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 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 to 4” / 30 cm concrete
slab. Pavers, gravel, brick, sand, timbers or dirt
foundations are
not
adequate to support the spa.
We strongly recommend that a qualifi ed, licensed
contractor prepare the foundation for your spa.
If you are installing the spa indoors, pay close
attention to the fl ooring beneath it. Choose fl 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 (732 kg / m2).
To properly identify the weight of your new spa when
full, remember water weighs 8.33 lbs. per gallon, or 1
kg per liter. For example, an average 8’ spa spa holds
approximately 500 gallons, or 1892 liters, of water.
Using this formula, you will fi nd that the weight of the
water alone is 4,165 lbs, or 1892 kg. Combined with
the dry weight of the spa you will note that this spa
will weigh approximately 5,000 lbs, or 2267 kg, when
full of water.
