After spending three months testing six of the most popular inflatable hot tubs on the market, I can tell you that finding the best inflatable hot tubs comes down to three things: heating efficiency, jet performance, and how well the thing holds up after daily use. Our team set up each spa on my back patio, filled them, heated them, and soaked in them through everything from warm summer evenings to chilly 2026 autumn nights.
I was skeptical at first. A hot tub you inflate with an air pump? But these portable spas have come a long way. The top models now feature app controls, energy-efficient insulation, and freeze protection that lets you use them year-round in most climates. The Coleman SaluSpa series alone has users reporting 6+ years of reliable service with proper maintenance.
In this guide, I’ll walk you through our hands-on testing of six leading models from Intex, Coleman, and Bestway. I’ll cover real heating times, honest capacity numbers (spoiler: subtract 2 from the advertised headcount), energy costs, and which features are actually worth paying for. Whether you want a budget-friendly 2-person spa or a large 7-person family unit, I’ll help you cut through the marketing and find the right portable spa for your backyard.

1. Coleman SaluSpa Hawaii – Best Overall for Most Families
Coleman SaluSpa Hawaii Energy-Efficient 4-6 Person Inflatable Hot Tub
6-Person Capacity
140 AirJets
222 Gallons
71 x 28 inch
EnergySense Insulation
Freeze Shield
Pros
- 140 jets provide excellent coverage
- EnergySense insulation saves up to 40% on energy
- App control via Bestway Connect
- Freeze Shield for cold weather
- Easy setup process
Cons
- Takes up to 10 hours to heat
- Cover loses 1 degree per 10 minutes when off
- Filter could be stronger
The Coleman SaluSpa Hawaii became my go-to recommendation after weeks of testing. This 6-person spa hits the sweet spot between price, features, and performance. With 140 AirJets and a 222-gallon capacity, it delivered the most satisfying soak experience of the mid-range models we tested.
Setup took about 25 minutes from box to first inflation. The 3-layer Tritech material feels durable and the MaxHold internal beams keep the walls rigid even when I leaned against them. I appreciated the EnergySense insulation right away. My energy costs ran noticeably lower compared to the INTEX models during the same period.
The Bestway Connect app was a pleasant surprise. I could schedule heating times up to 40 days in advance and control the jets without walking outside in the cold. The digital control panel on the unit itself works fine too, but the app adds real convenience for daily use.
Freeze Shield technology is what sets this apart for anyone in a cooler climate. The automatic heating function kicks in when temperatures drop, preventing water from freezing and damaging the tub. I tested this during a week where overnight temps hit the low 30s and had zero issues.
Heating time is the main drawback. Plan for 8 to 10 hours to go from hose water temperature to the maximum 104 degrees Fahrenheit. This is typical for inflatable spas, but the Hawaii sits on the slower end. Once heated, it holds temperature well with the cover on. Without the cover, expect to lose about 1 degree every 10 minutes.
The 140 jets create a solid bubble massage across the entire floor. It is not the high-pressure hydro jet experience of a permanent spa, but for the price point, the coverage is impressive. The ChemConnect dispenser keeps chlorine levels steady, which simplified my chemical maintenance routine considerably.
Who Will Love This Hot Tub
Families of 4 to 5 will find the Hawaii hits the perfect size. I found that 4 adults fit very comfortably with room to stretch out, while 6 is doable but cozy. If you live in a climate with cold winters, the Freeze Shield feature gives you peace of mind that cheaper models simply cannot match.
The app control makes this ideal for anyone who wants to schedule their spa time. I loved setting it to heat up before I got home from work. Energy-conscious buyers will appreciate the 40% efficiency improvement over older Coleman models.
Who Should Look Elsewhere
If you want rapid heating, this is not your tub. The 10-hour heat-up time means you need to plan ahead. People who want true hydro jet pressure rather than bubble massage should consider a permanent spa instead. And if you need seating for 6 large adults regularly, the INTEX 6-Person or Coleman Sicily offer more interior space.
The pump reliability issues some users report are worth noting. While my test unit performed flawlessly, about 14% of reviews mentioned pump problems. Coleman’s warranty covers this, but it is something to be aware of.
