Terme Portorož, LifeClass Hotels & Spa

Terme Portorož sits inside the LifeClass Hotels & Spa resort on Obala, the main seafront strip in Portorož. It centers on two kinds of water: heated seawater pools and thermomineral-water pools, the latter a local specialty on this stretch of the Slovenian coast. Pool temperatures generally run 30–31°C, with hot tubs around 36°C, and the complex is open every day of the year, 7am to 9pm.

The facility is built for a full day, not just a swim. A Sauna Park spans 1,000 square meters with seven sauna types, there's a fitness center, and a medical center staffed for physiotherapy and rehabilitation alongside spa treatments. The treatment menu runs to Wai Thai massages, thalasso therapies such as mud wraps and pearl baths, and beauty services including facial care and hair removal. Seven specialised well-being centres are spread across the resort, which also includes a Beauty Centre.

Day visitors who aren't staying at one of the resort's hotels (Hotel Slovenija, Grand Hotel Portorož, Wellness Hotel Apollo, Hotel Riviera, Hotel Neptun, or Hotel Mirna) can still get in with a day pass. Booking for treatments or day visits goes through the wellness reception by phone or through the LifeClass website, which also lists current pricing. The place is set up with families in mind, with amenities geared to different ages and some programs noted as suitable for children with skin, respiratory, or joint conditions, alongside couples' packages for those after a quieter visit.
