SunSwell 73-Inch Inflatable Hot Tub: A Flexible Pick with Two Covers
The SunSwell is a square inflatable spa designed for four to six people. Its 130 air jets create a bubble massage, and the heater allows you to set the water temperature up to 104°F. The product information also highlights a 600W motor, laminated PVC construction, and a built-in GFCI safety feature.
Its two-cover setup is a useful distinction. The inflatable cover is intended to help with heating and keep out dust, while the insulated cover has a child-safety lock and is designed to help retain heat. Four replacement filters are included; the manufacturer states each filter has a service life of 168 hours, so plan to track use and replace them as directed.
This is a good fit if you want a portable spa with several included accessories and a clear focus on heat retention and safety. The trade-off is that the listing does not provide the tub’s dimensions or water capacity, which makes it harder to judge the real-world footprint and fill needs against the other square models.
Pros:
- 130 air jets and adjustable heating up to 104°F
- Includes both an inflatable cover and an insulated, lockable cover
- GFCI protection is specified in the product details
- Includes four replacement filters and a ground mat
Cons:
- Dimensions and water capacity are not listed in the supplied product details
- Filters need regular cleaning and replacement
Verdict: Choose the SunSwell if its two-cover arrangement and included safety features matter more to you than having detailed size and capacity information upfront.
Bestway SaluSpa Hot Springs: Best for Smart Controls and Heat Retention
The Bestway SaluSpa Hot Springs is a 71-inch square inflatable hot tub with a stated 222-gallon capacity and room for four to six people. It has 140 AirJets, the highest jet count among these five options, and heats to 104°F. Its Wi-Fi controls let you manage settings from a smartphone, while a power-saving timer can schedule preheating up to 40 days ahead.
Its insulation package is a key reason to consider it. EnergySense walls and a cover are described as making the tub up to 40% more efficient than similar models, though actual energy use will depend on conditions and how you use the spa. Freeze Shield is designed to protect the pump and liner in freezing weather; that feature does not remove the need to follow the manual’s operating and care instructions.
The tub plugs into a standard 120V outlet, but the listing specifically says not to use an extension cord or multi-plug adapter. It includes a cover, pump, filter cartridge, chemical dispenser, and repair patch, and comes with a one-year pump warranty. This is the strongest fit for shoppers who value scheduled heating and app control, but it is important to plan for a properly grounded outlet close to the setup location.
Pros:
- 140 AirJets and heating up to 104°F
- Wi-Fi controls and a programmable power-saving timer
- EnergySense insulation and Freeze Shield are designed for heat retention and cold-weather protection
- Includes a one-year pump warranty and US-based support
Cons:
- Must connect directly to a suitable grounded outlet; extension cords are not allowed
- Its smart controls and insulation features may be more than you need for occasional warm-weather use
Verdict: The SaluSpa Hot Springs is the best match here if you want app control, scheduled heating, and features aimed at reducing heat loss.
Altrenxs 82-Inch Round Spa: Roomy Layout with Automatic Inflation
This Altrenxs model has a round 82-inch footprint, measures 25.6 inches high, and is listed with a 264-gallon water capacity. The manufacturer describes it as suitable for up to six people. Its 130 air jets send bubbles across the floor of the spa, while the heating system is designed to warm the water gradually to a maximum of 104°F.
Automatic inflation and a dual filtration system are practical features for a portable model. The included accessory set is extensive: it lists an insulated cover, cup holder, child-safety lock, foot mat, test strips, storage bag, filter cartridges, and repair supplies. The reinforced PVC construction is intended to resist wear and deformation, but the product information does not give a specific insulation-efficiency figure or a cold-weather protection feature like the SaluSpa’s Freeze Shield.
The larger round shape may suit a yard or patio where you want an open layout and have room for its footprint. The listing is marked unavailable in the supplied product information, so confirm that it can be purchased before treating it as a practical option.
Pros:
- 82-inch round design with a stated 264-gallon capacity
- 130 air jets and heating up to 104°F
- Automatic inflation and dual filtration
- Includes a broad set of setup and care accessories
Cons:
- The wide footprint requires more space than the 71- and 73-inch square options
- Marked unavailable in the supplied listing information
Verdict: Consider this Altrenxs if you prefer a roomy round design and can confirm availability, but measure your setup area first.
