Which metal parts of therapeutic tubs are required to be bonded together?

Equipotential bonding is used to keep all metal parts in and around a tub at the same electrical potential so a fault can’t create a dangerous voltage difference for someone touching different parts. For therapeutic tubs, this means tying together every metal fitting within or attached to the tub structure and every metal part of the electrical equipment that’s part of the tub’s water circulating system, including pump motors. If any of these parts were left out, a fault could energize one metal piece while another remains at a different potential, creating a shock hazard in the water or on contact with the tub. Bonding all of these parts to the same bonding network (and to the building’s grounding system) ensures that no dangerous potential difference exists between them, which is why the best answer is to bond both categories of metal parts. Grounding and bonding serve different roles, but bonding all relevant metal components is the key safety measure here.
