I’ve first known of Intex when I was scouting for an airbed years ago. They seem to be one of the pioneers of inflatable beds. They also manufacture ground pools and other inflatable stuff like toys.

Their experience with these products makes them very much qualified to manufacture inflatable spas. In fact, they have a lot of models available on the market today.

This Intex PureSpa Bubble Massage Set is a great pick for those looking for a compact and functional inflatable spa.

Below is the list of features that this inflatable hot tub has:

  • 120 high-powered bubble jets
  • Seating capacity of up to 4 people
  • 2 easy-to-replace filter cartridges
  • Built-in hard water treatment
  • Built-in heating system up to 104 degrees Fahrenheit

Aside from the inflatable hot tub and control unit, these following items are included when you purchase it:

  • 3-way test strip
  • 2 filter cartridges
  • Floating Pool Chlorine Dispenser
  • Thermal Ground Cloth
  • Inflation Hose
  • Carry Bag

You may find this product a little more costly than other entry-level small inflatable hot tubs like the Lay-Z Spa from Coleman, but the additional cost is worth it because of the built-in hard water treatment system unique from others of similar class.


Intex PureSpa Bubble Massage 4-Person Portable Hot TubFor a single person, even for a 6-footer, there is enough legroom to stretch your legs without pushing on the side walls. Anyone with a height of less than 5’6″ will have a very comfortable time, allowing them to do even simple leg exercises.

As we have previously determined, when an inflatable spa is advertised to have a seating capacity of x, it actually always means x-2 for it to be comfortable. In this case, it is listed to be a 4-person inflatable spa, but the optimal capacity is only for 2 persons. The seating capacity is perfect for couples, though. A single couple to be exact.

However, this inflatable hot tub still works great for up to 4 people. In reality, I don’t think each occupant will need to stretch his or her legs all the time.

The inner diameter of the tub once inflated is 57 inches or around 4 feet and 9 inches. If you would like to check how you would fit inside, you can take a measurement from your hips down to your feet and compare it with the tub’s inner diameter.

This PureSpa Bubble Massage has a water capacity of up to 210 gallons. You will need to take this into consideration plus the weight of people you’re planning to place the tub on a raised deck.

Heating System

This model of PureSpa from Intex has a heater built into the control unit. You can easily heat up the water with just a push of a button. The control unit will take care of the rest, making sure it reaches the temperature you have set.

The heating system can heat up the water from 68 degrees Fahrenheit to 104. It may not be as hot as your gym spa, but the maximum of 104 is still very soothing especially in colder temperatures.

It heats up the water at a rate of 2 to 3 degrees per hour. Since the rate the water is heated up is not that fast, you will need to learn to time it right when you’re going to use this portable spa. For instance, if you’re going to use it in the morning, you can turn on the heater the night before.

To make sure it heats up consistently and remains at the temperature you have set, you will need to set up the insulated cover on top of the spa. We recommend that you remove it only when you’re about to go in.

Filtration System

Most inflatable hot tubs only have standard filters installed and a chemical floater. This particular model has its own hard water treatment installed as well. There’s no need to set this system up as it is already built-in to the control unit, same as the heater.

The purpose of this hard water system is actually twofold. One is that it makes the water gentler on the skin and clothes. Second is that the system prevents any hard water build up, which if left unattended will reduce the lifespan of your inflatable spa.

Intex PureSpa Portable Tub makes use of 2 filter cartridges which are easy to replace. The control panel will display an error code for you when it needs to be replaced. There are 2 free cartridges are included when you purchase this spa.

This portable hot tub also comes with a chemical floater but it doesn’t include some free starter chlorine/bromine tablets.

Massage System

What’s a spa experience at home without a massage? Inflatable hot tubs nowadays have several options to provide this. There are those which have bubble jets, some have hydro jets while others have both.

Keep in mind that the more types of jets available in a hot tub, the more expensive it gets.

This PureSpa 77in Portable Spa has 120 bubble jets installed. This is one reason why it’s a lot cheaper than other inflatable hot tubs. Hot tubs with hydro or massage jets are more expensive.

Intex PureSpa Inflatable Hot TubThese bubble jets, installed at the bottom perimeter of the tub still delivers, though. They provide a light massage when turned on. Together with heated water, you’re sure to experience relief for your aching muscles.

Even those with recurring back and neck pain due to stress will greatly benefit from this bubble massage. Spending 30 minutes a day worked wonders for a lot of buyers.

The pressure of the bubble jets is not adjustable. If you have around 4 people in the tub, expect water to splash out. You need to take this into consideration and the best way to avoid this is to remove some water.

Take note that because of this inflatable spa’s design, you cannot turn on more than one feature at the same time. Turning on the bubble jets will disable the heater and vice versa.

