Here is the honest answer before you read another word: a six-person hot tub that plugs into a normal wall outlet and holds heat all winter does exist, and the Bestway SaluSpa Hawaii is the one to beat. It seats up to 8, fires 190 bubble jets, and runs on standard household power instead of a 240V hardwire job. The rest of this list splits into inflatable plug-and-play spas for patios and rentals, and hard-sided acrylic tubs you leave in place for a decade. What matters most is how many people actually fit when the bubbles are on, and how long the heater takes to claw its way to 104°F on a cold night.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Inflatable models warm roughly 1 to 3 degrees per hour and need a flat pad, while hardwired acrylic tubs heat faster and hold temperature far longer. The picks below cover every budget tier, so read on for the best 6 man hot tub that fits your yard, your power supply, and how you actually plan to use it.
Our Picks at a Glance
How To Choose The Best 6 Man Hot Tub
Buying a six-person hot tub is really two decisions stacked on top of each other: inflatable or hard-sided, and 120V outlet or 240V hardwire. Get those two right and the rest is details. Get them wrong and you end up with a tub that trips your breaker or takes three days to warm up in January.
Inflatable Or Hard-Sided
Inflatable tubs like the Bestway SaluSpa Hawaii and CO-Z models inflate in minutes, deflate for storage, and move with you when you relocate. The trade-off is heat loss through the soft walls, which is why insulated covers matter so much. Hard-sided acrylic tubs such as the Outback or Destination hold temperature better and give you real molded seating, but they weigh hundreds of pounds and stay where you put them.
What Your Outlet Can Actually Handle
A standard 120V household outlet can run most inflatable spas and a few hard-sided plug-and-play models, which is why they are so popular with renters. The Destination model runs on 240V hardwired power for efficiency, while the Outback plugs into a standard 120V/15A outlet with a GFCI cord included. Check your breaker before you buy anything hard-sided, because a dedicated circuit is often required.
Heating Speed And Real Capacity
Water warms gradually — some inflatable tubs climb about 1 to 3 degrees Fahrenheit per hour, so a cold fill can take a full day or more. Seating capacity is the other half of the puzzle: manufacturers count every body at the waterline, so a tub rated for 6 often feels best with 4 adults and a couple of kids. Measure your deck or patio first, because a square 73-inch tub and a round 85-inch tub leave very different footprints.

In‑Depth Reviews
1. Bestway SaluSpa Hawaii Energy-Efficient 6-8 Person Inflatable Hot Tub
Our pick — over 4★ from 70+ verified ratings; the strongest balance of quality and price.
Eight seats and 190 bubble jets on a standard household outlet.
If everyone in your house wants in at the same time, seating is the number that matters most. The Bestway SaluSpa Hawaii is the only tub on this list rated for 8 people, and it beats the CO-Z 6.5ft model on jets by a wide margin — 190 against 114, a difference of 76 jets you can feel across your shoulders. It measures 93 inches across in a round gray shape, with MaxHold internal fabric beams (built-in supports that hold the walls steady) and a 3-layer Tritech outer skin the maker describes as puncture- and damage-resistant.
What wins buyers over is the build quality, and the value lands right behind it. Buyers report the Bestway Hawaii inflating and filling quickly, with walls sturdy enough for a 180 lb person to sit on the edge. The air bubbles are weaker than the hydrotherapy jets in a hard-sided tub, but they still deliver enough pressure for a light massage. Owners mention the Bestway Hawaii climbing from 88°F to 102°F in about 10.5 hours in the shade and holding that temperature under its cover.
The trade-off you should know about is maintenance and sun exposure. Heat retention and inflation both draw mixed feedback — the tub deflates slightly when it is switched off and re-inflates once the jets run, which owners treat as a non-issue. One longer-term gripe is sun damage: baked-on grime coats the cover and walls after a season in direct sun, so a shaded spot or a fitted cover matters. The app controls temperature, timer, filter, and massage from your phone, and the Power-Saving Timer schedules the water up to 40 days ahead. Water heats to 104°F at the digital panel.
What Owners Rave About
- Eight-person seating — the widest capacity on this list
- 190 bubble jets, 76 more than the CO-Z model
- App control with a 40-day scheduling timer
- Wall thickness that holds up to a seated adult
What To Know Before Buying
- Air retention drifts when the tub is off, per several owners
- Sun exposure bakes grime onto the cover over time
- App pairing frustration turns up in a few reports
Best fit for: a large household that wants maximum seating and a smart, schedulable heater on standard household power.
