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 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 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 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.

Note:  It  is  strongly  recommended  that  a  qualified,  licensed  contractor 

prepare the foundation for your spa.

• 

area chosen.