If what you’re looking for are massage or hydro jets that do blast heated water, providing more pressurized massages, then this model is not for you. Fortunately, there are other models available with jets like the Intex Deluxe Portable Hot Tub which we have reviewed here in detail.


This Intex Portable Hot Tub has a dimension of 77 x 28 inches once inflated. The side walls are 20 inches thick, which gives enough room to sit on comfortably.

You also do not need to worry about the sides toppling over or sinking. This inflatable spa is designed to allow people to sit on the sides.

This is made possible by their patented Fiber-Tech Construction materials inside, which gives the tub stability and structure. The outside material is made of puncture-resistant material like a hard vinyl.

Keep in mind that regardless of the quality of the materials, it still is susceptible to puncture and tearing from dogs and cats.

When allocating a space for the tub, be sure to consider adding room for the control unit as well. The control unit is attached to the side of the tub and requires around 10 inches of space.

Setting Up

Setting up this Intex 77in Portable Hot Tub is surprisingly easy. You can have this portable hot tub set up in an hour. All you have to do is fill it up with water then turn the heater on. The instruction booklet that comes with this unit is very easy to follow.

Intex PureSpa Bubble Massage 4-Person Portable Hot TubYou do not need a separate pump to inflate the tub. It is also installed in the control unit along with the heater and jets. The unit also comes with a hose to inflate it and a pressure gauge to make sure that it’s inflated at the right level.

Intex customer support says that the length of the power cord is approximately 25 feet, which is actually a good thing. Unfortunately, some of those who bought this tub have a 7-foot cord, others have 5 or 6. At any rate, it would be safe to assume that the cord is as long as in any household appliances.

After initially setting up and filling it with water, it’s time to get the water heated. If you would like to raise the water temperature from 70 to 100 degrees Fahrenheit, then with a rate of 2 to 3 F/hour, expect around 15 hours before it reaches 100.

It is strongly advised to set up Intex PureSpa Bubble Massage 4-Person Portable Hot Tub on a flat surface. You can still have this setup on the lawn or outside on the grass, but you need to make sure no sharp debris like rocks or pebbles littered the area where it’s going to sit.


If you are planning to buy an inflatable spa, you will also need to know if you can take care of it in the long run. Owning a hot tub is a commitment, much like owning a car.

With all the benefits you get from this inflatable spa, it’s quite surprising how easy it is to maintain.

If you can spend every day or even just twice a week in your tub, then maintaining it does not even take a quarter of that time.

Like all other portable hot tubs, this model can only endure temperature as low as 40 degrees Fahrenheit. Anything below and it will eventually get damaged.

If the temperature falls below 40 in your area during winter, you will need to disassemble and store away your tub beforehand. This is when you will need to use the storage bag included with the unit, which is about the size of a military duffle bag.

You can still enjoy your inflatable spa provided you have a place to set it up where it can be safe from colder temperatures.

Even if a hard water treatment is already in place, you will still need to do your part keeping the water clean by cleaning the filters.
Intex PureSpa Bubble Massage 4-Person Portable Hot Tub
Intex PureSpa Bubble Massage 4-Person Portable Hot Tub makes use of two replaceable filter cartridges that free the water from hairs or residues from lotions. You do not have to replace the cartridges every time as you can clean it every week by hosing it down and using the dishwasher.

The chemical floater is used to help maintain the pH level of the water. You can always buy bromine or chlorine tablets from Amazon and place it in the floater.

Energy Consumption

Using this 4-Person Portable Hot Tub regularly only adds around $15 to $45 per month to your electric bill, depending on the rate in your area. It is a very minimal cost compared to the benefits that you get.

It is also a lot cheaper than going to a spa on a regular basis.

The heating system is the major component that can increase your electric bill. The best way to minimize its usage is to use the insulated at all times when the inflatable hot tub is not in use. That way, you’re sure that the water’s temperature will easily rise and not drop quickly.

Warranty and Support

No matter how good you maintain your inflatable hot tub, parts would always break eventually. It’s just a matter of how long. This is a rather true statement if all products came out of the factory with the same quality.

To accommodate this, Intex provides a warranty of one year for parts and labor.

Remember to keep your receipt with you as you will need to send proof of your purchase date if in case you need to make a warranty claim.

Consumer Reviews

Around 75% of those rated Intex PureSpa 77in Inflatable Spa gave it a whopping 4 to 5-star reviews. Even if it did not come with more powerful massage jets, the price point more than justifies the lack of it.

As with any products on the market, there are always occurrences of factory defects. This is what most of the consumers who gave this model a low rating experienced. Their control unit broke down after several uses, a few for even after a couple of hours. This is further emphasizes the benefit of having a one-year manufacturer warranty.

We always recommend that you check the Amazon reviews before purchasing to get more information from other people who already bought and used this inflatable hot tub.
