets.
How do inflatable hot tubs compare to traditional hot tubs?
You may be wondering: Is it worth it to get an inflatable hot tub? Should you spend a little more money upfront for a traditional hard-shell spa instead? Each type of hot tub has pros and cons, so it comes down to what features are most important to you.
- Price: Inflatable hot tubs offer a significant advantage in terms of affordability. The models we evaluated range from $400 to $700, making them far more budget-friendly than traditional hard-shell hot tubs, which can cost anywhere from $3,000 to a staggering $20,000 depending on size, features and materials.
- Lifespan: While traditional hot tubs typically carry a higher price tag, they also boast superior durability and a longer lifespan. With proper care, a well-maintained hard-shell spa can last an impressive 20 years or more. Inflatable hot tubs, while more budget-friendly, do not last as long. They tend to last three to seven years.
- Portability: One of the biggest advantages of inflatable hot tubs is their portability. Unlike traditional hard-shell hot tubs, which are essentially permanent fixtures, inflatable models can be easily deflated and stored when not in use. This frees up valuable patio space for other activities and allows you to move your hot tub to various locations. If space is a premium, an inflatable hot tub offers unmatched flexibility.
- Seating: Unlike most traditional hot tubs that feature molded benches or built-in seating, inflatable hot tubs generally don't have seats. Fortunately, many manufacturers offer inflatable hot tub seats that can be purchased separately.
- Jets: Inflatable hot tubs offer a relaxing soak at home, but the jet experience might differ from what you expect at a spa. Most inflatable models utilize air jets, which propel air bubbles through the water to create a massaging effect. While enjoyable and relaxing, air jets provide a gentler sensation compared to the powerful water jets found in traditional hard-shell hot tubs.
- Heat: While both hot tub types reach 104 degrees, inflatable models struggle to maintain heat, especially in colder weather. This is because inflatable tubs rely on air insulation, which loses heat faster than traditional tubs with thicker shells. To combat this, consider adding insulation under the ground cloth and placing heavy blankets on the cover for better heat retention.
What to consider when buying an inflatable hot tub for winter
Inflatable hot tubs come with different features and settings. Identifying which factors suit your personal preference will help you choose the best model.
Size
Inflatable hot tubs offer more flexible seating arrangements than hard-shell tubs with molded seats. But this flexibility comes at a cost. The advertised diameter includes the thick, inflatable wall, which reduces the usable space. This space shrinks even further when you factor in legroom. For instance, a 77-inch round tub may seat four adults, but comfort is compromised if everyone tries to stretch out.
Consider who will be using the hot tub, and choose a size that would allow everyone to relax comfortably. A good rule of thumb is that the largest models tend to fit up to six adults comfortably. Note that if you're willing to squeeze, a square-shaped tub can seat more people than a round one due to the extra space in its corners.
Shape
While round hot tubs are popular, you'll also find inflatable squares, octagons and more. The best shape for you depends, in large part, on your available space. For instance, a square or rectangular inflatable hot tub might nestle nicely in the corner of your patio, whereas a round tub might take up more patio room than you want to spare.
Consider your designated spot for the hot tub, and choose a shape that maximizes your relaxation area without getting in the way of your patio furniture.
Heating time
Inflatable hot tub heating times depend on two main factors: the starting water temperature and the surrounding air temperature. Many models come with a heating time chart. For example, a tub might take 32 hours to reach 104 degrees if the water and air are both around 50 degrees. But if the water and air are both 77 degrees, it might take only 14 hours for the tub to heat.
In general, expect the water temperature to rise by 1 to 1.5 degrees per hour during the initial heating process.
Jets
Inflatable hot tubs offer a relaxing soak at home, but as we’ve mentioned, the jet experience differs from that of a spa. Most inflatable hot tubs utilize air jets, which propel air bubbles through the water to create a massaging effect. While enjoyable and relaxing, air jets provide a gentler sensation compared to the powerful water jets found in traditional hard-shell hot tubs.
If high-powered water jets are a must-have feature for your ideal soak, research the specific model thoroughly, or consider investing in a traditional hot tub. Look for information about jet type (air or water) as well as the number of jets. Some higher-end inflatable hot tubs may incorporate a combination of air and water jets, offering a more customizable and thorough massage experience.

FAQ
How hot is too hot when using a hot tub in cold climates?
Each of the hot tubs on this list reaches a maximum temperature of 104 degrees, which is the highest temperature considered safe for adults. According to the United States Consumer Product Safety Commission, the water temperature of a hot tub should never exceed 104 degrees: “A temperature of 100 degrees is considered safe for a healthy adult. Special caution is suggested for young children.”
What are the downsides of inflatable hot tubs?
While inflatable hot tubs offer an attractive price and are nicely portable, they come with some trade-offs. Durability is a concern, with a lifespan of just three to seven years — and some models malfunction even sooner, particularly in extreme cold.
Unlike traditional tubs with molded seats, inflatables generally require you to purchase seating separately. Maintaining a toasty soak can be a challenge because these tubs have less insulation than hard-sided models, too. This could lead to increased energy expenses for you, especially in colder weather.
What temperature should you keep your inflatable hot tub when not in use?
If you frequently use your inflatable hot tub, aim to keep it between 95 and 100 degrees to maintain the water chemistry and prevent freezing. If you use it rarely, consider deflating it between uses or lowering the temperature to around 50 degrees.