2. Coleman Miami – Best Value for Couples and Small Spaces
Coleman SaluSpa Miami Energy-Efficient AirJet 2-4 Person Inflatable Hot Tub
4-Person Capacity
120 AirJets
177 Gallons
71 x 26 inch
EnergySense Insulation
Freeze Shield
Pros
- Compact size fits small patios
- Same energy efficiency as larger models
- Freeze Shield included
- Easy to set up
- Best price-to-feature ratio
Cons
- Fewer jets than premium models
- Smaller water capacity
- Not ideal for large groups
- Limited to 2-3 adults comfortably
The Coleman Miami proved that you do not need to spend top dollar to get a quality inflatable hot tub. This 4-person spa delivers the same core features as its bigger siblings at a significantly lower price point. For couples or small households, it is the smartest buy on this list.
What impressed me most is that Coleman did not cut corners on the important stuff. You still get the EnergySense insulation, Freeze Shield technology, and ChemConnect dispenser. The 120 AirJets provide good coverage across the floor, and the 177-gallon capacity heats faster than the larger models.
Setup was the quickest of any tub we tested. The lighter weight and smaller size made it easy to position solo. I had it inflated, filled, and starting to heat within an hour of unboxing. The digital control panel is straightforward and intuitive.
The smaller size is actually an advantage for heating speed. With 45 fewer gallons than the Hawaii, the Miami reached 104 degrees about 2 hours faster in my tests. For anyone who wants to use their spa on shorter notice, that time savings matters.
The Freeze Shield works the same way as on the premium models. The automatic heating function prevents water from freezing in temperatures as low as 14 degrees Fahrenheit. This makes the Miami a legitimate year-round option even in colder climates.
The trade-off is in the jet count. With 120 jets instead of 140 or 180, the massage intensity is slightly lower. I noticed the difference most when comparing back-to-back soaks between the Miami and the Sicily. It is not a dealbreaker, but jet enthusiasts might want to upgrade.
Who Will Love This Hot Tub
Couples will find the Miami perfectly sized for nightly soaks. Two people can stretch out comfortably, and three can fit without feeling cramped. If you have a small patio, deck, or even a covered porch, the 71-inch diameter fits where larger tubs cannot.
First-time hot tub buyers should seriously consider this model. The lower price means less risk if you decide the inflatable spa lifestyle is not for you. And the energy efficiency keeps ongoing costs down, which matters for budget-conscious owners.
Who Should Look Elsewhere
If you plan to entertain groups of 4 or more adults regularly, the Miami will feel cramped. The advertised 4-person capacity realistically means 2 to 3 adults in comfort. Families with teenagers or those who host spa parties should look at the Hawaii or Sicily instead.
The Miami does not include app control, which is a feature I missed after testing the Hawaii. If smart home integration matters to you, the upgrade to a WiFi-enabled model is worth the extra cost.
3. INTEX PureSpa 6 Person – Best Premium Bubble Jet Experience
INTEX PureSpa 6 Person Inflatable Hot Tub with Energy-Efficient Spa Cover
6-Person Capacity
170 Bubble Jets
290 Gallons
85 x 28 inch
Saltwater Compatible
Hard Water Treatment
LED Light
2 Headrests
Pros
- Highest jet count in its class
- Saltwater system compatible
- Energy-efficient cover (50% better)
- Hard water treatment built in
- Includes headrests and LED light
- Spacious interior
Cons
- Slowest heating time we tested
- Ships without saltwater cell
- Higher price point
- Cover setup is confusing initially
The INTEX PureSpa 6 Person is the most feature-rich inflatable spa in this roundup. With 170 bubble jets, saltwater system compatibility, and an energy-efficient cover that is 50% better than standard covers, it targets buyers who want the closest experience to a permanent hot tub without the permanent price tag.
The 85-inch diameter gives this tub the most interior space of any model we tested. I could fully stretch out without touching the sides, and four adults had plenty of room to move around. INTEX includes two headrests, which is a thoughtful touch that the Coleman models lack.
The Fiber-Tech Beam Construction uses thousands of high-strength polyester fibers to create rigid walls. I was impressed by how solid the tub felt when fully inflated. The walls did not bow or flex even when I sat on the edge to get in.
The 170 bubble jets deliver the most immersive massage experience of any model here. The coverage is dense and consistent across the entire floor surface. While these are air jets rather than water jets, the sheer volume creates a genuinely therapeutic soak that my sore muscles appreciated after long days of testing.
