I recently got a new hot tub and unfortunately the new hookup is about 2 feet further from where the old hot tub was. For various reasons it would be difficult to run new wire from the gfci breaker.

I know it would likely be against code, but would putting a waterproof junction box inside the hot tub cabinet be ok? Again, I understand it's probably against code, but is there really any reason not to do it assuming it is all waterproof and done correctly?

Adding a weather proof box at the tub is legal.

  • I agree. I can't think of any reason why that would be a violation unless you are modifying the hot tub's manufactured wiring. That would violate the listing. Just putting a waterproof j-box somewhere under the exterior of the tub seems just fine.

  • His question was "inside the hot tub cabinet" - but outside is a-ok (correct)?

  • As long as the tub is not modified the box could be mounted in a hollow space that is accessible or on the outside. I have done both in the past.

  • It depends how the hot tub is intended to be wired. If you're supposed to bring your own cables into the tub cabinet, then I don't see a problem. Commented Aug 26, 2017 at 20:38