Think twice if: the tub will sit in unshaded full sun and you would rather not fuss with cover care.
2. CO-Z 6.5ft Inflatable Hot Tub, 6-Person Outdoor Spa, 114 Air Jets & Heater
The gallon-heavy square spa that swallows six adults without a squeeze.
Water volume is where this one wins. The CO-Z holds 336 gallons against the LILYPELLE’s 240 — 40% more water to share among six people — and its footprint measures 78.7″ x 78.7″ x 25.6″ next to the LILYPELLE’s 73″ x 73″ x 25″. That extra interior space is the difference between everyone finding a spot and everyone playing footsie.
Six adults fit by the seating rating, and the square shape leaves more usable floor than a round tub of similar width. The 1350W heater climbs to 104°F, and customers note it warms faster than the manual suggests — roughly 12 hours from a cold fill to the point where it feels amazing to sit in. Reinforced puncture-resistant PVC wraps an aluminum insulation layer that holds warmth longer between soaks, and the whole package runs 59.5 pounds.
Here is the catch that shows up across owner experience: not every unit reaches the set temperature. Some owners ran it at 100°F and watched the water stall around 95°F, and a few never saw 104°F at all. That makes this a strong pick for warmer climates or an enclosed space where the ambient air is already mild, and a harder sell for cold-weather setups. The control panel handles temperature and bubbles, the included electric pump inflates it fast, and filter cartridges and a built-in drain system come in the box.
Room-per-person champion: at 336 gallons this beats the LILYPELLE’s 240 by a margin you feel the moment the sixth person steps in, and the square footprint uses patio space more efficiently than the round tubs.
The honest limit: the heater disappoints in cold weather — a recurring pattern in owner feedback is water that plateaus short of the set temperature. A foam pad underneath, as several owners suggest, helps.
Pick this one if: you want the roomiest inflatable in the sub-mid range and you live somewhere the nights stay mild.
Pass it over when: you need reliable heat in freezing air or a tub that hits its target temp every session.
3. LILYPELLE 4-6 Person Inflatable Hot Tub, Square Large Portable Spa
A square 73-inch spa built to tuck into a patio corner.
The compact square that works when every inch of patio counts. At 73″L x 73″W x 25″, the LILYPELLE is the smaller tub beside the CO-Z’s 78.7″ x 78.7″ x 25.6″ frame, and owners describe it as very roomy for the footprint. Six adults fit by the rating, and the flat square floor leaves a usable shape once four or five people are inside.
Heating is where this tub shows its trade-off. A PTC (positive temperature coefficient, a self-regulating heater element that gets more efficient as it warms) 1350W pump raises water from 68°F to 104°F at a rate of 1.8 to 3.6°F per hour, so a full fill can take the better part of two days. Once the water hits your target, a thermostatic system holds it there, and the included cover keeps that heat in. Two replaceable filter cartridges catch sand, debris, and hair, and the control panel flashes an alarm when the filter needs swapping — roughly every 120 hours of use.
What makes the slower warm-up worth it: the water stays warm once it gets there. Reviewers point out steady heat retention, and the durable PVC outer shell holds up over repeated use with good puncture and tear resistance. The build folds and deflates in minutes for storage, and the package includes a floor mat, cover, inflatable hose, three connection tubes, four filter cartridges, two filter covers, and two repair kits. This square sits in the mid range and lands near the CO-Z on price, so the choice depends on if you want maximum water volume or a tidier footprint.
Where it earns its keep: compact size plus zero fuss on maintenance once you learn the filter cycle — owners end up trusting it to hold temperature overnight in warm regions.
The one habit to build: budget a couple of days for the first fill, because the PTC heater warms the water gradually by design.
Great match for: a small patio or side yard where a 73-inch square slots in better than a wide round tub.
Skip the shortcut: if you want hot water the same evening you fill it, plan around the warm-up time or look at the faster hard-sided models.
4. UHOMEPRO Inflatable Hot Tub Spa Set, Outdoor Bubble Massage, 130 Jets
Two covers, a child lock, and a tub that fits four adults with room left.
