Ideal Size for Your Needs Is it for just solo or 2-person dips? Or are you planning on having the whole family enjoy the tub? Its size should suit your plans on how you’re going to use it. What you may realize is that a supposed 6 person portable hot tub is actually a comfy 4 person portable spa. A 4 person hot tub is really a 2 person portable spa, with perhaps 2 small kids. And you don’t want to get a 2 person portable hot tub unless you plan on using it solo.

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.
Attach the control unit to the inflated Coleman hot tub using the marked connectors, they should match up no problem and it’s easy to hand tighten them both together. Screw in the filters, make sure the drain plug on the bottom is closed and then you’re ready to fill up with water. There is a mark on the inside of the tub so you know the correct level of water to fill it to. This is a simple outline of what needs doing. There is a dvd included to show you exactly what to do. You can have your tub filled in next to no time.
The amount of time it takes to heat up will all depend on the product you buy, however, they all have electric heaters (not gas). So, the amount of time it takes the portable spa to heat up in comparison to the amount of time it takes the traditional spas to heat up will be longer. After about one hour, the water temperature will increase by 2 or 3 degrees. If you plan on setting the tub up and using it for a long period of time, then this isn’t going to be a downfall. However, if you just want to use it during the weekends, you need to schedule the set-up one day in advance so that the water will be fully heated.
When you think of a blow-up hot tub, what do you picture? Don’t picture a soft, flimsy pool toy – it’s nothing like that. If you get the opportunity to use one, you’re going to be surprised at how sturdy it is. These spas do have that “softer” feel to them and personally, we find this much better than sitting on hard plastic or concrete …it’s more relaxing.

This Coleman inflatable hot tub as 120 bubble jets installed at the bottom. They are designed to suck in air from the outside and blow through the water. This means turning on the bubble jets can lower the water’s temperature. We advise to heat up the water several degrees higher than your preference before taking a dip to address this shortcoming.
The pump and the hot tub are easy to connect together but you need it to be simple to use while you are in the tub. All the controls are press button, and they are set in a circular style display with a led display in the centre. From the top left there is an auto-lock button which activates in 5 minutes, to release press for 3 seconds. Next is the timer button so you can decide when you want the heater to come on and you can also set the temperature. You have a filter button to turn the filter on and off, a light shows when it is on, you have the option to display the heat in Celsius or Fahrenheit and then there is a heater button to start the heating function, the temperature can be adjusted with the arrow buttons but most people heat it to the maximum 104F. Finally you have the bubble massage button which when pressed automatically turns off the heater. All of these buttons can be accessed from when you are seated in the tub.

This is probably the most conspicuous advantage of inflatable hot tubs. A lot of inflatable hot tub reviews mention these when the features match what you see in built-in models. Have a customized built-in hot tub installed and you’re likely to spend up to $20,000 for the initial costs. But an above-ground version can be available for less than half the cost, with some ranging from a high as $8,000 to as low as $3,000.And if $3,000 is still too much, don’t worry. That’s because the inflatable version is the most affordable of them all. We actually found some portable hot tubs with prices in the mere hundreds of dollars!
This tub is made of six-layer laminated PVC material called Rhino-Tech. It has vertical interior vinyl panels to give it support and prevent sagging over time. It comes with a carrying case and only weighs 66 pounds, making it quite portable before you inflate it. The Alpine M-009LS’s combined pump and heater unit is built into the tub wall, unlike most inflatable hot tubs that have external heating systems. The digital control panel extends out from the side of the pool so it’s within easy reach. The heater raises the temperature up to 104 degrees Fahrenheit, but it raises the temperature 2 to 3 degrees per hour, so you’ll have to start heating the day before use. As with other tubs, the integrated air blower doubles as an inflator and the power behind the 120 bubble jets. It comes with a pressure gauge to avoid over-inflation. It also comes with a protective ground mat that is just a little larger than the tub’s footprint, but it’s not cushioned as mats on other tubs are. This inflatable spa comes with two filter cartridges which attach to the inside of the tub. It also comes with a garden hose adapter for the drainage spout, making it easier to empty the tub. The Alpine M-009LS has a fitted top cover with a foil lining to retain heat. The cover is secured with locking straps, but instead of being integrated into the tub, as some tubs are designed, it latched to the ground mat.
An inflatable hot tub is made of several layers of thick, strong and solid vinyl rubber. The rubber becomes inflexible when completely inflated; thus, providing genuine and reliable protection. The materials used in the manufacture of inflatable hot tubs are tough, sturdy and long-lasting. You can expect it to withstand rowdy water play, jabs, appalling weather, and the accumulation of debris.

This kind of filtering is not very common as it is expensive but works really fine for beach scenarios where the salinity of the water can go beyond the normal. You don’t have to worry either about leaving the sea and getting into the tub right after. The tub filtering will cope with it just fine, while regular machines wouldn’t.Hawaii is not the largest of the tubs in the Lay-Z-Spa series, but it is wide enough to make a spacious hot inflatable tub: a 71-inch diameter and 28-inch tall. The tub is enough to fill 210 gallons of water (795 L), which are heated up to 104ºF (40ºC) within 30 to 45 minutes. You can also set the temperature and the functioning time of the tub through the digital control panel that is implemented over the heating and filtering tank.To set Hawaii things also go smoothly: it will be fully inflated in less than 5 minutes, though you have to follow the instructions accurately to connect the pump and all other hoses appropriately.