Micyox 6-Person Square Spa: Straightforward Setup and Reinforced PVC
The Micyox is a square inflatable tub measuring 73 × 73 × 25 inches. It is described as accommodating four to six people and has 130 bubble jets, with water heating up to 104°F. Its integrated pump inflates the tub through the included hose, so you do not need to provide a separate inflation pump.
The three-layer reinforced PVC construction is intended to help the walls hold their shape and resist surface abrasion. A ground mat adds a protective layer underneath. The package also lists an insulated cover, child-safety keys, two filter cartridges, a drain adapter, repair patch, and storage bag. These details make it a practical basic setup, although the listing does not state the water capacity or describe advanced controls.
This option may suit shoppers who want a compact square footprint and a simple inflation process. The supplied product information marks it unavailable, so check the listing before comparing it as a ready-to-buy choice.
Pros:
- Compact 73 × 73-inch square footprint
- 130 bubble jets and heating up to 104°F
- Integrated pump handles inflation
- Includes a ground mat, insulated cover, and two filter cartridges
Cons:
- Water capacity is not specified in the supplied details
- Marked unavailable in the supplied listing information
Verdict: The Micyox is worth considering if you find it available and want a simple square spa with integrated inflation, but its listing gives less capacity information than some alternatives.
Altrenxs 73-Inch Square Spa: A Space-Saving Option with Dual Filters
This square Altrenxs spa measures 73 × 73 × 25 inches and holds 240 gallons of water. It is described as seating four adults comfortably, with room for up to six people for a more casual soak. Its 130 air jets provide a bubble massage, and the heating pump warms the water to a maximum of 104°F.
The one-touch inflation feature can simplify setup, while the dual filters are designed to capture hair, dust, and debris. The insulated cover has child-safety buckles to help keep it secured when the spa is not in use. Reinforced multi-layer PVC is intended to help the tub maintain its shape through regular use, but the listing does not provide an energy-efficiency estimate or cold-weather protection feature.
Its stated capacity and compact square dimensions make it easier to compare with the Micyox, which has similar outer dimensions but no capacity listed in the supplied details. This Altrenxs model is marked unavailable in the supplied listing information, so verify availability before making it your choice.
Pros:
- Stated 240-gallon capacity and a 73-inch square footprint
- 130 air jets and heating up to 104°F
- One-touch inflation and dual filtration
- Insulated cover includes child-safety buckles
Cons:
- Marked unavailable in the supplied listing information
- No specific energy-efficiency or freeze-protection feature is listed
Verdict: If available, this Altrenxs is a sensible compact option for shoppers who want a stated water capacity, dual filters, and a lockable insulated cover.
How to Choose a Mid-Range Inflatable Hot Tub
Measure the Setup Area Before You Choose a Shape
Measure the space where the tub will sit, then leave room around it for the pump, cover removal, and safe entry. Square tubs around 71 to 73 inches across can fit more neatly into a corner or patio layout. The 82-inch round Altrenxs needs more open space. Also check that the surface is suitable for the filled tub and that the product instructions allow your planned location.
Look Beyond the “Four to Six People” Claim
Capacity labels describe a maximum, not necessarily the amount of personal space each person will have. Compare the tub’s dimensions and water capacity when those details are available. For example, the supplied information lists 222 gallons for the Bestway, 240 gallons for one Altrenxs, and 264 gallons for the larger round Altrenxs. The SunSwell and Micyox details do not state a water capacity, so you may need to consult their listings for a closer comparison.
Compare Heating, Insulation, and Covers
All five models are described as heating water up to 104°F, but they differ in how they handle heat retention. Look for an insulated cover and any insulation details, and consider whether you will use the spa in cooler conditions. The Bestway lists insulated walls and a cover, plus Freeze Shield. The SunSwell includes two covers, while the other models list insulated covers. A cover can help retain heat and keep debris out, but it does not make every inflatable tub suitable for every climate.
