I'm installing a whirlpool bathtub and just want to make sure I do the wiring correctly. I will be installing 2 separate 20 amp single outlets underneath the tub next to the motor. With those being fed from 2 openly accessible dead front gfci's in the bathroom which will feed from 2 20amp breakers. My biggest question is, is any conduit required for this? All of the wiring will be behind drywall and cement board except what is below the tub rim which is exposed but enclosed from the tub surround. Any advise would be appreciated. Thanks
