Providing a local earth to distant circuit

[Sparky Chris]

Hi and thanks for reading and any helpful response.
I need to wire up an 11kw sauna heater about 60m from the main fuse board in the house. I thought I could run live and neutral in 16 mm in 25mm conduit the 16mm allowing for voltage drop over such a long run. My main question is could I put in an earth stake near the sauna thereby savin

Questions
Inside or outside?
Galv or Plastic conduit?
Protective device ?

OK thanks so much. The 60m run is outside and Underground in pvc conduit I expect the run to be protected with a 100ma rcd to the sauna board then a 30ma rcd for the sauna heater and lights.

Singles on pvc conduit underground sounds a bit ropey. Can you not use SWA?
