John, George spanked me about this a while ago, go pick out a switch. wink
Those jetted bathtubs are covered by 680 part VII not the spa rules
This is the commentary from the handbook that sums it up.

Quote
Hydromassage bathtubs (see definition in 680.2) are required to be protected by a GFCI. In addition, all 125-volt, single-phase, 15-, 20-, and 30-ampere receptacles within 5 ft of the inside wall of the hydromassage bathtub are required to be GFCI protected. Hydromassage bathtubs are treated the same as ordinary bathtubs in regard to the installation of luminaires, switches, and other electrical equipment. See 410.4(D) for special requirements relating to cord-connected fixtures, hanging fixtures, and pendants near bathtubs. Also see 210.8(A)(1) and 210.8(B)(1) for requirements for GFCI protection of bathroom receptacles.
