Buying Guide for Best Saltwater Hot Tub

Looking to purchase a saltwater hot tub but not sure where to start? Our definitive buying guide includes everything you need to know about the benefits of saltwater systems, popular brands, and key features to look for. Upgrade your home spa experience with confidence using our expert advice.

Salt System

A salt system is an essential feature to look for when purchasing a saltwater hot tub. This system generates chlorine using salt dissolved in the water, eliminating the need for traditional chlorine chemicals. This makes the hot tub easier to maintain, as there is no need for frequent chemical adjustments. Additionally, the saltwater is less harsh on the skin and can be more enjoyable to soak in. Overall, a salt system provides a more convenient and enjoyable hot tub experience.


Looking for the appropriate size when purchasing a saltwater hot tub is significant as it determines how many people can fit inside it comfortably, how much water it can hold, and how much space it will take up. A sizeable hot tub will provide enough room for people to stretch out and relax while a smaller hot tub will be more suitable for couples or individuals. Additionally, larger hot tubs require more maintenance and take up more space, while smaller hot tubs are easier to manage and fit into smaller areas. Therefore, determining the appropriate size for a saltwater hot tub is essential to ensure that it meets your needs and space requirements.


Jets are an essential component of a saltwater hot tub. They help to circulate the water, which is crucial for effective filtration and chemical distribution. In addition, jets provide the hydrotherapy feature that makes hot tubs so popular. The pressure and motion of the water are perfect for soothing sore muscles and reducing stress. Furthermore, jets of saltwater hot tubs never get too hot or too cold, because the saltwater maintains a consistent temperature.

Multiple jets are also beneficial. With more jets, you get a greater surface area for massaging your body. They also help to create a more even massage experience throughout the hot tub. Some hot tubs have directional and adjustable jets, so you can customize the massage experience based on your preferences. Additionally, they can produce different types of massages such as pulsating or rotating, which can help you relax even more. All things considered, be sure to choose a saltwater hot tub that has an ample amount of high-quality jets to achieve the best experience possible.

Water Capacity

Water capacity is a crucial factor to consider when purchasing a saltwater hot tub. The ideal capacity should be based on the number of people expected to use the hot tub. This aspect is highly critical because it determines how much water is required to enable the number of people expected to use the hot tub to comfortably settle in the tub.

The water capacity of the hot tub also affects the quality of the water. A tub that lacks enough water capacity will quickly get contaminated by bacteria and algae since the level of chlorine in the tub will not be sufficient. With a well-sized water capacity, maintenance costs can go down significantly, and the water in the hot tub can remain fresh and clean for more extended periods. A correctly sized water capacity also enables the hot tub to function more efficiently, thus saving energy costs in the long run.


You should look for a heater when purchasing a saltwater hot tub because it is essential for maintaining a consistent and safe temperature. Without a proper heating system, the water in the hot tub can quickly become too cold or too hot, leading to discomfort and even potential health hazards. A high-quality heater is also designed to be energy-efficient, which can significantly reduce the operating costs of your hot tub while ensuring that you can enjoy it for hours on end without worrying about your electricity bill. Ultimately, opting for a hot tub with a reliable, efficient heater will ensure that you can relax and unwind in warm, welcoming water whenever you want.

Energy Efficiency

Energy efficiency is an important factor to consider when purchasing a saltwater hot tub. These types of hot tubs can require a lot of energy to keep the water at the desired temperature, especially if used frequently. By choosing an energy-efficient model, you can save money on your energy bills and help to reduce your environmental impact.

One way to ensure energy efficiency is to choose a hot tub with good insulation. This can help to trap heat inside the unit, reducing the amount of energy needed to maintain the temperature. Additionally, energy-saving features such as timers and programmable controls can allow you to set the hot tub to turn on and off at specific times, so that it is only in use when you really need it. By considering energy efficiency when purchasing a saltwater hot tub, you can enjoy all the benefits of a hot tub with less impact on your wallet and the environment.


Looking for a reasonable price when purchasing a saltwater hot tub is necessary to ensure that you do not overspend on a product that you could have bought for a lower cost. By comparing prices from different sellers, you can find the most affordable option that still meets your needs. Furthermore, choosing a cheaper option can free up additional funds for other important purchases or activities. However, it is important to ensure that the cheaper option still meets your desired level of quality and features. Ultimately, considering price is vital to making a wise purchase decision.


It is important to look for a reputable brand or manufacturer when purchasing a saltwater hot tub to ensure the quality and reliability of the product. A well-known brand typically indicates a level of expertise and experience in designing and producing high-quality saltwater hot tubs that meet industry standards. Additionally, established brands often have a customer service team available to provide support and guidance throughout the lifespan of the hot tub.


Is a salt water hot tub worth it?

Yes, a salt water hot tub could be worth it as it offers benefits such as gentler on skin and eyes, less chemical residue, and lower maintenance costs in the long run compared to a traditional chlorine hot tub. However, it may have a higher initial cost and may require additional equipment for proper maintenance. Ultimately, it depends on personal preference and priorities.

What hot tub brands use salt water?

Some hot tub brands that use salt water include Sundance Spas, Jacuzzi Hot Tubs, and HotSpring Spas.

What are the negatives of a saltwater hot tub?

The negatives of a saltwater hot tub include higher upfront costs, potential damage to the hot tub components, and the need for regular monitoring and adjustment of pH levels. Additionally, saltwater hot tubs may not be suitable for individuals with certain health conditions or sensitivities.

Do salt water hot tubs last?

Yes, salt water hot tubs can last as long as traditional hot tubs with proper maintenance and care. However, they may require more frequent inspections and replacements to prevent corrosion and maintain the effectiveness of the saltwater system.

Last Words

In conclusion, the HotSpring Grandee Spa has managed to secure the position of the best saltwater hot tub due to its exceptional features, including the advanced Saltwater system that eliminates the need for harmful chemicals. It’s ideal for those who prioritize health and safety above all else. The Caldera Tahitian Spa comes a close second with its impressive variety of features, making it worth considering as well. In summary, any of these two saltwater hot tubs would be a great choice for anyone considering investing in the best saltwater hot tubs available on the market.
