Small hot tubs that accommodate two adults and are designed for a more intimate experience measure about 3 to 4 feet high by 5 feet across and hold approximately 500 gallons of water. Larger hot tubs measure around 4 to 5 feet high and 6 feet or more in diameter and are built to accommodate up to 8 adults or more. They hold about 850 gallons of water.
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.
Another drawback to certain models of inflatable hot tubs is the location of the filter or filters. While many models place the filter right inside the heater/pump unit for quick access, some models place the filters along the bottom inner portion of the spa, so changing them becomes a much more involved process than just opening the pump unit and popping in a new filter.
Once inflated, this portable spa has a dimension of 77 x 28 inches. It has enough height to easily get in or get out of the tub. The side walls are 20 inches thick, allowing one to sit comfortably on the side as well. On the same note, the sides are very sturdy because of a PVC-like material installed inside the walls. This ensures that the unit remains sturdy and firm.
The Canadian Spa Company is one of the most renowned and respected brands on the market. In 2015, this global brand has even won the Best of Class Award, this title being deserved due to the high-end hot tubs that they have delivered to customers. For over 30 years, they have managed to bring joy to those looking for great-performing hot tubs at fair prices. As time has passed, this brand has focused on innovation and quality, this being the main reason why they have managed to provide impressive tubs like the top of the line CSCHTRG29 Rio Grande.
The main issue against saltwater hot tubs is that salt causes corrosion. At levels of 2,000-3,000 ppm, there should be no worry about damage to finishes and pool equipment. There is one material in particular that doesn’t like salt, that being Buna rubber, which some pump shaft seals are made of. Again, at normal levels, there should be no concern. But if your pump seal begins to leak, we do have pump shaft seal made for high salt or ozone conditions.
Of the 3 main inflatable hot tub brands, this hot tub is the largest and has the most bubble jets (140). With an 85-inch diameter and 290 gallon capacity, this Intex model provides more personal relaxation space than any other. More room means it is easier to stretch out and easier to sink down so that bubbling water is lapping around your shoulders. That said we think 4 people is the comfortable max.

Inflatable hot tubs consume a lot of water, up to 250 gallons (almost 1000 L) so people will not be happy changing it every week as the water bill will become quite salty. On the other hand, the same water can’t be used forever, so soon or later you will have to replace it, but it all will depend on how often the inflatable hot tub is used and how well you treat the water.
When you get your tub to the correct temperature you will need to use some chemicals for water maintenance, there is a chemical floater included. You can buy chemical kits from amazon.com or go to your local pool shop for advice. Note: there is a 72 hour automatic hibernation process on the pump which you need to override by resetting the temperature otherwise it will just shut down.When you’re ready to try your tub it’s only a press of a button to start the bubble massage and you can have 30 minutes non stop relaxation.
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.

. Although it's a company that has been around since the 1950s, when it started making pumps that could be submerged in bathtubs, people often use the word to describe a spa or hot tub, even if it's another brand. All describe a large tub that is used for relaxation, hydrotherapy, warmth, and entertaining. All are equipped with built-in jets for targeting bathers' sore muscles. 
If you are looking for a modern, spectacular tub, then you have to expect to pay some extra cash. The SaluSpa Paris does fit this pattern, coming at a higher price than other hot tubs, but providing you with great features that make up for the investment. Undoubtedly, its biggest highlight is the LED light show which helps set a relaxing, fun mood.
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?
This product fit's the Coleman Lazy Spa very well. The cover does not fit over it very well so I suggest removing it before attaching the cover, otherwise it will just get knocked loose when you remove the cover, and you will have to put it back on. We set a small light on it and two 12oz adult beverages, and had no problems with it being unstable. I will probably purchase one more.
Since we started reviewing inflatable hot tubs in 2015, we have spent more than 40 hours finding some of the best tubs on the market and then did in-depth research to discover stand-out features. We have contacted manufacturers with numerous questions to clarify issues and discover unique features. We also consulted with professionals and industry insiders to increase our expertise and get informed opinions about the best tubs out there. 
A built-in hot tub is really heavy – and it is built-in. You cannot carry it around. It is more or less a permanent fixture in your home. If you want to move it, you will have to spend several days just disassembling it. You will have to hire an electrician and plumber to help you with the more technical aspects involved in installing or disassembling a traditional hot tub.
One of the people’s main concerns when it comes to owning an inflatable spa is the fact that they do not think that they are ‘up to the job’. Trust me when I say that blow up hot tubs nowadays are better than they have ever been. The quality of the materials used means that you can place them on just about any flat surface and not have to worry about them ‘breaking’.
Electrical rate: Is very unlike to see inflatable tubs with 220V systems, because they will not heat water over 104ºF, and the filtering and blowing systems don’t require a lot of potency. The 110V compatibility is unanimous so, while that doesn’t mean you cannot implement it on your 220V household system, you will need a transformer to make it work.
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.
That's what these inflatable hot tubs offer you. They come to you deflated, almost mysterious in their packaging. You unwrap and inflate them anywhere you have electricity. Fill them with pure water and turn them on. The electrical current warms up a heating element kept in a separate filtration compartment through which the water gradually circulates.
This is best for the people who aren’t really all that impressed with the massage jets. That’s not all that strange because many Intex portable spa reviews consider the hot water in itself as the main therapeutic and relaxing feature of the tub. If you don’t care about the massage features, then that’s fine. After all, you can always think of that feature as another thing that can go wrong in the Intex inflatable hot tub.

Accessories There is a large variety of accessories that help maintain them in a great shape or help enhance the experience for those who use them. These accessories are the carry bag, the cover, the filter cartridge, and the chemical floater. The cover ensures insulation when it is not in use for the heating process to go faster when it will be put to use once again. It also ensures increased safety for those who have children, making it impossible for the small ones to use it without adult supervision. The carry bag provides a convenient transportation method when deflated. The other accessories that we have mentioned, more precisely the filter cartridge and the chemical floater ensure that the water will remain clean and safe to sit in.

The price is a marvel, and it’s very democratic. What it really means is that the inflatable hot tub experience is really no long exclusive for the well-off. How long will it take you to save $400 for a tub? Probably not all that long, right. And it doesn’t add much to your electricity bill, with some people saying it will add about $80 to you monthly electricity expenses. That’s for keeping it ready every day!
The Design – The design of this product is something else that is worth mentioning – it has one of the coolest spa designs currently on the market. With a dimension of 70 x 66 x 29 inches, there is more than enough seating. Due to the deeper seating, the spa is more comfortable. The spa also comes with a high-quality cover and the air mixing valves make for a soothing massage.