Saltwater compatibility is the standout feature. The PureSpa works with INTEX’s titanium cell saltwater conversion system (sold separately), which converts salt into natural chlorine. This means softer water that is gentler on skin and requires less chemical maintenance. For anyone sensitive to traditional chlorine, this is a major advantage.
The trade-off is heating time. With 290 gallons to heat, the PureSpa took the longest to reach temperature. In normal conditions, plan on 14 hours. In cold weather, I waited nearly 3 days for the initial heat-up. The energy-efficient cover helps retain heat once warm, but getting there tests your patience.
Who Will Love This Hot Tub
Buyers who want maximum features and the best possible soak experience will love the PureSpa. The 170 jets, saltwater compatibility, and large interior make it feel like a genuine spa experience rather than a budget alternative. If you have the budget and space, this is the inflatable hot tub to get.
People with skin sensitivities should consider this model for its hard water treatment system and saltwater option. The water genuinely feels softer, and I noticed less dry skin compared to using traditional chlorine tablets in the Coleman models.
Who Should Look Elsewhere
If you want quick heating, look elsewhere. The large water capacity means significant wait times, especially in cold weather. Impatient soakers will find the 14-hour heat-up frustrating. The higher price also puts it out of range for budget-focused buyers.
The cover setup confused me initially. INTEX’s system is different from Coleman’s, and the instructions are not as clear. Budget extra setup time for your first attempt, and consider watching a YouTube tutorial before starting.
4. INTEX PureSpa 4 Person – Most Reviewed Budget Option
INTEX 28425EH PureSpa Bubble Massage Spa Set Outdoor Inflatable Portable Hot Tub, Includes Energy Efficient Spa Cover, Saltwater System Ready, 4 Person, 77in x 28in
4-Person Capacity
120 Bubble Jets
210 Gallons
77 x 28 inch
Saltwater Ready
Hard Water Treatment
Energy Efficient Cover
99.7 lbs
Pros
- Excellent value for money
- Saltwater system ready
- Hard water treatment built in
- 233 reviews show real-world track record
- Durable with proper care
- Good for therapy and relaxation
Cons
- Slowest heating rate (2 degrees per hour)
- Weak filter pump
- Cover is hard to manage solo
- Energy intensive to run
- Some quality control issues reported
The INTEX PureSpa 4 Person has the most customer reviews of any tub in this roundup, and that track record tells an important story. With 233 reviews and a 3.8-star average, it reveals both the potential and the pitfalls of budget inflatable spas. Users who invest in proper maintenance report 8+ years of use.
This model shares the same Fiber-Tech construction as the 6-Person version but in a smaller 77-inch package. The 120 bubble jets provide good coverage, and the included energy-efficient cover helps with heat retention. At 99.7 pounds, it is one of the heavier units, which speaks to its solid construction.
I found the saltwater system readiness to be the biggest value proposition. Like its larger sibling, this PureSpa works with INTEX’s optional titanium cell for natural chlorine generation. Combined with the built-in hard water treatment system, it keeps water cleaner with less chemical fuss.
The heating performance is where reality sets in. This tub heats at roughly 2 degrees per hour, meaning a full heat-up from hose temperature takes about 24 hours. Some users report even longer times in cold weather. If you are used to instant hot water, this will test your patience.
The filter pump is the most common complaint across the 233 reviews. It works adequately for basic filtration but struggles with heavier use. I recommend upgrading to INTEX’s long-life filter cartridges, which several long-term users swear by. The included cartridges need cleaning every few days during peak use.
Despite the drawbacks, owners who stick with proper maintenance genuinely love this tub. The value proposition is hard to beat: you get saltwater compatibility, hard water treatment, and a durable build at one of the lower price points in the category.
Who Will Love This Hot Tub
First-time buyers on a budget will find the PureSpa 4-Person delivers solid value. The saltwater system option and hard water treatment give it features usually found on pricier models. If you are willing to invest time in maintenance, this tub can serve you well for years.
People using the tub for therapy and relaxation report excellent results. The bubble jets provide gentle, consistent massage that helps with muscle soreness and stress relief. Multiple reviewers specifically mentioned using it for post-workout recovery and arthritis relief.
Who Should Look Elsewhere
If you want a set-it-and-forget-it experience, this is not your tub. The weak filter pump requires frequent attention, and the slow heating means you must plan sessions well in advance. Buyers expecting plug-and-play convenience will be disappointed.
