GWI unveils latest edition of Hydrothermal Spa & Wellness Development Standards to elevate industry practices

28 May 2024
The Global Wellness Institute (GWI) has published the fourth edition of the Guide to Hydrothermal Spa & Wellness Development Standards

The 230-page guide, developed in collaboration with the GWI Hydrothermal Initiative* members, continues to set the industry standard for designing and constructing thermal experiences and wet areas in commercial and residential properties.

Originally published in 2014, the publication is designed to help stakeholders – including owners, operators and consultants – understand the complexity of these spaces.

Regardless of the size and scope of a project, the manual guides readers through everything from project planning to building and construction considerations, including recommended standards and materials, while clearly defining the functions and benefits of common thermal bathing and wet area experiences and treatments, both communal and private.

“I’ve long been convinced that, when implemented correctly, hydrothermal experiences play a key role in wellness programming, offering proven wellness benefits that are difficult to achieve any other way,” said Susie Ellis, GWI’s CEO and co-founder.

“Available for free download, the fourth edition of this resource has been updated and expanded, and includes crucial information to help anyone embarking on this type of build, whether for a home, spa, bathhouse or fitness centre.”

"Our main goal with this resource has been to provide information readers can’t find elsewhere,” said Don Genders, chair of the GWI Hydrothermal Initiative and CEO of Design for Leisure.

“This book is the result of a unique collaboration between experts, written to enable readers to walk away with a clear understanding of how hydrothermal areas should be designed and constructed, while also providing historical references, wellness benefits, practical tips, and even common building mistakes – all in an effort to elevate industry standards and encourage builds that are both high quality and sustainable."

In addition to the support from Hydrothermal Initiative members, sponsorship was provided by Accor and Hilton.
