INDOOR INSTALLATIONS
• When the hot tub is to be installed in a small room
(under 150 ft2/14 m2), we recommend that large units be
fully or partially submerged in-floor so that it does not
dominate the room. This is to allow sufficient headroom
for entry and exit to and from the hot tub
• It is beneficial if the hot tub room is located near wash
room and shower facilities
• The hot tub room should have a floor drain to handle
spillage, a window, outside exhaust fan or humidistat
controlled exhaust fan for ventilation. Where this is not
practical, the use of indoor/outdoor carpeting or a tile
floor and the opening of a window while the hot tub
cover is removed should be sufficient. You should not
have concerns regarding humidity. When the hardcover
is installed, no humidity will escape. During use, the small
amount of humidity released into the room can be
removed with the use of a small dehumidifier
• Consider plumbing a fresh water tap nearby and a
permanent drain location for the hot tub to eliminate
having to use a long garden hose each time you fill or
drain the hot tub
• Always provide adequate ventilation for the support
equipment
• Consult your local dealer for further information
OUTDOOR INSTALLATIONS
• Contact your local building code department to
determine if a building permit is necessary and for
information on applicable bylaws (distance from property
lines, buildings, fencing requirements, etc.)
• If you are doing any excavating, contact your local gas,
hydro, and cable-company to ensure that there are no
underground lines
• Locate the hot tub, where practical, within close distance
of a door to the house, to maximize potential winter use.
• Ensure that your pump(s), controls, drain-valve and
thermal probe are easily accessible and protected
• If possible, locate the hot tub where you will enjoy
some privacy, out of the site of neighbours. If this is not
possible, a partial privacy or wind partition, or proper
placement of the optional Hydropool cover lifter should
provide adequate privacy
Hot tub equipment is generally designed for indoor (out of
the direct elements) use. When your HYDROPOOL hot tub
is equipped with a factory-installed cabinet, and installed
as per the guidelines of this manual, the equipment is
adequately protected. If the hot tub is shipped without
a cabinet, your custom cabinet or other structure must
be designed to supply protection for the hot tub support
equipment from rain, snow, splash water, etc., but still
designed in a manner to ensure adequate ventilation.
SPECIAL CONSIDERATIONS FOR…
ABOVE-GROUND INSTALLATIONS
Where the hot tub is a “stand-a-lone” above-ground
installation to be installed in regions where freeze/thaw
conditions occur, a patio stone or pre-formed paver type
pad may be sufficient if there is no abutting deck(s) to
be damaged during potential seasonal movement of the
ground. The drawback to this type of base is that splash
water could eventually de-stabilize the ground under the
pad, with the resulting support base shift causing damage to
the structure.
For best results, we suggest 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
future shifting.
