Hot Tub Base

  • You must allow 1 metre clearance for access to the Hot Tubs access panels, for servicing.
  • The site you select for your Hot Tub MUST be a flat, level, continuous surface that contacts the bottom of your Hot Tub fully.
  • Your new Hot Tub weighs between 1100 and 1900 KGs (according to model) when full plus the weight of 6/7 persons and therefore a solid support is essential. 
  • A 10 to 15cm thick reinforced concrete slab is ideal but not necessarily required.
  • In most cases your Hot Tub can be mounted on existing patios which have adequate foundations for the Hot Tub loading. 
  • If in doubt consult an expert. It is recommended that you install your Hot Tub at ground level, which allows easy access to equipment. 
  • The base should be at least the size of the overall Hot Tub - see sizes on the technical data sheets. Note - If preparing a new location it may be worth extending the hard standing around your Hot Tub. This will allow good access for both maintenance and person entry, plus avoiding soil splash from water coming over the Hot Tub edge. Also, you may want to purchase a gazebo that also requires a level hard standing. 
  • Select an anti-slip surface for wet feet. Needs to be a durable waterproof finish. 
  • Avoid over hanging foliage that causes algae on the Hot Tub cover and makes the hard standing slippery.


  • The Hot Tub will arrive as a unit and cannot be dismantled. 
  • Ideally the Hot Tubs will be placed on a special trolley either on its side or on its base. 
  • Take note of the Hot Tub dimensions and make sure to add these to the relevant height, width and length of the trolley it will be transported on.
  • Soft ground, gradients or one or two steps must be ramped and boarded out by the buyer prior to delivery. 
  • It is very difficult to manoeuvre the Hot Tub up or down long flights of steps. If steps are involved please contact Pool Spas for further advice. 
  • Ensure there is sufficient width throughout the route, considering any gateways and all turns especially right angles. 
  • The Hot Tub on its trolley must be able to get around these. 
  • Walk the route with a tape measure and check that any protrusions or height restrictions will not effect the route taken by the Hot Tub and trolley. 
  • Beware of central heating vents and ducts, electric/gas meter housings, rainwater gutters and soil downpipes, low branches and foliage. 
  • If installation cannot be achieved via the specialist trolley system then either yourself or Pool Spas can arrange for a crane lift of the Hot Tub into your required location at extra cost. Call for advice.

Electrical connections

  • All Hot Tubs require a dedicated 240 volt, RCD protected electrical circuit that is permanently hard wired to the mains supply.
  • Check the spa specification regarding the power (e.g. 32 amp, 45 amp supply) or call us for advice.
  • Extension cords and plug-in type connectors must not be used. No other appliances or lights should be connected to this circuit
  • At the site where the Hot Tub is to be located, a local isolator must be placed 2 metres away from the Hot Tub.
  • 5 metres of cable should then be left for the final connection of the Hot Tub.
  • All electrical wiring to a Hot Tub MUST be installed by a qualified, licensed electrician and approved by local building/electrical inspectors or by a qualified ‘Part P’ approved company.
  • Water should always drain away from the Hot Tub. DO NOT locate your Hot Tub in a low run-off area since rain or melting snow could flood the area and cause pump and equipment damage.
  • DO NOT locate your Hot Tub near or under overhead cables, and clear of all electrical appliances.
