AbOvE-GROUND INSTALLATIONS
Where the hot tub is a "stand-a-lone" above-ground
installation to be installed in regions where freeze/thaw
conditions may occur, a level patio stone or pre-formed
paver type base may be sufficient if there is no abutting
deck(s) that could be damaged during potential seasonal
movement of the ground. The potential drawback to
this type of base is that splash water could eventually
de-stabilize the ground under the base, with the resultant
shift of the support base causing damage to the hot tub
structure.
For best results, we recommend the installation of a level
concrete pad:
• Dig out and level the ground 20-30 cm (8-12 in.) below
your desired base level
• Install 10-15 cm (4-6 in.) of crushed stone
• Next, install 10-15 cm (4-6 in.) of poured concrete
• Level the concrete and apply a broom-type finish
• We recommend that the pad be made 15 cm (6 in.) larger
than the hot tub on three sides, and 1 m (3 ft.) larger
on the side where the access steps and/or planters will
be installed
In regions where freeze/thaw occurs, or where there will
be custom decking abutting the hot tub we recommend
the installation of sono-tubes beneath the pad to prevent
shifting.
IN-GROUND & PARTIAL IN-GROUND
INSTALLATIONS
For units being installed fully or partially in the ground,
the type of support will again vary based on whether or
not the tub is being installed in an area with freeze/thaw
conditions. Hydropool does not recommend back-filling full
in-ground or partial in-ground installations.

After the hot tub is properly positioned on the support base,
the entire unit should be checked with a level and shimmed
as necessary. Should you find that the support base is sloped
or otherwise uneven, level your hot tub using TAPERED
wood shims where necessary, ensuring that the tapered
end extends at least 61 cm (24 in.) under the unit. This

• Non-freezing climates – it is sufficient to ensure that the
base of the hole or cavity created for the tub has a dry,
stable, compacted level base and proper drainage
• Climates where freeze/thaw occurs – it is neces-
sary that a poured level concrete base, complete with
concrete footings, be installed as outlined in the section
ABOVE-GROUND INSTALLATIONS - p.6.
• Areas with a high ground water table – a level concrete
base, as well as a concrete or wood retaining wall to
hold back the earth, is recommended. This forms a box or
'bunker', in which the hot tub is placed
• ALWAYS ensure that there is good drainage, via a
properly designed French drain (gravel) system and/or a
sump pump, to prevent ground water flooding damage
to the support equipment or hot tub structure
• Install protective waterproof conduit to house light,
or topside control cables that will be buried
• Access for future service must be considered at the
time of design and installation. Difficult access can
result in supplemental service labour charges not cov-
ered by the factory warranty. Consider easily removable
deck materials.

OvERALL SUPPORT

Your Hydropool hot tub is equipped with a factory
installed load support substructure, which distributes the
weight of the water over the entire foot area of the hot
tub. The cabinet, either factory installed or customized
on-site, should be decorative only, and not relied on for overall
support. Never suspend a hot tub from a deck or floor by
the outer acrylic edge, as this will lead to product damage
and/or serious personal injury.

will insure contact with the support substructure to
appropriately distribute the weight of the unit. Do not
just shim under the cabinet base outside edge, as this will
cause structural stress on the unit, potentially causing
unwarrantable damage to the hot tub structure and /or
shell.
