Electrical Access Guide For Saunas

For saunas using a wood burning stove we recommend using a 13amp (fitted with a 5 amp fuse) fused spur positioned to the rear of the sauna or up to 1M away with 5M of 1.5 3 core H07 flexible cable for us to run the lighting circuit from, the lights will only use around 30W.

For saunas using an electrical heater we recommend an independent RCD or RCBO that only powers the sauna. A 40amp type B MCB must provide overcurrent protection. Cable size depends on the length of the run/route normally we tend to see 6-10mm cable being used, longer cable runs are in 10mm SWA. If your cable is to be ran externally we recommend a cable with mechanical and UV protection such as steel wired armoured cables or similar. You may also need an earth rod depending on your earthing system- this is down to your electrician to carry out a valid risk assessment. Finally, you will need an external isolator, we advise a 40-45amp rotary isolator with a IP67 rating it is required to be at the rear of the sauna with access to turn it off. To the left or right of the sauna is acceptable just incase the sauna is positioned tight up against the wall or fence please check this before positioning the isolator. Once in place leave 7M of HO7 black flexible cable heat resistant from the isolator, your electrician must connect this up into the isolator itself – we will connect the other end of the cable to the sauna heater. If your isolator is placed more than 2m away from the sauna location, add this to the 7m length of cable you leave for us. This must be safely isolated from the supply and left dead for us to perform the electrical connection onto the sauna heater.

We recommend using a 13amp fused spur (fitted with a 5 amp fuse) positioned to the rear of the sauna, you can use the same supply as your sauna heater and position this right next to isolator, or up to 1M away with 5M of 1.5 3 core H07 flexible cable for us to run the lighting circuit from, the lights will only use around 30W max

Your electrician must provide an electrical installation certificate and notify local building control of the works carried out.

Any installations we see on installation that does not have valid electrical test certification may not be connected if we deem the installation unsafe.

The advice we give regarding electrical requirements is always given as advice and you should in every occasion consult an electrician to ensure regulations are complied with.

 

Base sizes are guidance only and you can make them bigger if you wish

Cube/barrel 160 – 2000mm x 1600mm    *Total weight 800kg*

Cube/barrel 210 – 2000mm x 2100mm.   *Total weight 800kg -900kg*

Cube/barrel 250- 2000mm x 2500mm.   *Total weight 900kg – 1000kg*

*weights are calculated before bathers are inside*

You can place your new sauna on an existing base of decking or paving but usually this is designed and built with fall to run water off so will result in your sauna not being level when we install it. Packers can be used to prop up the sauna but we can only use the wood its made from to do this. We recommend a purpose built solid concrete base 100-150mm thick which is screeded level with minimal fall / run off for surface water. The more level the surface the better for your new sauna.
