A villa with a saltwater pool in Croatia – at first it sounds like overkill, since the sea is salty enough. Yet it's one of the questions we're asked most often before a booking: what does it feel like? Does it sting your eyes? Is it suitable for children? All three of our villas in Kaštel Stari, between Split and Trogir, have a heated saltwater pool. Here we explain what that means day to day – without spa promises nobody can keep.
What a saltwater pool is – and what it isn't
A saltwater pool isn't a bottled piece of the Adriatic. There's far less salt dissolved in the water than in the sea, and you can barely taste it. An important point, because it's often misunderstood: a saltwater pool is disinfected too. With saltwater systems, this usually happens by generating the disinfectant from the dissolved salt directly in the circulation, rather than adding it by hand. So "chlorine-free" would be the wrong term – which is why we don't use it.
Many people find saltwater softer, with less of the typical "indoor swimming pool" smell. That's a subjective experience, not a medical claim. If you have very sensitive skin or eyes, do what you'd do after any swim: rinse off briefly, wear goggles for long swims, and if you have known skin conditions, ask your own doctor beforehand.
Saltwater pool vs sea vs conventional pool
| Adriatic off Kaštela | Our saltwater pool | |
|---|---|---|
| Salt content | high, you noticeably float | much lower |
| Temperature April / October | approx. 15–16 °C / approx. 20 °C (according to our guide) | heated from end of March to October |
| Getting in | pebbles and rock, water shoes recommended | no pebbles, no sea urchins |
| Wind & waves | maestral in the afternoon, sometimes murky after the jugo | no waves, clear pool water |
It's not either-or: most guests head to the sea in the morning or evening – the beach and promenade are around 1 km, or 10–15 minutes on foot, away – and spend the hot midday hours by their own pool. Which beaches are worth it is covered in our guide Beaches & Nature between Split and Trogir.
Saltwater and children
For families, a private pool means one thing above all: you can keep an eye on everything. No other people's children, no battles over sunbeds, no walk to the hotel pool. What saltwater doesn't change: children in and around the pool must always be supervised – whatever the water treatment. A few practical points:
- Rinse off briefly after swimming – that makes sense for both sea and pool.
- Take a midday break in the shade. Between 12 and 4pm there's little to be gained in summer, as our family guide stresses.
- Baby equipment such as a cot, high chair and baby monitor we provide free of charge. More under Holiday with a Baby in Croatia.
- At Villa Just be Alive the garden is fenced, and there's a trampoline and table tennis – for days when the pool takes a back seat.
Heated: when the pool is warm
- End of March to October: large saltwater pool heated, at no extra charge. That turns April, May, September and October into proper swimming season.
- Hot tub: heated all year round and controllable independently of the pool – and, we think, rightly described as "extra hot".
- November to March: only the hot tub is heated; the large pool rests. On request we heat it for a surcharge equal to the electricity costs.
Why this is the real difference in the shoulder season is explained in our guide Heated Pool in the Shoulder Season.

Frequently asked questions
Is the saltwater pool chlorine-free?
No, and we don't want to gloss over that. Saltwater pools are disinfected too – just differently from a pool where chlorine is added by hand. Many people find the water more pleasant; there's no guarantee for sensitive skin.
Does the water sting your eyes?
The salt content is much lower than in the sea. How much you notice it varies from person to person – for long underwater sessions, we recommend goggles, as anywhere.
Is the pool heated in winter?
From November to March only the hot tub is heated. We heat the large pool on request for the cost of the electricity – we don't promise a pool heated all year round.
Can I swim lengths in the pool?
A few relaxed lengths, yes – best at Just be Light with its 10-metre length. It isn't a sports pool.
