Salt Water Hot Tubs
Over the past 15 years, salt water hot tubs have become increasingly popular; however, they are not without their setbacks. Below are some things to consider if you’re interested in salt water for your hot tub.
- Salt water hot tubs require a special cell that converts the salt (NaCl) into a gentler form of chlorine (Cl). Producing chlorine this way leaves you feeling refreshed after getting out of the tub and does not dry out your skin like regular chlorinated water can. It also does not create a chlorine smell that could potentially linger on your skin afterwards.
- Water conservation is a big deal to consumers as it can help them save money. Reducing the amount of waste is important to eco-friendly individuals. Salt water tubs tend to evaporate slower which may mean less frequent filling.
- Easy to clean as debris floats to the top of the pool. With this being said, you should cover your hot tub when it is not in use.
- While chlorine is generated as needed, alkalinity, pH and calcium hardness can still fluctuate and need to be maintained. In salt water, calcium hardness tends to increase faster than in chlorine and can lead to scaly buildup in your tub and on the salt cell.
- Since saltwater hot tubs require specialty parts, it may be harder to find a knowledgeable technician should any problems arise.
- Salt cells need to be replaced every 3-5 years on average and can cost hundreds of dollars depending on the model.
For those exploring hot tubs salt water vs chlorine, salt water systems offer a unique advantage in comfort. The lower chlorine levels create a spa-like experience, making a salt hot tub vs chlorine a popular choice for those who prioritize a gentle, natural feel during their soak.

Hot tubs with chlorine are something that a majority of people have been in at one point or another. Chlorine is well-known for killing bacteria and has been trusted around the world to so do. The benefits of having a chlorine hot tub and some drawbacks are as follows:
- Finding a dealer who offers salt cell equipped hot tubs can be difficult, whereas any hot tub can accommodate chlorine.
- Chlorine is highly effective at quickly getting rid of bacteria, though it can be easy to over treat your water.
- A hot tub maintenance professional should be able to help you balance your chemical levels, especially if they come for weekly maintenance.
- Using chlorine has a low start up cost as you do not need to have any specialty equipment.
- Chlorine levels should be tested weekly to ensure proper balance.
- Chlorinated water tends to evaporate quicker than salt water, but so long as you leave the tub covered when not in use, this should not be a problem.

Which Hot Tub Is Right for You?
Deciding between a salt water spa vs chlorine depends on your lifestyle, budget, and preferences. Are salt water hot tubs better than chlorine for everyone? Not necessarily—it comes down to what matters most to you. Salt water hot tubs are ideal for those with sensitive skin, as the gentler chlorine levels reduce irritation and provide a softer water feel. They’re also great for users who prefer low-maintenance systems, requiring less frequent testing and chemical adjustments. However, the higher upfront cost and potential for corrosion may deter some buyers.
On the other hand, a chlorine hot tub is perfect for those prioritizing affordability and ease of finding maintenance support. If you’re comfortable with weekly water testing and don’t mind the occasional chlorine smell, a chlorine system offers a reliable, cost-effective option. It’s also better suited for those concerned about long-term durability, as salt can corrode hot tub components over time. For those weighing salt water versus chlorine hot tub options, consider your tolerance for maintenance and sensitivity to chemicals to make the best choice.