For homes with small kids, the safety setup is the headline. The UHOMEPRO ships with two covers — an inflatable one that speeds heating and keeps out debris, and a heat-retaining one with a child safety lock that holds temperature and keeps curious hands out. That is a thoughtful pairing at a mid-range price, and the tub itself measures 73″L x 73″W x 26″H with an inner floor of 57″ x 57″.
Six adults fit by the seating rating, though the practical number is about four comfortably. The built-in heater, blower, and filter all live inside the liner, so there is no separate equipment box to hide on the patio — buyers consistently single out this layout for looking cleaner and being easier to clean up. The 130 air jets run off a 600W bubble motor, and the laminated PVC shell is built for long-term durability.
The one thing you will notice first is the warm-up. Water heats gradually by design, and the manual suggests preheating well ahead of when you plan to use it. Buyers describe it as serving its purpose nicely once it reaches temperature, but this is not a tub you fill and hop into twenty minutes later. The accessory kit is complete — high-quality filters, an inflatable hose, a PE ground mat, and a storage bag — so nothing extra is needed on day one.
Why families gravitate to it: the child-lock cover and all-in-one design mean the tub looks and stays tidy, and four adults sit with space to spare.
Set expectations on heat: a gradual heater plus a mid-range price tag means you buy this for convenience and safety over fast heating.
The right call if: young children share the yard, or you want the filters and heater tucked inside the tub instead of parked beside it.
Look elsewhere if: fast warm-up is your top priority over safety and a clean footprint.
5. 82″ Inflatable Hot Tub 4-6 Person, Round Outdoor Spa, Black
An 82-inch round tub with a 264-gallon fill and room to sprawl.
A wide round spa that trades the square’s corners for elbow room. The SunSwell-built 82″ tub holds 264 gallons, measures 82″L x 82″W x 25.6″H, and seats 4 to 6 people thanks to the generous circular basin. The round shape means every seat has the same view and the same share of the bubbles, which is why so many patios end up pairing it with a set of drink holders and call it done.
Heating is the standout on this one. Shoppers say the 82-inch round tub climbing from 76°F to 106°F in about 3 hours with the insulated cover on. The cover retains heat through the built-in insulation, and the child-safety lock keeps it secured, while GFCI protection (a ground-fault circuit interrupter that cuts power if current leaks, standard safety gear for anything electrical near water) backs the electrics. A 600W motor drives the 130 bubble jets, and the laminated PVC shell holds shape and resists punctures over long use.
The trade-off to weigh: heater reliability. A few units arrive with a dead heater inside the first few days, and the fix means a return and prepaid label negotiation. That is not the norm for most owners, but it is worth knowing this model has a warranty-claim path if it happens. The built-in removable filtration system keeps the water clean with minimal effort.
The reason owners keep it: at 3 hours from cold to 106°F this warms noticeably faster than most 120V inflatables on this list, and the round 82-inch basin seats six without crowding.
Worth knowing: a small share of units arrive with a heater fault, so check the water is warming on day one rather than week two.
Best for: the buyer whose top gripe with inflatable spas is the wait for warm water — this is one of the quickest on the list.
One caution before you buy: inspect the heater on arrival, since a rare faulty unit is easier to exchange than to repair later.
6. INTEX SimpleSpa 6 Person Inflatable Hot Tub, Portable Spa with 140 Jets
An 85-inch round spa with 140 jets and a built-in hard water system.
When you want the biggest round basin in the inflatable class, this is the one. Seating capacity is 6, and owners describe four large adults or six smaller ones fitting without shoulder collision.
The maintenance side of the design is the standout feature. INTEX builds in a Hard Water Treatment System that reduces harsh mineral buildup so the water stays softer and the spa lasts longer, and the horizontal beam construction paired with a mesh exterior resists punctures and abrasions. The included insulated ground cloth and insulated spa cover slow heat loss between sessions, and the integrated control box makes swapping the S1 type filter cartridges easy — two are included.
What dampens the value story: cost-effectiveness draws mixed feedback, with some owners feeling the ongoing electricity and chemical costs add up faster than expected. Heat retention earns positive notes though, with temperatures holding at 104 degrees in lower weather once the cover is on. Heated air bubble technology lets you adjust the warmth to preference, and buyers consistently call the mesh exterior tough enough to stay inflated through a full year without leaks.
