Best Inflatable Hot Tubs
An inflatable hot tub is the cheap, no-install way into spa ownership: fill it, plug it in, and soak. The gap between a good one and a frustrating one comes down to heating, jets, and how it copes with cold. Here are the picks by category and what to check first.

Intex PureSpa Plus
Who it is for: Most buyers who want a reliable, comfortable soak with good build quality and easy controls.
- +Sturdier fiber-reinforced walls than basic inflatables.
- +Built-in hard water treatment and a clear control panel.
- +A well-supported line with parts and accessories easy to find.
Watch out: The bubble jets are relaxing but not powerful hydrotherapy. Like all inflatables, heating is slow in cold weather.
Bestway SaluSpa / Coleman SaluSpa
Who it is for: First-time buyers who want to try an inflatable spa without spending much.
- +Among the cheapest ways to get a real heated soak.
- +Quick to set up and simple to run.
- +Widely available, often as the Coleman-branded version of the same tub.
Watch out: Thinner build and a smaller heater, so it heats slowly and loses heat faster. Best in mild weather.
Intex or Bestway 6-person inflatable spa
Who it is for: Families or groups who want room for more than the usual four.
- +Fits five or six people for a social soak.
- +Same easy setup scaled up to a bigger shell.
- +More water means a more stable, comfortable temperature.
Watch out: More water takes much longer to heat and costs more to run. Make sure your spot and your electrical supply can handle it.
Insulated / higher-wattage inflatable spa
Who it is for: Anyone using the tub into late fall or winter, where basic models struggle.
- +Better insulation and a stronger heater hold temperature in the cold.
- +Some include a floor insulation pad to cut heat loss downward.
- +Less likely to give up on a freezing night.
Watch out: Even the best inflatable is not a hard-shell spa; in deep cold it works hard and costs more to run.
What actually matters when buying
Heating is the real limit. Inflatable hot tubs heat slowly, often 1 to 2 degrees per hour, and the heater usually cannot run at the same time as the jets. Plan to heat ahead of time, and know that cold weather and a bigger tub both stretch the wait. This is the number one thing people underestimate.
Insulation and a cover decide cold performance. Most heat escapes through the floor and the surface. A model with better wall insulation, plus a floor pad and a snug cover, holds temperature far better and costs less to run. In cold climates this is the difference between usable and frustrating.
Power and placement. Check the electrical requirement; some draw enough to want their own circuit. Set it on a firm, level surface that can hold the filled weight, which is considerable once water and people are in it. A floor pad protects the base and adds insulation.
It is still a chemically managed spa. An inflatable hot tub needs the same water care as any spa: sanitizer, balanced pH, and regular shocking. The small, hot, heavily used volume actually needs more attention than a pool, so factor in chemicals and testing, not just the tub.

Frequently asked questions
Are inflatable hot tubs any good?
For relaxing soaks at a low price with no installation, yes. They are comfortable and easy to set up. Their limits are slow heating, gentle bubble jets rather than strong hydrotherapy, and weaker performance in cold weather. For casual use they are genuinely good value; for powerful jets or year-round cold-climate use, a hard-shell spa is better.
How long does an inflatable hot tub take to heat?
Usually 1 to 2 degrees Fahrenheit per hour, so warming from cold tap water can take 12 to 24 hours. Heating is slower in cold weather and on bigger tubs, and most models cannot heat while the jets run. Plan to heat well ahead and keep the cover on between uses.
Do inflatable hot tubs need chemicals?
Yes, the same as any spa. You sanitize with chlorine or bromine, keep pH balanced, and shock regularly. The small, hot, heavily used water actually needs closer attention than a pool, so budget for test strips and chemicals along with the tub.
Can you use an inflatable hot tub in winter?
Some can, but basic models struggle in freezing weather, heating slowly and losing heat fast. If you want winter use, choose a better-insulated, higher-wattage model, add a floor insulation pad and a good cover, and expect higher running costs. Never let one freeze while empty or sitting unheated.
