Key features of Intex PureSpa:

Personalized Heating

One of the best things about this intex inflatable hot tub is that you will get a personalized experience each time you take a dip in the tub. This is because of the intelligent heating system which adjusts to fit your personal temperature preference. Unlike other spa sets that get too hot or do not get warm enough, this tub will take out the hassle of going through countless adjustments in your settings to get the right temperature. Your personal spa should reduce stress, not add to it and this tub will guarantee you a stress-free spa experience.

Apart from this, this spa made by the famous intex brand features an insulated cover and lock to help minimize heat loss. That means, you also don’t have to worry about the water getting cold over time. You can stay and relax as much as you want, and it will maintain the ideal temperature for you. The cover also has a lock to provide added safety.

The water temperature reaches up to 104 degrees Fahrenheit and you can increase or decrease it as you please (104° is the legal max). To reach the maximum temperature, keep in mind that the outside temperature must be at least 50 degrees.

Hard Water Treatment System

The spa features a built-in hard water treatment system which means the water in the tub will be gentle on your skin as well as your clothes. It will also prevent damage to the spa system. Because of this hard water treatment, there will be no build-up of hard water so that the water has better flow. It will also give your spa a longer lifespan because hard water could cause damage to it.

Creates Suspended Crystals

The intex spa system features an advanced technology that allows it to create suspended crystals. It generates an electromagnetic field that agitates calcium and other minerals in the water which then creates the crystals. These suspended crystals are kept in the cartridge of the filter so that the water in your spa will always be soft.

Control Panel

It includes an easy to use digital control panel which allows you to activate the 120 high powered bubble jets. This produces the bubbles on the interior of the spa giving you a relaxing and refreshing massage. This control panel will also let you adjust the temperature of the bubble sprays. It’s covered with a hassle-free high-quality plastic so that it’s safe and protected.

This panel features a digital display with clear colored numbers and symbols so you can easily see the temperature and other settings that you want to adjust on the system. It has a user-friendly interface so you don’t have to be an expert to configure your spa system.

Fiber-Tech Construction

The material of the tub is a highly durable fiber tech construction and it can withstand heavy-duty use. it also provides maximum comfort so you can sit and relax in the tub as long as you want. It has a 3-ply laminated, puncture-resistant material so it doesn’t easily incur holes even if you use it outdoors.

Simple Maintenance

The spa is easy to clean and maintain. It includes two filter cartridges that are easy to replace. You don’t have to call a professional to do the replacement for you.

Convenient Storage

The Intex PureSpa is portable so you can easily transport it from one place of the house to another. The exterior has integrated grab handles with comfortable grips so you can move it around even when inflated.

The set comes with a carry bag so you can put it away easily when not in use or bring the spa system with you when you travel.

Easy to Set Up

The spa system is considered a plug and play system. It’s fast and easy to install and you don’t need an expert to set it up for you. You will receive a package that includes several units so you are aware of the different parts that you need to install. It comes with a DVD that will provide you with clear and easy-to-follow instructions to properly set up your spa. No special equipment necessary that is not included.


The Intex PureSpa inflatable hot tub is a complete set that comes with all the necessary accessories you will need to inflate, use, and maintain it.

Heater pump

The spa comes with a heater and this is what keeps the tub warm.

Chlorine Dispenser

It also includes a floating pool chlorine dispenser. You can use this to kill algae or germs that could form in the water inside the tub. It is a drifting container so you can immediately dispense the right amount of chlorine into the water if you need to. You can use chlorine tablet computers which are included when you first purchase the set.


The cover for the tub is also inflatable. It is designed with durable belts and matching buckles to keep the spa safe and secure. It has a slightly bigger diameter than the tub and you have the option to keep it on or take it off by twisting it.

Good deal!

This is a bigger brother of the Intex 77″ spa. It has all the features of the smaller sibling, but is more spacious and holds more water. The official seating capacity is 6 people. It’s definitely possible with close friends and a lot of legs touching. There are currently no other bigger inflatable hot tubs than this anyway. The picture above will give you a nice example of how spacious it is. 

If you want exact information, take a look at the specs below. With a capacity of 290 gallons of water, this thing is a monster with a weight of 2400 lbs when full!

In comparison to the smaller 77 inch Intex PureSpa which has 120 bubble jets, this one has 140.

Our take on this? You won’t notice the difference. More jets are needed due to bigger circumference, but the difference in number is not important at all.

Both intex hot tubs share the same heater and blower, which means this one will take slightly longer to heat but will hold it’s temperature longer.

But should you buy this hot tub? Let’s see whether it lives to its name, read this review, and be prepared to reconsider.

Frequently Asked Questions

What does E90 error mean on Intex hot tub?

Alarm code E90 means no water is flowing through the water pump/heater unit.

Here's how you can troubleshoot the issue, definitely check the third tip, as it's a common cause of the E90 error:

1. Check if the filter is clogged

The easiest way to do it is to follow these steps:

  1. Turn off the control unit
  2. Take out the filter
  3. Turn the control unit back on and try to run it without the filter

If it runs, the filter is probably providing too much resistance for the water to flow through it. Clean it up in warm soapy water (soak it there in half an hour, shake it to loosen the dirt), then rinse thoroughly.

2. Check if the pump motor works

If the error appears without the filter installed and instantly after turning the hot tub on, it's possible that the water pump motor failed and has to be replaced. Please contact the seller or manufacturer directly for more information or warranty replacement.

3. Check if the water flow sensor is clean

This requires a tiny bit of disassembly (but it's very easy and straightforward). Check out this video:
