As you found your way to this page, I have a suspicion that you already know what an inflatable hot tub is. However, let me spend a moment and talk a little about the subject, give you my thoughts on this fantastic available fun pool.
Wikipedia defines a hot tub as:
A hot tub is a large tub or small pool full of water used for hydrotherapy, relaxation or pleasure.
It goes on to say that some have jets for massage purpose.
This is a great definition of a hot tub, which can also be called a spa and Jacuzzi. Now you could point out the fact that some baths have just the same. They can have jets, colour lights and other features.
However, the one defining difference between a bath and a hot tub is that a hot tub can be enjoyed by more than one person at a time.
So, we know a hot tub is a large tub or small pool full of water. An inflatable hot tub is simply a cheaper inflatable version of a hot tub.
Therein is the big difference. A fixed solid hot tub can cost you thousands of pounds to buy whereas an inflatable hot tub will cost you a small percentage, generally in the hundreds of pounds.
You can still enjoy the same relaxation in an inflatable hot tub, the same as in a fixed hard hot tub.
An inflatable hot tub; also referred to as a portable hot tub or spa; can also be packed away and even taken away. A regular fixed hot tub, once fitted, will stay. Even if you move house. Whereas an inflatable hot tub can go with you.
When it comes down to it, there is little difference between an inflatable hot tub and a fixed hot tub in regards to relaxation. There are some differences in how they work, but the end user experience is the same.
Which you would prefer to buy is down to buyers choice. If you have the spare money and are not going to be moving, then a fixed hard hot tub may be the way you would prefer to go.
An inflatable hot tub gives you more flexibility and will cost you just a fraction. However, the choice is yours.
