Just like other inflatable products, an inflatable hot tub is prone to punctures. Therefore, you need to be prepared for it when it happens.

All you need is an appropriate inflatable hot tub repair kit. It is easy to fix whether you need a quick fix or a long-term solution. The kits will save you money and time compared to getting expert assistance for the hot tub repair service. You’ll be able to jump back into your hot tub in no time at all.

A puncture in an inflatable hot tub can be disastrous. If left unattended for any length of time, it may grow larger, making it much more difficult or impossible to mend. It is, therefore, recommendable to fix it as soon as you realize it is there.

Holes limit the use of an inflatable hot tub for relaxation; thus, they should be smoothly covered by sticking a self-adhesive patch, applying glue on non-adhesive patches, or wrapping a tape while ensuring no water or air bubbles are forming underneath to achieve an airtight seal. The seal should then be left to dry before the hot tub is used again.

How To Repair a Puncture on An Inflatable Hot Tub?

First of all, identify the air leak in the inflatable hot tub.

Find if the leak is above or underwater by spraying the area in portions using soapy water while keeping an eye out for bubbles or checking into the water for bubbles. If the bubbles are evident, then there is a hole in the body of the hot tub.

Then, place a finger over the hole until it stops bubbling and mark using a waterproof marker pen. Clean the air leak area and make sure it has no debris, grease, or anything else to prevent the patch from attaching correctly. Then allow it to dry.

Lastly, fix the puncture with an appropriate inflatable hot tub repair kit. The right hot tub repair kit to be used depends on the material of the hot tub, size, and type of puncture.

Cut the patch into the required size while allowing one inch around the puncture to allow enough area for an airtight seal.

Peel off the back of the self-adhesive patch or apply some adhesive on the back of the patch, then stick it over the marked hole while applying pressure to ensure no water or air bubbles form underneath.

Hold it in place for few minutes, then let it dry for at least 2 hours. For best results, wait for at least 24 to 36 hours before inflating it back. Once repaired, fill the hot tub with air until the pressure reaches its maximum and double-check your repairs to ensure no leaks.

Key point: Various repair kits have different ways of applying them; therefore, it’s best to read the instructions on the manual first to make sure you choose the appropriate kit and evade more damage.

Why Do Inflatable Hot Tubs Get Punctured?

There are numerous reasons why your inflatable hot tub might get punctures. Some of the main ones include.

  • Inflatable hot tubs are prone to damages due to sharp objects that pinch through the outer body of the hot tub
  • The age of the hot tub (the older it gets, the more likely punctures to occur);
  • High rate of usage, and
  • Poor maintenance also increase the probability of holes developing.

What Are the Types of Inflatable Hot Tub Punctures?

A puncture may occur inside the hot tub under the waterline or on the hot tub’s interior wall above the waterline or the exterior wall. A hole above the water level is easier to repair as one doesn’t need to empty the hot tub to fix it.

How To Detect a Leak On An Inflatable Hot Tub?

First and foremost, fill the hot tub to the recommended level.

Leave it for few hours, then check if the walls are hard or soft. If hardened, then there is a puncture. This could be due to the vinyl’s expansion and contraction or that it just lost air over time.

If softer, then there is a crack that should be mended quickly.

The first step is to make sure that it is not the valve leaking. If the leak appears to come from the valve, then tighten it; it could have gotten loose due to the constant ins and outs of frequent use. However, if the valve and the seal are tight but there are leaks, there is a hole.

For underwater holes, turn off the jets in the hot tub and let the water settle for a few minutes before looking for the bubbles inside the walls, whereas for outer wall fractures, spray on the vinyl in parts with soapy water and watch for any bubbles that form as the mixture lands on the surface.

If you notice bubbles, place your finger over the hole until the bubbles stop, then pinpoint the hole area.

How To Determine Whether the Puncture Has Been Repaired?

Inflate the hot tub to the maximum, then check for any bubbles to determine if the puncture has been sealed. If there are no bubbles at the patch’s edge, the leak has been successfully repaired; otherwise, the repair has failed. 

Probably less solvent was used, or the patch was too small for the hole. Redo the process and cover the previous patch’s edges to prevent corners lifting or hiring a professional.


Before repairing a puncture, one should examine if fixing it is more costly than replacing it. It is not worth repairing if expensive, but if cheap, then the appropriate repair kit can seal the leak and restore the inflatable hot tub.  

The brand of an inflatable hot tub and proper maintenance are major determinants of its lifespan. Therefore, how an inflatable hot tub is well cared for determines its longevity.

Damage to the hot tub should be prevented by ensuring sharp objects, twigs, stones, leaves, or anything that might pierce or scratch the vinyl isn’t kept too close. Punctures can also be reduced through regular cleaning to remove harmful items and the use of a floor protector that insulates and protects the hot tub. The inflatable hot tub should also be covered once used.
