Its Fiber-Tech Beam Construction ensures it is stable while also being comfortable, enhancing the spa experience. Measuring 77 inches in diameter and 28 inches in height, it provides ample space for up to four people. The PVC material used is durable, and the high-density thermal-resistant foam cover helps in retaining heat, making it energy efficient by up to 50%.

The built-in Hard Water Treatment System is a notable feature, as it makes the water gentler on your skin and the spa’s system, which can be beneficial if you have hard water in your area. The Positive Temperature Coefficient (PTC) heater effectively heats the water to a range of 68-104 degrees Fahrenheit, ensuring a warm and relaxing soak. The hot tub features 120 jets, contributing to a soothing bubble massage experience, which is a great way to unwind.

The control panel is user-friendly, although some users might find adjusting settings slightly complicated at first. Weighing nearly 100 pounds, it could be a bit heavy to move around, but once set up, maintenance is relatively straightforward. The hot tub requires assembly, which might take some time but is manageable with the provided instructions. In terms of capacity, it holds 210 gallons of water, which is sufficient for its intended use. On the downside, some users have noted that it can take a while to heat up initially, and purchasing the separate electrolytic cell to upgrade sanitization adds additional cost. This hot tub is particularly suited for those looking for a portable, energy-efficient, and comfortable spa experience in their backyard.

The Coleman Hawaii AirJet Large Square Inflatable Hot Tub is designed to comfortably accommodate 4 to 6 people, providing ample space with its 71” x 71” x 28” dimensions.

The spa includes essential accessories like a pump, chemical floater, filter cartridges, and a repair patch, which simplifies the setup and maintenance process. However, despite its benefits, users should be aware that the hot tub has limitations in extremely cold temperatures, and the water capacity at 222 gallons requires careful monitoring to ensure optimal performance.

Its round shape and 77-inch diameter provide enough room without being too bulky. The tub is made from DuraPlus 3-layer PVC material, which is tougher than average and helps resist punctures and stretching, so it should hold up well with regular outdoor use. It also features a Freeze Shield heating system, protecting it from potential cold weather damage, though it’s important to note it shouldn’t be used if temperatures drop below 39°F.

Heating is efficient, with a maximum temperature of 104°F, which is warm enough for relaxing soaks.

Setup is relatively straightforward with the included pump that inflates the tub and circulates water. Maintenance is manageable thanks to the included chemical floater, filter cartridges, and repair patch, although regular upkeep is still required to keep water clean and the spa functioning well. The control panel is basic but user-friendly, allowing easy adjustments of temperature and jets. While the tub’s size and water capacity (242 gallons) mean it’s heavier when full, which could be a consideration for moving or storing it, it offers an affordable, portable, and comfortable inflatable spa option for casual use in moderate climates. The plastic material may feel less luxurious than hard-sided models, and it lacks advanced features like LED lighting or waterfall effects, but it delivers solid value and reliable performance.
