Spa foundation
General Guidelines: Select a structurally sound flat surface that is reasonably
level to serve as your spa’s foundation. A foundation that shifts or settles may
cause stress to the spa shell. The foundation that your spa rests on must have a
weight bearing load capability of supporting the weight of your spa, its water,
and the people using it. The maximum filled weight of a spa can be as much
as 6,000 lbs. (2,800kg), plus the weight of the occupants that use the spa (for
the weight bearing load requirements as well as the maximum filled weight of
your spa, refer to the Spa Technical Specifications Chart or contact your local
authorized Bullfrog Spas Dealer). If your spa’s pad is slightly sloped it may not
affect the performance of the spa or its structure, however, there should be no
dips, sags, or unevenness in the pad. Most patios are built to slope away from
the house for drainage purposes. There should be no more than a 1/2” (1cm)
slope in an 8 ft (2m) run. Recommended flooring materials include a concrete
pad, concrete pavers or bricks, pea gravel, or crushed rock 1.5” (4cm) or less, or
a reinforced deck. Additionally, your authorized Bullfrog Spas Dealer should
sell or recommend pre-formed spa pads.
NOTE:
Concrete foundations should be a minimum of 4 inches (10cm) thick
and should be reinforced with either rebar or mesh. For electrical grounding
purposes, the rebar or mesh should be attached to a bond wire (see Electrical
Requirements and Installation Instructions).
WARNING:
To prevent serious damage to your spa, it is important that
the spa foundation be supported by a flat, stable, and consistent subsurface.
Bullfrog Spas International highly recommends consulting a qualified, licensed
Contractor prior to the installation of any spa foundation. For assistance,
contact your authorized Bullfrog Spas Dealer.
WARNING:
Because your spa pad must provide continuous support for
the entire base of the spa, you should never level it with shims. If it is
necessary to level your spa, make sure the entire spa’s structure is fully
supported, both in the center as well as the outer edge. When leveling your

spa, there should be no voids beneath it. Contact your authorized Bullfrog
Spas Dealer before making any leveling adjustments. Structural damage to the
spa resulting from incorrect installation, placement on an inadequate
foundation, or improper leveling will void the spa’s warranty.
