Yes, there are public changing rooms and toilets available at Hot Water Beach in the Coromandel, New Zealand. These facilities are located at the main (top) car park area, which is about a 100-meter walk from the section of the beach where the geothermic hot springs are found. After you finish digging your own "natural spa" and soaking in the 60°C (140°F) springs, you can use these rooms to swap your "togs" (swimsuit) for dry clothes. There are also cold outdoor showers nearby to help rinse off the sand and saltwater. In 2026, it is a high-value "pro-tip" to arrive at least two hours before low tide to secure a parking spot, as the area becomes incredibly crowded; if the main lot is full, you may have to park at the "Bull Paddock" overflow lot, which is a further 5-to-10-minute walk through a scenic bush track but further from the primary changing facilities.