Maximum Heat Capability It shows what is the maximum temperature that the water can reach. When choosing the products, we made sure that they all feature a maximum heat capacity of around 104°F. This is the ideal temperature for the water to reach, being high enough for the experience of soaking in it to be as pleasant as possible without there being any repercussions.

It has 2 water treatment systems installed. The hard water treatment system keeps the water soft, which helps prevent the skin and hair from drying up. It also makes sure the unit remains in tip-top shape by preventing any chemical build ups which may damage it. We believe that this is an important feature, considering that this is a premium inflatable spa.
It has enough room to sit 4 people according to the manufacturer. As with all other “4 person hot tubs”, get ready for some intimate time with your buddies. This is fine if you are close friends, but not so comfortable if you are not. The exterior layer is a brownish synthetic leather. It is a matter of personal preference, but we don’t like it at all.
A quality inflatable hot tub can last for years. They are made of sturdy material and can withstand temperatures of up to 100 degrees Fahrenheit and more. The sturdy material comes in handy when heavy people are using the hot tub. So if you are large, you don’t have to worry that the hot tub will deflate from your weight. They are sturdy and can take a lot of wear and tear. They are firm and will hold you no matter what position you are in when using them. You can lean back or stand up, and the hot tub will stay strong. You can also get a tub that can support the weight of as many as four people, so you get to share your hot tub fun with friends and family.
Rapid Heating System It is crucial because it shows that the tub will be ready for use fast. In the fast-paced world we live in, speed is a very important element to look for, so we gave higher ratings to models that were able to heat up the water more rapidly.

Salt systems, for pools or spas, have trouble producing chlorine at low water temperatures. When water temperatures drop into the 60s, very little chlorine output is generated, even though your salt cell is working overtime. Many salt systems will shut down, in a self-protection mode, when low water temps are sensed. This of course, is not a big deal for spas and hot tubs, so long as you keep the water 65° F or higher. Do this, and you’ll have no problems.

If you Have Enough Space Before you buy a portable inflatable hot tub, make sure your planned location for it will suit your needs. Do you have just enough space for the best small hot tub? Does the area have a socket where you can plug in the cord? Is there a drain system in place? Does it have sharp rocks that may puncture the tub? Is it even level?

It is true that inflatable hot tubs are less durable compared to a built-in hot tub. But it’s very difficult to effort built in hot tub as they are very very costly. Many inflatable hot tub reviews highlighted this product is cost efficient, Affordable, Easy to portable and durable. Inflatable spa tubs last more if you follow the maintenance guide and precautions while using  it.
Inflating your tub is easy, but you need to ensure that you do not end up over inflating it. Do not go overboard when doing it for the first time. Keep in mind that the factors like the direct sunlight and heat will increase the pressure. Therefore, you should not inflate it to the maximum – you can always add more air when you know it can handle more.
The cost of running an inflatable hot tub depends on a few major factors: electricity, water, filters, cleaning and chemicals. To a lesser degree, other factors will contribute to hot tub maintenance costs, like its size, where you set it up, how often you use it and how strict you are about cleaning it. Electricity costs vary by state, so running a hot tub may be less expensive in Louisiana residents than in Alaska or Hawaii.

Intex doesn’t really offer the massage jet and the saltwater system for this model. This one’s main selling point is its size, as supposedly it can fit 6 people. As noted in several Intex inflatable hot tub reviews, that means it can fit 4 adults comfortably. However, you may want to back up the heater with a tankless water heater especially when you use it outdoors.

Even though this SaluSpa Hawaii HydroJet is inflatable it’s made from some strong stuff. The walls are super durable by the layering of a reinforced material like a sandwich between 2 layers of pvc. This protects it from sharp objects and minimises the chance of punctures. As well as the thickness of the pvc it uses I-beam construction in the sides of the hot tub so it has enough stability for you to sit on the edge without it bevelling. This still keeps the comfort factor for when you lean against it while relaxing in the tub.
Just like regular hot tubs, inflatable models require some maintenance work to be done for them to be safe to use. The good news is that it does not take long to perform any of the maintenance tasks typical for inflatable hot tubs, and these tasks do not require you to put a lot of effort into them either. There is a total of 4 chores that you cannot skip on, chores that we will explain here.
Hot tubs also offer several different designs and styles of seats. Some hot tubs have ergonomic seats that can fit the height and build of each person. It is useful in targeting specific areas of the body that needs to be massaged. Today, it can be made in both indoors and outdoors, both fixed and portable due to new high-quality laminate materials.
Ikaria also just happens to be home to one of the first, and certainly one of the most famous hot tub collections in history, as the island was known for its hydrotherapy. Was it the residual heat from Icarus' burnt wings that kept the waters warm? Probably not, but the healing properties of hot water have been used this way around the world for millennia.

Different inflatable tub model will have a different mode of installation so make sure to read the manual prior to assembling the unit. Also make sure to watch installation DVD if included or watch YouTube videos of other customers who have successfully installed their own inflatable hot tubs. If still uncertain and have more questions, you can always call your inflatable hot tub’s customer service hotline.


This Coleman hot tub has a bright green outer layer with a white inner lining. It’s 77 inches in diameter and can seat 4-6 people although it is probably more comfortable with only 4. It can be set up in the garden or in the garage or basement wherever you want to place it as long as it’s a flat surface. All you need is the ability to plug it into an electrical outlet and be able to fill it with water and have a drain within reach when you have to empty it.
