(Alexandria, Va.) — The Pool & Hot Tub Alliance (PHTA), the trade association representing the swimming pool, hot tub, and spa industry, is inviting public review and comment on the proposed revision of the PHTA-6 Standard for Residential Portable Spas and Exercise Spas.

As an American National Standards Institute (ANSI)-accredited standards developer, PHTA follows a consensus-based standards development process that includes public review and comment opportunities for proposed standards revisions.

The draft revision of the PHTA-6 standard focuses on site-specific installation and consumer use of residential portable spas and exercise spas after delivery to the end user. Proposed updates are intended to improve enforceability, support regulatory alignment, address certification gaps, and enhance safety continuity throughout the industry.

The revised draft also includes updated language and new content designed to reflect current industry practices, technologies, and requirements.

The public review period for the draft PHTA-6 standard opens May 22, 2026, and closes July 6, 2026. During this time, industry professionals, regulatory agencies, and other interested parties are encouraged to review the draft and submit comments for consideration.

The public review announcement was published in ANSI Standards Action on May 22, 2026.
