The Pool and Hot Tub Alliance (PHTA) announced the upcoming review and revision of ANSI/APSP/ICC-6 2013 (R2023) American National Standard for Residential Portable Spas and Swim Spas, and calls for participation in the new PHTA-6 Standard Writing Committee (SWC).
The PHTA-6 SWC is updating the standard, which outlines recommended minimum guidelines for the design, equipment, installation and operation of residential portable spas and swim spas. This standard also serves as a resource for local authorities and regulatory agencies in establishing criteria for these types of residential spas.
The SWC will meet under the American National Standards Institute (ANSI) periodic maintenance process to review and update the standard. Subject matter experts interested in joining the SWC should be prepared to actively engage in in the language drafting process and possess a solid understanding of the existing standard. The project is expected to take about one year to complete.
All stakeholders, such as designers, builders and manufacturers of residential portable spas, exercise spas and hot tubs; equipment and component manufacturers; building code officials; and consumers are invited to apply to serve on the PHTA-6 SWC. PHTA seeks to establish a diverse SWC for a reasonable balance between all interest categories, individuals and organizations. Some priority will be given to applicants who have experience using, applying and enforcing the APSP-6 2013 (R2023) Standard. Read more about how to participate in the process, or complete the application to serve as a PHTA-6 committee member here.
Those who are not subject matter experts or active users of the standard are welcome to participate as observers in the meetings throughout the revision process.
Stakeholders are also invited to submit change requests to the existing APSP-6 Standard for inclusion in the revised standard. These change requests will be reviewed by the PHTA-6 SWC. Change requests can be submitted here and must be submitted by Aug. 31, 2025 to be considered during this revision cycle.
Completed SWC application forms must be submitted to PHTA by July 11, 2025.