Biggest bang for floor space: at 85 inches round and 290 gallons, this is the largest seating footprint among the inflatables here, and the mesh outer shell earns trust for holding air.
One cost to plan for: owners flag that running costs can outpace expectations, so budget the electricity and chemical upkeep rather than just the fill cost.
Worth choosing when: you have the patio width for an 85-inch round tub and you want built-in hard water treatment for smoother water.
Better to skip if: your electric bill is already tight and you want the lowest running cost on the list.
7. Coleman SaluSpa AirJet 7 Person Inflatable Hot Tub, 180 Soothing AirJets
Seven seats, 180 jets, and a design built to keep the pump from freezing.
If your guest list is longer than six, this is one of two tubs here rated for seven. The Coleman SaluSpa Sicily measures 85.04″L x 85.04″W x 27.95″H and holds 314 gallons, with the seventh seat pushing the basin wider than the 82-inch round tub above. The 180 AirJets fall short of the Bestway Hawaii’s 190, but they top the round 82-inch model’s 130 by a clear margin.
What earns the most appreciation is how it looks and how easily it assembles. Owners describe a sturdy, well-proportioned spa that fits four full-grown adults without crowding, with the 27.95-inch wall height making it easy to step over. Freeze Shield Technology is built in — the pump cycles automatically to keep the inner components from freezing, so a cold snap does not strand you — and the reinforced cover doubles as a debris barrier. A ChemConnect dispenser meters chlorine evenly, the pump and filter cartridge are included, and 2 easy-lift handles make repositioning it simple.
The pattern buyers learn over time is that the pump and heating deserve attention. Some units fail to push past 82°F, and a few buyers report the pump stopping after a month of use; the seller responds to warranty claims, and owners who bought an extended warranty had pump and cover issues resolved with a replacement unit later. The lesson is to treat the pump as the wearable part and protect it. Note too that this model is not sold in several states including CA, OR, NY, and WA, so check availability before you commit.
Why It Earns A Spot
- Seven-person seating — one of only two tubs here that fit it
- 180 AirJets, comfortably ahead of the 130-jet round model
- Freeze Shield auto-heating protects the pump in cold spells
- ChemConnect dispenser and reinforced cover included
What You Should Weigh
- Pump and heating speed draw mixed owner feedback
- Slower warm-up in cold climates
- Restricted sale in several states
- Warranty coverage on the pump runs short
Reach for this if: you need seven seats and want built-in freeze protection for shoulder-season use.
Move on if: your state restricts the sale or you want faster heating than the mixed reports suggest.
8. Coleman SaluSpa Hawaii Energy-Efficient 4-6 Person Inflatable Hot Tub
App-controlled AirJet spa that inflates in about a minute from its attached hose.
This is the tub for the person who wants to warm the water from the couch. The Coleman SaluSpa Hawaii runs 140 bubble jets, seats up to 6, and pairs with the Bestway Connect app so temperature, timer, filter, and massage are all a tap away. The Power-Saving Timer schedules the water up to 40 days in advance, which is genuinely useful for keeping a soak ready without running the heater around the clock.
At 71″L x 71″W x 28″H and 222 gallons, this is the most compact six-seater on the list — noticeably smaller than the 85-inch SimpleSpa. The walls and cover are built to hold heat, the MaxHold internal beams keep the whole thing rigid, and the 3-layer Tritech outer layer resists punctures. Owners mention the Coleman Hawaii inflating in roughly a minute from its attached hose, and one long-time owner calls it quick to set up, good at holding heat in cold weather, and tough enough to shrug off a cat’s claws.
The honest counterpoint is the app itself. A recurring complaint is pairing trouble that leaves the spa stuck cold, and one owner’s frustration with the app dropping the heating timer landed hard enough to send the tub back. Temperature control and air retention also draw mixed notes: some owners find the heat holds beautifully while a few report it staying cool or needing a daily top-up of air. Freeze Shield automatic heating protects the pump and liner in cold weather, and the digital panel heats water to 104°F. All told, the audience that leans on the phone controls will be the happiest here.
Smart-home crowdpick: the 40-day scheduling timer and one-minute inflation make this the easiest tub to live with in this size class, and the 28-inch wall height helps shorter bathers step in.
The thing to test first: connect the app on day one — the pairing step is a known friction point, and getting it settled before you fill keeps a cold tub from becoming your problem.
