The Intex PureSpa Portable Bubble Massage Spa is the number one inflatable hot tub for a reason. The tub is durable, easy to maintain, affordable, and delivers top-tier performance. Intex is a company that specializes in inflatable and pool products, so they have the experience and resources to offer a high quality. The 4-person Intex Spa was their first inflatable hot tub. It is the template other tubs are constructed off of because of the consistent high level performance it has demonstrated.

Top Features of Intex PureSpa

1. Material

The Intex hot tub uses a thick 3-ply material which means it has three layers of stacked synthetic material. There’s a polyester core and a layer of vinyl on each side. Polyester provides flexibility and strength. Vinyl is tear-resistance and waterproof.

Intex outsources construction of their material to a company called Fiber-Tech. Fiber-Tech specializes in making high quality, durable, waterproof materials. The increased air pressure is spread evenly across the entire tub, which means that at any specific point the increase in air pressure is actually small. The fabric will remain strong year after year.

When the Intex inflatable spa is set up, it feels very sturdy.  Sit on the edge and it will barely sags.  This is because the inner and outer walls are connected to each other by high resistance fibers. Meaning when you sit on the edge of the tub, the walls expand outwards allowing the top to sag, but the fibers inside prevent the expansion.

2. Performance

The Intex PureSpa 77-inch Portable Bubble Massage Spa is advertised as a 4-person spa. It is round with a 57-inch inner diameter. The heater and pump are one of the best on the market. The tub ideally holds 210 gallons of water, and the heater can increase the temperature of the water 2-3° F/hr. Some of the larger spas use the same pump, which processes 460 gal/hr.

The Intex portable spa is good for camping or short-term use because it has the fastest heat rate of any of the hot tubs on the market. The heater is advertised to be effective in a temperatures over 39°. This tub can maintain a 104° temperature (which is the max temp of any hot tub) in 39° weather. Once the lid comes off, water temperature will begin to drop though.

One of the unique features of the Intex spa is its hard water treatment system. Intex is the only brand that has this feature.

There are no traditional jets. Instead, there are massage bubble jets. The air pump blows water through a tube around the bottom edge of the floor and the air escapes through pinholes rising to the surface. This creates a massage sensation.

3. Setup

The Intex inflatable spa can be set up easily by a single person. Everything that you need is included with the product. The only thing you need to buy is granular chlorine, which you sprinkle into water every few days. The air pump that is included in the heater hub has a hose that attaches to the tub to inflate it. To set the Intex jacuzzi up all you need to do is set the deflated tub on the ground pad and use the pump to inflate it. Next, connect the pump hub and fill the tub with water. Finally, turn on the pump and let it start heating the water. Setting up the tub takes around 35 minutes.

Personal Story

The Intex PureSpa Bubble Massage Portable Hot Tub was the first inflatable hot tub that I ever owned. Intex introduced this product in 2014, which was the year that I purchased it. I spent much of the first year experimenting, trying to figure out its strengths and limitations. During the summer and fall, the tub performed superbly.  The water stayed hot and clear, the walls stayed sturdy, the jets maintained their strength. I packed it away after the first summer because I had plans to travel during the winter. Tearing it down was simple and took less than an hour.

I got it back out again in the spring of 2015, and used it almost every evening that year. In 2015 I noticed that I was sleeping better and my mind was clearer. My doctor confirmed that this was the result of soaking in my tub before bed. My skin improved and I felt less stressed. This was the year that really opened my eyes to the health benefits of hydrotherapy.

The real eye opener came in the winter of 2015. I decided to leave it set up for as long as it would remain hot. Temperatures dipped below freezing but my Intex inflatable spa never dropped water temperature. I had left the tub inflated for an entire year and the performance was unaffected.

Now, as I am writing this review, I have owned my Intex Pure Spa almost for 4 years. Other than a hole I had to patch because I pushed my grill into it, I haven’t had a single problem.

Conclusion

Intex PureSpa 4-Person Inflatable Hot Tub is durable, affordable, and easy to set up and tear down. The material is some of the strongest and can last many years. The heat pump is strong which means that it can maintain 104° in cold. The sturdy tub walls, powerful pump, and overall attention to detail makes it the best inflatable hot tub on the market.
