Best Portable Hot Tub Review & Buying Guide 2018

When there’s not enough room for a regular hot tub inside or outside your home, a portable hot tub is the next best option. With the ability to inflate and deflate on demand, you can soak in a hot tub anytime and anywhere you want.

After a long day at work or a grueling workout, this will be all you need to make the aches and pains go away.

Inflatable portable hot tubs have been around for a while. And with advancement in technology, the latest models do more than just warm water and make bubbles. This will make shopping for the best portable hot tub quite challenging.

Thus, the need to read reviews and make a comparison.

With some products more expensive than others, you would want to buy the best one on the first try.

What makes the best portable hot tub?


Portable hot tubs can be made of layered vinyl or PVC and reinforced with polyester, nylon, and similar fabrics. Depending on the brand, the reinforced material may come with a proprietary name.

The unique blend of materials that Intex uses, for example, is called Fiber-Tech, while Coleman calls it Tri Tech 3 Layer Material.

Whichever it is called, it is important to choose an inflatable hot tub with reinforced walls for added strength and durability. Even when such products are less expensive than the traditional kind, you would want something that will last long enough to recoup your investment.

Some tubs are made of eco thermoplastic, while others are made of durable, all-weather and all-season material.

Design & Structure

Is the tub’s interior reinforced with a vertical l-shaped beam? Or does it have interlocking panels all around the tub? The former makes for a sturdier tub, while the latter provides insulation and additional support.

Capacity & Volume

How many people would be using the portable hot tub? A small one can accommodate two, while bigger ones can comfortably accommodate up to 6 people.

Before you choose, however, you should remember that the bigger the tub the more water it needs to fill up. A 6-people tub will

need more than 300 gallons of water that, when filled, could weigh more than 2,500 pounds.

Think your deck can handle the weight if you decide to install it on this part of your home?


You need one for safety reasons, to speed up the heating process, to insulate the tub, or for use as a stopper.

Whichever is the case, a cover will keep the heat in if it’s insulated and keep the water clean.


From inflatable seat cushions to extra filters, portable hot tubs are sold with all sorts of accessories to enhance your spa experience.

The accessories you choose should depend on how you want to use your portable hot tub.

For instance, you’re going to need a chemical dispenser if you plan to leave the tub filled for days or weeks before emptying it and putting it away in storage until the next time.

Advanced Features

Does the hot tub come with a bubble jet feature? How about a hard water system or a saltwater system? Does it come with a water heater timer? How about some LED lights to set the mood?

Some portable hot tubs come with advanced features that you might find appealing. Of course, the more features are added the higher the price.


This refers to the filter cartridge and the chemicals needed to keep the water clean and ensure the portable tub lasts longer.

Energy Use

Considering that a portable hot tub comes with a heater, you must check how much energy is needed to keep the water warm or at a temperature that you like.

A portable hot tub with a 1300-watt heater will suck up a huge amount of power. The same is true for a large portable tub. But you may be able to save on energy use with a tub timer.


Like anything sold on the market, the price will always be a factor to consider. It is important to note, however, that a portable hot tub that meets your needs and has all the features you’re looking for will be worth every penny you pay for it.

Of course, if you’re willing to sacrifice a few features to save on costs, then that is your choice. There will always be tradeoffs where price points are concerned.

But if you have the money to burn, buy the best portable hot tub among the best.

Overall Pros and Cons of a Portable Hot Tub

  • Portable and easy to store.
  • Can be used anywhere, as long as the product allows it. Some may be built specifically for indoor use only.
  • No need to build anything or use additional plumbing.
  • Best for space utilization and in places were space is limited.

One major downside, however, is that storing away your portable hot tub will mean draining the water, waiting for the tub to completely dry before deflating, and folding it in a way that it will fit the carry bag or wherever you wish to stow it away.

Best Placement

A portable hot tub can be placed indoors or outdoors and just about anywhere it fits.

But proper placement of the tub goes beyond determining the dimensions of a tub and how it will fit the size of space available. You must also ensure that area where the inflatable will be set will:

  • Enable you to drain water effectively and without causing water runoff or soil erosion. You should also ensure that the water will not drain into your neighbor’s front lawn or leave a sopping mess on the side of the road.
  • Not require additional plumbing. The tub should be close enough to the water source or has access to water without the need to install additional pipes. The idea of a portable tab is that you can use it anytime without leaving a trail when you stow it away.
  • Enable you to easily access or pass the tub when placed on an area with stairs. Make sure the size of the tub does not obstruct stairway passage when fully inflated and filled.
  • Not leave mold and other moisture problems. Remember that tubs will create a humid and moist environment that can cause mold build-up in certain parts of the house. Do you think the area where the tub is placed can handle the humidity and moisture?
  • Have strong flooring. Think about the weight of the portable hot tub when filled with water and see if the area where it will be placed can handle the thousands of pounds of weight. This is especially true if you plan to place the inflatable hot tub on a deck or elevated platform.
