Overview
An inflatable 6 person round hot tub with heated air bubble massage, an energy-efficient foam cover and a built-in hard water treatment system, sized 85 by 28 inches. It's aimed at backyard patio setups rather than a permanent built-in spa.
Intex leans on Fiber-Tech beam construction for the inflatable walls and pairs it with a thermal-resistant cover said to cut heat loss substantially between uses. The hard water treatment system and swappable S1 filter cartridges point to routine upkeep being part of ownership rather than optional, so anyone buying should plan for filter changes as a recurring task.
- 6 person capacity, 85 in x 28 in
- Heated air bubble massage system
- Energy-efficient thermal foam cover
- Built-in hard water treatment system
Who it's for
Fits a backyard or patio owner who wants a seasonal, take-down spa without a permanent installation or plumbing work. Not a fit for anyone expecting the shell rigidity or heat retention of a hard-sided hot tub.
Strengths and trade-offs
Drawn from this product's published specifications.
- Seats up to 6 without permanent installation
- Adjustable heated bubble massage
- Insulated cover to reduce heat loss between uses
- Built-in hard water treatment extends component life
- Inflatable construction won't match a hard-shell spa's rigidity
- Requires regular filter cartridge replacement
- No owner reviews yet to confirm real-world heat retention
Performance notes
Heated air bubbles circulate through the Fiber-Tech construction to warm and massage at the same time, with temperature adjustable to preference. The insulated cover and built-in hard water treatment system are meant to reduce heat loss and mineral buildup between uses, and the two S1 filter cartridges are accessed through an integrated control box for replacement.
