Intex Octagonal Pure Spa Review | Ratings & Verdict

This is our review of the Intex Octagonal Pure Spa 4 person (updated in 2023)

Intex has been around for a long while and offers a decent range of blow-up spas.

The Intex Octagonal Pure Spa is slightly different thanks to its shape but is it the best option for you?

4 Person Intex Octagonal Hot Tub

Where Intex come up trumps is the quality construction of their spas. The puncture-resistant triple outer layer and Fiber-Tech interior provide immense stability and comfort. The 120 air massage jets provide a refreshing spa experience, and there’s plenty of room for three adults or two adults and two children.

Does having eight sides create any benefits?

Ultimately, the perfect Jacuzzi fits your family’s needs. This Octagon hot tub review will dig deep into the pros and cons to see what it offers the average family in terms of functionality and value.

We’ve been reviewing hot tubs for a long time, and believe us, some are not all they are cracked up to be, is this one? Let’s find out!

Table of Contents

The Intex Octagonal Spa has been designed to give users a top-rated experience with eight soft sides and room for four people. 

When choosing a portable inflatable spa, a few different brands are available, but Intex offers several features that others do not.

A built-in hard water treatment system softens the water, which is friendlier on the skin and better for the operating system. 

Plus, the control panel is straightforward and sets both the heat and the bubbles with ease. We were also impressed with the robust Fiber-tech walls, which keep their shape and are resistant to punctures.

Is This a WI-FI Controlled Hot Tub?

There is no W-Fi compatibility with this model, but at this price point, that’s no surprise. Hot tubs controlled by apps tend to be premium models at the moment, but we expect this will change in the future.

Does This Model Have Lighting?

Unfortunately, the Intex Octagonal inflatable hot tub doesn’t have any lighting, which once again usually incurs a higher price tag. However, floating LED lights can be purchased relatively cheaply online.

Lights can create a party atmosphere, are great fun for kids, and even improve your mental health, so if this feature is high on your list of requirements, we recommend the Paris by Lay-Z-Spa.

How Many People Can it Accommodate?

The Intex Octagon spa can theoretically fit four people, but we found the capacity to be a bit cosy for comfort. Saying that there is more legroom than a lot of other 4-person tubs.

Most customers say there is plenty of space for two adults and two kids, which is ideal for many families.

What About Safety Features?

All Intex models have a GFI (Ground fault interrupter), which cuts power to the tub almost instantaneously if an electrical problem is detected.

One thing to mention about Intex spas is that the cable length is relatively short, about 3.5 meters, so you might be tempted to use an extension cord. DON’T! It’s extremely dangerous.

We recommend getting an outdoor outlet installed by a professional electrician.

Detailed Review

How comfortable is this 8 sided hot tub?

The unique shape of the Octagonal Jacuzzi gives everyone their own comfortable place to sit, and the jets are positioned around the circumference, so everybody enjoys the same massage experience.

The thermal mat keeps the bottom of the spa bubble tub from feeling cold, and the sturdy sides are perfect for sitting on out of the water. As with most mid-range tubs, seating is unfortunately not included, but Intex sell seats separately if needed.

Running costs

To keep the Octagonal spa fully heated and the filter running daily, the electricity cost is approximately £10 a week, which is about average for a hot tub.

To keep the heat loss to a minimum, Intex has added some extras, such as an insulated cover and the thermal under mat.

Chlorine and filters also need to be purchased, but this is the same with all spas.

Heat up times

The heater with this spa warms the water by 2 degrees every hour, in line with most other models on the market and it’s about average for a 4-person spa. It will take between 12 to 24 hours for the hot tub spa to heat up to the 40-degree maximum.

This timeframe can be reduced by placing your blow-up tub in a sunny position and adding some warm water when filling.

How noisy is this model?

Reviewers report no real problems with noise when the spa is working – it’s a gentle hum in the background. This is because the spa has a solidly built heater and pump, which helps keep things quieter.

The hard water treatment system also prevents the build-up of scale and residue, which can also increase noise levels.

Making sure that the filters are changed regularly in accordance with the maintenance instructions will keep the pump in top condition and running quietly.

Winter usage

It comes with a thermal mat and an insulated lid, so the water doesn’t lose its heat too quickly, even in colder weather.

With the control panel within easy reach, you don’t have to get out of the hot water to change the bubbles, which is a great added bonus.

Placing all hot tubs in a sheltered position or under hot tub pagodas in the winter will help you enjoy it even more.

Price and discounts

The Octagonal is fantastic value for money, but it is pretty basic with no added extras like Wi-Fi or lights.

Savvy buyers should shop around as there are often discounts, especially when newer models are coming out towards the end of the year.

Warranty and support

As long as your blow-up spa is purchased from a verified dealer, you will have a 12-month guarantee.

All you need to do is head to the Intex website, fill out the warranty form providing proof of purchase and you’re sorted.

Previous Buyers Reviews

The reviews of the Intex octagonal hot tub come out at 3.5/5 stars but that is with a limited number of reviews.

It’s best to take a thorough look at the spec of the model and see if it’s right for you.

We rate it well, and it can be found on our latest reviews page.

Intex has a good reputation with their hot tubs, getting some really good reviews and the Octagonal hot tub model is no different.

This model is ideal for small families who want a budget model with more space, and those who want something that looks a bit different.

First-time buyers who want a no-hassle plug-and-play spa and people who live in a hard water area.

How Does it Compare?

WAVE Spa Rome

It took us a while, but we eventually found another eight-sided tub for comparison. The Rome by Wave Spa costs more, but you get some extra space with this model, seating up to six (although we think this is a bit of a tight fit)

Wave Spa is a relatively new kid on the block, based in the North East of England and they’re definitely one to watch.

The sleek marble design of the Rome won’t be to everyone’s taste, but it would fit well in contemporary gardens and the features of both are pretty well matched.

MSpa C-TE041 Tekapo

This fantastic square-shaped hot tub accommodates up to four people with 108 innovative air jets and has a maximum temperature of 38 degrees which is slightly less than Intex's 40 degrees. 

It is available in a charcoal grey/metallic blue and includes a safety buckle for the cover. It measures 1.58m x 1.58m W and has a 650L capacity which is considerably less than the 795L the Intex can hold.

It's certainly a smaller model than the Intex, but it is great for a family with not a massive garden. 

How to Set Up The Octagonal Spa

Like all the best inflatables, the setup of the Octagonal shaped spa is a breeze with no tools needed, although some customers have remarked the instructions could be a little clearer.

First, you need to decide where you are placing the tub; it should be a flat area with no sharp stones underneath and preferably in a sheltered position. Once you have the perfect spot, you need to unpack the spa connect the pump and inflate, which takes just a few minutes.

There are plenty of online tutorials should you need them.

Last Word

Providing relaxation at the touch of an (easy to reach) button, this lovely Intex Octagonal Pure Spa is ideal for couples, friends or small families and fits into even the most compact garden.

There are 120 jets, so you are ensured of a full body massage and soothing spa experience. Like all Intex models, a water treatment system is incorporated, which makes the water extra gentle on your skin.

We liked this spa; the quirky shape is not as we first thought, purely a design feature; it really does give more space.

This blow-up spa an excellent choice for first-time buyers who want a budget option that offers some awesome features as standard.
