Placement of spa will determine how close spa will need to be placed to reach outlet. Please refer to the ‘PREP’ tab on this site’s page for your particular spa model to see the cord placement. The cord will be connected to the ‘Control Pack’. Longer cords are available for purchase at $1.75 per foot with a maximum length of 40 feet.
