New Standard For Custom Spas, Swim Spas

Scott Webb Headshot

APSP has announced a newly revised standard covering custom, inground spas and swim spas. This standard does not concern factory-built portable spas or factory-built swim spas, nor does it cover public spas.

Major changes from the previous version of this standard from 1999 include the addition of permanent inground “swim spas,” which has caught the attention and excitement of consumers. “A swim spa provides a wonderful opportunity for homeowners who are challenged with limited backyard space to enjoy the recreational and health benefits of not only a pool but a spa all in one,” says Carvin DiGiovanni, senior director, technical and standards for APSP.

The revised standard also includes the latest safety and energy requirements to ensure the highest degree of safety and operating efficiency. For example, a new Appendix B on Water Velocity Limits has been incorporated to assist pool designers and builders on how to determine the required design flow rates — essential to energy efficiency and bather safety. 

“Contractors who are building, renovating or remodeling permanently installed spas or swim spas should use the new standards to provide their customers with the minimum guidelines for such a project,” said DiGiovanni. “The design requirements and construction practices outlined in the Standard are based upon sound engineering principles, research and field experience that, when applied properly, contribute to consumer satisfaction and safety in the final product.”
