In a sauna we regularly go to, the bath attendants bring along Bluetooth speakers and control them via their phone/smartwatch. At least the infusions seem to survive unscathed
yes, during my last sauna visit, a guest had brought something like that along. But he turned it off as soon as I was inside, before that he was alone... I would prefer something permanently installed, preferably with internet radio and voice control (which I use at home in the bathroom and in the office or the workshop there).
And for lighting, I would prefer dimmable LED panels (or strips under the benches?) for mood lighting like I once saw in a BIO sauna. There were several LED panels on the ceiling and one wall that changed colors very slowly for relaxation.
By the way, the roof definitely has to be on, it’s not watertight otherwise. I don’t want any more curved corrugated iron, I like curved standing seam sheet metal even better. If it is reasonably affordable (budget is about 1500 for the roof), it will be something like that in aluminum white or gray-white. Copper will probably be too expensive, which would of course be super cool. From tomorrow on, I will inquire whether a regional roofer here can do something like that, otherwise it will be custom ordered.