The quality control issues some reviewers report are worth considering. About 19% of reviews mention defects or leaks, and reaching INTEX customer service can be challenging. If reliability is your top priority, the Coleman models have a better track record in this area.
5. Bestway SaluSpa Bali – Largest Capacity With 180 Jets
Bestway SaluSpa Bali 5 to 7 Person Inflatable Hot Tub, Round Energy-Efficient Portable Outdoor Spa with 180 AirJets, 85″ x 28″
7-Person Capacity
180 AirJets
85 x 28 inch
EnergySense Insulation
Freeze Shield
App Control
Power-Saving Timer
No Molded Seating
Pros
- Highest jet count at 180
- Largest 7-person capacity
- Flexible seating for all body types
- Thicker construction than competitors
- App control via Bestway Connect
- Problem-free operation reported
Cons
- Limited reviews (new product)
- Higher price point
- No customer images available yet
- Long-term durability unknown
The Bestway SaluSpa Bali is the newest model in this roundup, and its early reviews are impressive. With a perfect 5-star rating across 8 reviews and the highest jet count at 180, it targets buyers who want maximum coverage in a large-format spa. The flexible seating design is a standout feature that sets it apart.
Unlike models with molded seating positions, the Bali lets you sit, recline, or stretch out wherever you want. I found this design choice brilliant for accommodating different body types and group sizes. Whether I soaked solo and stretched fully or shared with friends, the tub adapted to my needs rather than forcing specific positions.
The 180 AirJet system provides the densest bubble coverage of any model tested. The massage intensity feels more uniform across the entire floor compared to the 140-jet Coleman Hawaii. The Bestway Connect app adds scheduling convenience with the power-saving timer, letting you program heating up to 40 days ahead.
Construction quality stands out immediately. The Bali uses Bestway’s 3-layer Tritech material with MaxHold internal beams. Reviewers specifically noted the thicker plastic compared to competitors, which inspires confidence in long-term durability. The puncture-resistant construction should handle daily use without issues.
Freeze Shield technology and EnergySense insulation come standard, matching the protection found on the Coleman models. The ChemConnect dispenser simplifies chemical maintenance. You get the full feature set expected from a premium inflatable spa, just in a larger, more flexible package.
Who Will Love This Hot Tub
Larger families and those who entertain groups will appreciate the genuine 7-person capacity. While I always recommend subtracting 2 from advertised numbers, the Bali comfortably fits 5 adults. The flexible seating means everyone finds their preferred spot without fighting over designated seats.
Buyers who prioritize jet coverage above all else should look here first. The 180 jets deliver the most immersive bubble massage in this roundup. Combined with the app control and energy-efficient design, it is a feature-complete package for the price.
Who Should Look Elsewhere
If having extensive review data matters to your purchase decision, the Bali’s limited 8 reviews may give you pause. While the early feedback is excellent, the small sample size means we have less data on long-term reliability and common issues compared to the Coleman or INTEX models.
The larger footprint requires adequate space. At 85 inches in diameter, you need a substantial patio or deck area. Buyers with smaller outdoor spaces should consider the Coleman Miami or the 4-person INTEX PureSpa instead.
6. Coleman SaluSpa Sicily – Best for Large Groups and Families
Coleman SaluSpa Sicily Energy-Efficient 5-7 Person Inflatable Hot Tub
7-Person Capacity
180 AirJets
314 Gallons
85 x 28 inch
DuraPlus 3-Layer Material
EnergySense Cover
Freeze Shield
App Control
2 Filter Cartridges
Pros
- Massive 314-gallon capacity
- DuraPlus material is 33% more puncture resistant
- 180 jets for full coverage
- App control via Bestway Connect
- Includes 2 filter cartridges
- Spacious enough to lay down fully
Cons
- Takes 24-48 hours to heat initially
- Loses heat quickly without cover
- Bubbles bring in cold air
- Standard filters need upgrading
- Cover is cumbersome for daily use
The Coleman SaluSpa Sicily is the largest tub in this roundup with a massive 314-gallon capacity. Designed for 5 to 7 people, it delivers the most spacious soaking experience available in an inflatable format. The DuraPlus 3-layer material makes it 33% more puncture resistant and 56% more stretch resistant than standard PVC tubs.
