Hot Tub Removable Deck Panels
When planning you hot tub location you will need to make sure you have serviceability for the front of the Spa. Dropping a hot tub into a deck requires a removable panel for just that. Shown below is a Grandee Spa by Hot Spring Spas up against 2 sides of a deck. Behind the Spa there is a privacy wall. So there are two sides accessible for service and the front is accessible with a removable floor panel. If you do it right you it will look invisible.
Behind the Spa is where the Cover Cradle sits once the Spa is open:
Here is the view from top of the deck:
Notice the notch out for the Cover Cradle:
