Choosing an inflatable hot tub
Inflatable tubs differ in how the wall is built, how much insulation sits under and over the water, and whether the bubbles come from air or water jets. Those three things decide comfort and running cost more than the size on the box.
- Wall
- I-beam or drop-stitch
- Jets
- Air bubbles or water jets
Most tubs have an I-beam wall: internal ribs that hold the shape when inflated. Premium models use drop-stitch panels, thousands of threads between two layers, which stand firmer and feel more like a rigid tub.
AirJet tubs blow air through holes in the floor ring for an all-over fizz. HydroJet models push water through nozzles in the wall for a more directed massage, and some combine the two. Either way, the bubbles cool the water, so heaters often pause while they run.
Insulation matters for running cost: an insulated floor mat, a ground sheet and a thick, close-fitting thermal cover keep heat in. App control is handy for heating on a timer, but check what the app needs and whether the tub works without it.
Common mistakes
- Choosing by the bather number alone, without checking the inner seating space.
- Forgetting the floor insulation: much of the heat goes into a cold patio slab.
- Assuming the bubbles and the heater can run together on every model.