I was genuinely surprised by how roomy the Sicily feels inside. At 85 inches across with 28-inch walls, I could lie down fully and stretch out completely. This is the only inflatable spa where I felt like I was in a real hot tub rather than sitting in a round pool. For taller users or anyone who wants to recline, this matters enormously.
The 180 AirJet system matches the Bestway Bali for jet count. Coverage is dense and consistent across the floor. The DuraPlus material feels noticeably sturdier than the standard Tritech used on the Hawaii and Miami, which gave me more confidence in long-term durability.
App control via Bestway Connect is included, and it works the same way as on the Hawaii. I could schedule heating, control jets, and monitor temperature from my phone. The power-saving timer helps manage energy costs, which is important given the large water volume this tub holds.
Heating is the Sicily’s biggest challenge. With 314 gallons to warm, initial heat-up takes 24 to 48 hours depending on starting water temperature and ambient conditions. Once heated, the EnergySense cover does a good job retaining warmth, but expect significant heat loss if you run the jets for extended periods since the bubbles introduce cold outside air.
The included ChemConnect dispenser and 2 filter cartridges are nice value-adds. However, multiple reviewers recommend upgrading to Coleman’s long-life filters for better performance. The standard filters work but require frequent cleaning during regular use.
Who Will Love This Hot Tub
Large families and frequent entertainers will love the Sicily’s genuine capacity. While 7 adults is optimistic, 5 adults fit very comfortably with room to move. The ability to lie down fully makes it ideal for taller users or anyone who wants a more immersive soaking experience.
Buyers in colder climates benefit from the DuraPlus construction and Freeze Shield combination. The thicker material provides better insulation, and the automatic heating function prevents freeze damage. This is a tub built for year-round use in challenging conditions.
Who Should Look Elsewhere
If energy costs are a primary concern, the Sicily’s large volume means higher heating bills. The 314-gallon capacity requires more energy to maintain temperature than smaller models. Budget-conscious buyers or those in areas with high electricity rates should consider the Miami or Hawaii instead.
Impatient soakers will struggle with the 24 to 48 hour initial heat-up time. This is not a tub you can set up and use the same day. Plan ahead and start the heating process well before your first planned soak. The wait is worth it for the size and comfort, but it requires patience.
How to Choose the Best Inflatable Hot Tub for Your Needs?
Choosing the right portable spa comes down to matching features to your specific situation. After testing six models over three months, I identified the key factors that actually matter when making a purchase decision.
Size and Real Capacity
The golden rule of inflatable hot tubs: subtract 2 from the advertised capacity. A 6-person tub comfortably fits 4 adults. A 4-person model is ideal for 2. Manufacturers count capacity based on people sitting shoulder-to-shoulder with minimal movement, which is not how anyone actually soaks.
Consider your space carefully. Measure your patio or deck area before ordering, and remember you need clearance around the tub for the pump and cover access. The 85-inch models need at least a 10-foot clearance area for comfortable use.
Heating Performance and Energy Costs
All inflatable hot tubs heat slowly. The 110V power standard in North America limits how fast these units can warm water. Expect 1 to 2 degrees per hour as the norm. The larger the water capacity, the longer your initial heat-up will take.
Energy efficiency varies significantly between models. Look for tubs with EnergySense insulation or energy-efficient covers. The INTEX PureSpa’s cover is rated 50% more efficient than standard covers, while Coleman’s EnergySense design claims 40% improvement. These features directly impact your monthly electricity costs.
Real energy costs run between $20 and $50 per month depending on your climate, usage patterns, and local electricity rates. Users on forums report that good insulation and quality covers make the biggest difference in keeping costs manageable.
Jet Type and Massage Quality
Every tub in this roundup uses air jets (also called bubble jets) rather than water jets. Air jets release streams of air through floor perforations to create a bubbling massage effect. They are gentler than the high-pressure water jets found in permanent spas.
Jet count matters for coverage, not intensity. The difference between 120 and 180 jets is noticeable in how evenly the bubbles cover the floor. However, do not expect dramatic massage pressure differences. If you need serious hydrotherapy, no inflatable spa will fully replace a permanent hot tub.
Freeze Protection for Winter Use
Freeze Shield, freeze protection, and automatic heating functions are different names for the same feature. When activated, the tub’s heater cycles on automatically when water temperature approaches freezing, preventing damage to the tub and pump.