Ideal for: a tech-tilted household that wants to schedule and control the soak from a phone.
Not the one if: a stubborn app connection would ruin the experience, or six people want maximum legroom.
9. INTEX 28427EH PureSpa Bubble Massage Spa Set, 6 Person
A Fiber-Tech beam spa built to run on saltwater and hold temperature through winter.
Saltwater-compatible spas are a narrow niche, and this INTEX PureSpa is the six-seater that plays in it. Owners who prefer softer, salt-tended water keep coming back to this one for the combination of Fiber-Tech beam construction — a structural frame that keeps the walls true without the wobble of a basic inflatable — and the fact that it can be fitted with a saltwater system down the line.
The heating side is genuinely impressive for the price band. A PTC heater boost heat transfer, and the high-density thermal-resistant foam cover boosts energy efficiency, holding a consistent 104 degrees with a rise of about 1 degree per hour. Customers note it holding 104°F through Midwest winters, even in below-zero windchill. That performance is the reason the tub still earns space on the list despite the mixed notes on functionality and cost.
Where you feel the compromise: the tub runs on a constant cycle to hold temperature, so the electricity draw is real, and the filter pump and bubble jets sit on the weaker side of the class. Air retention and leakage show up as the top complaints in owner data — cuts on arrival turn into slow leaks that owners have to chase. INTEX backs it with responsive support, and a missing inlet or outlet fitting typically gets resolved quickly. Full fill takes about 90 minutes with a tankless heater, and the tub seats about four comfortably in practice.
Winter performer: a foam cover plus PTC heating keep this tub at 104 degrees through genuine cold, and the saltwater-ready plumbing is a hard feature to source elsewhere at this level.
What it will cost to own: expect a running heater and a weaker filter — owners resolve this by upgrading filtration and adding insulation, but it is maintenance to plan for.
For the buyer who wants: year-round use and a path to saltwater sanitation, with winter-weather heat retention that holds up.
Not for the buyer who wants: maximum jet strength or a tub that stays off the outlet between soaks.
10. Outback Hot Tub, Fits 6 People, 20 Massage Jets, by Strong Spas
The first hard-sided step up: resin shell, 20 hydrotherapy jets, standard outlet.
This is where the category shifts from inflatable to permanent. The Outback is a hard-sided acrylic-style tub with a durable resin shell — impact-resistant and low-maintenance, with a cobblestone finish you can leave outside year-round without the cover-and-wall fuss of an inflatable. Seating is 5 to 6 in contour-style seats, and the basin holds 300 gallons within an 80.5″L x 80.5″W x 35.5″H frame.
The signature feature is the plug-and-play power setup. The Outback runs on any standard 120V/15A outlet with a GFCI cord included, so no electrician is needed to bring it online — a real advantage over hardwired tubs. Owners confirm the Outback holds heat below freezing on 120V and recovers to 104°F overnight. A 2 peak HP, 2-speed pump circulates the water efficiently and the 20 hydrotherapy jets deliver deeper pressure than any air-bubble inflatable, which is the reason buyers graduate to this model in the first place.
The recurring caveat is heating speed and the deep entry. Heating time draws mixed notes — some say fast, some say slow — and the 35.5-inch wall height makes the tub harder to climb into, so owners often recommend steps. The interior finish on some units shows minor flaws that owners remedy or accept, and one unit’s pump died after a year and a half of light use under a one-year warranty. That is the exception rather than the rule, and most reviewers point out five months or more of daily use with no failure at all.
Why Hard-Sided Wins Here
- 20 hydrotherapy jets that hit far deeper than air bubbles
- Runs on standard 120V/15A with GFCI cord included
- Resin shell shrugs off weather without special care
- Holds 104°F below freezing in owner experience
Real-World Caveats
- Heating speed gets mixed owner feedback
- 35.5-inch wall makes entry harder — steps recommended
- One-year warranty on the pump is short
- Blemishes and one unit’s pump failure show up in long-term feedback
Best for: the buyer who wants hard-sided jets and real seating without hiring an electrician.
Watch out if: a tall wall makes entry tricky or you want the fastest heat-up and top-tier warranty coverage.
11. Destination Outdoor Hot Tub, 6-Person 59-Jet with Waterfall Arch and Bluetooth Stereo
The full hardwired spa: 59 stainless jets, a waterfall arch, and a Bluetooth stereo.
