Saltwater pool or classic pool (complete comparison)
Updated: 3 days ago
Do you know what the biggest reason why 80% of people switch to a saltwater pool is?
It's not that it's "modern." It's not that it "saves money."
The biggest reason is simple – they are tired of:
❌ red eyes after swimming
❌ dry, itchy skin
❌ that chlorine smell that sticks to your hair
❌ constant addition of chemicals every day
Today we will answer the question that bothers many pool owners - saltwater pool or classic pool ?
But – not everything is so black and white.
A saltwater pool also has its DISADVANTAGES . And if you don't know about them, they can cost you hundreds of euros.
That's why I made this guide.
In the next 5 minutes, we'll go over EVERYTHING - pros, cons, costs, maintenance, and answers to frequently asked questions.
In the end, you will know EXACTLY which pool is for you.
What exactly is a saltwater pool? (busting the biggest myth)
People think, "A saltwater pool? Well, it's like the sea – just salt and nothing more."
INACCURATELY.
A saltwater pool DOES have chlorine. The only difference is HOW the chlorine is produced .
How does a classic pool work?
You manually add chlorine to the water:
Tablets in skimmer or float
Granules that you dissolve in water
The liquid chlorine you pour in
The chlorine is ready – just throw it in. When you use it up, you add new one.
It's like turning on the heating manually - turn it on, it heats up, cools down, turn it on again.
How does a saltwater pool work?
The system has an electrolytic cell that:
It takes salt from water (sodium chloride)
It passes an electric current through it.
It breaks down into chlorine , which disinfects the water.
It's like having a thermostat – the system adds chlorine when needed.
Important: The saltwater pool is NOT chlorine-free!
This is the most common misconception.
A saltwater pool produces chlorine – the same chlorine that disinfects water.
The difference is that chlorine does not have byproducts (chloramines) that smell and irritate.
That's why there's no smell. That's why there's no red eyes. That's why the water is more pleasant.
Comparison at first glance
Classic pool | Salt pool |
You add chlorine manually. | The SAM system produces chlorine |
Chlorine levels are jumping up and down | Chlorine level is STABLE |
You have chlorine "shocks" | No sudden oscillations |
The smell of chlorine is strong. | No smell |
Irritates eyes and skin. | It is gentler on the skin. |
H2 –What is CHEAPER? (costs over 5 years)
This will surprise you.
Most people think: "A classic pool is cheaper – I just buy chlorine tablets and that's it."
At first – yes.
But let's calculate it for 5 years .
Annual cost – classic pool
Item | Price |
Chlorine tablets (12 months) | €150–200 |
Shocking granules | €50–100 |
Algaecide (against algae) | €30–50 |
pH of chemicals | €30–50 |
Flocculant (water clarification) | €20–40 |
ANNUAL TOTAL | €280–440 |
× 5 years = €1,400 – €2,200
Annual cost – saltwater pool
Item | Price |
Salt (2–3 bags per year) | €10–30 |
pH of chemicals | €30–50 |
Algaecide (occasionally) | €20–30 |
Electrolytic cell (every 5 years) | €200–700 = €40–140 per year |
Cell cleaning (agent) | €10–20 per year |
ANNUAL TOTAL | €110–270 |
× 5 years = €550 – €1,350
5 YEAR DIFFERENCE
Classic | Salty | DIFFERENCE | |
5 years | €1,400–2,200 | €550–1,350 | SAVINGS €850 |
But wait – there's also an INITIAL INVESTMENT
Charge | Classic | Salty |
System (chlorinator) | None | €500–€2,500 |
First salt | None | €20–40 |
So:
Classic | Salty | |
1st year | €280–440 | €630–€2,780 |
5 years | €1,400–2,200 | €1,180–3,580 |
When is a saltwater pool worth it?
O If your chlorinator costs:
€500 → pays off in 2 years
€1,000 → pays off in 4 years
€1,500 → pays off in 6 years
CONCLUSION: If you use your pool for a LONG time (5+ years) – a saltwater pool is worth it. If you use it for 2–3 years – a classic pool is cheaper.
What is EASIER to maintain?
