Best Inflatable Hot Tub – What to Look for?

Owning an inflatable hot tub introduces you to the luxuries only a quality spa could offer. You create an outdoor focal point for your family and friends. If you don’t have one at the moment, don’t worry. There are not a lot of factors you need to keep in mind as you buy the best inflatable hot tub.


Most of the top rated inflatable hot tubs on the market feature extremely strong materials. Some manufacturers use a combination of PVC polyester and other materials to produce a strong, scratch resistant build. Some tubs feature highly reinforced fiber, and an addition of I-Beam technology to keep the tub’s walls sturdy and wobble free. Your ideal tub should be made from a strong material that can guarantee protection from pet scratches or accidental pitches. Since it’s an inflated device, its walls should also be supported by materials that prevent wobbling.

Something else to look out for in the tub is the ability to keep hot water warm. Many inflatable hot tubs are poor at heat insulation, making your water get cold too soon. Find a tub with great heat insulation so that your energy bills remain low.


Do you want a hot tub for yourself? Is it a place you’ll be taking your friends? Tubs come in all sizes and shapes, and you’ll want to invest in the size of a tub to meet your situation. A small inflatable hot tub fits 1 or 2 people. A small tub will be great for a couple with limited indoor or outdoor space, but it will certainly not suit the needs of a big family. The average inflatable tub first in 4 to 6 people costs between $200 and $500. If you choose a medium sized tub, keep in mind that you’ll need a bigger space for its installation.

In addition to space, a hot tub’s size does affect its ability to fill in hot water fast. Bigger tubs will take longer to heat water, meaning you have to turn on the water heater some time prior to getting in. Also, not all inflatables are meant to work indoors.


A hot tub cover, like any other cover, protects the tub. A quality cover that cannot be removed by children or pets will provide maximum protection against direct sunlight, bugs, and dirt. Even if you don’t have trees around the tub, trash, insects, and twigs will always find their way to your tub. This can be dangerous for the drainage system and water filters. With an open tub, the water also gets polluted faster, leaving you with no choice but to refill the tub every day.

If you are hesitant to buy an inflatable tub because you have kids and pets at home, buying a tub with a cover is the best solution for you. You will not only keep your pet and kids safe, but you will also help the tub last longer. Continued exposure to direct sunlight is not good even for tubs. Another advantage of a hot tub cover is its ability to enhance heat retention. During the cold season, your tub will stay with warm water and save you from paying high energy bills.

As you buy an inflatable tub, however, know that covers can be different. Choose a tough cover made from long lasting materials. Additionally, check the cover’s R-value for heat insulation. The higher the R-value, the better the cover will beat heat retention.


The right accessories in an inflatable hot tub can add therapeutic effects, enhance tub efficiency and overall durability. A digital control, for instance, makes it a lot easier to regulate water temperatures and use massage jets. Here are some other accessories that could improve your experience in a modern inflatable tub.

  • Water Filters. A quality tub must have water filters to keep off germs and fungi from your tub. Water filters also eliminate debris and trash that could otherwise affect the tub’s performance.
  • Cleaning supplies. You’ll need supplies to keep your hot water tub clean in the course of its service life. Chemical floaters that can help kill microorganisms will keep the tub safe for family use.
  • LED lighting to keep your hot tub accessible at night.

Inflatable Hot Tub Maintenance

One benefit of inflatable hot tubs is that they are easier to maintain. Despite their big sizes, you don’t need a professional to help you maintain your inflatable tub. Once a week you may need to refill the tub, but the rest of the maintenance work only comes in a while.

  • Refill the Tub Regularly

    If you immerse yourself into the tub once every day, make sure you drain the water as soon as it begins to get cloudy. Manufacturers advise that you refill the tub weekly, but you can do it more often if your tub is a hot spot for your family and friends. The great benefit with regular water drainage is that it helps you avoid chemical cleaners as much as you can.

  • Clean the tub properly

    Every time you drain the tub’s water, check if there was any scale or fungal build up. Use warm soapy water to clean the interiors of your tub, the floor, and exteriors until you are satisfied. Use a scrub or soft table cloth to scrub off any debris from the exteriors. After cleaning, rinse the tub properly with clean water and it will be safe for use for another week.

  • Change Filters Regularly

    Filters are great hot tub accessories that trap debris and dirt from getting into your tub. Unfortunately, the filters are not durable, and they will need to be replaced every once in a while. For better maintenance, it’s advisable that you buy a tub with a cover. Another alternative is to buy washable filters. You will incur a lot less in tub maintenance as compared to using normal water filters.

  • Chemical Floaters

    To keep germs and micro organisms off your hot water, manufacturers often offer chemical floaters such as chlorine tablets. Buy quality hot tub maintenance chemicals and apply them every time you refill the tub with water.

  • Keep the Cover on when not in use

    A hot tub cover is one of the most important accessories you can get for your outdoor tub. It helps keep debris and pets away for longer tub service life. It also helps protect the tub from direct sunlight as well as keep your children away from it. Always ensure the cover is in use when you are not using the tub. This way you will incur fewer maintenance costs and have clean water in the tub for longer.

Can Inflatable hot tubs be used in the winter?

Most inflatable hot tubs can be used in winter. However, many of them struggle to maintain a warm water temperature if the weather reaches freezing temperatures. In addition to that, their mechanical hardware is often not insulated. If water were to freeze and expand inside those parts, they would crack.

Most manufacturers list the operating temperature of inflatable hot tubs. So if you are looking for one for winter use that would be an important specification to check.

If you will be using your inflatable hot tub in the winter, to help it keep maximum water temperature, insulate the heating unit and insulate the hot tub from the ground. If the temperature is below freezing, you should also always run the heater, which would prevent the water from freezing in the pump.

More, if you will be storing the hot tub in freezing temperatures, make sure that you drain all the water from the drains and pipes. Make sure also that you use a cover.

Bottom Line

An inflatable hot tub can turn out to be the best gift you ever gave your family and friends. However, you must have the best inflatable hot tub for you to experience the luxuries and comfort of an outdoor tub. You must have the right size, the right capacity and quality features for you to find value in the tub. Our inflatable hot tub reviews above covered six of the top tubs at the moment.
