Flexum Thermal & Spa in Mosonmagyaróvár is internationally recognized for its highly concentrated medicinal water, often cited among the most effective in Europe for therapeutic use.
The thermal water, emerging from deep wells at high temperature, is rich in minerals such as sodium, calcium, and hydrogen carbonate. It is used to treat musculoskeletal disorders, degenerative joint diseases, and certain neurological conditions.
The spa includes indoor and outdoor thermal pools, swimming pools, and a wellness area with saunas, steam baths, and massage services. A dedicated medical wing provides supervised treatments including balneotherapy, physiotherapy, and mud therapy.
Its proximity to Austria and Slovakia makes it particularly popular with international visitors, positioning Flexum as a cross-border medical spa destination rather than a purely recreational bath.
