The full picture
When you actually need room for a group, the PureSpa Plus 6-person is Intex's answer: a 77-inch round tub with a class-leading 170 bubble jets and 290 gallons of capacity. It heats to 104°F, uses Intex's Fiber-Tech 3-ply construction, and includes a genuinely useful extra — a built-in hard-water treatment system that helps protect the heater and improve water feel in hard-water areas. Controls are via a simple touch panel rather than an app. It's air-jet only like most of the category, but for larger households or entertaining, the extra seats and jet count make it the practical big-group pick without jumping to premium pricing.

The in-depth review
When you actually need room for a group, the PureSpa Plus 6-person is Intex's answer.
Room and jets
It's a 77-inch round tub with 290 gallons of capacity and a class-leading 170 bubble jets — the most in this lineup — heating to 104°F on Intex's Fiber-Tech 3-ply construction. It also includes a genuinely useful extra: a built-in hard-water treatment system that helps protect the heater from scale and softens the water feel, which matters a lot in hard-water areas.
The big-spa tradeoffs
All that water heats slowly and costs more to hold at temperature, so diligent cover use and a sheltered spot matter. It runs off a simple touch panel rather than an app, and it's air-jet only — no targeted HydroJets. Six adults is still cozy; for four it's spacious.

Frequently asked questions
Does it really fit six?
It’s one of the roomier inflatable tubs at 77 inches and 290 gallons, so it genuinely seats a group — though six adults is still cozy. For four it’s spacious.
What’s the hard-water treatment system?
A built-in feature that reduces water hardness as it circulates, which helps protect the heater from scale and makes the water feel softer — a real plus in hard-water regions.
Does it have an app?
No — it uses a straightforward touch control panel rather than smartphone control. If app scheduling matters to you, look at the Coleman Atlantis or a Bestway Smart Hub model.
How much does the big size cost to run?
More than a small tub — 290 gallons takes longer to heat and more energy to hold at temperature. Use the insulated cover diligently and keep it sheltered to control costs.
Air jets or water jets?
170 AirJets (air bubbles) — the most in this lineup for an all-over fizzy massage, but not the targeted pressure of HydroJets.
What maintenance does it need?
Balanced chlorine/bromine and pH, plus regular cartridge-filter changes. The larger water volume is a bit more forgiving on chemistry swings than a tiny tub, but filters still need frequent attention.