Classic pool – daily, weekly, monthly
DAILY:
Check the chlorine level
Add tablets if needed
PER WEEK:
Test pH, chlorine, alkalinity
Add chemicals as needed
Shock the pool (shock chlorine)
MONTHLY:
In-depth water testing
Filter cleaning
Saltwater pool – daily, weekly, yearly
Salt pool
DAILY:
Check that the system is working (2 minutes)
PER WEEK:
Test the pH
Check the salt level
Check the chlorine level
PER YEAR:
Clean the cells from electrolysis (15 minutes)
Maintenance comparison:
Task | Classic | Salty |
Adding chlorine | EVERY DAY | AUTOMATIC |
Testing | 2–3 times a week | 1 time a week |
Shocking | Monthly | Rarely |
Chemicals in the home | BUNCH OF BOXES | Salt + pH |
Weekly weather | 30–60 minutes | 10–15 minutes |
Winner? SALT POOL – no debate.
What is MORE COMFORTABLE for you and your children?
Classic pool:
Classic chlorine pool
✅ Excellent disinfectant
❌ Higher likelihood of eye irritation
❌ Dry, tight skin
❌ The smell of chlorine that sticks to the hair
❌ Higher concentration of CHLORAMINE (these are the compounds that stink)
Salt pool:
✅ Excellent disinfectant
✅ The water is SOFTER and more pleasant
✅ No red eyes
✅ Less skin irritation
✅ No odor
✅ Hair remains soft
✅ Swimsuits last longer
What does science say?
A study of 1,001 users in 20 indoor pools showed that chlorine pools were MORE likely to cause eye and skin irritation, respiratory problems, and dry skin than salt electrolysis pools.
If you have CHILDREN, sensitive skin, or ALLERGIES – a saltwater pool is a CLEAR WINNER.
3 Disadvantages of a Salt Pool That NO ONE Tells You
A saltwater pool isn't perfect. Here are 3 things you need to know.
Flaw #1: Corrosion
Salt can CORROSION metal parts:
Ladder
Handrails
Even a pump if it is not made of the right material
Decision:
Use STAINLESS STEEL parts.
Add a PROTECTIVE ANODE
Rinse metal parts regularly with fresh water.
Disadvantage #2: Cell replacement
An electrolytic cell doesn't last forever.
How long does it last? 3–7 years
How much does a replacement cost? €200–700
Decision:
Think of it as a "service charge"
It is still BETTER than chlorine in the long run
Wash the cell regularly – it lasts longer
Flaw #3: Repairs
A chlorinator is a COMPLICATED device.
If it breaks:
You can't fix it yourself.
You need an EXPERT
The repair costs
Decision:
Buy QUALITY electrolysis (not the cheapest)
Final conclusion – WHICH ONE TO CHOOSE?
Choose a SALT pool if...
✅ You have €500–2,500 for an initial investment
✅ Use the pool for a LONG time (5+ years)
✅ YOU HAVE CHILDREN or SENSITIVE SKIN
✅ You want LESS work
✅ You don't want the smell of chlorine
✅ You want stable chlorine levels
Choose a CLASSIC pool if...
✅ You have a SMALLER BUDGET (initially)
✅ Use the pool OCCASIONALLY
✅ You like to have FULL CONTROL
✅ You don't mind the smell of chlorine
✅ You have experience with chemistry
Recommendation:
If you have a budget and plan to use your pool long-term – choose a SALT pool. The water is more pleasant, less work, and it pays off in the long run.
If you're just starting out, have a smaller pool, or use it infrequently – a classic one is fine. Just expect more work and chemicals.
Frequently asked questions:
Is the water in a saltwater pool as salty as the sea?
NO. A saltwater pool has 3,000–5,000 ppm of salt. The sea has 35,000 ppm . That's 7–10 times LESS.
You will feel a slight taste, but it is not like swimming in the sea.
Can I shock a saltwater pool?
YES. Completely normal.
If you need to act quickly (after heavy rain, lots of swimmers, pollution) – add chlorine as you would to any other pool.
How often should I add salt?
1–2 times a year.
Salt is not wasted – it is only lost through filter rinsing, splashing, and occasional water loss.
You add 2–3 bags a year and that's it.
How long does an electrolytic cell last?
3–7 years , depending on:
Cell qualities
Frequency of use
Regular cleaning
Do I need a special technician for a saltwater pool?
NOT. You keep it classic:
Monitor pH
Clean the filter.
Test the water occasionally
The only additional thing – clean the cell 1–2 times a year (takes 15 minutes).
What if the electrolysis breaks down?
Call a repairman or replace the cell.
Tip: Buy QUALITY electrolysis - not the cheapest. You will pay more initially, but less in repairs.
