Small Hot Tubs: How Small Can You Actually Go?

People searching for the smallest hot tub are almost never asking about inches. They’re asking a harder question: “Will one actually fit my space, and will it still be worth sitting in?” Those are two different problems, and the second one is where most small-spa buyers get it wrong.

How Small a Hot Tub Actually Gets

Real numbers from spas on our floor in Apple Valley. A true small hot tub lands in the 76″–80″ long range, roughly 46″–60″ deep, and around 30″ tall. The smallest overall footprint isn’t square at all — it’s the round Softub Legend® 220 at 71″ across and 24″ tall.

Model	Footprint	Seats	Water	Power
Garden Spas Azalea	76″ × 46″ × 32″	2, face to face	170 gal	120V or 240V
Garden Spas Hibiscus	76″ × 58″ × 30″	2, side by side	185 gal	120V or 240V
Aquatic Spas Ella	80″ × 50″ × 30″	2 lounge, facing	175 gal	110V/20A or 220V/50A
Garden Spas Iris	78″ × 60″ × 30″	4 (bench + 2 buckets)	205 gal	120V or 240V
Softub Legend® 220	71″ round × 24″	2–4 adults	220 gal	120V / 15A

Notice the Azalea is the narrowest at 46″ deep, and the Softub is the lightest by a wide margin — 70 lbs for the tub shell versus roughly 400–500 lbs dry for an acrylic spa. Those two facts matter more than length when the problem is getting it into the space at all.

Measure the Path, Not Just the Patio

The patio almost always works. The route to it is what kills small-spa projects — a 36″ gate, a basement stairwell, a deck with a pergola over it, a side yard pinched by an A/C unit.

Measure the narrowest point of the whole path, not the destination. Acrylic spas go in on their side, flat, or however the access requires — so the dimension that has to clear is often the tub’s depth rather than its length. That’s why a 46″-deep Azalea gets into places a 60″-deep Iris never will, even though they’re nearly the same length.

The takeaway: if your tightest pinch point is under 40″, the Softub is usually the answer — it carries in as separate pieces, the heaviest being 70 lbs, and it rolls right into place. Otherwise you may be taking a fence section down for an afternoon, which is completely normal. See which spas fit through a 36″ doorway on their side.

The Question Nobody Asks: How Will the Two of You Sit?

With small hot tubs, size matters — but so does the environment you’re building. In a big spa nobody notices the seating geometry, because there’s a seat for every mood. In a two-person spa, the seating layout is the experience. Get it wrong and you’ve bought a very expensive misunderstanding.

There are really only four answers, and they’re all legitimate.

Facing each other — for talking

Garden Spas Azalea small hot tub with face-to-face seating for two

The Garden Spas Azalea puts two people across from each other in a 76″ × 46″ footprint. If the reason you want a hot tub is the conversation at the end of the day, this is the layout. It’s also the narrowest spa in the lineup, which is a useful coincidence.

Aquatic Spas Ella small hot tub with two ergonomic lounge seats facing each other

The Aquatic Spas Ella takes the same idea and reclines it — two ergonomic lounge seats facing each other, in 175 gallons. Same sociability, more stretch-out.

Side by side — for the view

Garden Spas Hibiscus small hot tub with side-by-side seating facing the same direction

The Garden Spas Hibiscus seats two people side by side, both looking the same direction. If there’s a lake, a treeline, a fire pit, or a TV on the wall of the porch, this is the one. Couples who want to watch something together consistently prefer it — and couples who want to talk consistently don’t. Worth knowing which one you are before you buy.

However you want — no fixed seats at all

Softub Legend 220 portable small hot tub with open sofa-style seating

The Softub Legend® 220 doesn’t commit you to a layout at all. It’s a 71″ round tub with 220 gallons and room for 2–4 adults, with no molded bucket seats dictating where you sit — you settle into it like a comfy sofa and sit however you want. It runs on a standard 120V 15-amp outlet, and the shell weighs 70 lbs, so it can move with you: to a different corner of the yard, or to a different house.

