Anyone have a sauna installed in their Brooklyn home?

Hi there. When we bought our house it came with an old sauna. I probably wouldn’t install a sauna from scratch but since there is one there, and the space is somewhat awkward and not usable for much else, I am looking into having a new, workable, more energy efficient sauna installed.

Has anyone had a sauna kit installed in their Brooklyn home? Looking for a sauna installer or a contractor who has had experience installing sauna kits.

Much appreciated.
