Gravity on High Street in Northcote calls itself Victoria's first and largest float centre, with over ten years behind it and more than 75,000 sessions logged. Alongside the float tanks it runs a private far-infrared sauna room held between 38°C and 58°C, and contrast therapy that alternates a traditional sauna with an ice bath in guided intervals. Massage, red light and PEMF therapy sit alongside, and it is a registered NDIS provider.
