As anyone who’s ever owned a Saltwater Hot Tub or worked at a swimming pool knows, one of the biggest problems with large bodies of stagnant water is the filtration. The water in seas, rivers and lakes purify itself naturally by coming in contact with the surrounding soil. Swimming pool and a hot tub water on the other hand, can gradually become dirtier to the point of unsafety. Even if no insects or dead leaves enter your hot tub, filling it with tap water means you need to purify it first. Here’s when saltwater hot tubs come into play.

One of the ways filtration can be achieved without using harmful chemicals is through a process called electrolysis. Pouring salt into water that is turned into chlorine through a saltwater chlorinator. A special machine that makes the process possible.

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

Without further ado, here’s the deal.

What is a Saltwater Hot Tub?

To put it simply, a saltwater hot tub is exactly the same contraption as a regular hot tub. The only difference is that the one with salt uses the salt to filter the water. Since filtration using salt is safer and more natural than chemical filtration, many people see saltwater hot tubs as superior to the regular ones. This is reflected in the price of these contraptions.

The Pros of Saltwater Hot Tubs

Less Skin and Eye Irritation

When it comes to the chemicals used during the filtration, many people find that chlorine (or bromine) used for this purpose 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. These models are preferred by the people who find the ordinary hot tubs too much to handle.

Excellent Buoyancy of Saltwater Hot Tubs

It’s way easier to float in a saltwater hot tub than it is in a regular freshwater. The reason for this is that salt increases the viscosity of water, which then makes it more difficult for your body to sink. For example, the Dead Sea is so salty that you naturally float on the surface. It’s practically impossible to drown in it because you physically can’t sink. The same principle applies to saltwater hot tubs, though to a considerably smaller effect.

Floating can have positive effects on your joints and muscles – 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. People who are particularly sensitive to pressure and movements (due to an injury or arthritis, for example) can experience soem real benefits.

Easy Maintenance of Saltwater Hot Tubs

You can rest assured when it comes to the amount of maintenance you have to perform on saltwater hot tubs. Cleaning will be much easier than the amount of work you would need to clean up a conventional hot tub. 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. This in turn means you won’t have to pour chemicals into it regularly. Pair this up with the low cost of salt for that chlorine-making contraptions.

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. Thanks to the lower maintenance of the salt-based models, you can eventually get the return on investment though.

Corrosive Properties of Salt

When it comes to salt and its interaction with metal, it’s a fact that the two don’t go together well. Mercifully, however, the salt in saltwater hot tubs won’t hurt the body of your hot tub. The tub shells are typically made out of carbon fiber, plastic, acrylic, or some other similar non-corrosive material.

If your hot tub does come with some parts that are made out of metal, you should clean these thoroughly after every use. Otherwise, you run the risk of the salt damaging them.

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