For a permanent backyard build with full amenities, nothing else on this list matches the Destination. It is the only model here with a 240V hardwired power source for energy-efficient operation, 59 stainless steel adjustable jets pushing 80 streams of water, and a Bluetooth stereo paired with a waterfall arch for atmosphere. Seating is up to 6 in comfortable upright positions across a range of jet patterns, all inside an acrylic shell — a fiberglass-reinforced plastic that holds heat and holds its finish for years.
The owner experience around reliability is reassuring at this price point. Multiple owners describe the dual-pump system — a dedicated filtration-and-heating pump plus two 3hp circulation pumps — as flawless, with one owner noting customer service replaced a loose jet core within days. Heat retention is solid across reports, with owners saying temperature never drops once set, and the setup is smooth when the tub arrives on a proper pad. Functionality earns the strongest feedback, with owners calling it a high-end-features, low-price purchase they would absolutely rebuy.
The honest friction points are logistics and packaging details. At 974 pounds the tub needs real planning before delivery — several buyers ended up paying movers to get it through a narrow gate. A few report the cover arriving wrong or oversized with clasps that break, and one owner found that raising the temperature requires power-cycling the tub each time. There is also the requirement to install water chemistry, filters, and pH maintenance from day one. If those logistics are not a dealbreaker, this is the soaker that feels like a real backyard build.
Where the value lives: 59 jets, a waterfall arch, and Bluetooth in a six-seat acrylic tub running on 240V efficiency — the amenity list is class-leading among the picks here.
The planning phase: at 974 lb this is a two-mover job through any narrow gate, and buyers should expect to sort delivery logistics themselves before the tub lands.
Buy this when: you are ready to hardwire 240V and you want a full-featured tub you never have to move again.
Not for you if: you need portability or you would rather not manage water chemistry and 240V electrical work as part of setup.
Understanding the Specs
Seating Capacity Ratings
Manufacturers count every bather at the waterline, so a “6-person” rating includes people sitting shoulder to shoulder with no room to move. In practice, most owners find a tub rated for 6 seats about 4 adults comfortably, and a tub rated for 8 seats 5 or 6. If your household regularly fills every seat, size up one tier rather than buying exactly at your headcount.
Fill Volume And Warm-Up Time
Water capacity in gallons tells you two things at once: how much heat the tub has to build and how much it can hold. A 336-gallon basin takes longer to reach temperature than a 210-gallon one, because there is more water to warm. Inflatable heaters typically raise water 1 to 3 degrees Fahrenheit per hour, while a well-insulated hard-sided tub on 240V heats faster and holds heat far longer between sessions.
Air Jets Versus Hydrotherapy Jets
Air jets push bubbles through holes in the floor and walls of an inflatable, driven by a blower motor rated in watts. They feel like a light full-body massage. Hydrotherapy jets, found in hard-sided tubs, push a focused stream of water under pressure and hit much deeper into muscle. A tub with 190 air jets is not the same as a tub with 59 hydrotherapy jets — the two counts are not comparable and the sensation is different.
120V Versus 240V Power
A 120V hot tub plugs into a standard household outlet, which is what makes inflatables and plug-and-play models so easy to install. A 240V tub needs dedicated hardwiring and often a GFCI breaker, but it heats faster and runs more efficiently over time. Because heating is the biggest draw, most owners on 120V add an insulated cover and a foam pad underneath to slow heat loss and cut the power bill.

Final Thoughts: The Verdict
For most buyers, the best 6 man hot tub winner is the Bestway SaluSpa Hawaii Energy-Efficient 6-8 Person Inflatable Hot Tub because it seats eight, fires 190 bubble jets, and runs on standard household power with app control and a 40-day scheduling timer. If you want a compact square spa that slots into a small patio and holds heat beautifully once filled, grab the LILYPELLE 4-6 Person Inflatable Hot Tub. And for a hard-sided step up with deep hydrotherapy jets on standard 120V, the Outback Hot Tub by Strong Spas is the one to reach for.
Whichever way you go, size your tub to the people you actually expect in it. Almost every pick here is rated for one more body than it seats comfortably, so a 6-person tub means four adults and space to stretch. Get the seating, the power setup, and the warm-up time right before the first fill, and you will spend a lot more evenings soaking and a lot fewer chasing a cold tub.
