In this detailed review, you will learn the benefits that you’ll experience with this inflatable spa, as well as its caveats.

SaluSpa Siena AirJet Review

Siena Airjet Product Image

SaluSpa Siena is part of the AirJet series of inflatable hot tubs manufactured by Bestway. This brand is also known for manufacturing other inflatables such as airbeds and sofa.

The main characteristic that sets this product apart from other models is that out of all the 2 person inflatable hot spa that we recommend, this is the only one with a max capacity of 2. You can certainly use a 4-person inflatable hot tub with just two people, but they’re not as compact as this model.

It also comes with a beverage tray which allows you to have your favorite drinks while soaking. The hot tub is made of sturdy Tritech materials so you don’t have to worry about the tray or your drinks flipping over.

Like other inflatable hot tub models, Siena is very easy to set up and easy to maintain. It costs way less than an actual regular Jacuzzi or hard-shell hot tubs. It has a built-in massage system, heating system, and filtration.

Saluspa Siena is a new addition to our list of our comprehensive inflatable spa reviews for this year. Read further as we expand on its features and limitations, so you’ll have a clearer picture of why we have shortlisted this model.

Massage System

Bubble Jet Massage SystemImagine how it would feel like to get a massage while soaking in your bathtub. It not only feels great but it’s so relaxing to both your mind and body.

This is what the bubble massage system installed with every SaluSpa Siena can do. There are 120 bubble jets that line up the bottom perimeter of the tub. Activating the bubble jets will make it pump warm air through the water, giving your body a light massage.

The bubble jets run independently from the heating system, which is a great feature if you just want to soak in warm water.

If you’re residing in a place where the outside temperature is quite cold, you’ll need to refrain from using the bubble massage continuously. The bubble jets blow in ambient air so expect the water temperature to drop faster than usual. The best way to remedy this is to set this inflatable spa indoors.

Heating System

Insulated cover traps heatDid you know that soaking in hot water not only feels soothing but also helps improve blood circulation?

SaluSpa Siena can heat up the water for up to 104 degrees Fahrenheit (40 degrees Celsius). In common with other inflatable hot tubs on the market, it cannot go beyond this temperature.

The water is heated up at the rate of 2 to 3 degrees Fahrenheit per hour. Depending on the outside temperature and the initial temperature of the water, it may take up to 18 hours for the water to reach 104 degrees.

The control unit allows you to adjust the temperature to your preference. You can also set a timer when the heater should turn on or off. This feature allows you to set up the water beforehand so you can soak as soon as want to when you get home from work.

Filling it up with a hot or warm water should give you a great start and will significantly lessen the heating time. It also comes with an insulated cover to further help with heating up the water.

Filtration System

Keeping the water clean is made easy by Siena Airjet’s built-in filtration system.

This system turns itself on when the heater is turned on. It will automatically shut itself off after 72 hours unless you manually override it.

It already comes with a free filter cartridge so you can use it right away. There’s also a chemical floater which allows you to place chlorine or bromine tablets.

If you’re concerned about the noise of the filter/pump, we can assure you that it’s not disturbingly loud. In fact, you can turn on the heater and enjoy a quiet soak. It’s only when you turn the bubble massage that you get to experience some noise similar to a small vacuum cleaner.


Best for couplesOut of all the portable spa models that we have reviewed on this site, this is the only one which is specifically designed for two people. The unique shape emulates that of a bathtub.

This allows you to stretch your legs fully and enjoy the experience with your entire body. If you’re using this alone and you’re 6 feet tall, you can definitely lay stretched out and float in the water.

It’s about 2 1/2 to 3 feet deep which is more than enough depth to even submerge you in water.

It has built-in handles to the sides so you can easily get in or get out of the spa. The seats are inflatable and give ample cushion while sitting in the hot tub for a longer amount of time.

However, if you’re planning to use it with more than one person, It’s unique feature becomes its biggest limitation. If you know you’re going to have more than 2 persons using this, in the long run, it is best to get the 4-person or 6-person variety.

Setting Up

SaluSpa Siena is very easy to setup, which requires no tools and professional help. As a matter of fact, it can be done in about 10 minutes barring the tasks of filling and heating up the water.

The image below, which comes straight from the manual, should give you a quick overview of how to set this portable hot tub up.
Setup visual instructions

When this portable spa is filled up, it weighs around 1,200 to 1,300 lbs. You’ll need to take this into consideration if you’re planning to place this on a deck or a raised platform.

If you’re planning to use it during winter, you need to make sure that the outside temperature is not below 40 degrees Fahrenheit. This is because the materials cannot withstand temperatures colder than 40 degrees.

Even if you decide to force start it, the system will not turn itself on as a precautionary measure. Additionally, UL certification only allows inflatable hot tubs to operate within the range of 40 degrees to 104 degrees Fahrenheit.

There is a quick workaround to this, though.

If you have your portable spa setup outside, you’ll have to move it indoors where you have better control of the temperature. You can place it in a basement or garage for example. You just need to make sure that there are dehumidifiers in place and a proper provision for draining the water.


If you’re going to use the spa regularly, you’ll have to perform maintenance more often. Fortunately, it’s not that tedious at all.

Cleaning the filter just involves removing it and hosing it down. The manufacturer recommends that you replace the cartridges weekly. However, we do believe that it will all depend on your usage.

The best time to replace the filter cartridge is when it remains soiled and discolored even after cleaning it. The cartridges can be easily ordered online and come in packs of 12 or 6.

To keep the water and the inflatable hot tub clean, you’ll also need to make sure that you use the chlorine tablets with the chemical floater. This will help to maintain the alkalinity of the water.

If you need to drain the water, you can easily do so by unscrewing the drain plug on the inside of the spa. You can then attach a hose to lead the water out.


Compact dimensionsSaluSpa Siena has an inflated dimension of 25.98 x 98.23 x 58.66 inches and weighs 78.9 lbs. This does not include the control unit/pump that you will have to attach to the side. If you take this into consideration, you will need an area of at least 99 x 70 inches to place this blow-up spa.

The inner dimension is around 78 x 41 inches, which is big enough even for a 6 footer. The electrical cord is 10 feet long and has a GCFI plug to help prevent accidental electrical shocks.
