Inflatable TentsInflatable SPAs: Built-in Pump & External Pump Hot Tubs
UNIFUN makes 13 inflatable hot tub models in round, square and octagonal shapes, holding 580 L to 1,380 L. Two platforms: laminated PVC tubs with a built-in pump, and laminated PVC, drop-stitch or PE foam tubs with an external pump. Most models are offered in EU (220–240 V) and US (110–120 V) electrics with EU, US, UK and AU plug options, and water temperature up to 42 °C (EU) or 40 °C (US).
Inflatable SPAs by Type
How Drop-Stitch Walls Work
Our external-pump hot tubs use drop-stitch walls (Double Wall Fabric): two PVC-coated layers joined by thousands of threads. When the wall is inflated, the threads pull tight and hold both surfaces flat, so the wall stays rigid and stable instead of bulging like a balloon. The same construction is used on our ice bath tubs, paddle boards and floating docks.

See drop-stitch hot tubsBuilt-in pump or external pump: which hot tub should I stock?
Built-in pump tubs put the pump, heater and controls in one unit: simple to set up and the best seller for home retail. External pump tubs keep the pump outside the wall, which makes service and replacement easier and suits rental and heavier use. Our external pump tubs come in laminated PVC, drop-stitch and PE foam wall constructions.
How many people does each size hold?
Inner diameter is the honest measure. Our tubs run from 115 cm square inside (580 L, compact) to 170 cm square inside (1,380 L, largest). Seating counts depend on how you market the tub, so we list inner size and water capacity for every model instead of a person count.
What about EU and US electrical requirements?
EU models run on 220–240 V 50 Hz at 1,540–2,040 W and heat up to 42 °C; US models run on 110–120 V 60 Hz at 1,380 W and heat up to 40 °C. EU, US, UK and AU plugs are available. Ask for the test report of the exact model and market before you order.
Inflatable SPAs FAQ
How many inflatable spas models do you make?
This page lists 5 product families with 13 sizes or items, all from our 2027 catalog.
Can you add my logo and custom packaging?
Yes. Logo, prints, colors and retail packaging can be customized on every model. Send artwork with your inquiry.
What is the MOQ?
MOQ depends on the model and on the customization. Send model numbers and quantities and we confirm MOQ in the quotation.
Are inflatable hot tubs worth it?
For many buyers, yes: they cost far less than an acrylic spa, need no permanent installation and can be stored off-season. The trade-offs are higher heating cost in cold weather and a less rigid wall. An insulated cover and a PE foam wall, as on our PE foam series, reduce heat loss.
Can you use an inflatable hot tub in winter?
Our hot tubs have an anti-freeze heating cycle that starts automatically to stop the water from freezing, plus an insulated lockable cover. Heating takes longer and costs more in cold weather; check the manual of each model for the lowest recommended outdoor temperature.
How hot does an inflatable hot tub get?
Our EU models heat up to 42 °C (108 °F) and our US models up to 40 °C (104 °F).
