The five inflatable hot tubs below all offer 130 air jets and heat settings up to 104°F, but they differ in construction, covers, filtration, and extra features. Compare the details with your available space and upkeep needs before choosing.

Our Picks: Best Blow Up Jacuzzi Tub reviews
1. Micyox Square Inflatable Hot Tub: Reinforced Walls and a Practical Accessory Kit
The Micyox is a square, four-to-six-person inflatable spa with 130 air jets and a heater that can bring water to a selected temperature of up to 104°F. Its listed dimensions are 73 by 73 by 25 inches, so measure your intended setup area and leave room around the tub for access and the pump system.
Its reinforced three-layer PVC walls are designed to help the tub hold its shape and resist everyday surface wear. The included ground mat adds a protective layer beneath the base, while the insulated cover can help retain warmth between soaks. A built-in pump and hose handle inflation, and the filtration system helps remove dirt and debris during use.
The kit includes two filter cartridges, covers for the cartridges, a drain adapter, a repair patch, child-safety keys, and a storage bag. That makes it a well-equipped option for someone who wants key setup and care items in one package. The product information does not provide a heating rate, so expect warming to take time rather than assuming the water will heat quickly.
Pros:
- 130 air jets and adjustable heating up to 104°F
- Reinforced three-layer PVC construction
- Includes a ground mat, insulated cover, and two filter cartridges
- Built-in pump supports inflation without a separate air pump
Cons:
- Its 73-inch footprint needs a generous, level setup area
- Heating speed is not specified in the supplied product details
Verdict: Choose the Micyox if you want a square, reinforced spa with a useful set of included accessories, and confirm the current listing and setup requirements before buying.
2. SunSwell 73-Inch Inflatable Hot Tub: Two Covers for Flexible Heat Retention
The SunSwell is a 73-inch square spa for four to six people. It has 130 air jets, a 600-watt motor, and adjustable heating up to 104°F. Its two-cover setup is a notable feature: an inflatable cover is intended to help with heating and keep out dust, while an insulated cover with a child-safety lock is designed to hold warmth between uses.
The tub uses laminated PVC, which the product description presents as more resistant to punctures than ordinary PVC. It also comes with a PE ground mat, a cup holder, and four replacement filters. The listing says each filter has a service life of 168 hours; follow the supplied care directions and replace or clean filters as instructed.
This model may suit someone who values having replacement filters and two cover options included from the start. Its 4–6-person capacity is a maximum-style range, so think about how much space you want per person: a group of four may have more room to relax than a full group of six. The product description mentions indoor and outdoor use, but you should check the manual and make sure your chosen surface and electrical setup are suitable before setting it up indoors.
Pros:
- Two covers serve different heat-retention and debris-control purposes
- Includes four replacement filters and a ground mat
- 130 air jets and temperature adjustment up to 104°F
- Includes a cup holder as well as setup accessories
Cons:
- Filter life and replacement timing require regular attention
- Full six-person use may feel less spacious than using it with fewer people
Verdict: The SunSwell is a good fit if you value its two-cover arrangement and included replacement filters more than a basic, single-cover setup.
3. Altrenxs Square Portable Spa: A Clearly Specified Capacity for Shared Soaks
The Altrenxs is a 73-by-73-inch square inflatable spa that holds 240 gallons of water. It is listed for four to six people, with the product description noting that it comfortably fits four adults and can accommodate six for casual use. That distinction is useful if you expect to share the tub often: capacity figures do not always mean everyone will have the same amount of elbow room.
Its 130 floor-level air jets create a bubble massage, and the built-in heating pump can warm water up to 104°F. The product details describe one-touch inflation and dual filters intended to catch hair, dust, and debris. An insulated cover with child-safety buckles helps keep the tub covered when it is not in use.
Reinforced multilayer PVC is intended to help the walls maintain their shape and resist everyday wear. Compared with the SunSwell, the Altrenxs highlights its stated water capacity and dual filtration rather than two covers or included replacement filters. The description does not specify a heating time, so plan for the water to take time to warm and check the manual for operating and maintenance guidance.
Pros:
- Provides listed dimensions and a 240-gallon capacity
- 130 air jets and heating up to 104°F
- Dual filters and a cover with child-safety buckles
- One-touch inflation is described as part of the setup
Cons:
- Six people may have less room than four adults
- Heating speed and replacement-filter quantity are not specified
Verdict: Consider the Altrenxs if you want a square tub with a stated water capacity and plan to use it mainly with a smaller group.
4. RELXTIME 6-Person Inflatable Spa: Color Lights and a Freeze-Protection Feature
The RELXTIME is designed for up to six people and pairs 130 air jets with a digital control panel and heating up to 104°F. Its main extras are five colors of submersible LED lighting and an automatic freeze-protection feature. The lighting adds an ambient touch, while the freeze-protection function is intended to help protect internal components in low temperatures.
The walls use laminated PVC with vertical I-beam construction, which is described as helping the tub stay rigid and resist scratches and punctures. The included filter cartridges and covers support routine water care, and the control panel lets you adjust heat and bubbles. The product description also lists several certifications, including ETL and CE.
Freeze protection should not be taken as a promise that the tub is suitable for all winter conditions. Check the manual for temperature limits and operating instructions, and do not assume the feature replaces proper care or storage. Unlike the square models with listed dimensions, the provided details do not give this tub’s footprint, so check the product listing before deciding whether it will fit your space.
Pros:
- Five-color lighting adds an optional visual feature
- 130 air jets and heating up to 104°F
- Vertical I-beam wall design is intended to support rigidity
- Includes a freeze-protection feature and filter cartridges
Cons:
- Dimensions are not provided in the supplied product details
- Freeze protection does not establish that the spa can be used in every cold-weather setting
Verdict: Pick the RELXTIME if lighting and a listed freeze-protection feature matter to you, but verify its dimensions and cold-weather limits first.
