Blow-Up Hot Tub Buyer’s Guide
What to Know Before You Inflate Your New Favorite Addiction
Thinking about buying a blow-up hot tub? Good choice.
They’re affordable, portable, and ridiculously relaxing once you’re in one. But not all inflatable hot tubs are created equal — and if you go in blind, you might end up with a lukewarm, cramped bubble bucket that leaves you more stressed than when you got in.
So before you buy, here’s everything you actually need to know — minus the boring sales jargon.
First, What Is a Blow-Up Hot Tub, Really?
It’s exactly what it sounds like. An inflatable spa that you fill with water, plug in, and let heat up. Most have built-in bubble jets, some have massage systems, and the good ones feel like a real spa experience — just without the $10,000 price tag or a team of contractors in your backyard.
You fill it up, turn it on, and chill. That’s the magic.
How Many People Do You Actually Need It For?
Manufacturers love to say “4-6 people” — but that usually means 4 people sitting very close together, knees touching, regretting everything.
If it’s just for you and your partner? A 2–4 person tub is perfect.
If you’ve got kids, guests, or plan on inviting the whole neighbourhood? Go 6-person or larger. When in doubt, size up — no one ever complains about extra room in a hot tub.
Bubble Jets vs HydroJets — What’s the Difference?
This is a big one.
- Bubble jets shoot warm air through little holes all around the bottom of the tub. They feel great and sound like fizzy soda. Most inflatable hot tubs use this.
- Hydrojets shoot pressurized water, and feel more like an actual massage. They’re stronger, more expensive, and usually found on premium models.
If you’re just looking to relax and vibe: bubble jets are plenty.
If you want muscle relief after the gym or a long day: hydrojets are worth the splurge.
Heating Time & Temperature
Most blow-up tubs heat up to around 104°F (40°C) — that’s the sweet spot. But how long it takes depends on the model. Cheaper tubs might take 24+ hours to fully heat up. Good ones can do it overnight or faster.
If you live somewhere cold? Pay attention to insulation — otherwise the water will cool down faster than you can say “just five more minutes.”
Can You Use It in Winter?
Yes — if you get the right one. Some models are made for all-weather use, others are fair-weather friends.
Look for tubs with:
- Freeze protection (keeps the motor from dying in cold temps)
- Insulated covers
- Strong outer lining that won’t crack in frost
Also: don’t expect it to heat from scratch outside in a snowstorm. The trick? Set it up early and keep it running.
Power + Placement
Most inflatable tubs plug into a standard outdoor socket — no fancy wiring needed.
Just make sure the ground is level, solid, and can handle the weight (a full tub can weigh over a ton). Concrete patio = perfect. Deck = maybe. Grass = possible but not ideal long-term.
Also, make sure you’re near a hose. Filling one of these from the kitchen sink gets old fast.
Features That Actually Matter
You don’t need every bell and whistle — but a few extras make a big difference:
- Digital control panel (so you’re not guessing)
- Timer function (save electricity)
- Insulated lid (keeps heat in)
- Cup holders or trays (because drinks and tubs go hand-in-hand)
- Filter cartridges included (you will need these)
Price: What Should You Expect to Pay?
- Budget tubs: $250–$400 (basic bubbles, fewer features, slower heat time)
- Mid-range: $400–$700 (better jets, more comfort, faster heating, stronger insulation)
- Premium: $700–$1,200+ (hydrojets, rapid heating, reinforced walls, all-season use)
You don’t need to spend a grand to get a great tub — but if you’re serious about daily use or harsh weather, it’s worth the upgrade.
Final Word
A blow-up hot tub is one of the easiest ways to bring luxury to your life without going broke. But don’t just grab the first one with pretty pictures. Think about how you’ll use it, where it’s going, and how many people you’re sharing it with (or not — no judgment).
When you get the right one? Trust us… it’ll become your favorite place to be.
