Here’s the thing about the Intex 77 inch PureSpa: you get a lot of hot tub for your money. So much so, that it is often the Best-Selling inflatable hot tub on a number of websites, a position it battles for with the all-time favorite Coleman Lay-Z Spa.

So why is it so good? Well, for a start it’s one of the largest models you can buy at this price, measuring 6′ 5″ across. This means it’s roomy enough for 4 adults to sit in relative comfort. But it’s much more realistic to see it as a spacious 2-person hot tub, where you can lay back in the water and relax.

Then there’s the powerful massage system, made up of 120 air jets and a water flow rate of 460 gallons an hour. That gives you an impressive all-over workout! It’s also built of a super-sturdy construction, capable of supporting 4 people sitting on the edge of the tub without it buckling.

You’ll see that it has lots of impressive features as well, such as the built-in hard water treatment system which is important if you live in an area where hard-water is a problem.

If you decide to buy the Intex 77 inch PureSpa, be sure to check you are purchasing the round version. There is an octagonal model, but this sells for a couple of hundred dollars more! To check out the latest deals on the circular budget model, you can follow this link over to Amazon,

Intex 77inch PureSpa Features & Comparisons

Background Info

Intex make a wide range of leisure products, most notably their above ground pools. More recently, they have gained a strong reputation for making large inflatable hot tubs that get good owner reviews all over the internet. Their 77inch PureSpa Portable Bubble Massage Spa is one of their best models, with some great feedback from owners.

It’s built with Intex’s unique Fiber-Tech construction, which consists of a series of PVC panels inside the walls that give the hot tub an internal strength so it will support you fully as you get in and out of the tub.

This is an important feature if you are a little unsteady on your feet and need to be confident in the support system of the hot tub. This construction also means the hot tub is strong enough to last you for years, as long as you apply some basic care and keep it in good condition.

It also means you can sit on the sides of the hot tub without ever worrying that it’s going to collapse or split.

The massage system consists of 120 bubble jets, in a ring around the bottom of the walls inside the hot tub. The massage system in all Intex models is good and powerful, and this makes the 77inch PureSpa great for hydrotherapy purposes.

The massage system, the heater, and the hard water treatment system are activated by a digital control panel which sits on the side of the hot tub, so you control everything without having to get out of the water. 

PureSpa Hard Water Treatment System

An excellent feature of the Intex 77 inch PureSpa is the built-in hard water treatment system. This is perfect for anyone living in a hard water area.  (You can check out if you live in a hard water area over on the softwaterfiltration website where they have a useful map).

The Intex system uses advanced technology to generate an electro-magnetic field that agitates the calcium and other minerals which are found in hard water, causing them to create suspended crystals.  The built-in filter cartridge, which is part of the package, then filters out these minerals, so the water in your spa is soft and kind to your skin.  It also prolongs the life of your inflatable hot tub.

How To Set Up Your Intex 77 inch PureSpa Portable Bubble Massage Spa

The 77inch PureSpa is an easy hot tub to set up. It takes around 20 minutes to unpack, lay out and inflate it using the built-in digital air pump. 

First off, choose the site where you’re going to place your hot tub, check it’s clear of sharp objects, and then lay out the ground mat. Then lay out your hot tub, attach the digital air pump, and switch it on. It will take only a few minutes to fully inflate.

One very useful feature of the PureSpa are the grab handles on the side. These allow you to inflate the hot tub in one place – maybe where you have more room to walk around it – and then easily move it into position once it’s inflated.  

Because of the hot tub’s sturdy construction, you don’t have to worry about it tearing when you drag it – although, as always, make sure you check there are no sharp objects. Better safe than sorry!

After that, you should plan on it taking between 30-60 minutes to fill with water, and then about 20 hours to heat to the maximum temperature of 104F. The time it takes to heat up depends on the temperature of the water, and also the temperature of the air.

Remember to put the lid on while the water is heating, as this will speed up the heating time and save you money.

One other useful tip that several owners recommend is to fill your hot tub with water from the faucet, using a garden hose. This means it takes less time for the water in your hot tub to heat up to your desired temperature.

A word of caution, though: never fill your hot tub with boiling water from a kettle, as this can destroy the hot tub skin!

Relaxing In Your 77inch PureSpa

When the water is at your desired temperature, your inflatable hot tub is ready to enjoy.  Slip into the tub, sit back, and switch on the Bubble Massage System, using the digital control panel.  If you don’t keep the water heater on, you will find that the water does cool a little.  Simply switch on the heater for 10-20 minutes, and it will soon reheat.

To keep the water as hot as possible, remember to use the insulated cover when you have finished.  This keeps the heat in and the water clean.

Once you have used your Intex 77 inch PureSpa Portable Bubble Massage Spa a few times, you may decide to buy a few extras, to enhance your spa experience.  There are some great add-ons, such as head rests, cushioned seats, and floating speakers.  

Intex have a range of their own accessories – however as we always advise: you don’t have to buy accessories from the same manufacturer that makes your hot tub. Always shop around and find the accessories you want.

The only minor complaint we have with the 77inch PureSpa is the lack of a cushioned floor. Many hot tubs these days include a cushioned or inflatable floor as standard. However for some reason, Intex have not built one in the 77 inch PureSpa Portable Bubble Massage Spa.

But don’t worry too much, if you have set your heart on buying this model.  You can do what many other owners do, and that’s purchase some cheap foam mats and place these under your hot tub.  Or you can simply buy several inexpensive hot tub cushioned seats instead.
