As anyone who’s ever owned a hot tub or worked at a swimming pool knows, one of the biggest problems with large bodies of stagnant water is the filtration.

The thing is, the water in seas, rivers, and even lakes purify itself naturally by coming in contact with the surrounding soil, while water in a swimming pool and a hot tub can gradually become dirtier and dirtier to the point where it’s no longer safe to bathe in

Heck, even if no insects or dead leaves enter your hot tub, the fact alone that you’re filling it with tap water means that you need to purify it first because we all know how unsafe tap water is for drinking.

Now, one of the ways filtration can be achieved without using any potentially harmful chemicals is through a process called electrolysis. The way this happens is that you pour some salt into the water and then that salt is turned to chlorine by a saltwater chlorinator – a special machine that makes this process possible.

In this article, we’re going to talk about saltwater hot tubs and why these contraptions are becoming increasingly popular nowadays. We will also talk about some of the downsides to these contraptions, so you can get a clearer idea of whether or not it would be smart for you to get yourself one of these.

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

What is a Salt Water Hot Tub?

To put it simply, a saltwater hot tub is exactly the same contraption as a regular hot tub, the only difference being that the one with salt uses the salt to filter the water.

Since filtration using salt is safer and more natural than regular filtration using various chemicals, many people see saltwater hot tubs as superior to the regular ones, which is a view also reflected in the price of these contraptions.

The Pros of Salt Water Hot Tubs

Less Skin and Eye Irritation

When it comes to the chemicals used in hot tub filtration, many people find that chlorine (or bromine, in some cases) that are used for this purpose in regular (non-salt) hot tubs irritates their skin and eyes upon contact.

Hot tub versions with the salt-based filtration, on the other hand, don’t irritate the skin as much, if at all, so these models are usually preferred for the people who find the ordinary hot tubs too much to handle.

Excellent Buoyancy

If one thing is sure about salty water, it’s that it’s way easier to float on it than it is on regular freshwater. The reason for this, of course, is that salt increases the viscosity of the water, which then makes it more difficult for you to sink through it.

For example, the Dead Sea (which is a lake really), is so salty that you can float on it without even trying. What’s more, it’s practically impossible to drown in it because you can’t even sink.

The same principle applies to saltwater bathtubs, though to a considerably smaller effect, of course. The salt in the water will make it easier for you to float, which can have positive effects on your joints and muscles – because you won’t be applying pressure to them while bathing.

Granted, bathing in any sort of hot tub won’t put up too much pressure on your joints, but for people who are particularly sensitive to pressure and movements (due to an injury or arthritis, for example) can see some real benefits from using a saltwater hot tub instead of a conventional one.

Easy Maintenance

When it comes to the amount of maintenance you have to perform on saltwater hot tubs, you can rest assured that cleaning up these will be much easier than the amount of work you would need to clean up a conventional hot tub – mostly because salt itself does most of the job when it comes to filtration, which is where most of your time goes cleaning up a regular model.

The fact that saltwater hot tubs use salt to clean the water inside the shell means you’ll be able to reuse the water more times, and that you won’t have to pour chemicals into it all the time. Pair this up with the low cost of salt for that chlorine-making contraptions and you can rest assured that your saltwater hot tub won’t take too much money out of your pocket, or too much time out of your…, ehrm … watch.

The Cons of Salt Water Hot Tubs

High Initial Cost

Truth to be told, all hot tub systems tend to be fairly expensive, but saltwater hot tubs tend to be even more expensive than the ordinary tubs. Of course, thanks to the lower maintenance of the salt-based models, you can eventually return the difference you put in initially, so the difference in costs between these two will clear themselves out sooner or later.

Corrosive Properties of Salt

When it comes to salt and its interaction with metal, it’s a well-known fact that these two don’t go together that well.

Mercifully, however, the salt in saltwater hot tubs won’t hurt your hot tub body, because the tub shells are typically made out of carbon fiber, plastic, acrylic, or some other similar non-corrosive material.

That said, if your saltwater hot tub does come with some parts that are made out of metal, you should take good care to clean these thoroughly after every use, because otherwise, you run the risk of the salt catching up with them, so to speak.

All in all, getting your own saltwater hot tub is a sound investment that is going to pay off better the longer this curious tub is in your possession. Whether you suffer from some sort of injury and you want a hot tub that can help you with the therapy, or you fancy buying a hot tub model where you won’t have to do much maintenance, a saltwater hot tub model can be just what you’ve been looking for.