Four seats, still small — the popular compromise

Garden Spas Iris small hot tub seating four in a compact footprint

The Garden Spas Iris is the one people keep buying, and the reason is arithmetic: four seats — a bench plus two bucket seats — inside a 78″ × 60″ footprint. If the tub is mostly for two but occasionally for four, the Iris is usually the honest answer.

120V or 240V: What “Small” Really Costs to Run

Most small hot tubs can run either way, and the choice changes the ownership experience more than the purchase price does.

240V needs a dedicated circuit and a licensed electrician. It heats faster and holds temperature more comfortably through a Minnesota cold snap.

120V plugs into a standard outlet — no electrician, no permit, no trench. The trade is how a conventional plug-and-play spa has to budget that power. On low speed the jets filter and the heater runs. Switch to high speed for real massage therapy and the heater kicks out. In that moment you’re choosing between heat and therapy, which in January is a genuine limitation rather than a footnote.

The Softub exception: Softub runs a heat pump on a single-speed system, so it heats while you’re getting massage therapy — the only plug-and-play spa that does both, and it’s been doing it for 40 years. (Softub turns 40 in December 2026.) Running cost lands around $30 a month.

Rule of thumb: if the spa is going on a deck you’re renting, or you’re not ready for an electrician, start at 120V. If this is your house and your long-term backyard, run the 240V circuit while the pad is going in — it’s the cheapest it will ever be.

Small Hot Tub FAQs

The smallest footprint in the MinnSpas lineup is the Softub Legend® 220 at 71″ round and 24″ tall. Among acrylic spas, the Garden Spas Azalea is the most compact at 76″ × 46″ × 32″, seating two face to face in 170 gallons. Below that size you're generally looking at inflatable tubs rather than a permanent spa.

Often yes. Spas are delivered on their side, flat, or however the access requires, so the dimension that must clear is frequently the tub's depth rather than its length — a 46″-deep spa like the Azalea gets into far tighter spaces than a 60″-deep model. Measure the narrowest point along the entire route, not just the gate. For genuinely tight access the Softub is the reliable answer: it carries in as separate pieces with the heaviest at 70 lbs, and it rolls right into place.

Most small hot tubs seat two comfortably. A few seat more without growing much: the Garden Spas Iris fits four — a bench plus two bucket seats — in a 78″ × 60″ footprint, and the Softub Legend® 220 is rated 2–4 adults in a 71″ round shell. If the spa is mostly for two with occasional company, those are usually the better buys than a strict two-seater.

On a conventional 120V plug-and-play spa, not both at full output. Low speed runs the heater and filtration; switch the jets to high speed for massage therapy and the heater kicks out until you switch back. The Softub is the exception — it uses a heat pump on a single-speed system, so it delivers massage therapy while still heating. It's the only plug-and-play spa that does both, and it has worked that way for 40 years.

Size up only if you'll genuinely use the seats. The more common regret with small spas isn't too few seats — it's the wrong seating layout. Two people who wanted to talk end up in a side-by-side spa, or two people who wanted to watch the sunset end up facing each other. In a two-person spa the layout is the entire experience, so choose that first and the dimensions second.

Face-to-face seating, like the Garden Spas Azalea, puts two people across from each other — better for conversation. Side-by-side seating, like the Garden Spas Hibiscus, has both people looking the same direction — better when there's a view, a fire pit, or a screen to watch. The Aquatic Spas Ella gives you two reclined lounge seats facing each other, and the Softub Legend® 220 has no molded seats at all — you settle in like a comfy sofa and sit however you want.

Generally yes, because there is less water to heat — small spas here hold roughly 170–220 gallons versus 375+ in a large spa. A Softub Legend® 220 runs about $30 a month. Beyond gallons, running cost depends on cover quality, cabinet insulation, your electricity rate, and the temperature you hold, so ask us for the specifics on any model you're weighing rather than relying on a general rule.
