Portable Spa Site Preparation
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.
Note: Damage caused by inadequate or improper foundation support is
not covered 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” concrete
slab). Pavers, gravel, brick, sand, timbers or dirt foundations are not
adequate to support the spa. If you are installing the spa indoors, pay
close attention to the ooring beneath it. Choose ooring 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 wa-
ter weighs 8.33 lbs. per gallon. For example, an average 8’ spa spa holds
approximately 500 gallons of water. Using this formula, you will nd 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.
Note: It is strongly recommended that a qualied, licensed contractor pre-
pare the foundation for your spa.
