Hello. I reside in southern Germany. I've been looking at the Röger Origo sauna in the 140x200 configuration: https://www.roeger-sauna.de/sauna-kaufen/sauna-origo.html Cost is ~5000 EUR.

Does anyone have experience with Röger or this particular sauna ?

I've also contacted some local electricians .... and they would run a cable tray along the ceiling for the 400V connection. I suppose that's normal in the German concrete homes ?

Thanks!
