What better way to relax after a hard day of work, commuting, and stress than to get in a hot tub of your own and have a relaxing bath?

The thing is, when we think of spas and different thermal water pools, the first thing that pops into many people’s minds would be those Japanese mountain lakes with those little capuchin monkeys running about.

Or, perhaps, some Nordic country with its many hot water sources and lava lakes.

Now, if you happen to live in these places, getting yourself a spa treatment is a piece of cake, but what if you don’t have access to these wonders of nature but would still very much be interested in such a treatment.

Well, in this article, we’re going to talk about hot tubs, and how one of these can make your relaxation and bathing dreams come true – in the comfort of your home. As you will see, these curious contraptions represent the state-of-the-art bathing installations and they can truly do wonders to help you unwind after a hard day’s work with their many options and different modes of function you can choose from. We will explain how these things work, so you can have a clearer idea of what sort of functionality you’re getting if you decide to buy one of these.

Right then folks, without further ado, here’s the deal.


What is a Hot Tub?

As you may have already guessed, a hot tub is an elaborate type of bathing tun representing a sort of spa you can use without going outdoors. (Unless you’ve installed yours somewhere outdoors, that is.)

The idea behind it is that its elaborate construction combined with many different parts onboard can mimic the functionality of real hot spring. This is achieved by using a variety of water heaters, bubble makers, and fans operating within the tub itself.

Also, many manufacturers add further items such as advanced lighting, so that you can use these during the night or in other poorly-lit environments.

How Does a Hot Tub Work?

Since hot tubs feature a number of different uses, the important thing to take into consideration would be to understand that in order to make one work, you have to connect it to the electrical grid in your house. (Or, wherever it is you intend to put it.)

The thing is, connecting a hot tub to your electrical grid system is often more complex than simply plugging in a couple of cables here and there, so it is advised you get the help of an electrician for this part of the setup. Of course, if you’re an electrician yourself, you may be able to pull this off on your own, but if not – it’s better to spend some money to set this thing the proper way than to run the risk of messing it up completely.

Parts of a Hot Tub


The hot tub cabinet represents a supportive structure typically made out of wood or some other sturdy material that acts as a de facto fence for the hot tub itself.

You can think of it as housing for the hot tub and the many items you can find underneath it. The purpose of a hot tub cabinet is to protect those parts as well as the shell of the hot tub, while also looking good from the outside. Without it, you’d be able to see all the itsy-bitsy ‘innards’ of a hot tub, which can make the bathing experience a little bit less pleasant.

Typically, there is a way to open the cabinet, so you can access the various parts and systems of the hot tub itself more easily if it needs fixing, for example.


The shell of a hot tub is the part of it that you lay in or sit in when you want to have a bath inside.

It’s typically made out of some sort of acrylic or a special breed of thermoplastic because it needs to be tough and durable enough to withstand the weight of multiple people as well as all the water you pour into it.

Hot tub shells are typically also reinforced by fiberglass and various forms of foam so that their structural strength, as well as their thermal insulation, can take on the bathing sessions you’re about to have in these.


Representing probably the most popular part of any hot tub, water jets (or simply – jets) are those tiny contraptions that spew water at a certain pressure under the surface.

This creates the sensation of massage and relaxes the person inside of the tub. The way this work is that the pumps that make these mix the surrounding air with the water inside to create small bubbles that are then propelled inwards, where they reach the person in the tub and produce their great effect.

In many hot tub models, the intensity of the jets can be set to different values, so you can set it to whatever speed you fancy.


When it comes to actually control how your hot tub runs and what intensity of bubbles you want the jets to produce, for example, you do it all by setting the controller to the right value.

Modern-day hot tubs usually come with controllers with touchscreen displays, where all of the different parameters are shown you can set up. So, this is the place where you will set the temperature of the water, the intensity of the jets, the lighting arrangement, as well as the music player. (That’s only if your hot tub comes with a music player, of course.)

Hot tub controllers are typically located somewhere where you can reach them if you’re in the tub itself, as well as if you’re outside of it. Also, they are usually made to be water-resistant, so you can rest assured that you won’t break them if you’re setting something up from the tub itself.

The bottom line, hot tubs represent a simple and easy way you can get yourself a part of a mountain spa or an Icelandic hot water geyser – in the comfort of your own house. These machines do tend to be a tad pricey, but it more than pays off to get one if you aren’t interested in having to pay too much for spa visits or for traveling abroad every time you want a relaxing bath.
