Softub vs Intex: Foam-Shell Spa or Inflatable Bubbles in 2026?

Quick Answer: The Intex PureSpa Plus is an inflatable spa with 140 warm-air bubble jets for around $500-$600, built to set up in 20 minutes and drain away for winter. The Softub Sportster 140 is a semi-permanent, heat-welded 25-layer foam-shell spa with only 4 true water jets and no conventional water heater at all — a patented pump heat-recovery system warms the water instead — for $6,895-$8,995, a 13-18x premium. Buy Intex to test whether hot tub ownership is for you at low risk; buy Softub only if you already know you’ll soak daily for years and want a shell built to outlast several inflatables’ worth of ownership.

Intex and Softub sit at opposite ends of this site’s plug-and-play spectrum — one is the cheapest real way into a hot tub, the other is the most expensive single-model spa reviewed here — but the two have never been compared directly. This guide puts the two shell philosophies, jet types, and heating designs side by side. (For the full picture on each brand alone, see our best inflatable hot tub picks and Softub Sportster 140 review.)

Softub vs Intex by the numbers

• 4 true water jets on the Softub Sportster 140 versus 140 warm-air bubble jets on the Intex PureSpa Plus, per each brand’s own spec sheet — Intex wins on count, Softub wins on jet type.
• No conventional water heater on the Sportster — Softub’s own patent filings describe a heat-recovery duct around the pump motor that reclaims waste heat instead of running a resistive element — versus a dedicated electric heater on the PureSpa Plus, the same setup every other inflatable on this site uses.
• 25 layers of heat-welded polypropylene foam on the Sportster’s shell, a material Softub’s own FAQ traces to aviation insulation, versus Intex’s Fiber-Tech plus 3-ply laminated PVC inflatable bladder.
• $6,895-$8,995 vs. $500-$600 — a roughly 13-18x price gap, per authorized Softub dealer pricing and Intex retail listings as of October 2026.
• 115V/15A for Softub, 120V household outlet for Intex — neither needs 240V hardwiring or an electrician.

Head-to-head: foam shell vs inflatable bladder

Where Intex wins: price, setup speed, and seasonal storage

If the goal is finding out whether your household will actually use a hot tub before spending real money, Intex is the lower-risk way in. It costs a fraction of the Sportster’s price, needs no permanent outdoor spot, and can be drained and packed away if it turns out not to be for you. The tradeoff is jet type and a soft-sided wall that a foam shell doesn’t have to worry about the same way — see the numbers above.

Where Softub wins: shell durability and jet quality

If you’ve already decided a hot tub is a permanent, daily part of your routine, the Sportster trades jet count and fast heat-up for true water pressure and a shell engineered to outlast several inflatables’ worth of ownership. See our Softub Sportster 140 review for the full heat-recovery mechanics and who it actually fits.

What’s identical between the two

• No electrician required. Both the PureSpa Plus (120V) and the Sportster (115V/15A) run on a standard household-grade outlet — no NEC Article 680 disconnect, no 240V hardwiring, for either brand.
• Household plug-and-play class. Neither is a hardwired built-in spa; both are designed to be moved in by hand and plugged in.
• Core water-care routine. Both need the same chemicals — sanitizer, pH balancers, alkalinity, shock, test strips. See our hot tub chemicals guide for the full list.
• No independent third-party lifespan test. Neither brand publishes one; shell material and construction quality are the best proxies available for either.

How to choose

• Testing the waters on a budget? Buy the Intex PureSpa Plus — lowest commitment, lowest cost, easiest to drain and store if it doesn’t work out.
• Already know you’ll soak daily for years? Buy the Softub Sportster — the foam shell and true water jets are built for that use case, not occasional soaking.
• Renting, or short on permanent outdoor space? Intex — only one of the two you can realistically drain and pack away each season.
• Want real water jets without the Sportster’s full price? See our Lifesmart review or AquaRest hot tub guide for hard-shell spas with dedicated heaters in the $2,700-$3,600 range — a middle tier between these two extremes.
• Still comparing every major brand? See our best hot tub brands overview for how both stack up against Coleman/SaluSpa and the rest of the field.

The bottom line

Softub and Intex represent two genuinely different philosophies, not just two price points. Intex bets on low cost, fast setup, and a bladder you can drain away each winter; Softub bets on a heat-welded foam shell and a heat-recovery design with no conventional water heater, built for buyers who already know they’ll use it daily for years. Buy the Intex PureSpa Plus for a low-risk, affordable entry; buy the Softub Sportster 140 only once you’re certain a hot tub is a permanent fixture and the 13-18x premium buys decades of shell life you’ll actually use. Whichever you land on, the water-care routine is the same — and if you’ll be reordering filters or chemicals on repeat, see whether Amazon Prime is worth it for hot tub shoppers before you subscribe to anything.
