Inspired by an Italian grotto (well, the word is Italian, after all ), the Grotto Sauna is a feat of old-world craftsmanship and new-world 
sustainability made possible by cutting-edge software and fabrication 
technology.  Designed by Partisans, the exterior is built from charred cedar prepared using a traditional Japanese method, balanced by the curved interior which has a nod to Austen Powers.
