This page identifies all you need to consider prior to your hot tub delivery. You will find the specific access dimensions and electrical requirements for your chosen model, along with relevant points to consider.

Aside from meeting the dimensional and electrical requirements, you will need an area of firm, level ground on which to site your spa.

Electrical Requirements

13 AMP Requirements

13 amp models require an outdoor waterproof plug socket with RCD protection within 1.5 to 4 metres of the spa location. Such sockets are inexpensive and simple to fit; a local electrician will typically supply and fit for approximately £75.

IMPORTANT : DO NOT USE AN EXTENSION LEAD OR PLUG TYPE CORDS OF ANY KIND. We cannot finalise the installation without the correct waterproof RCD plug socket.

32 AMP Requirements

These models require a 32-amp supply on 6mm SWA cable with RCD protection (cable sizes may be different depending on the length of cable run between the consumer unit and commando socket). A commando socket with local isolation is required between 1.5 meters and 3 metres of the spa, complete with ‘male’ plug and 8 metres of SY flex with UV protection or supply with flexible conduit). The flex is hard-wired to the spa by our engineers, then simply plugged in to complete.

A 32AMP dedicated electrical installation will typically cost around £300-£350 and typically take approximately two hours to complete.

* The commando socket supply DOES NOT require your electrician present on installation. However, a 32 amp ‘hard-wired’ supply WILL REQUIRE YOUR ELECTRICIAN PRESENT ON INSTALLATION to complete the wiring connection.

A new RCD circuit breaker must be used for your spa installation. Do not use an existing breaker, as its condition is unknown. The spa must be connected to a dedicated RCD breaker that is not shared with any other equipment. Do not use an extension or plug type cords of any kind.

The hot tub does not come with a plug and SY flex so please make sure this is supplied by your electrician.

40 AMP Requirements

A 40 amp supply using 6mm steel wired armoured cable with local isolation via rotary isolator, terminated with a 7 metre tail. A 40 amp breaker is required. The supply should feed directly from a suitable source (typically your domestic fuse box) to the rotary isolator which is typically mounted 2 metres from the spa area. A 7 metre ‘tail end’ is required from the isolator to the spa – the tail is ‘hard wired’ to the spa by an approved electrician*. Please note; the long tail is required to allow perfect siting and orientation of the spa. If the cable distance is longer than 20 metres, a 10mm SWA cable will be required – Please double check this with your electrician.


Spa Dolly

The spa dolly is a specifically designed hot tub installation tool. The dolly holds the spa upright, minimising the space required, allowing a safe and hassle free installation.
