Different Types of Hot Tubs and Why They’re not all Jacuzzi

No, Jacuzzi is not the Japanese mafia. It is a term we most regularly use to describe a hot tub where we spend quality time for fun, pleasure or therapy.

It’s a pretty common ‘’umbrella’’ term used to describe a tub with a mechanism that uses hot water for massage and relaxation. The question is though, is this single term enough to explain different types of the item, do we all think the same thing when we talk about this?

The answer to this question lies in the text below where we will try to present as many different types of hot tubs as you find interesting to read about.

What is a Jacuzzi?

First of all, let’s explain what Jacuzzi is. It is actually a renowned brand of hot tubs that people started using to cover all the different types of this item under one term.

Hotels may have helped establish this name for general use because of the way they advertised it. After all, a room with Jacuzzi sounds more attractive than a room with a hot tub.

So consequently people just adopted it to describe all kinds of hot tubs, even if it was produced by a completely different manufacturer.

The Jacuzzi family, as well as licensed dealerships like Aqua Paradise, has been trying to prevent their name from becoming “community property”, but alas not with much success.

Hot Tub

In the United States, the term hot tub is used to describe a pool with various tools used for hydrotherapy or just for casual fun and relaxation. It’s usually filled with hot water, which is pretty self-explanatory.

Hot tub does not particularly describe one single item which is concretely separated from other items who serve a similar purpose, but a line can be drawn as there still are some parts which differentiate one from another.

For example, a classic hot tub is usually made of wood, it is round and there are simple seats on the side. There are around 5-10 water jets, depending on the size, and the overall design and function are pretty basic. It’s a nice pool-looking tub, convenient for the house, and just right for a nice soak.


The general use for the term spa is basically a water therapy practiced in natural springs and resorts. Their primary selling point is mineral water with its therapeutic power to help treat various conditions. These places are popular all-over the world.

In the US we introduced this word to describe a hot tub, or to be more precise, an improved version. The jets used in these spas are much stronger and generate a more substantial effect during a massage.

You can also adjust the type of pumping, shape, size, and strength. They can be added to a previously built pool, placed above ground as a regular hot tub, or even inground.

Jetted Tub

The jetted tub is another pretty self-explanatory term. So what is it and what makes it different from a hot tub or a spa?

It’s pretty simple. It is a regular tub enhanced with jets which provide pretty much the same effect as those in a spa or a hot tub. These jets are connected to a circulation pump via pipes.

Some models may even include a heater, and you can also choose a size which works best for you, but the price will also go higher with more adjustments and gadgets.

This all sounds familiar and you wonder why this is called a jetted tub. Why a different name for a very similar purpose?

Well, the main difference between a jetted tub and a hot tub or a spa is that the water is always drained after use, just like a regular tub. You also don’t need water filters or cover.

Whirlpool Bath

What is a whirlpool bath? We’ll keep this one short and simple, it’s the same thing as a jetted tub and it is actually a trademark name registered by the Jacuzzi family. All the functions are pretty much the same.

Therapy Tubs

Last but not least we have therapy tubs, these are primarily used for physical therapy and for sports injuries.

You can fill them with either hot or cold water, depending on the treatment you want and they can come with an electric heater or a circulation pump.

They are made of stainless steel and can usually be found in facilities designed for recreation. They can be used to treat tired muscles or to help prevent inflammation by soaking injuries in an ice-cold water.
