It is the first question most buyers ask, and the honest answer starts with a gap: none of the makers on our site publishes a lifespan for its inflatable tubs. Anyone who quotes you a fixed number of years is guessing. What you can check is the guarantee, the build of the wall and the habits that shorten or stretch a tub's life.
The only number in writing: the guarantee
The guarantee is the one figure a maker stands behind. Here is what the listings show for the inflatables on our site.
| Brand | Inflatables we list | Maker's guarantee |
|---|---|---|
| Lay-Z-Spa | 12 | 2 years on every model |
| Wave | 2 | 2 years |
| Aoxun | 1 | 2 years |
| Intex | 4 | not published on the listing |
| Arebos | 1 | not published on the listing |
| Nordivale | 1 | not published on the listing |
| Canadian Spa Co. | 1 | not published on the listing |
A guarantee usually splits between the liner and the pump, so read the terms. Without a published guarantee you still have your rights under the Consumer Rights Act, but you have nothing extra from the maker. That is why our score gives a missing guarantee 0 points.
What wears out first
The pump and heater
The pump and heater unit works hardest. It runs for hours to heat the water, pushes air through the jets and sits outdoors. Hard water adds limescale to the heater element. Intex builds a hard water system into its PureSpa tubs; on other tubs, use a scale inhibitor in limescale areas.
Tubs with the heater built into the wall (the Lay-Z-Spa Rome, Aoxun 208 cm, Wave Atlantic 6 and others) keep the unit out of the rain a little better, but it is the same job.
The wall and seams
An inflatable wall flexes every time someone climbs in, and PVC goes stiff in the cold and soft in the sun. Seams are the weak point. Better walls spread the stress:
- Drop-stitch panels, as on the Lay-Z-Spa Helsinki, hold their shape with thousands of threads between the two skins.
- Beam construction, as on the Lay-Z-Spa Boracay (DuraPlus) and the Intex Fiber-Tech walls, uses internal supports.
- Plain triple-layer walls, as on the Lay-Z-Spa Miami (TriTech), are the simplest.
None of these makers publishes a test that shows how long each wall lasts, so treat the build as a sign of quality, not as a promise.
The cover
The lid takes rain, sun, snow and wind. When it splits or sags, heat loss goes up and debris gets in. Most makers sell replacement lids. See hot tub covers and heat loss.
The filter
Filter cartridges are a consumable, not a fault. You replace them when they stay grey after cleaning or the pleats tear. See how to clean a hot tub filter.
Habits that shorten a tub's life
- Setting it up on a rough surface. A stone or sharp edge under the floor wears a hole over time. Use a floor mat.
- Over-inflating on a hot day. Air expands in the sun. Check the pressure with the gauge or the maker's instructions, and let a little out if the wall is drum tight.
- Unbalanced water. Water with a pH out of range or too much sanitiser attacks the liner and the heater. Test it every couple of days. Our chemicals for beginners guide covers the basics.
- Freezing water in the pump. If the tub is off in a hard frost, water in the pipes and pump can freeze and crack them. Either keep it running with a frost mode (Wave lists FrostFree on its inflatables) or drain it fully.
- Packing it away wet. A damp, folded liner grows mould and the creases crack. Dry every part before storage.
- Leaving the lid unstrapped. Wind lifts an unstrapped lid, and a torn lid lets in leaves that clog the filter.
Habits that help
- Rinse the filter every few days of use and keep a spare.
- Drain, clean and refill on a regular schedule.
- Keep the lid on and strapped when you are not in the tub.
- Keep pets with claws out of it.
- Store it indoors, clean and dry, if you take it down for winter. Read using a hot tub in winter if you keep it up.
- Keep the receipt and the guarantee terms somewhere you can find them.
Is a foam or frame tub longer lived?
Again, nobody publishes lifespans. What we can say from the specs: foam-wall tubs do not rely on air pressure to hold their shape, and frame tubs have stiff panels. Both remove one of the inflatable's weak points. They also cost more, and the MSpa frame tubs on our site have no maker's guarantee on their listings. Compare the types in inflatable, foam or frame.
Quick answers
Can I patch a leak? Most inflatable tubs come with a repair kit. Small holes in the wall are often fixable. Leaks at a seam or at the pump connection are harder.
Can I buy a new pump for an old tub? Lay-Z-Spa and Intex sell spare parts. Check the part fits your model before you buy.
Does a dearer inflatable last longer? It often has a better wall and a heater in the wall, but the guarantee on Lay-Z-Spa tubs is 2 years whether you pay £299 or £1,219.
