Hot Tub Location Planning
Outdoors

No matter where you install your new spa, it’s important that you have a structurally
sound, level and solid foundation to support it (grass is unsuitable). Structural damage
to the tub resulting from incorrect installation or placement on an inadequate
foundation is not covered under the spa’s limited warranty.
If you install the tub outdoors, a reinforced concrete pad at least four inches/10cm thick
is recommended for your Hot Tub.
In selecting the ideal location for your hot tub, we suggest that you take into
consideration:
 The proximity to changing area and shelter (especially in colder weather
conditions).
 The pathway to and from the hot tub (free of debris, dirt and leaves so as not to
be tracked into the hot tub).
 The closeness to trees and shrubbery (leaves and birds could create extra
work).
 A sheltered environment (less wind and weather exposure can result in lowered
operating and maintenance costs).
 The overall enhancement of your environment. It is preferable not to place the
hot tub under an un-guttered roof overhang since run off water can shorten the
life expectancy of the hot tub.
Deck
To be certain your deck can support your hot tub, you must know the deck’s maximum
load capacity. Consult a qualified building contractor or structural engineer
before you place the tub on an elevated deck or indoors. The weight per square
foot must not exceed the structure’s rated capacity, or serious structural damage could
result. . Please remember if you sink the hot tub in decking this will restrict both the
cabinet access and also access to the drainage point.
Indoors
Be aware of some special requirements if you place your hot tub indoors. Water will
accumulate around the tub, so flooring materials must provide a good grip when wet.
Remember also that hot tubs need to be drained approximately every 3 to 6 months
dependant on bather loads, so ease of drainage will need to be considered. If building
a room for the hot tub, it is recommended that a floor drain be installed. The humidity will
naturally increase with the tub installed. Water may get into woodwork and produce dryrot, mildew or other problems. Check for airborne moisture’s effects on exposed wood,
paper, etc. in the room. To minimise these effects, it is best to provide plenty of ventilation
to the spa area. Installation of a dehumidifier may be required. Please contact All Swim
for further advice and help with this.
If you decide to have your hot tub indoors please make sure that you have also allowed
sufficient ceiling height to allow clearance in your room for removal of your hot tub cover
and for your own height for climbing in and out of your hot tub. Please also ensure a
suitable allowance has been made for gaining access to the room for installing the hot
tub and that your chosen model will fit into the space – please see access requirements
for further information.
Additional Access Requirements
Service Compartment
Our Relax Essex service engineers may need to have access to the equipment inside your hot tub,
therefore you need to plan the position of the hot tub to allow easy access (we
recommend leaving a space of 24 inches or 60cm). If this is not possible then it should
be in a place where it can be easily moved when drained.
Cover Lifter
To make it easier to access your hot tub a cover lifter is highly recommended which
would enable a single person to uncover the hot tub. If you decide to invest in a cover
lifter it is recommended to leave an additional 400mm on each side of your hot tub to be
able to walk down the side and operate the cover lifter and then 600mm at the rear of
your hot tub for the storage area of the cover and cover lifter.
Steps
If you have decided to purchase hot tub steps, you will need to take into account how
much extra clearance you will need at the front of the hot tub. Please note: Hot tub steps
come in a range of shapes and sizes and some even have added drawers – this will all
need to be accounted for when positioning your hot tub.
Electrical Requirements
Any electrical point supplied for a hot tub indoors or outdoors should be installed by a
competent, certified electrician. All works must be certificated conforming to part P of
the building Regulations. Electrical installation work should always conform to BS:
7671 17th Edition of the wiring Regulations.
It is paramount that we see all certificates relating to the electrics that have been
installed by a certified electrician, if on the day we are unable to view the certificate; we
will only be able to complete a delivery and position and would charge for the second
visit to complete the install.
Most, if not all domestic hot tubs are designed for single phase 230vac operation. Your
certified electrician will then be able to work out what size of cabling is required. Even
the smallest tub would usually require at least a 16 amp supply. Bigger tubs with 3
pumps or more generally require a 40 amp supply but this is a guide only. Please
refer to the supply required for each of our hot tubs later in this guide.
ALL outside electrical supplies must have mechanical protection, this is either in the
form of steel wire armoured cable (SWA) or suitable conduit.
The hot tub MUST have its own dedicated circuit with correct size fuse breaker and
RCD protection. The RCD must be 30mA.
A rotary isolator switch not closer to the Hot Tub than 2 metres is required so that the
Hot Tub can be disconnected from the main supply quickly and efficiently.
We generally ask for a coil of 4 metres of cable to be left immediately next to the hot
tub base so that we have enough to wire it in whichever final position you have chosen.
We will need to know what colours have been used to identify Neutral and Earth. In
most cases Black is used but with the harmonised colours Grey is also sometimes
used.
A suitable gland to finish the SWA is required. Most hot tubs have a cable entry hole of
32mm so in some cases a 32mm – 25mm reducer is required. Please also leave a
suitable backing nut in order to fit the gland correctly in to the control box.