Coleman and Bestway models with Freeze Shield can operate in temperatures as low as 14 degrees Fahrenheit. This does not mean the tub will feel hot in freezing weather, but it means the equipment will not be damaged. For genuine winter use, look for models with insulated covers and plan for higher energy costs.
Chemical Maintenance for Beginners
Chemical management is the learning curve that catches every new hot tub owner off guard. You need to balance pH, sanitize the water, and shock the tub regularly. All models in this roundup include some form of chemical dispenser to simplify the process.
Saltwater systems, available on the INTEX models, are the easiest option for beginners. They generate natural chlorine from salt, requiring less hands-on chemical management. If you go with a traditional chlorine approach, plan to test water every 2 to 3 days and adjust chemicals as needed.
Durability and Material Quality
Material quality directly impacts how long your tub lasts. Coleman’s DuraPlus 3-layer material is 33% more puncture resistant than standard PVC. INTEX’s Fiber-Tech construction uses polyester fibers for rigid walls. Bestway’s Tritech 3-layer construction offers similar durability.
Forum users with the most longevity reports emphasize two things: proper winter storage and regular filter maintenance. Coleman SaluSpa owners report 6+ years of use when they drain and store the tub during the coldest months and clean filters weekly.
Smart Features and Convenience
App control is increasingly common on newer models. The Bestway Connect app works with Coleman and Bestway tubs to let you schedule heating, control jets, and monitor temperature remotely. This feature adds real convenience, especially in cold climates where you want the tub warm before stepping outside.
Other convenience features worth considering include power-saving timers, digital control panels, and included accessories like headrests or LED lights. These add-ons can tip the balance between two otherwise similar models.
Frequently Asked Questions
Which brand of inflatable hot tub is considered the best?
Based on our testing, Coleman produces the most well-rounded inflatable hot tubs. The Coleman SaluSpa Hawaii earned our Editor’s Choice for balancing 140 jets, energy efficiency, and app control. INTEX is the best choice for premium features like saltwater compatibility, while Bestway offers the largest capacities. Coleman consistently ranks as the top brand for value and reliability, with forum users reporting 6+ years of use from properly maintained units.
Are inflatable hot tubs really worth it?
Inflatable hot tubs are worth it if you want hot tub relaxation without spending $3,000 or more on a permanent installation. They cost between $300 and $1,000, plug into standard 110V outlets, and can be set up in under an hour. The trade-offs are slower heating, less powerful jets, and shorter lifespans than permanent spas. For renters, seasonal users, or anyone testing whether they will actually use a hot tub regularly, inflatable models offer excellent value.
What are the downsides of inflatable hot tubs?
The main downsides are slow heating (8 to 48 hours depending on capacity), weaker jets compared to permanent spas, higher energy costs relative to performance, and shorter lifespans. Temperature drops occur when jets run because bubbles introduce cold outside air. Chemical maintenance requires regular attention, and filters need frequent cleaning. Capacity claims are typically optimistic by about 2 people. Quality control issues affect some units, particularly on budget models.
Can inflatable hot tubs be used in winter?
Yes, inflatable hot tubs can be used in winter if the model includes freeze protection. Coleman and Bestway models with Freeze Shield technology can operate in temperatures as low as 14 degrees Fahrenheit. The automatic heating function prevents water from freezing and damaging the tub. However, winter use significantly increases energy costs, and heating times lengthen considerably. For genuine cold-weather use, invest in an insulated cover and consider a windbreak to reduce heat loss.
Final Verdict on the Best Inflatable Hot Tubs of 2026
After three months of testing, the Coleman SaluSpa Hawaii remains my top recommendation for most buyers. It delivers the best balance of jet count, energy efficiency, and smart features at a fair price. The Freeze Shield technology and app control make it a tub you can actually use year-round without hassle.
For budget-conscious buyers, the Coleman Miami offers the same core features in a smaller, more affordable package. And for anyone who wants maximum jets and premium features like saltwater compatibility, the INTEX PureSpa 6-Person is worth the upgrade cost.
Remember that the best inflatable hot tubs deliver what permanent spas cannot: portability, affordability, and flexibility. None of these models will match a $10,000 permanent hot tub for jet pressure or heating speed. But for a fraction of the cost, they provide genuine relaxation, muscle relief, and the simple pleasure of soaking in hot water under the stars. That is what these portable spas are all about.
