Survey of Float Tank Operating Practices

Abstract

Float tanks are public baths with high concentrations of magnesium sulfate that allow a person to float on the surface of the water. Float tanks are relatively new in the United States and are thus under‐researched. Little is known about how they are operated to maintain a safe swimming environment. The lack of data on float tank operations makes regulating float tanks difficult for public health departments that oversee the safety of publicly used spaces, like swimming pools. The goal of this study is to gain an understanding of typical float tank operating practices by issuing a questionnaire on water treatment, testing, replacement, and other maintenance methods. A survey was completed by 53 float tank operators 114across the US. Results from this study will help guide public health policy efforts aiming to regulate float tank operations.
