680.70 does not say any thing about a disconnect for the tub motor-Does the code say a discoonect is need such as a toggol switch - 20amp 125v. on the bathroom wall for the motor??

Zapper;
part VII blows off the rest of 680....

VII. Hydromassage Bathtubs
680.70 General.
Hydromassage bathtubs as defined in 680.2 shall comply with Part VII of this article. They shall not be required to comply with other parts of this article.

while asking to comply with chap's 1-4..

680.72 Other Electrical Equipment.
Luminaires (lighting fixtures), switches, receptacles, and other electrical equipment located in the same room, and not directly associated with a hydromassage bathtub, shall be installed in accordance with the requirements of Chapters 1 through 4 in this Code covering the installation of that equipment in bathrooms.

which would bring us to 430 & disco's, right?

In my experience no switch is needed. They are cord and plug connected so that covers your disconnect. I do usually install one anyway. Just seems like good safety practice. Also some manufacturers instructions suggest that you provide a safety switch.
