Everything you need to consider before your Hot Tub / Spa is
When finding the best location for your hot tub or swim spa,
think safety first: Never position a spa, swim spa, or any other
type of pool near overhead cables or power lines. Make sure that if
the spa or swim spa is to be positioned near a slope, dip, trough
or below ground level, there is adequate drainage for any ground
water to run off. In this instance we recommend a land drain around
the four sides of the spa. Damage caused by flooding is not covered
If you are building a deck around the tub, sinking it slightly,
or placing it against a wall, ensure easy access is provided to the
service panel. This is almost always on the same side of the hot
tub as touch pad. You must ensure that it is possible to drain the
hot tub and move it to gain access to the other three sides if next
to a wall or other object. Proper planning will enhance the
enjoyment of your spa experience and protect your privacy.
Do you need quick and easy access? If so, placing spas close to
the house or changing room is ideal. Perhaps you want extra privacy
by adding a gazebo? Do you have a view to admire from the spa? If
so; consider how the spa can be best rotated so the seating faces
the view without obstructing the service panel.
Inside or outside?
Our spas are designed specifically to be used outdoors, however
some customers choose to install them inside anyway. Customers
intending to do this are advised to consider the following
1. Will the floor take the weight of the spa? Consult a
structural engineer if in doubt
2. Is the floor waterproof? A fully waterproof, sealed, concrete
floor is OK, timber joists may not
3. Is there adequate floor drainage? This must be sufficient to
contain a sudden escape of water
4. Is there adequate ventilation? Extractors, dehumidifiers and
air conditioning reduce condensation
5. Is the flooring material chemical resistant? Most ceramics
are OK, lino or vinyl may bleach or stain
6. Is the flooring material non-slip? Make sure you are creating
a safe environment around the spa
7. Is the electrical supply safe for indoor use? Indoor
installations have more complex requirements. Your warranty, and
electrical certificate may become void if the above is
Recommended foundation or base
Your spa needs a solid, flat, level foundation. The space it
sits on must be able to support the weight of the spa, the water in
it, and those who use it.
If the foundation is inadequate, it may shift or settle after
the hot tub is in place, causing stress to the shell and cabinet,
voiding the warranty.
Your spa will weigh anything between 1200kg and 2500kg (that's
between 1.2 and 2.5 tonnes, the same weight as an average family
car or 4x4)
Also consider the surrounding surfaces
Block paving is often laid with sand which can be a problem as
the sand is trodden into the spa water and can damage internal
components. Decking is a good clean surface to use, but can become
slippery when wet, and gravel can be uncomfortable on bare feet. By
minimising dirt entering the hot tub on bathers' feet, your water
will look better and last longer.
All our spas require a mains power supply to be installed by a
registered electrician. You must arrange for an electrician to
install all of the power supply prior to our arrival to site, just
leaving a three metre "tail" of excess cable next to the intended
location of the spa.
We cannot, will not, and are not insured or qualified to modify
the electrical connection in any way . This is for your own safety
and protection - It is the law.
Your crane company will always visit your property to assess any
potential access problems and to ensure that the intended site is
within safe reach. While hot tubs can often be lifted without
spreader bars, this is at the discretion of the crane company,
although we insist that they are used for lifting swim spas (more
swim spa info below). It is the sole responsibility of the crane
company to ensure that the product is moved without damage, and it
is your responsibility to ensure that they are suitably insured for
damage occurring to either your hot tub or your property. We cannot
and will not be held responsible for any damage to persons or
property while the product is in the air, or while the crane is
Sinking your pool into the ground or decking around it
Decking can create stunning visual effect, and by stepping down
in to your spa or swim spa, you benefit from added privacy and
If you are planning to do this, we strongly advise that you read
on, before you purchase the item. If this is not done properly, it
can be equivalent to welding your car's bonnet shut!
All spas and swim spas require access to the service panel,
however when the item cannot be freely moved (ie: it is sunk in a
pit or decking), sufficient access for our engineers is needed for
us to service your spa. We recommend you allow at least 600mm
clearance around all four sides for spas and 900mm for Swim Spas .
The spa below, has been installed in such a way that access can be
provided to all four sides by moving the spa, if needed.
If you are decking around the spa or swim spa, we strongly
advise that you do this after the item has been delivered. Swim
Spas cannot be moved without a crane, so it is important that they
are spaced at least 800mm from any buildings, fences or retaining
walls to ensure sufficient access to all panels.
When decking around your new pool, we advise that you place
upright supports at regular intervals around the spa, set back
600mm, then cantilever the joists so that the deck is
self-supporting around the item. This way our engineers can access
any service panels as required .
Access requirements for our delivery and installation
Sometimes a lack of planning prior to delivery can create
problems when we position the spa in your chosen location. You must
compare the dimensions of the spa (and the trolley) to any
restrictive points along the delivery route used to bring the spa
into your garden. Sometimes a fence panel can be removed and the
hot tub can be delivered via a neighbours' garden (with their
Alternatively, your local crane company will often be able to lift
it into position for a few hundred dollars. We will gladly work
with the crane company of your choice to do this, (unless
specifically stated otherwise, the cost of a crane is not included
in the delivery).
For normal deliveries:
1. The spa is delivered on-end using a purpose-made trolley,
adding 2cm to the height clearance
2. You must add the width of your spa to the height of the
trolley to work out the total height needed
3.The hot tub will generally be around 95cm wide when on the
4. The total length of the trolley (3.2metres) must be
considered for tight corners - it will not bend!
5. Because the trolley ground clearance is under 20cm over a 3m,
steps or lifting will require extra men
Other things you should check include:
A. Lots of steps? Call us.
B. Corner clearance
C. Overhead branches
D. Protruding buildings
E. Gates: height and width
F. Overhanging gutters
G. Boxes, steps or vents Remember to add 20cm to the height of
the hot tub when on-end to allow for the trolley's height
Swim Spas have very specific installation requirements over a
normal spa due to their immense size and weight. A Swim Spa full of
water will weigh 7 - 10 tonnes, around the same weight as the lorry
that is used to deliver it!
Foundation: 200mm thick Concrete, with reinforcing mesh, laid
onto well compacted hardcore
Positioning: This MUST be done with a crane. The crane company
MUST supply spreader bars (these bars push the lifting slings apart
above the swim spa so that it is not crushed under its own weight).
We advise showing this info to them
Power Supply: This is normally 45amp unless stated otherwise
Site Access: The Swim Spa is delivered on a flat bed truck. Your
crane company will need to ensure that there is sufficient access
for their vehicles as well as the delivery vehicle.
Access Panel: This is always at the same end of the swim spa as
the seats. The whole end panel of the swim spa should be easily
removable for servicing, and 900mm access must be provided on all
sides. When decking around the swim spa after installation, care
must be taken to ensure that supports do not obstruct access to the
removable panels - see the decking section above.
