Although they may increase property value, the main reason to build a deck is leisure; sundecks are about creating a space for family and friends to make the most of leisure time in the great outdoors. And one of the best ways to maximise this leisure potential is to include a hot tub in your deck. Hot tub deck design will vary depending on the size, shape, and orientation of the house and the yard, as well as the location of the tub. Hot tub deck design call for the hot tub to be placed on the deck itself, with steps or platforms built up to the lip of the tub to provide easy access. Others call for the hot tub to be placed on the ground beneath the deck, and the deck itself is built to the height of the top of the tub, again allowing for easy access.
