Preparing a Good Foundation
Your spa needs a solid and level foundation. The area that it sits on must
be able to support the weight of the spa, with water and the occupants
who use it. If the foundation is inadequate, it may shift or settle after the
spa is in place, causing stress that could DAMAGE YOUR SPA SHELL AND
FINISH.
Damage caused by inadequate or improper foundation support is not cov-
ered by the warranty. It is the responsibility of the spa owner to provide a
proper foundation for the spa.
Place the spa on an elevated foundation (preferably a 3” - 4” reinforced
concrete slab).
Pavers, gravel, brick, sand, timbers or dirt foundations are not adequate
to support the spa and will void your warranty.
If you are installing the spa indoors, pay close attention to the flooring
beneath it. Choose flooring that will not be damaged or stained.
If you are installing your spa on an elevated wood deck or other structure,
it is highly recommended that you consult a structural engineer or con-
tractor to ensure the structure will support the weight of 150 pounds per
square foot.
To properly identify the weight of your new spa when full, remember water
weighs 8.33 lbs. per gallon. For example, an 8’ spa holds approximately
500 gallons of water. Using this formula, you will find that the weight of
the water alone is 4,165 Lbs. Combined with the dry weight of the spa
you will note that this spa will weigh approximately 5,000 Lbs. when full
of water.
It is strongly recommended that a qualified, licensed contractor prepare
the foundation for your spa.
