For many, a hot tub is the ultimate backyard upgrade. It offers a space to relax, unwind, and connect with family and friends. But as you consider adding one to your home, there’s a decision to make: when it comes to saltwater vs traditional hot tubs, which is the better choice for your lifestyle?
Both options can deliver the relaxing, therapeutic experience you’re looking for. However, depending on your lifestyle and preferences, one type of hot tub might be a better fit for your backyard.
Whether you’re considering a saltwater hot tub or just curious about how it compares to traditional options, understanding the pros and cons can help you make a confident, informed choice.
What is a saltwater hot tub?
A saltwater hot tub is exactly what it sounds like — a spa with salt added to the water. Using advanced technology, the system converts the salt into chlorine through a process called electrolysis. This ensures a consistent level of chlorine, which keeps the water clean and safe to use. Although it still relies on chlorine, a saltwater system can offer a gentler, more seamless experience compared to manually adding chlorine.
Benefits of saltwater hot tubs
A backyard hot tub isn’t just a place to unwind; it’s a way to support your overall well-being. When your goal is to live life better, you want every soak to feel as healthy and rejuvenating as possible.
That’s why many homeowners are choosing saltwater spas to create their own backyard oasis. These systems offer unique advantages that can elevate the experience, from water that’s gentler on your skin to simplified maintenance that makes relaxation even easier.
Gentler on skin and eyes
For many, their first experience with salt water is at the beach — splashing in the waves, feeling the water lap over your feet, or riding a bodyboard. It’s all fun and games until a wave splashes into your eyes, and you’re met with that unmistakable sting. So, it might come as a surprise that saltwater hot tubs are actually gentler on your skin and eyes.
Saltwater spas have much lower salinity than the ocean, and they also use less chlorine than traditional systems. Smart systems like Master Clear automatically generate just the right amount of chlorine, avoiding over-chlorination. This keeps the water balanced and comfortable, making it far less likely to cause skin irritation or eye redness.
Lower chemical maintenance
Owning a hot tub means keeping an eye on the water’s chemical balance, often a few times a week or before each use. While it doesn’t take much time — usually less than 15 minutes a week — a saltwater system can make water care even easier. The salt cell generates a consistent amount of chlorine, so you’ll spend less time measuring and adding sanitizers. For busy families or first-time hot tub owners, this simplified maintenance can be a major perk.
Softer, more natural water feel
The water in a saltwater hot tub often feels silkier and more luxurious. Many owners report that soaking in a saltwater spa leaves their skin feeling smooth and refreshed rather than dry or tight.
Fewer odors
Traditional chlorine systems can sometimes have a chemical smell, especially if the water isn’t properly balanced. When the water is in good shape, though, the odor isn’t usually an issue. Saltwater hot tubs, on the other hand, tend to have a much milder scent, making the soaking experience feel fresher and more enjoyable. This is because the saltwater system produces chlorine in small, controlled amounts, keeping the water balanced and reducing any strong odors.
Eco-friendly option
If you’re looking to make a more eco-friendly choice for your backyard, a saltwater hot tub might be the perfect option. Because saltwater systems produce chlorine as needed, they typically require fewer packaged chemicals, reducing both waste and the environmental impact of maintaining your spa. Not only will you enjoy a cleaner, fresher soaking experience, but you’ll also feel good knowing you’re making a more sustainable choice for your home and the planet.
Cons of saltwater hot tubs
While saltwater hot tubs have plenty of advantages, it’s important to weigh the potential drawbacks.
Higher upfront cost
Saltwater systems typically have a higher initial price tag compared to traditional chlorine hot tubs. The salt chlorine generator is an additional piece of equipment, and the system’s advanced technology can add to the cost. However, some owners find that the long-term savings on chemicals help offset the initial investment.
Generator maintenance and replacement
The salt chlorine generator is an essential part of a saltwater hot tub, but it’s not entirely maintenance-free. Over time, the cell might accumulate calcium buildup. That means it could require cleaning, and eventually, replacement. These maintenance costs are an important factor to consider when choosing your system.
The Master Clear Salt System simplifies this process with the Smart Cell, which needs to be replaced annually. Replacing it is quick and easy. You simply disconnect the wire, remove the Smart Cell from the filter housing, and swap it out. A built-in magnet keeps it securely in place, making the process hassle-free.
Potential for corrosion
Salt is naturally corrosive, and over time, it can affect some components of your hot tub, like metal parts or heaters. While Master Spas are built to handle this exposure, regular care and maintenance are important to help prevent damage.
The Master Clear Salt System is designed with this in mind. It operates at a lower salinity level of 1,200 parts per million (ppm), which helps reduce the risk of corrosion. Plus, it only generates chlorine when necessary, further minimizing wear and tear on your spa’s components.
Learning curve
Switching from a traditional chlorine spa to a saltwater system can take a little getting used to. You’ll need to learn how the generator works, keep an eye on salt levels, and manage the water balance, which might feel like a bit of a learning curve.
With the Master Clear Salt System, though, much of that curve is smoothed out. The system automatically monitors sanitizer levels and only activates when needed. Planning to have friends over on a Saturday night? No need to worry about adjusting the settings. Plus, with the Master Clear app, you can easily check sanitizer levels and monitor the life of the smart cell. Master Spas also offers a helpful library of videos, making it easier than ever to keep your hot tub in top shape.
Saltwater vs traditional hot tubs: A comparison
When comparing saltwater vs traditional hot tubs, both offer a clean, relaxing soak, but the best choice depends on your personal preferences and priorities. Here’s a quick comparison to help you decide:
Ease of maintenance: Saltwater systems generally require less hands-on chemical balancing, while traditional systems might need more frequent adjustments.
Water feel: Saltwater is softer and less likely to irritate the skin and eyes, while traditional chlorine can sometimes feel harsher.
Upfront cost: Traditional hot tubs are usually less expensive initially, but saltwater systems can offer long-term savings.
Environmental impact: Saltwater systems can reduce chemical waste, making them a more eco-friendly option.
Tips for buying a saltwater hot tub
If you’re deciding between a saltwater vs traditional hot tub, here are some key factors to keep in mind to ensure you make the best choice:
Understand the upfront costs: Saltwater systems typically have a higher initial price. Make sure your budget accounts for the salt chlorine generator and any other necessary components.
Do your research: Not all hot tubs can be converted to saltwater systems, so it’s important to check with the manufacturer or dealer to make sure the model you’re interested in is compatible. With the Master Clear Salt System, however, there’s a convenient conversion kit that can be added to virtually any hot tub, making it easy to enjoy the benefits of saltwater technology.
Think about long-term maintenance: Although saltwater hot tubs need fewer chemical adjustments, you’ll still need to clean and replace the generator cell periodically. It’s important to factor these maintenance costs into your decision. With the Master Clear Salt System, however, the cell only needs to be replaced once a year, and it’s designed for easy, hassle-free changes. This makes ongoing upkeep simpler and more manageable.
Choose the right size and features: Look for a hot tub that fits your space and meets your needs, whether that’s ample seating, hydrotherapy jets, or energy-efficient features.
Talk to an expert: A reputable retailer, such as your local Master Spas dealer, can help you navigate the options and explain the benefits of saltwater systems. Don’t hesitate to ask questions and seek advice.
Evaluate warranty and support: Ensure that your investment is protected with a good warranty and access to reliable customer service.
