How to Find your Spa Serial Number?

Typically, your spa serial number decal will be inside the hot tub equipment compartment, attached to the spa shell wall. It will say the Manufacture Name (Watkins, or Jacuzzi), the Model Name, and then a Serial Number.  If you have any questions of how to locate the spa SN, or how to determine information of your spa by its SN, please email us.
