Intex PureSpa Bubble Massage 4-Person Portable Hot Tub Review


The Intex 77in PureSpa Bubble Massage sets itself apart from other models of the same capacity by the way it treats the water. If you’re very much concerned with water sanitation, then this is one of your better choices.

The built-in hard water treatment system keeps the water gentle on your hair, skin, and clothes. It also helps eliminate residues that can be harmful to your spa in the long run.

We’ll be expanding on this and the rest of the other features later…

As you read further, you’ll learn more about the experience that you will be having with this inflatable spa. By the end of this review, it’ll be easier for you to decide if this is the type of portable spa you would like to soak into after a long day.

Intex 77in PureSpa 4-Person Portable Hot Tub Features

Intex PureSpa Bubble Massage 4-Person Portable Hot TubThis Intex 4 Person Hot Tub set is a great pick for those looking for a compact and “almost-premium” inflatable spa. In fact, this is one of our most recommended 2-person inflatable hot tubs you can get today.

What’s good about being “almost-premium” is that it’s only missing a few high-end features that wouldn’t be such a big deal if you’re not after high-pressure massage jets and are not allergic to chlorine. In addition, this makes the unit more affordable than premium models.

This inflatable hot tub can accommodate up to 4 persons but is compact enough to even set up indoors, a great choice for during the winter months. You can certainly enjoy soaking in this the entire year.

With a programmable heating system already installed, you can have hot, steaming water waiting for you when you get home. For those days when it’ extra stressful, a soothing massage from the bubble jets can surely ease those tensions away.

You may find this product a little more costly than other entry-level small inflatable hot tubs like the Coleman SaluSpa Inflatable Hot Tub, but the additional cost is worth it because of the built-in hard water treatment, which we’ll also be discussing in detail in the following sections.


Intex PureSpa Bubble Massage 4-Person Portable Hot TubThis Intex 77in PureSpa has a size that can accommodate people who are even more than 6 feet tall. The legroom is spacious enough to allow you to stretch your legs without pushing on the side walls. If you’re height is around 5’6″ or less, you’ll be even able to do simple leg exercises.

The inner diameter of the inflated hot tub 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.

The seating capacity is perfect for couples. With this size, you can easily set this up indoors if you want to have some privacy.

This Intex 4 person hot tub has a water capacity of up to 210 gallons. If you’re planning to place the tub on a raised deck, you’ll need to take this into consideration, including the total weight of people using it.

Heating System

The amazing experience that you get when you soak in hot water also provides the most beneficial effect to your body. Not only does it feel good, but it also improves blood circulation.

Intex 77in PureSpa has a heating system 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 system can heat up the water to 104 degrees Fahrenheit, which is very soothing to most people. In fact, most people get nauseated if the temperature goes higher.

It heats up the water at a rate of 2 to 3 degrees per hour. You need to time it right when you’re going to use your spa since it takes a while to heat up, especially if you’re going to fill it up with cold water.

The insulated cover that comes with the spa helps to maintain the water temperature to keep the water hot. When you’re ready to soak in, just remove it and the water stays hot and clean from debris.

Filtration System

Dry, itchy skin, tangled hair, and soap that won’t wash away easily when rinsing are what most of us experience when we’re in the pool or spa for a moderate amount of time. If these are something that you don’t want when you step out of your inflatable spa, then the hard water treatment system that comes installed in this model is the feature that you want.

This feature is designed to break down mineral build-ups from lotions, chemicals, etc. so that the water stays soft. It also prevents the system from getting clogged up by these same minerals, ultimately prolonging the life of your spa.

Aside from the hard water treatment, this Intex 4 person hot tub comes with a standard filtration system. It makes use of filter cartridges that are very easy to clean.

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, and others have both.

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

Intex PureSpa Inflatable Hot TubThese bubble jets provide a light massage for every immersed part of your body 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 consider this and don’t fill the water up to the brim if you want to avoid this.

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 to experience are highly pressurized massage jets, then this model is not for you. Fortunately, there are other models available with this type of massage system like the SaluSpa Hawaii, which we have also reviewed in detail.


Intex 77in Pure Spa 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 don’t 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 space for the tub, be sure to consider including a space 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’re planning to buy an inflatable spa, you’ll 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 Intex 4 person hot 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’ll 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 Intex 4 Person Hot Tub regularly only adds around $15 to $45 per month to your electric bill, depending on the rate in your area. It’s a very minimal cost compared to the benefits that you get.

It’s 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.
