Understanding Saltwater Hot Tubs

How Saltwater Sanitation Works

Ever wondered if you could enjoy a hot tub without all the chemicals? Saltwater systems might just be your answer.

Here’s how it works. Instead of chucking in chlorine every few days, you add a small amount of salt to the water. A clever bit of tech—called a salt chlorinator—then turns that salt into sanitiser using electrolysis.

The result? Clean, clear water that’s kind on your skin and doesn’t reek of chemicals. It’s science, but make it spa-worthy.

Benefits of Saltwater Systems

Saltwater hot tubs are becoming a firm favourite across the UK. From family homes to holiday lets, they’re popping up everywhere—and for good reason.

You don’t need to top up chemicals constantly. The water lasts longer between changes. And the feel? Silky-smooth. No more dry skin or that weird chemical smell clinging to your hair.

They’re also easier on the wallet over time, thanks to fewer ongoing treatments and a more stable water balance. Win-win.

Advantages of Saltwater Hot Tubs

Gentler on Skin and Eyes

Remember the last time you left a hot tub with red eyes and itchy skin? Yeah, not ideal.

Saltwater tubs skip the sting. They’re noticeably gentler, even if you’ve got sensitive skin or little ones jumping in and out.

Think spa day at home—without the side effects.

Reduced Chemical Odours

Let’s be honest, no one loves smelling like a public pool after a soak. Saltwater tubs are refreshingly neutral.

You won’t catch a whiff of chlorine when you walk past, and your skin won’t carry that chemical scent for hours.

Just clean water, pure and simple.

Easier Maintenance

Keeping a traditional hot tub in check can feel like a part-time job. Test this, balance that—it’s a lot.

Saltwater tubs, on the other hand, are a bit more chilled. They regulate their own chlorine levels, which means fewer tests and fewer surprises.

A quick strip test once a week? That’s usually all it takes.

Hot Tub Brands and Models with Saltwater Systems

Not every hot tub can handle salt. So if you’re thinking of going down the saltwater route, stick to brands that either offer salt systems built in or make it easy to upgrade.

Example Brand 1: H2O Hot Tubs Saltwater Models

H2O Hot Tubs have built quite the reputation in the UK—and for good reason.

They offer several models that are saltwater-ready or can be upgraded with a kit. Most of their spas run on Balboa control systems, which are ideal for salt compatibility.

The insulation’s smart, the pumps are energy-efficient, and the setup is plug-and-play—especially handy for first-timers or those renting out a property.

Plus, their UK-based support team is just a call away if you ever need help.

Example Brand 2: Platinum Spas Saltwater Models

Looking for something sleek that doesn’t drain your bank account? Platinum Spas could be your perfect match.

Many of their models are compatible with saltwater systems—and a few even come with salt-friendly parts already fitted. They're stylish, reliable, and ideal for everything from garden parties to post-work wind-downs.

You’ll find plenty of choice in terms of size and features, so there’s something for every space and budget.

Other names worth checking include Superior Spas, Canadian Spa Co., and AquaSolus Spas—just double-check salt compatibility before buying.

Maintaining a Saltwater Hot Tub

Saltwater hot tubs make life easier, no doubt about it. But like anything, they still need a little TLC.

Balancing Salt Levels

Think of your salt levels like the seasoning in a good stew—too much or too little and things go wrong fast.

Aim for a level between 2,000 and 3,000 ppm. Your manual (or your supplier) will confirm the sweet spot.

A weekly check with a salt test strip will help you stay in that happy range. It only takes a minute.

Cleaning the Salt Cell

The salt cell is the heart of the system, and like anything hardworking, it needs the occasional clean.

Over time, minerals build up and reduce its efficiency. Every few months—say, every 3 to 6—just remove the cell and give it a gentle rinse using the recommended solution.

It’s a simple job, but it keeps the whole system ticking over beautifully.

Water Testing

Even with salt doing most of the heavy lifting, don’t ditch your test kit just yet.

You’ll still want to check:

• pH levels (between 7.2 and 7.8 is ideal)

• Alkalinity (target 80–120 ppm)

• Chlorine output (make sure it’s generating enough sanitiser)

Most of this can be done with a simple test strip. It takes no time at all and saves you from cloudy water or unexpected surprises.

Conclusion: Soak Smarter, Not Harder

Saltwater hot tubs aren’t just another fancy feature—they’re a smart investment.

They’re gentler, cleaner, and far easier to maintain than the traditional chlorine-filled alternatives. Whether it’s a relaxing home spa or a fuss-free rental setup, going salty just makes sense.

Brands like H2O Hot Tubs and Platinum Spas make it easy to upgrade your soak without overcomplicating your life. And once you’ve tried a saltwater tub?

You’ll wonder why you ever did it any other way.
