There were errors in the original publication [1]. Typographical errors were made during the transfer of the results from the spreadsheet to the manuscript. Corrections have been made to Abstract and main text.

The corrected Abstract appears below:

Swimming pools, symbols of luxury in tourism-driven Greece, raise concerns about water consumption in water-scarce regions. This study assesses their hydrological impact in two regions of Southern Greece, West Mani (Peloponnese) and Naxos Island (Cyclades), within the water–energy–food nexus framework, evaluating the resulting trade-offs. Using satellite imagery, we identified 354 pools in West Mani (11,738 m²) and 556 in Naxos (26,825 m²). Two operational scenarios were evaluated: complete seasonal emptying and refilling (Scenario 1) and one-third annual water renewal (Scenario 2). Annual water use ranged from 39,000 to 51,000 m³ in West Mani and 98,000 to 124,000 m³ in Naxos—equivalent to the needs of 625–2769 and 1549–6790 people in West Mani and Naxos, respectively. In Naxos, this volume could alternatively irrigate 27–40 hectares of potatoes, producing food for 700–1500 people. Energy requirements, particularly where desalination is used, further increase the burden, with Naxos pools requiring 384–846 MWh annually. Although swimming pools are highly visible water consumers, their overall contribution to water scarcity is modest compared to household and agricultural uses. Their visibility, however, amplifies public concern. Rainwater harvesting, requiring collection areas 5–10 times larger than pool surface areas, especially in residential and hotel settings, could make pools largely self-sufficient. Integrating such measures into water management and tourism policy can help balance luxury amenities with resource conservation in water-scarce Mediterranean regions.

A correction has been made to Section 3.4, 3rd paragraph which is the following list with bullets:

• In Mani, a rainwater harvesting area should be 520% of the area of the pool if the pool is 1.5 m deep, and 870% of the area of the pool if the pool is 2 m deep.
• In Naxos, a rainwater harvesting area should be 690% of the area of the pool if the pool is 1.5 m deep, and 890% of the area of the pool if the pool is 2 m deep.

The typographical errors also affected Figure 7. The corrected Figure 7 appears below.