Choose the Jet Setup That Fits Your Expectations
These models use air jets to create bubbles rather than describing a high-pressure hydrotherapy system. Jet counts range from 130 to 140 in the supplied product information. A higher count does not by itself tell you how powerful or comfortable the massage will feel, so consider the overall layout, tub size, and the kind of soak you want.
Check Power and Controls
Confirm the electrical requirements and the location of a suitable outlet before buying. The Bestway listing specifies a grounded 120V outlet and warns against extension cords and multi-plug adapters. It also adds Wi-Fi controls and scheduled heating. Other products list built-in heating and pump functions but provide fewer control details, so read the full instructions for the model you choose.
Plan for Water Care and Filter Replacement
An inflatable spa still needs routine water care. Check what filters, test strips, and cleaning accessories come with the tub, and find out how often the manufacturer recommends cleaning or replacing filters. The SunSwell specifies a 168-hour service life for each included filter, while other models list different filter quantities or systems. Follow the manufacturer’s water-care guidance rather than relying on filtration alone.
Account for Setup, Storage, and Ongoing Care
Automatic or built-in inflation can make initial setup easier, but you will still need space for the pump, cover, and accessories. If you plan to pack the tub away, look for a drain adapter, storage bag, and instructions for drying and storing it. Reinforced PVC can help with durability, but protect the base, keep the filter system clean, and follow the care instructions to reduce avoidable wear.
Confirm Availability and Support
Availability can change, and several options in this comparison are marked unavailable in the supplied listing information. Check the product page before deciding, and review the current warranty and support details. The Bestway listing specifies a one-year pump warranty; the SunSwell describes responsive customer service. Do not assume another model includes the same coverage unless its listing says so.
Frequently Asked Questions
What is a good mid-range hot tub for a backyard?
Among these inflatable options, the Bestway SaluSpa Hot Springs is a strong choice if you want Wi-Fi controls, scheduled heating, insulation features, and Freeze Shield. The SunSwell is another option if you value its two-cover setup and GFCI protection. Your best fit depends on space, power access, and which features you will use.
How many people can fit in these inflatable hot tubs?
Each product is described as accommodating four to six people. Actual comfort depends on the tub’s interior space and how much room each person wants. The 82-inch round Altrenxs has the largest stated footprint in this group, while the square models are around 71 to 73 inches across.
How hot can these models get?
The product information for all five models lists a maximum temperature of 104°F. Heating is gradual, and the time needed to reach your preferred temperature can depend on starting water temperature, outdoor conditions, and heat retention.
Can I use an inflatable hot tub in cold weather?
Some models include features intended to help with colder conditions. The Bestway lists Freeze Shield protection for the pump and liner. That feature is not a substitute for following the manual’s temperature, placement, and storage instructions. Check the manufacturer’s guidance before using any inflatable spa in cold weather.
Do inflatable hot tubs need regular maintenance?
Yes. You will need to care for the water, clean the filters, and replace them as directed. Keep the tub covered when it is not in use to help limit debris and heat loss. Follow the product’s instructions for water treatment, filtration, draining, and storage.
Do these hot tubs need a special electrical outlet?
Requirements vary by model. The Bestway listing specifies a grounded 120V outlet and says not to use an extension cord or multi-plug adapter. Check the electrical rating and installation instructions for the exact tub you plan to buy, and make sure your setup meets them.
Which option is easiest to set up?
The Altrenxs 82-inch round model lists automatic inflation, while the Micyox and the 73-inch Altrenxs describe built-in or one-touch inflation. The SunSwell also lists a pump and inflation hose. Setup steps can still vary, so review the product instructions and prepare the site before inflating the tub.
Final Recommendation
For a feature-rich inflatable spa, the Bestway SaluSpa Hot Springs stands out for its Wi-Fi controls, scheduled heating, insulation package, and Freeze Shield. The SunSwell is a good alternative if you prefer its dual covers, GFCI protection, and included replacement filters. If you are considering one of the other three models, check current availability first; the supplied listing information marks them unavailable. Whichever tub you choose, measure your space, confirm the electrical setup, and compare the care requirements before buying.
