Just ordered a spa, and need to cut a square hole in my deck to accommodate the tub. The stated dimensions on the model are 84x84x36. Are these the exact measurements at the widest points of the spa? I'm not sure manufacters differ in how the measure, or whether it includes the shipping/packaging.
Also, let's say the true width is 84" of the tub, and it is square. How big should I make the gap between the edge of the spa and the deck boards? My installation will have the spa be about 4" higher than the deck boards. Not sure if I need to account for access to the panels from above. I will be able to go underneath the deck to access the panels, though.
Advise appreciated!
