Help with small deck ..

[Wao nahele kane]

Enclosing the underside of the tub will help contain the heat and give you an area that's enclosed to treat chemically for ants and other insects that like to hang out under hot tubs. So its typically best to skirt the whole hot tub from the support slab up to the rim with a mechanical access door. Build the deck around and up to that skirt. A good step over height for the deck over the rim is equal to the level of the seats in the tub, that way you are neither stepping up or down into the tub, you are stepping over the rim.
