ECN Forum Forums Photo Discussion Forums Photos for General Discussion Hot tub install - Separate Structure?

This is a hot tub I installed a few years back. Located about 30 ft. from the house, it is a pre-fab unit (with a styrofoam "pad"). The "gazebo" is open all around, only acting to keep the sun off the cover. The gazebo is all wood.

Would you consider this to be a "seperate structure," like a detached garage, that would require a ground rod, in addition to the ground wire?

As a side note, I had needed to bring the power for this out one side of the house, up and across the roof, and back down. In the second pic, my pipe is a little to the right of the much more visible drain pipe, visible near the gardener's hat.
