Keep the Pool Open All Winter on Mallorca, or Close It? The Honest Answer

On the mainland the question answers itself, but Mallorca winters are mild enough that keeping the pool open all year is a genuine option, and increasingly the default among owners who live here. Here is the honest comparison for 2026, including the water angle that has changed the maths.
The case for staying open
A pool kept running through winter needs only reduced filtration hours and occasional chemistry, and it never faces the two expensive moments of pool ownership: the spring recovery of a neglected pool and the 48,000 litre refill. Under water restrictions that refill is the step most worth designing out of your year, and winter swimmers with a heat pump get bonus months on top.
What winter running actually involves
Shorter pump hours, a cover against leaves and evaporation, chemistry checks that drop to a relaxed rhythm and an eye on the rare cold snap. Many owners move to a reduced winter service contract, the 150 to 250 EUR summer rate typically scales down with visit frequency, and the pool that greets you in March is the one you left in November.
Who should still close
Rarely used second homes with no service contract and no one nearby are the honest case for a proper winterisation, an unwatched pool is better put to sleep correctly than left half attended. If that is you, our winterising guide covers the right way to do it, closing badly is the most expensive option of all.
The decision in one line
If someone, you or a service company, will see the pool most weeks, keep it open and covered. If nobody will, close it properly. The worst outcome every spring is the pool that was neither maintained nor closed.