5. SEGMART Inflatable Hot Tub: Heavy-Duty Shell and Two-Cover Setup
The SEGMART is a portable spa with 130 air jets and space for four adults, according to the product description. Its heavy-duty three-layer PVC shell includes a high-density mesh core, designed to help resist punctures, stretching, and air loss. An external pump and digital control panel provide access to the tub’s heat and bubble settings.
The heating system is listed at 1,350 watts and can warm water up to 104°F. The kit includes both an inflatable cover and an insulated locking cover, plus a ground mat. These are intended to help with heating, heat retention, and keeping debris out between uses. The description also notes built-in freeze protection, but you should follow the manual rather than treating that feature as a guarantee for use in severe cold.
One important limitation is the stated California sales restriction: the supplied product information says the tub cannot currently be sold in California. The product details also suggest adding warm water for a faster start, but make sure any water you add is within the manufacturer’s instructions. Compared with the Micyox, this model emphasizes its external pump and two covers; compared with the SunSwell, it lists a mesh-core shell and a 1,350-watt heater.
Pros:
- Three-layer shell with a high-density mesh core
- Includes an inflatable cover, insulated locking cover, and ground mat
- 130 air jets and heating up to 104°F
- External pump and digital controls
Cons:
- Product information states that sales are restricted in California
- Designed to comfortably fit four adults, rather than promising roomy six-person use
Verdict: The SEGMART is worth considering if its reinforced shell and two-cover setup suit your needs, provided it is available where you live.
How to Choose the Best Blow Up Jacuzzi Tub
Measure the setup area and plan for access
Check the tub’s outer dimensions, then measure the area where you plan to place it. Leave enough space to reach the controls, pump, and filter for normal use and care. The Micyox and Altrenxs are listed at 73 by 73 inches; the supplied details do not give dimensions for every model. Also consider how you will fill, drain, and store the tub.
Choose capacity based on your usual group size
Capacity claims are best treated as a guide, not a promise of generous room for every person listed. The Altrenxs says it comfortably fits four adults and can accommodate up to six casually. SEGMART describes a comfortable fit for four adults. If you want more room to stretch out, choose based on your typical number of bathers rather than the highest capacity in the product title.
Compare heating and cover details
All five models list a maximum water temperature of 104°F, but the supplied details do not give comparable heating times. A cover can help limit heat loss between uses, and some tubs include more than one cover. SunSwell and SEGMART both list two-cover setups; the other models include a cover or insulated cover. Follow the manufacturer’s instructions for heating, covering, and safe temperature settings.
Look at wall construction and the base
Inflatable tubs need a suitable surface and careful setup. Several models describe reinforced or multilayer PVC construction, while SEGMART specifies a mesh core and RELXTIME describes vertical I-beam walls. A ground mat is included with the Micyox, SunSwell, and SEGMART. Check what comes with the model you choose, and prepare a level surface as directed in its manual.
Consider filtration and ongoing care
Filtration helps capture debris, but it does not remove the need to maintain the water and clean or replace filters. SunSwell includes four replacement filters and gives a stated service life for each; Micyox includes two cartridges, and other products list filters or a filtration system without the same replacement details. Review the care instructions and make sure you can get compatible replacement cartridges.
Check electrical and cold-weather requirements
These tubs combine water, heating, and electrical equipment, so follow the supplied safety instructions closely. Confirm the required power setup and any GFCI requirements before installation, and use the product’s directions for placement and operation. A freeze-protection feature on some models does not mean every spa can safely operate outdoors in all cold conditions. Check the manual for temperature limits, winter care, and storage instructions.
Confirm availability and local restrictions
Listings and availability can change. The supplied information says SEGMART cannot currently be sold in California, and availability was not indicated for some other products in the research data. Check the live product page for current availability, included accessories, dimensions, and regional restrictions before purchasing.
Frequently Asked Questions
How many people can use an inflatable hot tub?
It depends on the tub and how much space each person wants. Several options here are listed for four to six people, but some product details suggest that four adults may be the more comfortable fit. Check the dimensions and capacity notes before deciding.
How hot do these inflatable spas get?
All five products list heating up to 104°F. The information provided does not give a consistent heating-time estimate, so allow time for the water to warm and follow the manufacturer’s instructions.
Do inflatable hot tubs need a cover?
A cover can help limit heat loss and keep debris out when the tub is not in use. Some models include two covers for different purposes. Use and secure covers as instructed, especially when children are nearby.
Can I set up an inflatable hot tub indoors?
Some product information describes indoor use, but do not assume every room or floor is suitable. A filled hot tub is heavy, and it also needs a safe electrical setup. Check the manual and confirm that the location can support the filled tub before setting it up indoors.
How should I maintain the water?
Use the filtration system as directed, clean or replace cartridges according to the manual, and follow the manufacturer’s water-care instructions. Filters help catch debris, but they are only one part of regular maintenance.
Can I leave an inflatable hot tub outside in winter?
Cold-weather support varies by model. RELXTIME and SEGMART list freeze-protection features, but that does not guarantee safe operation in every winter condition. Check the manual for temperature limits and instructions for use, draining, or storage.
Final Recommendation
For a well-equipped square tub with a ground mat and reinforced walls, the Micyox stands out on listed features. SunSwell is a strong option if you want two covers and replacement filters included, while Altrenxs offers a clearly stated 240-gallon capacity. RELXTIME adds color lighting and freeze protection, and SEGMART emphasizes its mesh-core shell and dual covers. Before choosing, confirm current availability, local restrictions, dimensions, and the setup requirements for your home.
