Adding enough salt to reach 2,000-3,000 ppm in your spa takes about 2 lbs. per 100 gallons of water. The mineral in the water raises the buffering capacity of the water to resist changes in pH, alkalinity and calcium hardness levels. The addition of salt increases the total dissolved solids of the water, making the water less aggressive and more resistant to water balance fluctuations.
Thanks to its low-profile design, this particular tub can be set up in just a matter of minutes. This being said, you will be surprised to find out that it can accommodate up to four adults at the same time despite its apparently lightweight construction. As far as features go, this inflatable hot tub comes with a Lay-Z massage system, both rapid-heating and water-filtration systems, and an easy to operate digital control panel to top it off. Overall, it is perhaps one of the most cost-effective inflatable hot tubs money can buy.
Maybe the best benefit of a saltwater hot tub is that you no longer need to store bromine or chlorine tablets. You should still shock the spa, so keep a granular oxidizer on hand, but you can use chlorine-free MPS if you prefer. Spa salt systems make their own chlorine, so it’s still a chlorinated spa. However, the chlorine is created naturally, without binders or additives. It’s pure chlorine.
If you want to make full use of your hot tub experience, make sure to purchase hot tub accessories like glass holders, headrests, inflatable benches, extra filter cartridges, pool/tub sponges, and spa seats. These accessories are not included in a basic inflatable hot tub setup. Spare parts and accessories can also be purchased from After Sales suppliers or from your hot tub’s manufacturer.

Instead of using real water jets, they use air jets that blow the air around in the tub. This causes the water to cool down a lot faster than it would if you were to use a hard side hot tub. To fix this problem as much as possible, make sure that the one you go with is not made with materials that lose heat as well. If you do this, you should get about 20-30 minutes of good heat in the tub.


In-ground or custom styles are usually referred to as spas. They can be attached or adjacent to an in-ground swimming pool and are often placed near each other as a warm water and cold plunge-type of therapeutic experience. Others are stand-alone hot tubs, but set into the ground or custom built. Some are sturdy portable models (not inflatable) from top manufacturers that are installed to look like they are custom-built in-ground models that can be positioned upon a raised platform, sometimes under a pergola or a gazebo. Others actually are custom built and constructed of the same materials that pools are made of, like concrete, fiberglass, or gunite, along with stainless steel, tile, or copper.
There are numerous advantages and just as many disadvantages that one has to consider while looking to purchase an inflatable hot tub. Their specific situation, how and when they intend to use the hot tub as well as their specific taste will help them come to a decision. Below are some tips to consider before you make your final decision to buy or not.
You might be tempted to think that inflatable tubs are fragile, being easily prone to destruction. But this is not the case, high-end models having a quality construction that ensures they will last for a long time, and that they won’t be punctured easily and get deflated. Best of all, the quality materials used in the fabrication process provide comfort as well. After all, durability is not everything, being very important for them to offer a pleasant, relaxing experience when using them too. Most of the tubs on the market are made of polyester laminated PVC, a material that offers everything you need in terms of durability and comfort.

The Bestway SaluSpa Miami Tub is the best option for a good, not soak in the middle of winter.

There is a safety function built in to this pump system which automatically goes into hibernation if no button is pressed in 72 hours. If you have the heater system setup on timer and you don’t actually use the hot tub and press a button for 3 days it will turn off meaning a long re-heat if you don’t notice. This is less of a problem if you use your hot tub daily, but if you are a weekend user this can be a pain if you forget to go out and press a button to let it know you’re still there.
Follow the instructions for inflation of the hot tub as you should not trespass the recommended PSI measure. For hot seasons this is quite important because the air will expand with heat, specially when the tub is set under the sun. Most pumps that are included with the hot tub include a gauge so you can check those measures. When you inflate too much the tub, pressure will start to damage the connections of the tub with jet heads, tubes and other orifices, and this will lead to leaks, so don’t overboard.
Chlorine tablets smell bad in the bucket and bad in the spa. Bromine is a little bit better, but I can still smell it on my skin and on my hair hours after soaking. Have you ever opened up your spa cover and detected the strong smell of chlorine?  That’s the smell of combined molecules, either chloramines or bromamines. Salt systems are much less likely to produce these foul smelling mutations of chlorine, because after a chlorine molecule is used up, it reverts back to salt, a.k.a. sodium chloride!
I used my index lifespan for 4 months without any issues. The only time it stopped working was when I got an error message saying no water flow. I changed the filters out and never had a problem again. It did loose some air one night when the temp got to 37 days one night. I put some air in it the next day and it never lost air again. I love this spa! Its worth every penny. Now let’s see how the 2nd season goes. I’m setting it up May 1at. I will let you know how it does.

Our only concern was that we found no inflatable hot tubs with built-in seats. Now, there is a good reason for this, mainly because you don’t need them. It is very comfortable to sit in, but a little strange at first if you are used to having seats in your hot tubs or spa. The others reason being an inflating issue. If seats were part of the tub, they might be a weak spot and susceptible to stress tears. Also, less water is needed, which is more cost effective in maintenance costs.
Usually costing around $4,000 to $9,000 depending on type and size and location to be installed. But going the inflatable spa way will run you around $500, with no setup costs. And if you will only be using it part of the year, you simply deflate it and store it away. There are no costs of maintaining it to keep it from looking like something that the creature from the black lagoon would like to hide out in. Oh, and did we mention, to heat it up and keep it heated will run around $8-$12 a month depending on your electricity prices per kWh.
