Freshwater Vs Saltwater Pool: Which to Choose?

Last Updated on November 3, 2021 by Kravelv

A swimming pool is an inviting feature where you can enjoy a relaxing evening, host a barbeque, and have a dip in water to beat the heat.

Above all, it can turn your outdoor area into a luxury oasis.

Planning to build a pool in your backyard?

freshwater vs saltwater pool

Well, you can choose between freshwater and saltwater pool. Both are popular options and require the pool maintenance devices like a filter, pump, electric pool cover, pool enclosure, and heater.

However, there still exists a huge line of differences.

Read the blog to understand the meaning, pros, cons, and the difference between the two options.

Freshwater pool

Freshwater swimming pools are the best alternative to traditional chlorine or saltwater pools.

In a freshwater pool, you have to manually add chlorine tablets in your pool. The frequency depends on the size and usage of the pool.


  • Inexpensive repairs
  • Lower initial cost
  • Requires less electricity
  • Does not cause damage to your pool


  • Requires a lot of chlorine
  • May cause you skin problems
  • Needs to be shocked more often
  • Frequent maintenance
  • Requires additional chemicals
  • High maintenance cost
  • Strong odor

Saltwater pool

Saltwater swimming pools are commonly found in cruise ships and beachside resorts.

However, in recent times they have become immensely popular among luxurious homes.

These pools also use chlorine but in the form of gas.


  • Softer Water
  • No skin irritation
  • Fewer impurities and minerals
  • Cheaper maintenance


  • Costly installation
  • Salt may corrode and damage metal parts
  • Uses more electricity
  • Repairs may require professional help


Some points of difference between the saltwater and freshwater pool are:

1. Chlorination process: Chlorine is added to both pools but in different forms.  In a saltwater pool, the chlorine gas is released by a chlorine generator into the water. In a freshwater pool, it is added manually in the form of tablets or chemicals. 

2. Energy consumption: Since saltwater pools require running a chlorine generator for longer periods, this leads to higher energy usage. The same is not true for the freshwater pools as chlorine is added manually.

3. Sanitation performance: With a saltwater pool, you have a constant flow of chlorine being released by the generator. This saves you from the hassle of buying, handling, or storing chemicals.

In a freshwater pool, chlorine is added periodically and once it disappears, you have to add it again.

4. Water quality: You will find a difference in the quality and taste of both the pools. In saltwater pools, the water feels gentle and softer on the skin, providing a more enjoyable swimming experience for long hours.

However, in freshwater pools, water is harsh and is not suitable for long swims

5. Odor: If you hate the pungent and strong smell of chlorine, avoid a freshwater pool. Moreover, excessive chlorine can irritate your eyes and skin.

However, saltwater pools have no smell and are less harsh on your skin, eyes, and swimwear.

6. Corrosion: Saltwater pools can cause corrosion and can damage the metal parts and pool equipment that may require professional help.

However, the same is not the case with freshwater pools.

7. Maintenance cost: Freshwater pools require adequate chemicals and chlorine products. The higher the usage of chemicals, the more the maintenance cost.

However, you’ll probably spend less on maintenance if you opt for a saltwater pool.

Which is best for you?

If you want to save on a maintenance cost, a saltwater pool is probably a good solution.

And if you want to save on electricity costs, go for the freshwater lake.

However, the choice still depends on your needs and budget.
