Ground-level hot tubs are typically supported by a concrete slab, which should be formed and poured at the same time as the deck footings.
Suppliers are usually responsible for delivering and placing the hot tub, but it’s up to the deck builder to make sure the supporting structure is sized correctly and that necessary utilities are in place prior to delivery.
It sometimes takes a little extra time and ingenuity to deliver a large hot tub to its final destination. When hiring a crane, be sure the hot tub doesn’t exceed weight limitations, and that the crane has adequate reach.
When locating the hot tub, consider the climate, the way the clients will use the tub, and access to the rest of the deck.
Tubs that are mounted on the surface of the deck should have a set of steps, which should be removable to provide access to the tub’s pump and controls.
A spa table is a handy hot-tub option that can provide a place to sit and dangle feet in the water, or to set a drink. The table should be designed so that it doesn’t block access to the spa’s plumbing.
This deck was designed to have a removable section, since much of the hot tub would be below deck level.
