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 nish.
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 3” - 4” concrete slab.
Pavers, gravel, brick, sand, timbers or dirt foundations
are not adequate to support the spa.
We strongly recommend that a qualied, licensed
contractor prepare the foundation for your 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 contractor
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 average 8’ 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.
