Why Can’t I Use Regular Salt in My Saltwater Spa?




Oohhhh…There’s nothing like slipping into the soothing luxury of a saltwater spa. Your stress melts away, your muscles relax, and aches and pains fade into the distance like the quiet of the sunset. There’s no place you love better than your backyard retreat. And you’ve been using your spa solitude to do some thinking. Now a question has come to mind. Wouldn’t it be great if you could cut corners on salt for your spa? You’ve already got some up in the cabinet. It’s salt, for goodness sake. What’s the worst that could happen?

Hold up a second.

Before you make a HUGE mistake, we’ll ask you one big favor. Trust us. You need the RIGHT salt for your hot tub. Don’t settle for anything less.

Why Can’t Table Salt Go in My Spa?

Useful and inexpensive, salt is an excellent resource for use in all sorts of instances. From sprinkling on your food to sprinkling on your sidewalk in icy weather, salt is one thing we all have on hand. Not only does it add flavor to life, but it’s also fantastic for all sorts of other uses. Wouldn’t it be easy to use that same salt in your saltwater spa?

Salt is just salt, right? Well, not exactly. There are many different versions of salt. But the salt that you are thinking of can cause you some issues if you throw it in your hot tub. First, table salt isn’t pure salt. It has binders and other additives that may be present. Don’t go dumping this into your hot tub. These additives can interact poorly with your spa chemicals since table salt is not tested as a salt solution for hot tubs.

Table salt also is very small. The mini-sizes granules dissolve too quickly in hot water. You want special salt that sanitizes your spa. Salt that contains sodium chloride is going to interact with your cell to convert to usable natural chlorine. You won’t get that transaction with any old table salt.

What Should I Use? Are There Any Other Options?

When owning a saltwater spa, you need quality chemicals. Spa salt is the perfect size granule, it is pure, and it won’t interact incorrectly with other spa chemicals. But are there other options? Absolutely! And we’re so glad you asked.
